New energy code offers boosted efficiency
The 2009 edition of the International Energy Conservation Code reportedly offers 15% greater energy efficiency than the 2006 version.
The International Code Council (ICC) has released the 2009 edition of the International Energy Conservation Code (IECC), the national model energy code of choice for states, cities, and counties that adopt codes
The IECC—tied to federal law determined by Congress and the U.S. Dept. of Energy through the Energy Policy Act of 1992—is the only energy code that serves as the basis for federal tax credits for energy-efficient homes, energy efficiency standards for federal residential buildings and manufactured housing, and state energy code determinations.
According to the DOE, the 2009 IECC will produce approximately 15% in energy efficiency gains compared to the 2006 edition. New provisions in the 2009 code include improved window and skylight efficiencies, high-efficiency light fixtures in new homes, and radiant heat in unenclosed public spaces.
