Exciting Times for LonMark 

and Open Systems 

New partnerships, new opportunities, 

and new programs 

are at the forefront of our current 

activities. We continue to achieve 

our goals of better education, market 

awareness, and promotion for our 

member products and services. 

In this quarter’s issue of the 

LonMark Magazine, you will learn 

about new uses for LonWorks within 

non-traditional applications ranging 

from irrigation control to TV production 

studios, and from military installations 

to IT integration. This issue focuses 

on the broad reach of solutions 

outside the box; outside the building, 

and into the process. As more and more 

systems require interaction beyond just 

the typical building automation system, 

solutions are arriving on the market 

that do more, that integrate better, 

and that deliver more efficient systems. 

Everyone at LonMark International 

has been very busy over the past few 

months delivering on our plan to update, 

inform, and educate. 

Strategic Partnerships 

Last year, we announced a program to 

broaden LonMark’s relationships with 

other organizations, associations, and 

alliances to further our growth and 

to further the adoption of LonMark 

open systems. Our first partnership, 

Constellation’s NewEnergy Alliance SM , 

has been a great success, supporting 

the energy and Demand Response 

market. If you’ve seen earlier issues of 

the LM Magazine you’ve read about 

the efforts to develop DR profiles and 

interfaces to the intelligent building 

systems. The NewEnergy Alliance SM 

team is involved in the process as is our 

Technical Director, Jeremy Roberts. 

We invite anyone interested in this 

market to participate in the ongoing 

working group dedicated to supporting 

this effort. 

In September, LonMark announced 

a new partnership with the EnOcean 

magazine|4.2008 

Alliance supporting the low power 

RF solution pioneered by EnOcean 

Corporation. This new partnership 

seeks to develop the required system 

infrastructure and open architecture 

to drive intelligent sensors on an RF 

network into an open LonMark system 

design. The partnership strives to 

develop open, interoperable, multi-vendor 

solutions for this rich and growing 

segment of the controls market. 

Updates 

Early last year, you may remember 

we invested heavily in our new web 

presence. Our then sorely out-of-date 

website is now the talk of the town 

with its robust, easy-to-navigate interface 

and wealth of information, tools, 

and resources. Recently, we’ve added 

a section where you can search for a 

LonMark Certified Professional in 

your area (over 250 listings!). We’ve 

improved the events calendar pages, 

added new resources, and just recently 

added a new section for our strategic 

partnership information. Here you will 

learn about the New Energy Alliance SM 

and EnOcean Alliance relationships. 

This summer’s project was less visible 

but equally important to our increased 

growth. Our back-office databases 

have now been merged, updated, 

and streamlined. This includes our 

member database, product database, 

certified professional database, and 

more. All are now running on the latest 

SQL Server…no longer are we using 

multiple systems on multiple boxes 

with multiple interfaces. This effort 

will help us manage requests in a more 

timely manner, provide seamless integration 

of our systems, and help support 

our growth plans. 

Training/Testing 

You asked for it, so we are delivering! 

After a very successful launch of 

the LonMark Certified Professional 

Credentialing Program, we were asked 

Ron Bernstein 

to deliver a comprehensive review class. 

This new, one-day class covers the fundamentals 

of information needed to 

sit for the exam. It is a review class 

for people already familiar with the 

technology and who have had industry 

experience, but just need a refresher to 

feel comfortable passing the test. This 

training is now being offered worldwide 

at local training/testing centers as 

well as at industry trade events. Also, 

we just launched our on-site training/ 

testing service where one of our trainers 

will come to your site to train/test 

your staff. If you are interested in becoming 

a training/testing partner, 

please contact us. If you would like to 

have your staff trained on-site, we’d be 

happy to help. 

Specifications Calling 

for LonWorks 

New specifications are coming out with 

LonMark Certification requirements 

for the installers and we wish to support 

this. Keep your eye out for some 

very exciting developments in this area. 

Engineers and owners are turning to 

the LonMark website for qualified individuals 

and the companies they work 

for. Consider this an open invitation to 

support this valuable effort. 

Affiliate Support 

One of the roles of LonMark 

International is to support the 

LonMark affiliate organizations 

around the world. The old adage, 

“Think Globally, Act Locally” has 

never been more appropriate. LMI 

helps define the direction, but we rely 

on the local organizations to carry the 

message. Over the past five months, 

the LMI team has developed a set of

esources and guides to help the local 

affiliates with their marketing, 

technical, educational, and administrative 

goals. The LonMark Affiliate 

Handbook is the result of this extensive 

project to document a wide variety 

of activities that can be initiated at 

the local level and supported by LMI. 

At the time of writing, the second part 

of the handbook is in development 

and will address more administrative 

issues. Copies of the Handbooks 

have been delivered to each affiliate 

around the world and your feedback is 

encouraged. 

Large Project Support 

Occasionally, LMI receives requests to 

support major projects by providing 

specification development guidance, 

master planning coordination, vendor 

and integrator selection, and general 

education on open interoperable systems. 

Over the past two years, LMI 

has been engaged in over a dozen such 

projects and we continue to help with 

ongoing project advice and support. 

Just recently, we have been working 

with several major educational institutions, 

corporations, and industry 

organizations. We welcome inquiries 

and are available for consultation. In 

many cases we refer specifics to qualified 

LonMark member companies, 

another valuable benefit of LonMark 

membership. 

Marketing 

An efficient marketing program has the 

responsibility to engage in a wide variety 

of programs to support our membership. 

We have recently enhanced 

our endorsement, speaking, and promotional 

activities. A complete listing 

of our upcoming events and activities 

is on page 10. 

Technical 

Recently, the LMI Board Technical 

Committee conducted a worldwide 

survey to help define our direction and 

ongoing focus. The response was well 

beyond our expectations and we wish 

to thank the hundreds of people who 


responded. We are compiling the survey 

results and will post a summary on 

our website. 

LonMark Annual Awards 

Program 

We are happy to report that following 

last year’s very successful awards 

program, we are once again searching 

for the best products, projects, 

achievements, and people in the industry 

for this year’s awards program. 

The awards ceremony will take place 

in Chicago on January 27 at 4:30 p.m. 

in conjunction with the AHR Expo 

trade show. For more nominations and 

details see the LonMark International 

website homepage www.lonmark.org. 

As you can tell, we’ve been very 

busy and very productive. We look forward 

to serving you and would love to 

hear your feedback. 

Respectfully, Ron Bernstein

News 

As 2008 draws to a 

close, so does another 

busy – and very 

productive – year for 

LonMark 

We concluded our successful global 

seminar tour, launched our series of 

highly topical fact sheets, which are 

available on our website, and endorsed/ 

sponsored more industry events than 

ever before. The surge in endorsement 

deals is mainly due to our revamped 

non-monetary mutual endorsement 

Think * Integrated * Technology 

agreement, which has proven to be a 

huge hit with event organizers. 

It is straightforward, simple to use, 

and offers both parties enormous benefits: 

we promote the event via email 

blasts, our website, and the LonMark 

magazine, and in return, we request our 

logo to be placed on the event website, a 

speaking opportunity, and a free booth 

and guest passes. Just this quarter, 

LonMark International is endorsing 

nine different events; please see page 10 

for upcoming events. 

At LonMark International, we 

strongly believe in making things as easily 

accessible as possible! Our ‘Affiliate 

Handbook’, which was mentioned in 

the ‘Foreword’, is a prime example of 

easy access to valuable information. 

We are currently working on a similar 

handbook but for our members. The 

handbook will contain a variety of 

educational, promotional, and informational 

activities, all of which will 

help our members to better take advantage 

of all the programs LonMark 

International has to offer.

and EnOcean Alliance 

Enter Strategic 

Partnership Agreement 

to Deliver More Energy 

Efficient Intelligent 

Control Systems 

In an effort to bring new solutions to 

the LonMark community, we are very 

pleased to announce our newly established, 

collaborative agreement with the 

EnOcean Alliance. EnOcean Alliance 

is a consortium of over 60 companies 

working to formalize EnOcean’s self- 

powered, wireless technology as the 

interoperable wireless standard for 

sustainable buildings. 

The partnership, which was entered 

into on September 16, is intended 

to provide a platform for bringing 

LonMark’s open, interoperable devicelevel 

protocol for wired and unwired 

networks together with EnOcean’s RF 

end-device solution for low/no-power 

devices. By leveraging shared marketing 

channels, the two industry-leading 

providers anticipate that the agreement 

will drive new growth opportunities 

for both organizations. 

Wireless devices provide an ideal 

solution in areas where wired devices 

are impractical or too costly to install. 

EnOcean’s unique technology requires 

no battery maintenance and is designed 

to work seamlessly with established, 

interoperable network technologies. 

As such, LonMark-EnOcean interfaces 

have existed in the marketplace 

for some time now. New, cost-effective 

solutions will help deliver even more 

open, interoperable, energy-efficient 

intelligent control systems. 

“The technical, education, and marketing 

teams from both LonMark and 

EnOcean are committed to pursuing 

common, open, interoperable integration 

standards,” said Ron Bernstein, 

Executive Director of LonMark 

International. “We look forward to 

working together as our two organizations 

bring enhanced solutions to the 

market.” 

“The EnOcean Alliance is proud 

to be working in conjunction with 

LonMark International to present 

new interoperable solutions to the market” 

says Graham Martin, EnOcean 

Alliance Chairman and CEO. “We see 

great synergy between our two organizations 

and are excited about the opportunity 

to work together.” 

LonMark offers a significant base 

of over 100 million installed devices, 

well over 700 certified products, an 

existing valuable brand, and worldwide 

support. With EnOcean’s RF 


technology acting as an extension, 

the combined resources of the two organizations 

will address the significant 

needs in the current market, thereby 

providing members from both organizations 

with a unique and reliable set 

of solutions.

Irrigation Problems – 

the Watertight Smart Solutions 

Alarge percentage of water used 

in commercial properties is used 

outdoors for landscape irrigation. 

The US Environmental Protection 

Agency estimates more than 50% 

of commercial irrigation water goes to 

waste due to evaporation, wind, improper 

system design, or overwatering. 

Each of these water waste factors may 

be addressed by working with professional 

irrigation auditors and designers. 

When the sun comes out in the 

morning, any water sprayed on landscape 

plants is lost to evaporation. 

Delivering the water directly to the soil 

prevents this lost water. Converting 

sprinklers to drip, bubblers, or soaker 

hoses where possible will greatly reduce 

losses to evaporation. Areas 

such as shrubs, trees, planters, and 

medians can greatly benefit from the 

conversion. 

Wind carries away mist and diverts 

sprinklers from their targets. Delaying 

sprinklers to run after the wind subsides 

helps guarantee the water hits 

the target areas and doesn’t run off on 

sidewalks and down the storm drain. 

Improper system design includes 

using the wrong emitters for an area 

(sprinklers where drip emitters are 

more appropriate), grouping plants 

with different water requirements in the 

same zone, and applying water faster 


�� 

�� 

�� 

than the soil can absorb. Grouping 

like plants together allows delivering 

the amount of water the plants need. 

