Green Building Energy Services provides a range of Air Sealing services to improve the energy efficiency of homes. • Weather-stripping • Caulking • Environmentally Safe Foam • Ventilation improvements Whole home air sealing involves a range of services and weatherization measures to reduce air leakage. Air sealing is one of the most effective energy efficiency improvements that can be made to your home. Air sealing involves creating an effective air barrier to prevent unwanted air from entering and leaving the home. With proper weather-stripping, caulking, environmentally safe foam, and proper ventilation, you can reduce leakage by up to 35%, improving your home's energy efficiency and reducing the chance of moisture problems. The Department of Energy reports that after improper HVAC unit sizing, duct leakage is the single highest cause of inefficient heating and cooling. A national study revealed that one third of conditioned air is leaked into the attic, crawl space, and other areas outside the building envelope. Duct leakage allows conditioned air to escape. This escaping air causes the supply air flow to be less than the return air flow creating what's known as negative pressure. Negative pressure also allows for air and moisture to enter the building through cracks and crevices, resulting in even greater energy efficiency loss. During an initial Home Performance Assessment, we measure your home’s performance and energy efficiency with diagnostic equipment. Homeowners can learn where leakage is occurring by observe this process. We then provide a scientifically-based analysis, including recommendations for improvements that will improve your comfort and enable you to significantly reduce your electric bills through home energy efficiency measures. Combined with proper whole house sealing and ventilation, adding insulation to exterior walls and attics significantly increases the energy efficiency of your home.
