The first step in weatherizing any home is to conduct a home energy audit. These "home energy checkups" help homeowners determine where their house is losing energy and decide what steps need to be taken in order to make the home more energy efficient.
750 thousand homes have been weatherized over the past three years through the Department's Weatherization Assistance Program, saving families $400 a year on their heating and cooling bills.
More than 750 thousand homes were weatherized by the Department’s Weatherization Assistance Program in the past three years. Secretary Chu spoke with governors and members of Congress around the country to celebrate this huge accomplishment -- which was finished ahead of schedule and is saving the average household $400 annually on their heating and cooling bills.
The unique internal construction of the gas-filled panels developed at the Lawrence Berkeley National Laboratory in California are as effective barriers to heat as its pink fibrous counterparts with less material in less space. To improve the panel’s thermal performance the panels can be inflated with compressed inert gas, like argon, xenon or krypton, which doesn’t heat as easily as air.