If unlike plants are grouped together, 

then water must be applied matching 

the thirstiest plant’s needs leading to 

wasted water or worse yet, root rot 

and dead plants. Scheduling techniques 

such as multiple start times or cycle and 

soak help reduce or eliminate runoff in 

zones where water is applied too fast. 

Overwatering can be eliminated 

using irrigation scheduling based on 

weather or direct soil moisture measurements. 

Using a weather station, evapotranspiration 

(ETo) and rainfall may 

be used to adapt irrigation schedules 

to replace the water used by landscape 

plants. Soil moisture probes directly 

measure water available to plants in 

the soil. When the water level gets low, 

just the right amount may be added 

back. Adding weather-based control 

or direct soil moisture measurements 

can reduce your water consumption by 

20% or more. 

Submetering the water used by the 

irrigation system is also a good way to 

monitor system performance. When 

the water submeter is tied into the irrigation 

scheduling, the water use for 

each zone may be logged. When abnormally 

high water use is detected, the facility 

manager is immediately notified 

that repairs are required via e-mail or 

SMS alert through the controller’s IP 

connection. This allows quick repair 

of mowed off sprinklers and prevents 

significant water waste and damage to 

the landscape from erosion and lack of 

water delivery to the rest of the zone. 

System implementation during the 

initial installation may vary dramatically 

when the landscape matures. This 

can lead to significant problems when 

looking to retrofit an existing landscape 

irrigation system. Wires and pipes may 

already be in place with limited or no 

easy access to adds, moves, or changes. 

By implementing an intelligent control 

and communication platform, costs of 

system changes can be greatly reduced. 

You no longer need to dig new trenches 

through existing landscape to add wires 

back to the controller. Implementing a 

LonWorks based control strategy can 

use an existing pair of irrigation wires 

to expand an existing configuration 

many times over. LonWorks provides 

a great mechanism to distribute the 

sensors and actuators of an irrigation 

control system. 

Using LonWorks over powerline 

(ANSI/CEA 709.3) communications, 

we can add four to eight valves using 

one pair of existing wires. The irrigation 

controller can communicate to 

the new valves using LonTalk ® messages 

and provides an easy upgrade 

and expansion mechanism to new or 

��

existing installations. No need for new 

trenching. 

For example, you have to update an 

existing traditional system because two 

zones were improperly designed. Zone 

2 of this system needs to be subdivided 

into three zones to meet the different 

water needs of the plants. Zone 4 needs 

to be subdivided into two zones due 

to insufficient water pressure to run 

all the sprinklers at once. The existing 

system layout may look something like 

Figure 1. 

Traditional controls require trenching 

back to the controller to add zone 

wires for new Zones 5, 6, and 7 as 

shown in red in Figure 2. 

With a Web/LON enabled controller, 

the existing wiring for Zones 2 and 

4 is used to send LON controls to the 

valve boxes, eliminating trenching back 

to the controller as shown in Figure 3. 

Using LonWorks over powerline 

also provides a convenient method to 

add soil moisture sensors. Properly installed 

soil moisture sensors directly 

measure soil moisture reducing configuration 

errors caused by guesswork 

when determining plant transpiration 

rates. When the soil moisture is below 

the minimum threshold, the controller 

schedules an irrigation cycle to refill 

the soil to the maximum moisture level. 

Direct soil moisture measurement also 

closes the loop. Most irrigation controls 

run open loop or use evapotranspiration 

to estimate soil moisture. Properly 

located soil moisture sensors close the 

loop and provide feedback that water is 

delivered to the target. 

Adding a web interface to the 

LonWorks irrigation controller pro- 

vides remote access 

and diagnostics capabilities 

not found 

in traditional irrigation 

controls. 

Facility managers 

can remotely access 

and maintain multiple 

sites and keep 

�� track of water consumption 

in every 

zone. Landscape 

maintenance crews 

Figure 

can receive instant 

notification of pipe breaks and mowed 

off sprinklers to quickly schedule repairs. 

Access to the web also provides 

a means to connect to online weather 

sources to download forecasts and delay 

irrigation when it’s about to rain. 

Figure 4 is an example system showing 

architecture of the irrigation controller, 

connection to the LonWorks 

powerline network, and irrigation system 

layout. Example zones consist of a 

single soil moisture probe and a zone 

valve. 

Providing local access is important 

too. Landscape maintenance crews require 

a way to turn zones on and off 

�� 

�� 

��

�� 

�� 

�� 

�� 

�� 


�� 

�� 

�� 

�� 

�� 

�� 

to make adjustments and visually inspect 

sprinklers for proper operation. 

The controller should provide an LCD 

user interface and keypad, interface 

for an RF remote, or a way to access 

the web user interface to trigger zones. 

Having a flexible web interface allows 

implementing a cell phone interface for 

access by the landscape maintenance 

crew. If a new landscape maintenance 

company is hired, access for the old 

company can be removed and the new 

company added to maintain the security 

of your system. 

So using a combination of best irrigation 

practices and LonWorks, it 

is possible to achieve significant water 

savings in the commercial landscape. 

The LonWorks approach reduces 

the cost of adding zones and making 

changes when correcting implementation 

problems in an existing installation. 

LonWorks also enables direct soil 

moisture feedback from the irrigation 

zones to provide closed loop control of 

the irrigation system.

LON Technology 

Lights up the Beijing 

Olympic Village 

Energy Conservation a Key Issue 

at “Green Games” 

The Olympic Village in Beijing uses 

LON technology to create an energy 

efficiency lighting control 

system. Lighting typically consumes as 

much as a third of the electricity used 

in a building, making it a prime target 

for energy efficiency at the Olympic 

Village during the Games. The smart 

LonWorks based control system integrates 

all lighting subsystems to optimize 

energy usage while maintaining 

a safe and aesthetically pleasing environment 

for the athletes – contributing 

to the government’s pledge to stage a 

“green Olympics.” 

Beijing committed to reducing energy 

and water consumption per unit 

of GDP by 5% this year as part of a 

push for a ‘recycling economy’ in time 

for the Olympics. 

“Only LonWorks technology was 

able to fulfill the unique needs of this 

project,” said Vincent Wang, General 

Manager, of Lang Meng Technology, 

Inc. “There are a vast number of devices 

scattered across a large area, serving 

the many needs of the Village from 

beautification, to safety, to energy effi- 


ciency. It was extremely 

important to China that 

the Village be seen in a 

positive light by the tens 

of millions of viewers that watched the 

Olympics on television. Because the 

LonWorks products from our various 

suppliers integrate easily, we were able 

to install and configure the project in 

less than two months, helping to ensure 

that the Olympic Village opened 

on schedule.” 

Echelon’s LonWorks control technology 

is incorporated in the Chinese 

national standard for building automation, 

intelligent residential community 

construction, and in the national 

standard for control applications. 

The Olympic Village is the largest 

non-competition venue in Beijing. It 

accommodated over 23,000 athletes 

and team officials during the 2008 

Olympic and Paralympic Games. The 

Village has over 370,000 square meters 

of apartment space, including 22 

six-floor buildings and 20 nine-floor 

buildings, and includes facilities such 

as general information centers, meeting 

rooms, medical clinics, religious 

centers, multiple restaurants, a library, 

parking areas, and entertainment and 

leisure activity centers. 

The smart lighting control system 

integrates lighting subsystems for the 

apartments, public areas, car park areas, 

and all landscape and beautification 

lighting. In addition to increased 

energy efficiency and safety, the system 

is designed to enhance the beauty of 

the Village by illuminating architectural 

details on the buildings and entry 

arches into the Village, as well as various 

landscape features such as water 

fountains. 

“Beijing made substantial, if not 

historic, efforts to produce the first 

‘green Games’ that impact not only the 

Olympic venues, but the entire country,” 

said Anders Axelsson, Echelon’s 

senior vice-president of marketing. 

“The Olympic Village is essentially a 

city within a city and a great example of 

how Echelon and its partners can bring 

solutions that can enhance the quality 

of life in a city while at the same time 

making it more energy efficient.” 

The advanced lighting control 

system was installed by Lang Meng 

Technology, Inc., a technology firm 

providing smart home and lighting 

control solutions based on LonWorks 

technology. 

The solution uses LonWorks enabled 

power controllers and analog input 

modules from Nico Technology 

to control the lighting system, and to 

monitor output status. Echelon’s LNS ® 

network management software was 

used to design and install the network, 

and Echelon’s i.LON ® Internet Servers 

automatically turn lights on or off 

based on pre-programmed scheduling 

functions. The i.LON servers interface 

with Advantech Industrial Automation 

Group’s WebAccess HMI, which can 

be used to monitor and control the 

system from the property management 

center.

LonWorks Delivers Energy Savings 

to Sweden’s Post Office Headquarters 

The Swedish Post Office, Posten, 

which is one of Sweden’s largest 

corporations, provides postal 

services to four and half million homes 

and 900,000 businesses daily. Employing 

more than 30,000 employees, the 

Swedish Post Office underwent considerable 

changes during the late nineties. 

A key part of this process included the 

concentration of the organization in a 

new head office. 

Posten was looking for a building 

to serve as the shaping force for 

future operations in an environment 

designed to stimulate communication 

and creativity. Eight architectural firms 

were invited to compete to design the 

headquarters in Solna in Stockholm, 

Sweden. BSK Architects won the competition 

with a design for a building 

that preserved the landscape by following 

the natural terrain. The building is 

known as the “Thinktank” because of 

the series of small protruding rooms 

in the glass façade, the “think boxes”, 

which are lit up at night. An intervening 

atrium separates two parallel office 

floor plates which are joined by footbridges 

and cocoons (secluded meeting 

rooms for up to 10 people). 

More than 1000 people work in the 

building, which has a total floor area 

of 58,000 square meters. There are 


1100 workstations on 

six floors providing a 

total of 25,000 square 

meters of open plan offices 

and the building 

also has parking for 

450 cars. The project 

cost approximately SEK 

800 million (EUR 84 

million - US$ 135 million). 

It also includes a 

gym, a swimming pool, 

and several shops and 

restaurants. 

The building is completely 

glazed from floor to roof with 

10,200 square meters of glass, which 

provides an ideal opportunity to save 

energy by dimming the lights depending 

on the level of the daylight. The 

overall open office plan inspired many 

energy saving solutions and gave the opportunity 

to make the building “alive” 

during darkness by illuminating coloured 

walls inside. Systems integrator, 

Energo, was given overall responsibility 

for both design and programming 

of the building automation systems. 

Challenges 

Posten wanted a networked solution 

using LonWorks technology giving 

the possibility for cooperation between 

different subsystems 

such as the lighting 

system, alarm handling, 

HVAC, sun 

shading, and scheduling. 

The most interesting 

part was the 

energy saving possibilities 

for the open 

plan office area. This 

included the use of 

movement detection 

for both lighting and 

HVAC and daylight 

dependent illumination. 

The goal was 

to use as few on/off light switches as 

possible because of the wear and tear 

on the fluorescent lamps and to decrease 

the number of lamp changes 

necessary. 

Solution 

LonWorks technology was used 

to provide a complex lighting solution. 

