Energy Star Benefits Of Airsealing

According to ENERGY STAR®, the U.S. Environmental Protection Agency’s trusted energy efficiency program, air leakage can account for 25–40% of the energy used for heating and cooling in a typical home. Air leakage doesn’t just waste energy—it also reduces indoor comfort, allows in moisture, dust, and pollutants, and increases the risk of mould and structural damage. ENERGY STAR®, is the U.S. Environmental Protection Agency's trusted energy efficiency program. They highlight that airsealing the building envelope during construction is one of the most critical and cost-effective steps to create more energy efficient, healthier, more durable homes that are lower-cost to operate. Combined with controlled mechanical ventilation, air sealing helps deliver homes that feel better to live in, protect occupant health, and meet growing expectations for quality and efficiency.
