How Aeroseal works in Commercial Buildings
Aeroseal duct sealing is used in commercial buildings around the world to increase energy efficiency and improve comfort and indoor air quality. This video takes you inside a typical commercial duct sealing project, highlighting the steps involved in using this safe and easy-to-administer process.
High Energy Consumption
If you want to reduce your energy consumption without a large capital expenditure, you should consider having your ducts tested for leakage.
Duct leakage can more than double fan energy use, and increase heating and cooling costs significantly. According to ASHRAE, just a 20% leakage in an exhaust system can increase fan energy use by 95%. Your energy savings potential is magnified by the fact that excess flow due to leakage often creates uncontrolled air infiltration through the building envelope or excess outside air intake through the HVAC system.
The investment in Aeroseal duct sealing is typically recovered in 3-7 years. According to the U.S Department of Energy and several other sources, Aeroseal duct sealing is one of the best energy saving solutions for property owners – and one of the most cost effective.
Poor Exhaust from Desired Areas
Duct leakage has been linked to bad Indoor Air Quality, poor humidity control and health hazards such as sick building disease and the spread of mold and other contagions within the building.
If you are having trouble getting the correct air changes per hour or trouble pressurising some zones within your building, it could be due to duct leakage. When 20% or more of the air that is passing through your ducts is leaking out, it is not surprising that some of the zones are not getting enough air.
In tall buildings seasonal stack effects and wind loading often increase the ventilation problems from improperly sealed toilet and kitchen exhaust systems. Buildings with self-regulating exhaust dampers are particularly prone to excessive energy consumption and poor indoor air quality associated with leaking exhaust shafts.
Problems Identified During Building Commissioning
In a recent survey, over 74% of commissioning professionals agreed that buildings have significant duct leakage.
If the HVAC cannot be properly balanced or you are not getting adequate flows through some supply diffusers or return grilles, you should consider getting your duct system sealed with Aeroseal. Aeroseal is able to seal leaks in otherwise inaccessible duct systems is both new and existing buildings.
Problems Identified by Test and Balance Report
If a Test and Balance report shows that you are not getting adequate flows to some grilles, or that the grille flows do not add up to the flow at the fan, you should consider getting your duct system sealed with Aeroseal. Aeroseal is able to seal leaks in otherwise inaccessible duct systems in both new and existing buildings.
Increased Cooling or Heating Capacity Needs
If your cooling or heating needs have increased, perhaps due to higher occupancy, you may be able to meet the increased needs simply by sealing the leaks in your duct system.
If your ducts are leaking 20% of the air that they are supposed to be delivering to the zones, simply sealing those leaks can increase your ability to cool zones with increased cooling loads. Aeroseal generally seals 80-90% of the leakage encountered.
