Adhering to Delaware’s Green for Green program specifications results in homes being built to more energy-efficient levels than the 2009 IECC levels. Specifically: • Certifying at the Silver Performance Level for the ICC 700 standard using either the Prescriptive or Performance Paths will result in a residential building that is more efficient than if the building only complied with the 2009 IECC. • Certifying at the Silver level under LEED for Homes standard, including mandatory compliance with ENERGY STAR 2006 and earning two additional energy points will result in a residential building that is more efficient than if the building only complied with the 2009 IECC.
