Decarbonization Impacts

Operational Emissions

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 impact 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.

Embodied Carbon

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.