At 7:00 a.m. the lights come on, 

brightening from 10% to 100%. At 

the same time, the movement detectors 

are turned off and the light sensors 

are turned on. During daytime 

the zones closest to the windows are 

daylight dependent, meaning that they 

dim or brighten based on the amount 

of natural light coming into the offices 

to provide a constant light level that is 

comfortable for the staff as well as energy 

efficient. At 7:00 p.m. the lights 

turn off, dimming to 10%. At the same 

time, the movement detectors are activated 

and the light sensors are deactivated. 

During night time, movement 

detectors turn on the lights in zones 

that are occupied. The lights remain 

on for an hour and then, if no one is 

present, dim down to 10% again. 

All conference rooms have movement 

detectors for air handling and 

also turn off the lights if the room 

has been empty for 30 minutes. Most 

importantly, once the light has been

turned off it is necessary to 

manually switch on the light. 

This saves additional energy 

since the light does not turn on 

if someone just quickly enters 

the room. 

Being familiar with 

LonWorks as a tool, Energo 

was confident with the way it 

works. Its open architecture allows 

devices from multiple manufacturers 

to be incorporated into one unified 

system for better control and efficiency. 

Some 3000 nodes were used, including 

LonMark certified Tridonic FTT- 

TLS and Capelon/CeTeLab Focus 1575 

movement detectors. Other products 

incorporated were from Somfy as well 

as Time2Lon, Lexel/Gira push buttons, 

Liwo nanonode and Compwell 

AM2002-3106. 

Benefits 

The building contains 4100 luminaries 

and therefore any change in brightening 

or dimming the lights generates 

large savings. During the light times of

the year the brightening of the lights is 

changed from 7:00 a.m. to 7:30 a.m. 

and the dimming time is changed from 

7:00 p.m. to 5:00 p.m. due to Posten’s 

shorter summer working hours. The 

movement detectors brighten the lights 

in occupied rooms if anyone works 

later than 5:00 p.m. These alternating 

brightening and dimming times provide 

energy savings of up to 14%. 

The daylight dimming function 

generates savings that vary at different 

times of the year, especially so in 

the Nordic countries. Just changing the 

lighting level to 10% for as little as two 

hours a day makes a saving of 31,000 

kWh per year. This translates into huge 

Representing Manufactured Products by 

energy bill savings, especially with today’s 

increasing energy prices. 

The solution was created with a 

minimum of on/off switching, which 

increases the service life of the fluorescent 

lamps. The combination of a 

daylight-dependent office lighting system 

for the daytime and movement 

detection lighting during the night 

provides better lighting conditions 

for the staff as well as greater control 

over energy consumption. Fewer spare 

parts will be required due to the use of 

the same movement detectors for both 

lighting and HVAC. Furthermore, the 

lighting scheme has made the Posten 

Headquarters building a landmark in 

Sweden.

Hannah Montana Stage 

on the set, everyone……” 

the director an- 

“Quiet 

nounces. A second later, 

one loud ring of the bell, red light beacons 

flash outside the stage doors, huge 

cooling fans slow to a silent speed, 

“Rolling, and…… Action!” shouts the 

director on the stage of the Hannah 

Montana show in Hollywood, California. 

The actors perform the sketch 

they’ve rehearsed all week and the 

studio audience laughs after each gag. 

When the director shouts “Cut!”, the 

bell rings twice, red light beacons become 

dark, and the supply fans ramp 

up to pump 140 tons of chilled air full 

speed onto the stage. 

Traditional red light controls used 

in movie making are comprised of 

hardwired relay logic based systems. 

As performance sets are reconfigured, 

the controls often require re-wiring 

and are difficult to integrate with the 

mechanical systems that cool the stage. 

At Tribune Studios in Hollywood, 

California, a new red light control system 

has been deployed based on open/ 

interoperable LonWorks network 

technology that includes LonMark 

certified control devices from four 

different manufacturers – Hubbell, 

Echelon, Yaskawa, and Functional 

Devices. Each device provides specific 

red light system control functionality 

and communication over a free-topology 

link power LP-10 twisted pair media 

channel. 

When the sound engineer receives 

instruction from the director that the 


performance scene is about to commence, 

he presses one of three buttons 

on a hand-held Hubbell control pendant 

which then transmits a network 

variable message to a smart relay device 

made by Functional Devices that 

rings the ‘Ready’ bell once. A second 

‘Red Light’ button on the pendant 

sends a network variable to additional 

Functional Devices wired to red light 

beacons outside stage entrances. The 

same network variable is received by 

an Echelon Lonpoint device which 

initiates a fan speed network variable 

sent to Yaskawa variable speed drives 

on four chilled water air handlers high 

above the stage floor. When the third 

‘All Clear’ button is pressed, a network 

variable is sent onto the network, 

which rings the bell twice, shuts off the 

red-light beacons, and ramps the air 

handler fans up to a configurable speed 

level. 

An i.LON100 internet server provides 

for web browser based monitoring 

and control of the system from 

the studio maintenance offices. Fan 

speeds during and after filming are easily 

adjusted through the web interface 

according to comfort and sound requirements. 

Additionally, maintenance 

technicians can quickly schedule cooling 

system operation as well as shut 

down operations when the performance 

wraps. 

Prior to automation, the state of the 

HVAC plant on stage 5 was such that 

it had either a 100% on or 0%, with 

no load or demand control, and obvi- 

ously drawing much more power than 

required. Since implementation of the 

automation system, the plant is cycling 

on demand, cutting power consumption 

(based on on/off time of the compressors) 

by as much as 50%. 

Service calls in order to address temperature 

related discomfort have been 

reduced dramatically, as any issues can 

now be handled directly from a work 

station. 

All the electrical gear, as well as the 

switch gear that controls the stage air 

conditioning, which historically has 

had some heat problems due to overloading 

or inefficient consumption, is 

now in excellent shape. 

Albert Blondeel-Timmerman is the 

electrical foreman for Tribune Studios 

who specified an intelligent red light 

control system during construction of 

the Hannah Montana set. “Since production 

companies come and go often 

here at Tribune, we wanted a system 

that could be easily reconfigured withoutwiringchanges”Albertcommented. 

“Plus, we wanted a control system that 

provided low speed air conditioning 

during performances without creating 

noise issues. An added benefit was the 

remote user interface that allows us to 

monitor stage conditions and quickly 

respond to client requests.” 

“Our operating costs have risen 

steadily in the past few years,” continues 

Albert, “mostly due to rising rates 

and 24-7 operations, so there is no 

documentation we can provide which 

clearly illustrates the effect on our utility 

bills. But from 30 years experience, 

I can tell you that our retrofit program 

with high efficiency lights, and now 

our automation program have been the 

biggest factors in controlling costs and 

improving client service. Since implementation 

of the automation system, 

the plant is cycling on demand, cutting 

power consumption (based on on/off 

time of the compressors) by as much 

as 50%! In addition, we have virtually 

NO temperature related service calls 

on a stage where we used to have 4 or 5

every shoot day! We have also been able 

to use the stage’s demand control plant 

to supplement the aging units on stage 

4 (which were always insufficient for 

the load). This has helped us to avoid 

the expense of replacement of and additions 

to those units. We have also 

saved on labor by being able to effectively 

troubleshoot the units remotely 

from the graphic computer interface, 

so when we go to the rooftop, we already 

have materials and tools required 

to effect repairs. 

“In building 21, we took existing 

units and transformed them into as 

close to a true multi-zone system as you 

can get with a DX system. This avoided 

the cost of installing individual units 

for post production space, which, at 

about US$10K per incident times 20 

spaces, would have been cost prohibitive. 

We have essentially created a load 

sharing condition that allows us to get 

the maximum efficiency while maintaining 

client comfort and protecting 

valuable technical equipment. With the 

Benefit from our wireless, battery-less solution 

• Support for a wide variety of wireless, battery-less sensors and switches, 

such as temperature sensors with setpoint and fan speed command, light 

switches & window contacts 

• Integrate up to 6 wireless devices with one controller 

• Eliminate external wiring and reduce retrofit expenses

High-Tech behind a Traditional Front 

– Room Operating Panels by Thermokon 

in the Hotel Savoyen in Vienna 

Alexander Herdlicka (Thermokon Austria), 

Mircea Cojocea (Hotel Savoyen) and 

Johann Steiner (Johnson Controls) during 

an on-site appointment 


An impressive combination of 

classic and modern design characterizes 

the new Austria Trend 

Hotels Savoyen Vienna located on the 

edge of the wonderful Belvedere palace 

park in the middle of the embassy 

quarter of Vienna, Austria. The former 

building of the Austrian State Printing 

Trade, built in 1888 and 1892 according 

to the plans of Heinrich Köchlin, 

was fully rebuilt from 2006 to 2007 according 

to the construction plans of the 

famous architect, Prof. Dipl-Ing. Hofmann. 

The hotel integrates a part of 

the precious historical façade from the 

year 1892, and creates an architectonic 

bond between past and future. On 

the outside, the building has saved its 

historical face. Inside, however, a very 

modern hotel has been created. 

319 fashionably designed rooms, including 

43 individually designed suites, 

win over guests with their classic modern 

architecture and sophisticated design. 

The heart of the building is the 

atrium which is flooded with light and 

spreads over six floors. It is the starting 

point of all the important areas of 

the hotel such as the ballroom, which 

is more than 1000 square meters, the 

seven variable seminar and conference 

rooms that range between 25 and 150 

square meters, the atrium lounge, fitness, 

and wellness area as well as the

hotel rooms. The bright conference 

rooms are equipped with the latest 

technology and offer the best conditions 

for all kinds of events. 

To meet the requirements of a 

four-star-plus hotel, the sophisticated 

room operating panel WRF08 by 

Thermokon Sensortechnik with illuminated 

display for air conditioning, 

lighting and shutter control was selected. 

“Parameterization and design 

were decisive in choosing the WRF08,” 

confirmed the project manager, 

Reinhard Idinger of Johnson Controls. 

All WRF08 room panels communicate 

via the LON field bus with the AD- 

IRS 1035 modules, the AD-IRC 4245 

control system of Johnson Controls, 

and the building control technology. 

The free topology selection of the LON 

network corresponded best to the architectural 

structures. Moreover, LON 

enables later extensions without having 

to pay any heed to the existing bus 

topology. 

Benefit from our wireless, battery-less solution 

• Support for a wide variety of wireless, battery-less light switches and 

sensors, such as temperature sensors with setpoint and override, 

humidity sensors 

• Eliminate external wiring and reduce retrofit expenses 


Innovation Revealed 

Enhance new and retrofit projects with Distech Controls’ state-of-the-art VAV Controllers. 

VAV Controller 

Smart Sensor 

The bus system networks almost 

400 room operating panels and 14,000 

data points. All system statuses are visualized 

on the building control technology. 

The visualization is realized by the 

Metasys Operator Workstation (OWS) 

and Metasys M5 Facility Operator on a 

project PC. Even the room-reservation 

computer is connected to the building 

automation and shows the current occupancy 

status each day. Unoccupied 

rooms remain in a stand-by mode while 

in occupied rooms the room temperature 

is kept at night temperature (night 

lowering) as long as the guest is not in 

the room. As soon as the guests check 

in and the key card reader is activated, 

the heating is changed to standard operation. 

