Evidence in most states suggests that non-compliance with building energy codes has eroded their potential energy-saving benefits. IMT estimates the savings from bringing just a year’s worth of new residential and commercial construction in the U.S. up to full compliance could reach $189 million. This equates to lifetime savings of up to $37.1 billion for just five years' worth of new buildings.
Click on each state for an estimate of the potential energy and dollar savings from improving compliance with building energy codes. The low case corresponds to a 25% improvement in the rate of energy code compliance; the high case corresponds to a 75% improvement.
