By Brianna Crandall, October 23, 2013—Hearings to finalize the 2015 International Energy Conservation Code (IECC) wrapped up in Atlantic City recently with big wins for higher efficiency requirements in existing buildings, controls for lighting and daylighting hardware and HVAC equipment specifications, according to a news release from the New Buildings Institute (NBI),
>The IECC is reviewed and updated every three years and serves as the model energy code for states and local jurisdictions across the country. The last version is the 2012 IECC.
In the United States, buildings account for about 40% of the energy consumed and 38% of all CO2 emissions, according to the U.S. Green Building Council. Cost-effective measures that cut the energy used by buildings represent a critical strategy to help building owners save money and curb the impacts of climate change, notes NBI.
“The updates related to existing and historic buildings clarify and further extend the code’s impact on the current building stock and will mean large energy savings growing over time,” said Jim Edelson, NBI senior manager of codes and policy. “Taken together, the approved code changes represent the most significant code revisions for energy consumption of existing buildings since the 1970s.”<