Thus, energy is saved and running 

costs are reduced. 

“It is too early to make a summary 

of the energy savings after only nine 

months, but experience has shown 

that all the results are positive. The 

operation is very easy and the build-

Link Power Technology: 

Extending its Reach to More Devices 

Sensor networks are rapidly becoming 

normal extensions of 

control networks. To some, a 

sensor network is synonymous with 

a control network; to others, a sensor 

network is an RF mesh network. However, 

sensor networks can be restricted 

to only sensing or performing control 

functions, and they can be either wired 

or RF-based. None of these distinctions 

really matter. What does matter is: 

� Does the sensor network perform its 

assigned task? 

� Is it economical to install? 

� Does it perform better than a nonnetworked 

set of I/O? 

� Can it be easily attached to a control 

network? If so, does it “disappear” 

into the management of that 

control network or does it add a 

layer of complexity and cost? 

� Does it provide performance, maintenance 

or other field benefits? 

In many cases, the right form of a sensor 

networking technology is, in fact, a 

control network – one that’s engineered 

to compete on a cost basis with sensor 

networks, yet provide most of the benefits 

of a control network. For many 

applications in many markets, such a 

network would provide the following 

technical and market benefits: 

� 

� 

� 

� 

� 

Low cost, system-on-chip design 

Reduced material costs by using 

the same cables for both power and 

control 

Fast and easy installation using a 

self-installation feature that requires 

no special tools 

High-speed response times 

“Invisible” integration with more 

sophisticated control networks 

While all of these attributes are desirable 

in a control network, they’re essential 

to many applications for sensor 

networks. 

So in the final analysis, the question 

is not about a sensor or an RF mesh 


network; it’s about choosing the right 

networking technology to deliver a 

material, quantifiable, and sustainable 

set of benefits to users, manufacturers, 

and integrators. 

Introduction to Pyxos 

The Pyxos platform extends the power 

of LonWorks control networks to the 

smaller and less expensive devices like 

low-end switches, thermostats and other 

sensors. The Pyxos platform is the 

only sensor networking solution designed 

to be part of a complete control 

ecosystem. Because Pyxos networks 

work seamlessly with LonWorks control 

networks, manufacturers can easily 

connect their products to existing 

automation applications for remote 

monitoring and control. Together, 

LonWorks and Pyxos networks create 

a synergistic system, with LonWorks 

networks providing the ultra-reliable 

backbone for any number of Pyxos 

based devices and sensor networks. 

Built upon tiny, low-cost Pyxos FT 

chips, the technology automatically 

configures itself – without special tools 

or skilled labor – into a high-speed 

control network. 

What is Link Power? 

Low-voltage sensors and small actuators 

are often located in hard-to-reach 

places, making them inaccessible to a 

local power supply. Even when accessible, 

the use of separate power and 

control wires creates an extra burden 

for installation and maintenance, resulting 

in increased failure rates, and 

in turn, increased overall system costs. 

Echelon’s Link Power for Pyxos networks 

lets you send power over the 

same pair of wires used for monitoring 

and control, thus reducing material, 

assembly, and maintenance costs. 

Pyxos networks support two types 

of Link Power: the existing Standard 

Link Power and our new High-Power 

Link Power. Which type you use depends 

on the maximum power consumed 

by any node in your Pyxos 

network. 

StandardLinkPowersupportsabout 

0.5W of power per node – enough to 

power simple thermostats and switches, 

but not enough for devices that include 

a display, a small motor, or any sensor/ 

actuator that uses more than 0.5W of 

power. For those building automation 

devices and other devices with greater 

power needs, there’s High-Power Link 

Power.

the same cable in an orthogonal way 

such that it can scale more easily than 

Standard Pyxos Link Power. Although 

High-Power Link Power requires a 

three-wire cable for the network, it 

doesn’t have to be data-grade; Standard 

Link Power requires a data-grade, twowire 

twisted cable. Thus, using High- 

Power Link Power can help reduce 

your overall system costs. Both Link 

Power techniques use the same Pyxos 

chip in their designs. The difference 

lies in the way the circuit around the 

chip is built. Several other benefits of 

High-Power Link Power over Standard 

Link Power networks are shown in the 

chart on page 24. 

Applications 

Indoor/outdoor LED lighting. Adding 

control networking technology to LED 

lighting systems lets you exploit the 

true power of LED lights. For example, 

adding controls to LED lighting lets 

you easily change the color and intensity 

of light emitted from a single lighting 

fixture. Since LED lights use as much 

as 90% less energy than incandescent

bulbs with the same lumen output, you 

can control and power them on the 

same cable with Pyxos High-Power 

Link Power. Most LED lights use 3W- 

20W per light, based on application. 

While accent, landscape and retail display 

lights consume 3W-7W per node, 

general illumination LEDs lights consume 

20-25W per light. 

Security cameras 

Sensors, switches, and actuators in 

building automation systems. In most 

buildings, these devices are controlled 

by hard-wired 0-10V or 4-20mA analog 

signals. Extend your networking 

reach while powering these devices on 

the networking cable itself. Use Pyxos 

High-Power Link Power to power and 

control not only switches and thermostats, 

but also LED lights, blinds, and 

small VAV actuators. Other features of 

Pyxos technology, which are critical for 

some sensor/actuator networks, include 

two-way communication that allows 

proactive service for failing devices and 

polarity-insensitive wiring that reduces 

the installation and maintenance cost 

of the system. The figure below shows 

a commercial lighting system architecture 

using Pyxos High-Power Link 

Power technology to power, monitor 

and control switches, occupancy sensors 

and LED lights – all over the same 

cable. 

Most security cameras have separate 

cables to power the camera and control 

pan/tilt/zoom operations. Also, 

most cameras are installed in locations 

far from a power source. With Pyxos 

High-Power Link Power, you can combine 

power and control on the same

cable, greatly reducing material and 

installation costs. 

The devices described in the applications 

above can be integrated into 

LonWorks networks, creating a unified 

building/centralized system for remote 

or local monitoring and control. 

Reference Design 

The Pyxos High-Power Link Power 

technology is available as a royaltyfree 

reference design from Echelon. 

It provides a fast time-to-market approach 

for application development, 

letting you go from concept to product 

in just a few weeks. It includes schematics, 

lost-cost BOM, and details on 

a 12VAC version of the High-Power 

Link Power design, and can be modified 

to work for either AC or DC, as 

well as other voltage levels. The highly 

modular design allows for a constant 

voltage or a constant current version 

of the driver for the load, and includes 

optional Power Factor Correction to 

extend the distance of the network. 

For even faster development, the reference 

design includes the Pyxos Point 

and Pilot API and drivers for the microcontrollers 

used. 

Conclusion 

Many of the end devices connected to 

LonWorks network controllers can be 

low or high power - they can now be 

powered and networked over a single 

cable with the use of Pyxos High- 

Power Link Power technology.

Sea: the fashionable southeast coast 

of Turkey. 

This recently opened hotel has 

been designed by a world famous 

international interior designer, 

with the intention to reflect the famous 

characteristics of the historically 

rich country of Turkey. It has 

been constructed by Turkey’s Zafer 

Construction Company: around 

2500 workers and engineers took 

part in the construction. 

Turkey is known for its impressive 

heritage and traditions, and 

Mardan Palace will stand out as an 

exquisite and true five star resort, 

combining rich culture with traditional 

architecture and modern amenities 

– a luxurious environment where 

guests can choose how to divide their 

time between sun, spa, and culture. 

Rooms: the hotel is comprised of 560 

rooms and suites: 70% of all rooms are 

60-70 square meters. Standard rooms 

are around 50 square meters and double 

bedrooms are around 200 square 

meters. In addition, there are 20 villas 

(each around 100 square meters) and

The Challenge: Comfort 

and Technology in each 

Room 

In each room, this new 5++ star hotel 

offers guests an advanced interactive 

multi-media system (flat screen LCD 

TVs, internet access) and also a comprehensive 

automatic control system 

for their comfort, allowing a flexible 

local command through a customized 

“multi-jobs” remote controller (lighting 

and HVAC functions). 

Attractive design and command 

reliability were required. No technical 

equipment is visible in the room in order 

to respect the high level of palace 

aesthetics. Radio frequency technology 

was consequently selected: the radio 

25

26 


receivers are installed in a technical 

cabinet along with a LonWorks interface 

in each room. 

On the other hand, LonWorks was 

selected as the best technology to provide 

open and interoperable solutions 

which allow the use of other LON 

equipment for comfort control functions 

(lighting, climate, etc.). 

The LonWorks 

Solution & Key Benefits 

The Dalilon ® RF remote control system 

with the LonWorks Dalilon interface 

combines a smart design and easy 

intuitive operating. 

Each guest command is translated 

by the Dalilon interface into a “SNVT” 

standard variable which is then sent 

onto the network to drive the associated 

comfort devices (lights, HVAC 

unit etc.). 

The radio remote controllers are 

imprinted with the brand of the hotel 

and all keypads are customized for in- 

tuitive use. 

� Temperature setting is controlled 

by two dedicated buttons 

(temperature up/down). 

� Fan speed is controlled by a 

single dedicated button 

(1-2-3, slow-medium-fast). 

� The main lighting circuit is 

controlled by two dedicated buttons 

(dim up/ dim down). 

� Two single buttons allow turn-off of 

the main lighting circuit, or turn-off 

of the WC lights. 

� A&B buttons allow selection of 

lighting predefined scenarios.

Unified System Architecture 

How specifying an open building 

automation system reduces 

costs and increases flexibility. 

Having a specification that allows 

for any system option and protocol 

leads to a more complex system, one 

that is more cumbersome to install, 

commission, and maintain. It can be 

compared to allowing all employees in 

a company to use PCs, Macs, UNIX, 

and Linux computers, while also allowing 

Ethernet, ARCNET, and Token 

Ring as network communications media, 

and insisting that the IT department 

maintain and service all of these. 

The workload becomes unbearable, 

which is typically why IT departments 

pick one platform and stick with it. 

Likewise, it is typically recommended 

to choose one common protocol 

for the entire building control 

system infrastructure and stick with it. 

The costs go down and the maintainability 

goes up. If there is a specific 

application or sub-system component 

that is not available on this standard 

protocol or if there is a specific need for 

using an alternative, this should be justified 

and a gateway (protocol translator) 

identified and specified. However, 

this should be the exception, not the 

norm. 

Defining a common system architecture 

using standard, open methods 

is important and more appropriate than 

specifying the “buffet” style that allows 

anything to be used. An open building 

automation system provides interoperability 

where software and hardware 

from multiple vendors can communicate 

and coexist without the use of protocol 

converters and gateways. There 

are a variety of open protocols on the 

market including an interoperable protocol 

from LonMark International. 

LonMark is a non-profit association 

with over 600 member companies who 

are manufacturers, designers, and system 

integrators, as well as end users 

committed to the development, manufacture, 

and use of open, interoperable 

LON products and networks. 

