Lower your building's energy consumption and costs

Aeroseal® Duct sealing is one of the most effective strategies to reduce energy waste in commercial buildings

Guaranteed Energy Savings

Aeroseal® duct sealing addresses multiple sources of energy waste, commercial contractors and ESCOs use it as an ECM to gain flexibility in reaching energy-saving goals.

Lower HVAC Requirements

60% of a building’s HVAC energy goes to its fans. Studies show reducing leaks 15% drops fan requirements by 40% or more – saving thousands of dollars every month.

Shrink Energy Waste

Duct sealing reduces energy waste by eliminating the cracks and holes in ductwork that draw unconditioned, contaminated air into the building.

Reduce System Costs

Energy costs are reduced by increasing the efficiency of the HVAC fans and by eliminating excess ventilation loads.

    Why should ducts in commercial buildings be sealed?

    Duct sealing in commercial buildings cost-effectively saves energy, improves air balance and thermal distribution (comfort and ventilation), helps comply with building codes and reduces cross contamination between different zones in the building (i.e., smoking vs. non-smoking, bio-aerosols, localised indoor air pollutants).

    How much energy does the sealing process save?

    Energy savings are different for light commercial vs. large commercial buildings and obviously depend upon the initial duct leakage level. The Aeroseal Energy Savings Excel spreadsheet can be used to estimate the savings for both types of buildings. For ducts above an insulated ceiling in a light commercial building, energy savings should be 10–30% of HVAC energy use, and peak electricity-demand reduction is generally a higher percentage. In a large commercial office building with a VAV system, energy savings and demand reduction should be 20–40% of fan-system energy use and 5–10% of cooling energy use. As a rough estimate, excluding any of the non-energy benefits of duct sealing, simple payback times typically range from 1 to 4 years, and return on investment between 30% and 70%.

    How do I know if the ducts in my building need to be sealed?

    The existence of duct leaks in your building can be uncovered several ways. One way is to examine Test and Balance reports, comparing the total flow through the grilles with the total flow through the air handler, or by looking for systematically low flows at grilles that are far from the fan. Another way is to test a sample of duct sections for leakage, a test that Aeroseal technicians perform on a regular basis.
