To earn the ENERGY STAR label, a home must meet guidelines for energy efficiency set by the U.S. Environmental Protection Agency (EPA). These homes are at least 20% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy saving features that typically make them 20–30% more efficient than standard homes. The home’s actual energy performance must be certified by an independent Home Energy Rater who is responsible for conducting onsite testing and inspections of installed measures such as insulation, high performance windows, building envelope, duct systems, and efficient heating and cooling equipment.