A good open building automation 

system specification will define the requirements 

for each aspect of the system. 

When defining an open spec, it 

is important to bear in mind that it is 

more than just the protocol that needs 

to be specified. There are five elements 

that need to be defined: 

1. 

2. 

3. 

The Infrastructure – Including the 

protocol, routers, media type, IT 

connectivity, etc. All these should 

be specified based upon open 

standards, not on one vendor’s 

specific product. A single system 

infrastructure provides the benefits 

of a reduction in construction 

costs, longer life cycle, and lower 

maintenance costs as well as an 

improvement in performance for 

the whole building. 

The Devices – These are the controllers 

in the network that produce, 

consume, or manipulate data 

and control/monitor the system. 

In an open system, it is possible 

to use devices from different vendors, 

because they all conform to 

a uniform industry standard, such 

as LonMark. This means that the 

system is not locked into a single 

supplier, allowing the best and 

most cost-effective equipment to 

be used. In this way, suppliers are 

able to concentrate on developing 

products, which focus on their core 

competency and not have to develop 

a complete system. Conversely, 

an integrator who is capable of 

working with the open protocol 

will be able to install a complete 

system selecting the most suitable 

products from different suppliers. 

This way, only one integrator is required 

for the entire system instead 

of multiple integrators, which can 

be expensive and cause isolation 

of the subsystems. An open system 

also makes upgrading easier and 

more flexible. 

The Tools – These are the software 

or network management tools that

4. 

configure, commission, and maintain 

the system. The tools on the 

system need to be able to co-exist. 

Device configuration plug-ins 

(modules) have been developed to 

allow use of any standard network 

management tool. This allows 

vendors to configure their devices 

with an open tool, meaning users 

are free to use tools from any vendor 

they choose. 

Graphical User Interfaces – These 

are typically the visualization tools 

that the user or controls manager 

uses to obtain a view into the system. 

User interfaces allow control, 

monitoring, reporting, alarming, 

scheduling, and diagnostics. An 

operator workstation (user interface) 

affords the means to efficiently 

and effectively manage 

operations as well as display and 

manipulate a graphical representation 

of the control network. A user 

interface provides the same look

and feel for monitoring and control, 

regardless of which vendor’s 

system or subsystem an operator is 

viewing. As a result, system operators 

need only become proficient 

with one user interface. 

Enterprise Connectivity – The 

method for connecting the building 

control network into the data 

network – is known as the LON- 

LAN-WAN architecture. This ensures 

that the control system becomes 

an element of all the data 

sources available to the enterprise. 

Open interfaces have been developed 

to ensure that data communication 

between the LON (the 

building control network) and 

LAN (Local Area Network) is accessible 

by any vendor. To provide 

this connectivity, enterprise level 

infrastructure devices are needed, 

and they must be specified as open. 

Standard routers are used, which 

means no gateways are required.

Given this summary, it is strongly 

suggested to limit the main system 

specification to just one methodology 

for communication. To ensure a truly 

open system, all five systems elements 

must be open. This means each element 

must be interoperable and all training 

and servicing must be specified as 

open, in other words, not locked into 

one system service provider. This, of 

course, is assuming there is a desire to 

reduce costs, improve flexibility and 

choice of products, provide the option 

for choosing the best system integrator, 

and allow for open bidding on both the 

initial installation and the long-term 

service contract. For more information

Intelligent Buildings and Homes – 

How to Choose the Right LON Integrator? 

The two concepts “Intelligent 

Building” and “Smart Home” 

are widely known today. In the 

past, very few houses were equipped 

with intelligent monitoring and control 

systems from the start; however, more 

often than not, even in new buildings, 

such systems are installed at a 

later date. How should the user decide 

whether he needs an intelligent home 

and if he does, how intelligent should 

it be? Do the complex solutions from 

the world’s leading manufacturers fit 

every need? Is it wrong to rely on prefabricated, 

“off the shelf” solutions for 

complex projects? Building automation 

is a multifaceted service and that 

means not everything depends on the 

equipment and system supplier, but 

rather on the integrator – the one who 

installs the equipment and the system. 

What criteria should be used in choosing 

a LON integrator who can be trusted 

with such an extensive project as an 

intelligent building? 

There are a range of services offered 

in the field of building automation on 

a system integrator’s website. There is 

probably also a list of completed refer- 


ence projects and high-end clients. In 

fact, a large amount of information is 

supplied here, but it is seldom well presented: 

photos show a general view of 

the building, the interior design, even 

some switches and maybe the operating 

panel, but this hardly explains how 

this specific LON system functions and 

whether the system provides any added 

comfort and security or uses resources 

efficiently. 

When choosing an integrator, what 

sort of criteria should be used? The 

company’s number of years of experience 

working in this field? The long list 

of references and clients? However, all 

projects are not the same. They vary in 

the degree of complexity and quality, 

ranging from the client’s needs to the 

type of structure. In order to correctly 

evaluate a project, one must know, 

apart from the necessary area specifications 

such as the number of floors 

and function of the building, the extent 

of the subsystems and the degree of 

their automation and integration. It is, 

therefore, difficult and sometimes impossible 

for a person, such as the building 

owner, to be able to sift through all

Table 1: Classification of systems according to their integration level 

the marketing babble to find the information 

needed to make an educated 

decision about which intelligent control 

system to install and which integrator 

should do the job. It would be helpful 

to have a detailed list of integrators 

on hand, which has been put together 

by experts based on clear and explicit 

criteria. A basis for this list could be 

an assessment of the completed LON 

projects from the portfolio according 

to a particular classification table (see 

table 1). 

The classification table contains five 

complexity levels, similar to the fivestar 

rating system for hotels. Here is an 

explanation of some of the parameters 

used for defining the classifications: 

1. The number of data points (I/O) is 

easy to estimate. The more devices 

there are, the more complex the 

project is. 

2. In an automation network every 

subsystem should be well defined 

and should combine different applications 

and functionalities using 

the correct devices. 

3. Currently three protocols are acknowledged 

as open standards for 

building and home automation: 

LON, BACnet, and KNX. 

4. For visualization at least 50% of 

the data points in the network need 

to be compatible. 

5. For total management every software 

and hardware solution can be 

used for at least 50% of the data 

points. 

6. Web-services and remote access 

via the Internet is accessible for at 

least 30% of the data points. 

7. For projects of the highest category 

implementation of not less than 

10% of the devices must come 

from different providers. 

8. The more subsystems there are, the 

more complex the project is.

9. 

10. 

Different subsystems are not only supposed to be automated 

and combined into one network, but also work 

together using the same algorithms. 

For complex projects it is necessary to be able to directly 

use the information provided by the management system 

for important business processes and decisions. 

Using a classification table like this could help the customer 

correctly evaluate future projects. Of course, a customer 

will look for a systems integrator who has experience with 

similar projects. When categorizing the integrator and the 

company, he can only reach a specific level if the systems 

installed portfolio contains at least one reference project 

that contains all the parameters of that particular level. A 

list of companies that work with LON technology based on 

such a classification table would be very convenient for customers 

to have. Because integrators continuously upgrade 

their qualifications, the list should be updated regularly and 

should also be generally accessible. Information about the 

LON companies should be published only after receiving 

their approval. 

Before acceptance of the list it should be discussed and, if 

necessary, changed, taking into account the opinion of LON 

experts. After approval and publication, this document can 

also be used as a basis for other classifications and normative 

documents.

Editor’s Note 

Mr. Pasekov has set forth an excellent approach towards 

defining a qualified integration company. LonMark 

International’s Professional Certification Program is the 

first phase of a program to establish levels of competency 

in the controls market. Now that over 250 professionals 

have been certified, development of a set of criteria for 

integration company proficiency is planned. We invite your 

comments and feedback. Look for an announcement 

regarding the creation of a working group within LMI to 

begin the formal definition process.

“Demand Response” – 

A new challenge for LonMark 

Response” (DR) refers to a set of strategies 

which can be used in competitive electricity 

“Demand 

markets to increase the participation of the demand-side, 

or end-use customers, in setting the process and 

clearing the market. In other words, DR means that the enduser 

voluntarily sheds load during a limited timeframe. 

Power outages in the USA, 

wind energy networks in Europe 

Shortly after the turn of the 21st century, the US experienced 

huge power outages, which were largely caused by overload. 

As an emergency first measure, end-users were encouraged 

to shed loads as quickly as possible. 

This has led to short-term stabilization of the power grids. 

As a result, universities and innovative companies (such 

as the Lawrence Berkeley Lab in California, Constellation 

Energy and EnerNOC) have developed commercial models 

(Economic DR). The redistribution of energy, potential 

savings, and financial gains achieved on the open electricity 

market are impressive. 

This was how EnerNOC passed on their 2007 earnings 

of US$65 million to the “Emergency” and US$42 million 

to the Economic Program in Pennsylvania [1]. The proceeds 

will be acquired by the electricity exchanges (see Figure 1), 

Figure 1 

who will buy energy on the deregulated electricity market 

and then resell it to their end-users. The potential savings 

are comparable to the capacity of a nuclear power plant. 

In Europe, the situation is somewhat different; a simplified 

“Demand Response” has been available for several 

years. Looking at the solutions for the 21st century, one 

must mention static “Demand Response”. These are mainly 

fixed time profiles for storage heaters, hot water processing, 

and heat pumps. 


The extensive use of wind energy in northern Europe 

means that the grid operators now face new problems [2, 3, 

5]. The regular 24-hour wind energy forecast can vary up to 

10% from the actual weather forecast, which can seriously 

disrupt the allocated reserves. 

Politically, Europe has more or less decided to phase 

out nuclear energy and to replace it with renewable energy 

sources. Long-term, in Europe, we cannot get by without an 

excellent “Demand Response” infrastructure. 

How does “Demand Response” 

function technically? 

The Berkeley Institute is one of the leading research facilities 

within energy supply distribution based on renewable 

energy [6]. The Berkeley installations are described in the 

technical schematics (Figure 2). 

Figure 2 

Via the “Standard Utility interface” (SUI), the “Demand 

Response Server” (DRAS) receives offers from suppliers over 

the Internet. Prognoses are generated on the server based on 

weather and wind data over the next couple of hours, and 

energy is bought and sold accordingly. The software works 

the same way as the management of a hedge fund in the financial 

market. On the consumer side, it communicates over 

the SPI with each end user installation. The data contains information 

relating to the amount of energy, costs, and time 

limitations [7]. 

On the consumer side the summarized information of the 

DR telegram is transferred to a device or an entire building. 

After determining the energy needs, the consumers can then 

accept or reject the offer. In case of “Emergency Demand 

Response” the consumer has to follow the command. 

Figure shows an example of a tariff increase of two levels, 

which motivates the consumer to reduce their consumption 

by 1.3 MW. The graphic shows the power consump-

noon time, the tariff increases by two steps (12:00, 15:00). 

The line “OAT BL” shows the average regional temperature 

gradient. The energy consumption caused by air conditioners 

tends to follow this temperature curve. The line “CPP 

BL” (Critical Peak Pricing) shows the price history of critical 

peak loads. The graphic clearly shows how the energy consumption 

can be controlled through pricing. In a further automated 

attempt in 2007 [8] the Berkeley Institute compared 

more pricing options. 

