“71% of units have some kind of
problem that affects performance with
an average of 1.9 problems per unit”
New Buildings Institute
"Refrigeration Systems have on average
10.5% gas leakage per year“
Ralf Birndt, Rolf Riedel, Dr. Jürgen Schenk –
Germany
“More than 10% of energy is wasted due to
excessive run time and equipment
problems“
PIER - Public Interest Energy Research
• No one knows machines
are operating with
problems
• Problems often do not
immediately result in
comfort or production
impact
• Problems DO immediately
result in higher energy,
maintenance, and
equipment costs
• Existing Alarms are often
not prioritized & ignored

OPERATING PERIOD
75% of Expenses occur in the Operating Period, which
supports the need for solutions that continuously optimize
All the time & focus is in the development period

TRENDS
• Electricity Cost is Increasing at a Double Digit Yearly Rate
• HVAC-R Accounts for the Majority of a Building’s Energy Use
• 80% to 75% of HVAC-R Costs are in the Often Ignored Operating Period
• The Majority of HVAC-R Equipment and Systems are Working Bad and
No One is Aware
• Skilled technicians are in demand
• It is popular and in some cases required to be GREEN

Intelligent Building Application
WHAT IS FDDI?
Automatically identify minor machine faults before they escalate into
large financial, operational, or comfort problems
10

BENEFITS
“A/C – Systems are able to operate with about 35% less energy.”
Results from the E.U. sponsored SAVE program
“FDD can result in a continuous
10-30% energy savings, support
efficient maintenance practices,
extend equipment life, and provide
more consistent occupant comfort
and indoor air quality.”

Sensus MI Solution
• Auto early problem detection
with severity, & financial impact
• Notification via a web browser
or with a remote escalating e-
mail, SMS, RSS, or phone call
• Technician has required skills
and parts to fix with one trip
• Parts ordered and maintenance
scheduled in advance
• Emergencies avoided & work
done only when needed
• Service load smooth
• Downtime & problem spread
avoided

performance of buildings (EPBD)
Article 9: Inspection of air-conditioning systems
With regard to reducing energy consumption and limiting carbon
dioxide emissions, Member States shall lay down the necessary
measures to establish a regular inspection of air conditioning
systems of an effective rated output of more than 12 kW.
This inspection shall include an assessment of the air-conditioning
efficiency and the sizing compared to the cooling requirements of
the building. Appropriate advice shall be provided to the users on
possible improvement or replacement of the air-conditioning system
and on alternative solutions.

PRODUCTIVITY
The biggest cost of a building is the
people, goods, or processes inside of it.
HVAC-R downtime results in very costly
comfort, health, customer satisfaction, and
production issues.
Prevent losses and avoid:
-- Low human productivity
-- Downtime of mission critical equipment
used in data centers, production processes,
and to maintain perishables.
