While energy savings and CO2 reductions will vary significantly by building type (high rise, low rise), fuel type (steam, electric), and solution (ventilation rehabilitation, envelope sealing, or both), any reductions in the amount of energy wasted through air leaks will have a direct implact on carbon emissions as well. In fact, using an example of a New York City building, a recent study in the ASHRAE Journal showed that with pre-seal leakage of 16%, the Aeroseal energy model proved out savings across the categories of:

• Reduced fan power

• Reduced cooling and heating loads

• Lower reheat requirements in VAV (variable air volume) systems.

• Reduced peak electrical demand with results suggesting roughly 1% incremental energy savings for each percentage point of leakage sealed — representing substantial energy-saving and carbon-reducing potential for commercial and multifamily buildings; especially where initial leakage is high.

AeroBarrier helps reduce a building’s embodied carbon by improving the overall effectiveness of the insulation system. Because the building envelope is much tighter, builders can often reduce or eliminate high-carbon materials like spray foam, use less traditional insulation, and even specify lower-performance windows — all while maintaining the same energy performance targets. Since AeroBarrier’s sealant itself has very low embodied carbon, it adds virtually no additional eCO₂ impact while enabling meaningful reductions in other, more carbon-intensive materials.