Importance for LonMark 

The American network operators require building operators 

to expand their automation systems to support “Demand 

Response”. Such building management systems must be 

enabled to reduce the energy consumption to, for example, 

80% upon command. This requirement may look different 

depending on the building zone and may have to be accordingly 

configured by the facility managers. 

The family home also offers an enormous potential for 

temporary reduction of energy consumption. At present one

Megawatt reduction 

during high price period 


counts a time window for refrigerators of +/- 4 hours, for 

washing machines also +/- 24 hours. This means ultimately 

that individual devices have to react upon the “Demand 

Response” requirements. LonMark is the technology 

which is spread worldwide in buildings as well as in utilities 

and metering companies. This is why LON technology 

is predestined to define a scalable interoperable solution for 

consumers. 

The DR application is also interesting for the rapidly 

growing market of LON based streetlighting. On the energy 

production side the solutions are IP based (SOAP XML, IEC 

61850), as the utilities already have an efficient infrastructure. 

An open communication solution on the scale required 

cannot be limited to individual standards. This also applies 

to LonMark in that joint solutions with similar standards 

should be sought in order to have a widespread impact. 

Implementation by LonMark 

The technical committee of the LonMark International 

Board has launched a program together with the Utility Task 

Group which will systematically lead to a targeted solution. 

The group is working with the team from the Lawrence 

Berkeley Institute in California as well as manufacturers, 

network operators and end users. At a European level, they 

are seeking cooperation with universities, technical schools 

and local LonMark Affiliates to define a solution which can 

be implemented worldwide. Members and interested institutions 

are invited to actively participate in this process.

Building Automation – 

Saving more than construction costs! 

Intensive use of technical building 

equipment systems in modern 

buildings, a steep rise in the price of 

energy sources, increased demand for 

quality in new properties and modern 

living environments have meant that 

the use of automated control systems 

for the control and regulation of technical 

building equipment have become 

a must. 

According to data from several 

large consulting firms the use of au- 

tomation systems, whose price only 

constitutes on average 4% of the construction 

costs, makes it possible to 

substantially reduce operating costs. 

During the whole building’s life cycle 

(on average 50 years) the amount saved 

can be higher than the total construction 

costs. 

Comfort level requirements have in 

the meantime also become higher. For 

example it is hard to imagine a modern 

building without services such as heat- 

ing, ventilation and air conditioning. 

The result is that the total energy consumption 

of a property exceeds today’s 

standard on average by around one and 

a half to two times. 

Supply of additional electric power 

capacity costs approx. 3000 to 4000 

Euros per kW of electricity. With an 

average property consuming 1500 

kW above the standard amount, even 

the most expensive automation system 

which reduces energy consump- 


1

2 


tion costs much less than this energy. 

One must also consider that this additional 

electricity power supply is not 

always available, for example if there 

is nowhere available to build a power 

installation. 

Example 

Members of the Russian Association of 

Climatic Industrial Enterprises (APIK) 

equip modern properties with HVAC 

facilities and supply about 80% of the 

market sector in Russia. Building automation 

introductory courses by the 

Training and Advisory Center of APIK 

often show examples of calculations 

for the amount of investment in automation 

of technical building equipment 

systems. 

Partners of APIK found that during 

the realization of a project designed 

to equip a Moscow building complex, 

the equipment used in the property 

doubled the available supply. In order 

to reduce energy consumption, a 

whole set of different measures had to 

be implemented: use of energy-saving 

technology, realization of special algorithms 

to control the building’s technical 

equipment, which made the distribution 

to the largest energy consumers 

possible at that time. Only then could 

the entire energy consumption be reduced 

to meet the level of supply available, 

saving a large amount of money 

and avoiding future problems. 

Specialists from one of the leading 

companies, Korpus Group, submitted 

detailed statistics about the use of 

automated control systems in a property 

with a total area of 43,000 square 

meters and a severely restricted power 

supply. The completed system controls 

five main room types, with more than 

30 types of individual configurations, 

error diagnostics and remote control 

of appliances as well as archiving 

of all data. A broad deployment of 

LonWorks technology, made it possible 

to effectively distribute 4.5 mW 

of energy for cooling and 400 kW of 

energy for lighting the office zones. In 

this property, over 25,000 data points 

were installed. The total volume of the 

visualization system amounts to over 


800 graphic schemes, which are controlled 

by seven control stations. 

The automation enabled maintenance 

costs were considerably reduced, 

12%-17% of the energy was conserved 

and altogether between US$120,000 

and US$170,000 per year was saved. 

Additionally, thanks to continuous 

control of the data delivered by the 

cooling system controller, the operator 

was able to identify any changes in the 

plant operation. This led to a reduction 

in the level of repairs which would have 

cost US$12,000. This is only one of 

several examples. 

At the same time operating personnel 

could be reduced to eight people, 

bringing a further savings of 

US$93,000 per year as well as improving 

the operating quality of the entire 

technical building equipment. 

Training Program 

These examples show that under conditions 

of limited power supply and 

the demand for guaranteed stable and 

complex system control, the automation 

of new properties is necessary. 

Therefore, engineers, project managers 

and planners who specialize in the application 

of air conditioning equipment 

are increasingly posing more questions 

about automation. In order to be able 

to keep up with this demand for information, 

a special training course 

is being compiled by the Training and 

Advisory Center of APIK. This course 

is directed at chief engineers, architects, 

and specialists from management 

and investment companies and 

is devoted to methodological questions 

about work on projects, including the 

application of modern automated control 

systems.

Industrial-Class Controls 

The LonMark magazine is published 

with a particular theme every quarter; 

sometimes home systems, sometimes 

outdoor lighting, etc. Writing for this 

quarter’s theme was surprisingly difficult: 

the interfacing of industrial controls 

to the facility. Ironically, it wasn’t 

from lack of information available but 

rather, too much information. It is such 

a broad classification in LonWorks 

control descriptions. Purely looking at 

industrial automation, should I write 

about coal-mine safety applications? 

Incarceration controls? Nuclear reactor 

monitoring? Locomotive braking? 

Hospital security systems? Automotive 

paint-spray applications? Beer or wine 

making? Point-of-sale alcohol dispensing 

systems? Textile dyeing machines? 

Airport access systems? Or should I 

focus on the more aesthetic: lighting 

for the millennium celebration on the 

Eiffel Tower or the fountain show at 

the Bellagio Hotel in Las Vegas? 

Yes, LonWorks has filled a gap in 

industrial automation and has become 

a part of many automated processes. 

To be fair, LonWorks cannot replace 

systems that require precise, time-slotted, 

high-speed repetition – as would 

be found in DVD production, for example 

– but it could certainly drive the 

conveyor belt system that moves boxes 

of DVDs from one distribution point to 

another within a facility; and it could 

allow for the intercommunication of an 

automotive conveyor system in Detroit 

to communicate with one in Stuttgart 

or Honshu over the Internet.

Operation of a conveyor belt is one example of a function 

that can be tightly related to the sensors that must maintain 

count and product continuity across those belts. It is through 

asynchronous coordination that the LonWorks sensor detects 

a jam on a conveyor belt and notifies the drive motors 

of that conveyor system to reduce speed or halt the belt entirely. 

Asynchronous sensing and communication are strong 

points of LonWorks systems. But can we take this conveyor 

system further? That is to ask, what would we gain by tying 

the conveyor system into an HVAC system, for example? If 

a system running at high speed produces a certain amount 

of waste heat – and that system, running at a lower speed 

produces significantly less waste heat – then it would seem 

that tying the conveyor system into the HVAC system could 

result in significant savings through reduced cooling of the 

surrounding area. While the area could certainly be monitored 

for increased or decreased ambient temperatures, the 

direct correlation between the reduced conveyor system and 

a reduced need for cooling could result in greater efficiency 

due to the lack of time delay between the cause and the actuated 

response: The conveyor belt slows and the demand on 

the cooling system is reduced; rather than the scenario of 

the belt slowing, ambient room temperature dropping, and 

(after a latency period) the cooling system is reduced. 

Thus, we see another great benefit of LonWorks architecture: 

the ability to tie-in disparate systems through the 

use of unified technology. In high profile installations, such 

as the Eiffel Tower and the Bellagio Hotel, we see one-off installations; 

that is, a single Eiffel Tower and a single Bellagio 

Hotel fountain show. Both spectacular in their own right, 

they have very little need for integration with a facility. But 

in many applications, there is great opportunity for standardization 

of the facility-interaction functions: functional 

profiles of subsystem interaction. The members of LonMark 

have done this before with such successful subsystem interaction 

profiles as the “Elevator/Lift Fire-Systems Port” functional 

profile (profile number 140.41), where an independent 

vertical transportation system responds to the signals of a 

fire/smoke system; sending the elevator/lift cars safely to the 

ground floor and disabling the call-button functions. 

A similar interaction could take place between an office 

scheduling system and HVAC system, whereby knowledge 

of a meeting of 50 people to be held in a conference room 

can be the catalyst to ensure perfect temperature, lighting, 

and airflow are present just minutes before the start of the 

meeting – entirely by an automated process; one that balances 

environmental and fiscal responsibility with that of 

occupants’ comfort. 

Taking the ubiquitous “green” concept into consideration: 

energy curtailment can be facilitated by a tight interaction 

between the demand-response calls from a utility and 

the electrically actuated mechanicals of a facility; and – via 

the parallel path of the enterprise data systems – it can allow 

for checks-and-balances of curtailment need and curtailment 

availability.

In the days of pneumatic HVAC 

controls and head-and master/slave industrial 

systems, it was inconceivable 

to think that industrial facilities could 

be tied into enterprise systems and 

the greater facility as a whole. Today, 

it is quite common to hear of lighting 

systems, fire systems, HVAC systems, 

and others being tied together in an automation 

showcase of a building. But 

the idea of interfacing industrial controls 

to the facility is still such a nascent 

concept that no catchy term has 

been coined to adequately do it justice. 

“I2F,” perhaps? 

But this is the “LonMark” magazine, 

after all. We should be discussing 

LonMark certified components: 

Profiling the functions of interaction 

would seem to be the next logical step. 

Today, what we see more often than 

not is the development of entire I2F 

systems, customized from the ground 

up, with no reuse of components/objects 

from other installations. Why not 

standardize the I2F interaction; just 

as we have done in the building automation 

world? Efforts like those of 

the International Forecourt Standards 

Forum are leading the way: integrating 

petrol/gasoline station pumps, pointof-sale 

systems, and the lighting and 

HVAC systems of those mini-, drive-up 

facilities. 

The LonMark Industrial Task 

Group and the Building Automation 

Systems Task Group are just the right 

places for such a subsystem interaction 

to take place. Cross-participation in 

these groups is all it will take to create 

the functional profiles for an industrial-controls-to-facility 

port. I encourage 

all interested LonMark members 

to join us in blazing a brand-new path 

– to ride that conveyor belt from the 

factory floor to the office building.

