ABB drive saves<br />

energy at the FA<br />

A 22kW variable speed drive from<br />

ABB is helping staff keep their<br />

cool at the Football Association’s<br />

headquarters in London. By varying<br />

the speed of the building’s air<br />

handling fan to match the changing<br />

pressure in the air ducts precisely,<br />

the drive is also helping<br />

the FA save energy.<br />

The drive, supplied by ABB HVAC<br />

partner DH Drives via air movement<br />

equipment manufacturer Flakt<br />

Woods, was part of a wider upgrade<br />

of the Soho Square building’s systems.<br />

This was spurred by the need<br />

to include humidification in the air<br />

conditioning system for the first<br />

time. Building engineer David Bane<br />

Somfy control puts<br />

new school in shade<br />

Somfy, a world leader in blind<br />

control systems, has played a significant<br />

part in making a College<br />

assembly hall capable of transformation<br />

into a performance theatre<br />

with full blackout facilities.<br />

The distinctive design of Bishops<br />

Park College in Essex, a £15m PFI<br />

project for Wates Construction,<br />

created a number of shading challenges<br />

for blinds contractor<br />

Nantmor Blinds.<br />

Inspired by an example in Boston,<br />

USA, the college is organised into<br />

three separate ‘self contained’<br />

schools, the focal point of which is<br />

an imposing multi-purpose shared<br />

hall.<br />

Used primarily as an assembly hall<br />

and refectory, the spacious double<br />

volume hall is top-lit with natural<br />

light by a 49 square metre pyramid<br />

explains: Without humidification<br />

the relative humidity of the air was<br />

dropping below healthy levels,<br />

especially in the winter. Now the<br />

upgraded system is saving energy<br />

and is making everyone feel more<br />

comfortable.’<br />

The air in the building is filtered<br />

and the pressure drop across the<br />

filters changes as they gradually<br />

become clogged with dust. In the<br />

old system, the air handling unit<br />

constandy pushed air through the<br />

ducts as if it was working against<br />

the maximum back pressure from<br />

the filters. We used to use loads<br />

more energy and we’d also find<br />

unstable pressure conditions within<br />

the air ducts,’ says Bane. ‘Now the<br />

ABB drive is connected to the building<br />

automation system and varies<br />

the fan speed to maintain a constant<br />

duct pressure. It saves energy<br />

and makes the whole system more<br />

stable.’<br />

According to Bane, the FA is still in<br />

the process of quantifying the<br />

energy savings from the drive. Any<br />

quantitative assessment is complicated<br />

by the fact that the addition<br />

of the humidification unit is also<br />

saving energy, because passing the<br />

air over the water cools it down<br />

and makes the air conditioning less<br />

reliant on electrical cooling.<br />

rooflight 15 metres above floor<br />

level. The building also incorporates<br />

68 metres of clerestory windows<br />

positioned five metres above<br />

a first floor balcony walkway.<br />

Nantmor Blinds’ task was to provide<br />

the hall with a blackout capability,<br />

necessary for its third main<br />

role as a performance theatre.<br />

Working closely with Wates’ project<br />

design manager, project architects<br />

ACP Architects and the college’s<br />

headteacher, Nantmor specified<br />

and installed eight triangular<br />

Techtonic AV88 non-retractable<br />

overhead dimout blinds with side<br />

masking in the rooflight. Powered<br />

by Somfy motors, the blinds are<br />

hard-wired to a wall-mounted key<br />

operated switch.<br />

“In such a situation, where access<br />

is difficult, it is imperative that<br />

only the most reliable, low-maintenance<br />

product is used, in the interests<br />

of the supplier, end-user and<br />

facilities management team,” said<br />

Nantmor’s Terry Feek. “We carry<br />

out a significant number of installations<br />

throughout the education sector<br />

and have always found the<br />

Techtonic range of roof blinds to be<br />

extremely cost-effective and reliable.<br />

They all feature Somfy<br />

motors, which are maintenance<br />

free and the industry standard.”<br />

Truvox launches low<br />

moisture carpet<br />

cleaning system<br />

Increased productivity gains,<br />

reduced cleaning costs and cleaner,<br />

better looking carpets are just<br />

some of the major benefits<br />

offered by the new Cimex-Encap<br />

Low Moisture Carpet Cleaning system<br />

from Truvox.<br />

Based on a simple yet effective<br />

process, the system involves scrubbing<br />

a specialised polymeric cleaning<br />

solution deep into the carpets<br />

fibres to emulsify then encapsulate<br />

all soil particles, before their simple<br />

removal by vacuum. Ideal for<br />

highly trafficked or heavily soiled<br />

commercial carpets this deep<br />

Excel Web controller<br />

for buildings ensures<br />

free vendor choice<br />

Honeywell has introduced Excel<br />

Web, an IP-enabled controller for<br />

building automation that ensures<br />

a free choice in selecting HVAC<br />

plant vendors - now and in the<br />

future - and secures investments<br />

in plant.<br />

Excel Web reduces costs enormously,<br />

as an existing IP network infrastructure<br />

(Ethernet LAN/WAN) can<br />

be used for the plant controllers;<br />

there is no need to run an additional<br />

bus through the whole building,<br />

as communication between Excel<br />

Web controllers in different buildings<br />

can use existing network<br />

cabling.<br />

Excel Web is license-free and offers<br />

the highest level of independence<br />

and network security in the marketplace,<br />

with the combination of<br />

BACnet ® and LonWorks ® open protocols,<br />

easy operation and remote<br />

services via Standard Browsers<br />

including Internet Explorer and<br />

Mozilla <strong>Fire</strong>fox, plus increased networking<br />

security using LINUX.<br />

Excel Web provides direct access<br />

via Intranet or Internet; there is no<br />

need for additional routers. It is<br />

completely independent of proprietary<br />

operator interfaces. Any<br />

standard notebook, laptop panel or<br />

cleaning technique effectively<br />

removes both dry and sticky soils to<br />

ensure there is no future soil<br />

attraction, so carpets stay cleaner<br />

for longer. In addition, as it is a low<br />

moisture process carpets dry faster<br />

and can be put back into use soon<br />

after cleaning.<br />

For best results simply pre-vacuum<br />

the carpet to remove as much dry<br />

soil as possible. Next apply correctly<br />

diluted Cimex-Encap solution to<br />

the carpet using a 3-brush<br />

machine. The Cimex machine provides<br />

the necessary agitation needed<br />

to reach and loosen even the<br />

most toughest and<br />

stubborn deep set<br />

soils, immediately<br />

making the carpet<br />

look brighter and<br />

cleaner. As the<br />

Cimex-Encap solution<br />

dries it encapsulates<br />

the soil in a<br />

crystal. Once dry,<br />

normal, routine vacuuming<br />

will remove<br />

all of the encapsulated<br />

soils.<br />

touch-panel PC with an Internet<br />

Browser can be used. It has a builtin<br />

web server and is completely<br />

independent of external web<br />

servers.<br />

It also features built-in remote service<br />

capability, including firmware<br />

and application download, readout<br />

of online trend buffer, and<br />

trend and read-out of LON communication<br />

statistics.<br />

Excel Web integrates into every<br />

network security concept and is<br />

firewall friendly: it requires only<br />

two ports, HTTP and BACnet, and<br />

does not use ActiveX. The web<br />

server can be disabled for critical<br />

applications, such as on military or<br />

pharmaceutical sites.<br />
