Comparison of the National Green Building Standard (ICC 700-2008) and LEED for Homes to the Residential Provisions of the 2009 IECC for the Delaware Green for Green Program

Abstract

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.