Integrator’s Perspective 

The U.S. Department of Defense 

(DOD) LonWorks Guide Specs and 

Open Systems – An Update 

In 2000, Headquarters, U.S. Army 

Corps of Engineers (HQUSACE) 

called for the development of new 

guide specifications, with a specific focus 

on non-proprietary open systems. 

A four-year research and development 

project ensued. Extensive industry 

feedback and practical implementation 

expertise were sought. During 

this process a team led by the ERDC- 

CERL (Engineer Research and Development 

Center Construction Engineering 

Research Laboratory) investigated 

the breadth of what the industry had 

to offer including direct digital control 

(DDC), Modbus, LonWorks, BACnet, 

and vendor specific solutions. In 2004, 

the Corps released guide specifications 

for open controls systems based on Lon- 

Works, and began implementing them. 

The guide specifications are available 

for download from both www.wbdg. 

org and the LonMark website www. 

lonmark.org. 

In both 2007 and 2008, the U.S. 

Army Installation Management 

Command (IMCOM) funded the Corps 

to develop a strategy for the implementation 

of LonWorks systems at Army 

posts, and to implement this strategy at 

a few “trial” installations. (1) 

Requirement for Open 

It’s a typical story – Army installations 

were getting locked into singlevendor 

systems and saw service drop 

while prices increased. In addition, 

U.S. Government procurement rules 

require non-proprietary procurement 

as part of its contracting actions 

whenever possible. It’s important to 

note that the government definition 

of proprietary is different than that 

generally used by industry - for the 

government a system is proprietary 

if it requires or results in sole source 

procurement. While sole source 

procurement can be used if justified 

(due to being unavoidable), sole source 

procurement can be avoided using 

open systems technology. 

History of Army Corps 

of Engineers Guide 

Specifications for Digital 

Control Systems 

Until 2004 there were three Army 

Corps specifications: 

1. SLDC (Single-Loop Digital 

Control) – This consisted of nonproprietary 

systems based on 

standardized and interchangeable 

modular (non-networked) single 

loop digital controllers available 

from a variety of vendors. While 

there were pockets of acceptance, 

industry as a whole never fully 

supported this specification, and 

as industry advanced to more fully 

networked controls, this spec became 

obsolete. 

2. DDC (Direct Digital Control) 

– This consisted of networked 

DDC controls for HVAC with little/no 

supervisory interface. This 

specification did not address open 

vs. closed/proprietary systems, 

and often led to closed/proprietary 

systems. 

3. UMCS (Utility Monitoring and 

Control System) – This consisted 

of networked DDC controls for 

HVAC including the “front end” 

supervisory interface. The content 

of this spec overlapped the DDC 

spec, and this specification also did 

not address open vs. closed/proprietary 

systems and usually led to 

closed/proprietary systems.

The current (2004) specifications were primarily driven 

by the availability of open systems and a HQUSACE directive 

to rewrite the specs to avoid proprietary procurement 

(where proprietary means closed, locked-in, sole source). 

Time Frame 

CERL has been closely following the development of open 

systems (LonWorks and BACnet in particular) since the 

early 1990s; however, HQUSACE initially held that the 

technology was not mature enough for government adoption. 

The initial direction to pursue open systems came 

from HQUSACE in 2000, at which point CERL, Huntsville 

Engineering and Support Center (mandatory center of expertise 

for UMCS) and Savannah District (directory of 

expertise for DDC/HVAC controls) started a concerted investigation 

of open systems to determine the best way to 

proceed. By early 2001, the team had settled on LonWorks 

as the technology for the new specifications and then began 

determining what implementation of LonWorks would 

be used. By mid to late 2001, the team decided that a flat, 

LonWorks Network Services (LNS)-based LonWorks system 

would be the most open. 

Why Choose LON? 

The Corps initial selection of LonWorks was because 

LonWorks as a whole – including the ANSI-709.1 protocol, 

LonMark guidelines, device certification, the LNS database 

standard etc. - was the technology most ready for use in a 

specification for an open system. In other words, LonWorks 

provided the best chance of getting the most open system. 

Since this initial selection of LonWorks, CERL has continued 

to monitor alternatives (including BACnet), and has 

determined that it remains easier to get a more open system 

using LonWorks, and that the LonWorks system will be 

easier to maintain. 

What about BACnet? 

A specification for an open system cannot rely on contractors 

being willing to provide systems that interoperate. 

Too often BACnet (and to a lesser extent CEA-709.1) is 

described as a protocol that allows different vendors to interoperate. 

The unpleasant implication is that the protocol 

allows vendors to not interoperate. This is unacceptable; the 

fundamental goal is to develop a specification that would 

force (not “allow”) vendors to interoperate – any system 

installed according to the specification would interoperate 

and the vendor would no longer have control over whether 

the system would interoperate or not. This was determined 

to be easier to achieve with LonWorks than with BACnet. 

To explain the full reasoning behind this conclusion would 

require more space than is available, but in summary: 

1. 

Using only CEA-709.1 and CEA-852 (“LON over IP”) 

to create a flat network, supervisory controllers/gateways 

which use proprietary communication or rely on 

2. 

3. 


proprietary elements can readily be avoided. There is 

no piece of closed hardware that has to be part of the 

building control system which therefore facilitates open 

procurement of the building controls. 

The availability of a common and supported database 

standard (LNS) allows for the minimization of device/ 

network configuration tools. By additionally requiring 

LNS Plug-ins and controller configuration through 

SCPTs, UCPTs and SNVTs, one LNS network configuration 

tool can be used for the entire system. 

It’s easier to limit the options with LonWorks. While 

options may be good for features, they tend to provide 

opportunities to close the system. Since the Corps’ goal 

is an open system that is functional for the needs of 

the average installation, options can be limited and increased 

openness can be had without the risk of losing 

required functionality. 

In 2006, ERDC-CERL re-evaluated the feasibility of creating 

specifications for an open system using the BACnet 

protocol and concluded in part that: “while it is possible 

to write “Open enough” [nearly as open as the currently 

specified LonWorks system] BACnet-based BAS specifications, 

the effort will be challenging and prescriptive, and 

will require a greater level of enforcement than an equivalent 

ANSI/CEA-709.1 (LonWorks) based specification. The 

resulting system will not integrate as tightly or be as userfriendly 

to installation operations and maintenance staff as 

a LonWorks system based on the existing Unified Facility 

Guide Specification [UFGS]) due mainly to the need for 

multiple configuration tools and issues in establishing and 

maintaining device communications.” (2) 

HQUSACE opted not to fund the development of guide 

specifications based on BACnet. 

What are the Primary Goals for the 

Creation of the Specs? 

The primary objective is to allow Army installations to have 

a UMCS consisting of a single front-end integrated to multiple 

building control systems procured from multiple vendors 

in a non-proprietary manner. This was the direction 

provided by HQUSACE when the specification development 

began, and it is a major factor in determining what the specifications 

will require. 

Of course, the system must also be functional, but this is 

a relatively easy goal since most Army posts do not require 

many features. 

The system needs to be easy to maintain – and the simpler 

the entire system is, the easier it is to maintain. Thus a 

system with one network configuration tool to learn is preferred 

over a system with several. 

When evaluating trade-offs, the specifications have 

almost always been willing to sacrifice “bells and whistles” 

for openness and ease of maintenance.

Training and Support 

Headquarters U.S. Army Corps of Engineers (HQUSACE) 

is responsible for developing and maintaining criteria. 

HQUSACE also designates Centers of Expertise. With regard 

to support for building automation systems, this includes 

Huntsville Engineering Support Center (HNC) and 

Savannah District (SAS). 

HNC is the mandatory Center of Expertise (MCX) for 

UMCS systems and Savannah is termed the Directory of 

Expertise (DX) for HVAC Control Systems. Many UMCS 

systems installed at Army installations are through contracts 

awarded by HNC using pre-qualified IDIQ (Indefinite 

Delivery/Indefinite Quantity) contractors/suppliers. This 

contracting process provides HNC the ability to identify 

and evaluate suppliers and contractors that meet strict 

guidelines. A pre-qualified set of suppliers can then be contracted 

quickly for a specific project. HNC has several IDIQ 

contracts in place and a team of vendors able to support the 

LonWorks Guide Specifications. 

The U.S. Army Corps of Engineers USACE Learning 

Center (ULC) offers training on LonWorks Control systems 

with a one-week course entitled ‘HVAC Control Systems: 

Design and Quality Verification”. This course includes 

two days of focused instruction on LNS-based LonWorks 

technology as applied to the systems specified in the DDC 

and UMCS Guide Specifications. Huntsville also offers an 

HVAC Control Systems Operation and Maintenance training 

course which includes an overview of and introduction 

to LNS-based LonWorks. 

As the lead technical organization in the development of 

the specifications, CERL is the primary source of technical 

expertise on open systems for the Corps. Through IMCOM 

sponsorship CERL also heads the effort to develop an implementation 

strategy for Army LonWorks systems and in 

coordination with HNC and SAS works directly with installations 

to implement the specifications. CERL consequently 

serves as a source of technical expertise for Corps districts 

and installations in the review of specific projects and for 

assistance in resolving technical issues related to the implementation 

of control systems. 

IMCOM also sponsors a yearly LonWorks building automation 

systems (BAS) implementation workshop. The ini- 

Figure 1 Projected MILCON Budget FY06-FY1 


Figure 2. LonWorks building automation system architecture. 

tial workshop was held at Fort Hood, Texas and included a 

demonstration of Fort Hood’s award winning UMCS. Fort 

Hood recently received an Army Secretary Innovation Award 

for its UMCS and this past year also received LonMark 

International’s Multi-Vendor Project of the Year award. 

What are the Budgets and Scopes for 

MILCON over the next few Years? 

The budget for military construction (MILCON) is 

US$69.6 billion for projects from 2006 to 2013. As shown 

in the chart(3) below, peak spending periods are in 2008 

and 2009. With these projections and the need to control 

energy, the reliance on a solid set of guide specifications is 

critical to the overall plan. Note that U.S. military spending 

is not confined to the U.S.; construction in Japan, Korea, 

and Europe will total US$3.5 billion. 

Technologies Covered 

by the Specifications 

The specifications focus on HVAC, but other technologies 

such as metering, lighting, and occupancy can readily be integrated 

into the flat, LNS-based LonWorks system defined 

by the specifications. 

Architecture 

The specifications separate the building automation system 

(BAS) into two parts: 

� one or more Building Control Systems (BCS), which 

perform stand-alone control 

� a Utility Monitoring and Control System (UMCS) consisting 

of a single front-end (with multiple optional client 

workstations) and a post-wide network 

The architecture consists of a CEA-709.3 (TP/FT-10) network 

for the building control system connected to an IP 

network using a CEA-852 router as the Building Point of 

Connection (BPOC) as shown in Figure 2. The specifications 

un-bundle the building controls from the Utility Monitoring 

and Control System (UMCS), so the building contractor 

provides only the TP/FT-10 network and the UMCS contractor 

installs the BPOC and connects the system to the 

UMCS (see Figure 3).

