Complete Energy Star thermal bypass inspection
Air leaks waste a lot of energy.
Air leaks not only mean significant heat loss, but they also can let moisture into the house. Years of testing and field experience indicate that many houses share design or building flaws that allow heat to enter or leave the building and increase the cost of heating and cooling. The EPA's Energy StarLabeling system sponsored by the Environmental Protection Agency and the US Department of Energy for labeling the most energy-efficient products on the market; applies to a wide range of products, from computers and office equipment to refrigerators and air conditioners. program calls these "thermal bypasses," and has compiled a list of the most common ones into a thermal bypass checklist. Using the checklist can help you get the most bang for your air-sealing buck.
