Retrofit / Weatherization
According to the Building Performance Institute (BPI), America's existing housing needs help. Many of the 128 million homes in this country were constructed before modern energy and building codes were established. These homes often suffer from performance problems ranging from inflated energy consumption to poor thermal comfort to indoor air quality issues. For example, a drafty home, rooms that are too hot or too cold, and high energy bills are all common issues for homeowners. A quality installation of a new heating or air conditioning system, buying replacement windows, or adding more insulation may fix part of the problem. But the way to better results is through an integrated "whole-house" approach that looks at your house as a system.