Key Specification Requirements 

Neither CEA-709.1 nor the LonMark Interoperability 

Guidelines are sufficient to guarantee an open system. For 

example, the specifications require application-specific controllers 

to be LonMark certified, but this does not guarantee 

the presence of many necessary SNVTs as they are 

optional in the Functional Profile. The specifications therefore 

include Points Schedules fully documenting the needed 

network inputs and outputs. 

There are other instances where additional requirements 

are needed to ensure an open system. While these requirements 

are not directly part of the CEA-709.1 protocol or 

the LonMark guidelines, they are supported by these standards 

and help ensure an open system. Example requirements 

from the specifications include: 

� 

� 

� 

All network communication must be via SNVT 

All device configuration must be via SNVT, SCPT and 

UCPT 

All configuration must be via LNS 

Figure . LonWorks building automation system architecture 

unbundled by spec section and contractor responsibility. 

Application of the Specifications 

The guide specifications are guides and their use, while 

strongly encouraged, is optional. Unfortunately projects still 

proceed without the use of the guide specifications which results 

in proprietary systems, including proprietary BACnet 

and LonWorks systems. On the other hand, the availability 

of the guide specs is a powerful incentive to use them since 

design engineers seldom have time to develop a new specification 

from scratch. In addition, the support structure and 

resources within the Corps of Engineers (such as Huntsville, 

Savannah, CERL) are all geared towards supporting open 

systems based on the guide specs. For example, requests 

to CERL for assistance with other systems are not turned 

away, but preference is given to systems based on the guide 

specs and the first question is always “Are you using the 

guide specs? If not, why not?” 

The typical Army installation has many buildings (thousands, 

in some cases) but, ideally, a single UMCS front end. 


A typical construction project might involve controls at one 

or more (typically less than 10) buildings at a time. In this 

environment, the Army lets many contracts for building 

controls, but only one contract for a UMCS. 

The ideal use of the specifications is for a one-time procurement 

of the UMCS (usually with some BCSs installed at 

the same time) to be followed by repeated procurement of 

BCSs which are then integrated into the UMCS. The BCS 

are procured, tested and commissioned prior to connection 

to the UMCS to ensure that all requirements have been met. 

The system can then be integrated to the UMCS and the supervisory 

functions configured. 

By procuring building control systems separately from 

the UMCS, and separately from integration to the UMCS, 

the system remains more open. There are some closed aspects 

to the UMCS in that the integration has to be done 

by someone with knowledge of that system (which generally 

means someone working for the manufacturer of that 

system) but the building controls can be procured without 

regard for the UMCS. The specifications also require the 

UMCS to be fully licensed to the Government so that anyone 

with the knowledge can perform the integration (the 

UMCS software manufacturer cannot control access to the 

system). 

The Government’s recent move towards design-build 

projects means that the integration is often specified along 

with the building controls, which extends the competitive 

advantage to the BCS contractor. CERL is looking into 

ways to avoid this situation, but the burden of addressing 

the problem may rest largely on the industry since these are 

design-build projects and the government has little control 

over how the controls contractor(s) are selected.

Somfy Controlling and 

Motorised Systems for 

Blinds – Interior sun 

protection energy shows 

saving potential 

The Encoder Motor Technology 

Concept 25 is connected to an animeo 

Motor Controller by Somfy and 

ensures reliable interior sun and glare 

protection. Used in a compact head rail 

system measuring 25mm x 25mm and 

upwards, it can reduce cooling costs 

and is suitable for interior window application, 

in the space between doubleskinned 

façades or partitioned walls. 

Modern buildings require sophisticated 

sun protection systems. Saving 

energy costs and maintaining optimum 

workplace lighting conditions are priorities 

in smart solution applications. 

Planners and operating authorities 

choose between a sun protection system 

on the façade exterior, in the space 

between double-skinned walls, or in 

building interiors. 

High winds and 

interior sun protection 

An interior-positioned system integrated 

into the façade has advantages during 

strong wind conditions. Exterior 

elements automatically move upwards 

to prevent material damage when wind 

speeds reach 50-60 km/h providing 

no glare or sun protection which can 

cause an increase in room temperature. 

Interior blinds are recommended 

for buildings over 10 storeys as wind 

strength increases higher up the building. 

Façade-integrated sun protection 

is ideal for temporary strong wind geographical 

zones such as coastal areas.

Interior positioned elements reduce 

cooling loads, providing a 10% 

saving. Blind integration between the 

wall façades is an alternative, lowering 

energy room cooling costs by almost 

30%. 

Higher functionality 

with encoder motor 

and LON Controlling 

The encoder technology based on 24 

volts is the interior sun protection system’s 

core. Somfy’s encoder motor LW 

25 E83 gives continuous blind position 

and speed messaging allowing 

optimum running and exact slat angle 

positioning with slower slat turning 

speed via the Somfy hand transmitter. 

A patented scroll wheel allows fine 

adjustments and on moving slat angles 

the Modulis hand transmitter ‘My’ 

press buttons store preferences, making 

recall simple. 

Control system learned-in end positions 

remove blind mechanics’ load 

increasing life expectancy. The encoder 

technology makes determination of 

bottom end position, making mechanical 

shaft blocking obsolete. Blinds are 

therefore thinner, fitting a compact 

head rail system or even small 50cm 

wide windows. 

The animeo LON 4 DC-E Motor 

Controller controls the encoder. 

Developed according to LonMark 

Guidelines it is ideal for controlling 

up to four individually parameterable 

interior Venetian and roller blind motors. 

The animeo LON 4 AC Motor 

Controller controls roller shutters, 

awnings and windows. Potentiallyfree 

contacts such as window contacts, 

room thermostats or occupancy sensors 

can be connected through eight 

binary LON inputs. Sun tracking and 

temperature measurement functions 

guarantee optimum blind control 

analogously to time of the year and 

day. Additionally, the animeo Motor 

Controller prevents glass damage 

through thermal breakage via doubleskinned 

façade positioning. 

Somfy’s motor and controlling 

technology has many applications – as 

an interior sun protection system, for 


partitioned walls in office areas and as 

a double-skinned façade between-wall 

solution.

Data Comparison with 

Distributed Logging 

Systems – GipsySync 

from Gesytec 

GipsySync from Gesytec synchronizes 

data from decentralized technical facilities 

and real estate with a central 

database and supplies the operator 

with information about consumption, 

status and the history of all facilities 

for accounting, system maintenance or 

optimization. 

Gipsy product range stations from 

Gesytec are used as data accumulators 

and converters in building technical facilities 

and real estate. Apart from storing 

and collecting utility counter data, 

Gipsy stations document data about 

heat consumption, temperature gradient, 

etc. 

Stored and logged values from the 

Gipsy station can be transmitted to a 

distant central data center where data 

from all properties is collected and 

made available. 

Consistent control center evaluation 

requires current and verified data 

transfer realized using a dedicated line 

allowing continuous data transfer. 

Alternatively, data can be collected 

locally in a SQL-compatible database 

and intermittently transferred to the 

central database. 

GipsySync keeps 

you up-to-date 

GipsySync is a PC application which 

runs on all current versions of Windows 

and data filing is realized by the Gipsy 

stations in their embedded SQL database. 

GipsySync is easily installed on 

the central data server or linked PC. 

Data links connected to any decentralized 

Gipsy server are mirrored in the 

central database and vice versa. This 

data synchronization, which is made 

over the telephone or DSL using TC/IP 

as the communication protocol, ensures 

that the central database is current. 

Detailed invoices for specific periods 

and consumers, calculated on this 

extensive data, are not only available 

for water consumption, electricity, or 

heating, but also for pro-rata use of air 

conditioning. 

Gipsy stations are ideal for heterogeneous 

environments whether data originates 

from gas, water, electricity or air 

conditioning flow rate or other systems 

- LON, M-bus etc – Gipsy stations collect 

everything and transfer the data to 

the central database via the GipsySync. 

Individual systems for every type of 

consumption are obsolete. Additional 

environment parameters gathered can 

be used for plant operation monitoring 

and analyzing. 

Malfunctions, damage, and waste 

can be recognized in time. Water pipeline 

leaks, for example, can be discovered 

by frequent examination of the 

consumption history showing water 

being “used” when the consumer is 

absent.

GipsySync is applicable bi-directionally 

allowing halting or changing 

time switch programs by new control 

center specifications downloaded into 

the Gipsy stations. All Gipsy stations 

have, as embedded PC, the ability to 

run switch and control tasks. 

Settings, such as what data is transferred 

from which station database table 

to where in the control center, how 

often and when a connection has to be 

established, whether data is held or deleted 

after transmission are possible on 

GipsySync web interface. 

The Gipsy is the solution whenever 

large amounts of data from diverse systems 

are combined and made available 

centrally. Data required for consumption 

accounting or as a detailed distributed 

facilities optimization history is 

supplied quickly and efficiently by the 

Gipsy.

Neutrino-GLT Version 9 

from Kieback&Peter 

The Neutrino-GLT Version 9, the newest 

version of Neutrino-GLT building 

management technology, offers a 

comfortable operating interface and 

new useful functions for data evaluation 

and long lasting installation 

optimization. 

Each user can design an individual 

operating menu on the newly designed 

operating interface. There is also a 

TOP-5 function list for quick access to 

frequently used programs as well as a 

system monitor which continuously 

provides details on the status of the 

system. 

Data evaluation and installation optimization 

have each been significantly 

simplified with these new functions. 

Operation of the trend curve is even 

more intuitive and its design offers even 

greater clarity. Options such as colour, 

form, scale, etc. can be directly modified. 

With a second timescale it is possible 

to compare, directly 

onscreen, a trend curve 

or even an entire macro 

with another chosen time 

period. 

Comprehensive information 

from the data 

processing can be generated 

and displayed in different 

reports, e.g. as tables, 

bar, or pie charts. 

The comparison of 

meter data in various 

time periods makes analysis 

and statistical evaluation 

simple. 

A fault indicator statistic 

provides information on when a 

malfunction first took place, how often 

it reoccurred, and how long it lasted. 

The fault indicators are stored in a database 

so that statistics for each time 

period can be retrospectively prepared. 

All statistics can be automatically 

converted into a CSV table which can 

be further processed using any conventional 

office program. 

Important notifications can be directly 

converted by means of a TTS 

Module (text to speech) into a spoken 


message. The spoken message is consistent 

with the message text and is issued 

over a PC speaker or telephone. 

Project planning is also uncomplicated 

for large data volumes. The GLT 

sorts according to appliance, address, 

data point type, and relevant application 

to which the data point is linked. 

With the new search and filter possibilities 

of Version 9, the user can find each 

data point quickly and precisely. 

The parameters of each data 

point, for example long-term logging, 

consumption notification, or external 

access by ODBC, can be quickly 

changed, deleted, or assigned via program 

parameterization. 

The Neutrino-GLT Version 9 offers 

possibilities for making savings in documentation. 

Before the print is started, 

a preview for every installation picture 

and parameter list is produced, and the 

user can decide on the correct documentation. 

During the printing of fault 

notifications the queue management 

system can be adjusted so that each 

piece of paper is only printed when a 

complete page is full. The notifications 

are documented together and paper is 

saved at the same time.
