ENERGY WASTE IN
BUILDINGS TODAY
ASHRAE estimates most commercial buildings experience 10-25% air duct leakage. This requires HVAC systems to work more than necessary to keep buildings at comfortable temperatures.
A recent study from the Building Commissioning Association quantified duct leakage as a $2.9B problem.


BUILDINGS ARE BLOWING
ENERGY DOLLARS AWAY!



Increased Fan Energy
Poor Air Quality
Ongoing Operating Costs
The more air that leaks out of your ducts, the harder your fans have to push to reach the desired space. Duct leakage leads to excess ventilation loads, which in turn drastically increases your energy costs.
Leaks in the return duct allow airborne allergens, viruses, and bacteria to be sucked into the duct system. These contaminants are then spread throughout the facility, compromising air quality for other occupants.
Leaky ductwork is the primary cause of ineffective building exhaust, causing problems with uneven and uncomfortable temperatures that can lead to higher energy bills, and added maintenance costs.
INTRODUCING OUR PROVEN
DUCT SEALING PROGRAM
We combine energy advisory services, experienced technicians and award-winning technologies to eliminate duct leakage and unnecessary energy waste.
The Duct Sealing Program provides a cost-effective,
non-disruptive solution to eliminate energy loss, maximize HVAC efficiencies and reduce carbon footprint.

INCREASE VENTILATION. REDUCE ENERGY. OFFSET CARBON.
The Duct Sealing Program allows facilities to significantly increase air volume and exchange rates
by rehabilitating ductwork infrastructure and sealing leaky ducts.
As a result, buildings can significantly improve indoor air quality, eliminate unnecessary energy waste and reduce carbon emissions - without the need for costly mechanical upgrades.
COMMON DUCTWORK DEFICIENCIES:

-
Defective infrastructure
-
Leaky Ductwork
-
Poor Installation Practises
-
Aged and antiquated sealing
-
Adjusted ductwork due to retrofits
-
Accidental damage from other projects
-
Clogged coils and diffusers
-
Defective fire dampers
-
Obstructed balancing dampers
-
Acoustic screening restricting airflow
