November 2, 2010—Local and state building code officials last week approved a package of revisions to the commercial section of the 2012 International Energy Conservation Code (IECC) that represent the largest single- step efficiency increase in the history of the national, model energy. The changes mean that new and renovated buildings constructed in jurisdictions that follow the 2012 IECC will use 30 percent less energy than those built to current standards.
Attendees voted nearly unanimously on a series of proposals to effect the change at the International Code Council’s (ICC) final action hearings held in Charlotte, North Carolina, October 27-31, 2010. The improvements were part of a major comprehensive proposal submitted jointly by New Buildings Institute (NBI), The American Institute of Architects (AIA), and the U.S. Department of Energy (DOE) that addresses measures such as cooling, lighting, quality assurance and renewable energy standards. Several other key proposals that contribute to the savings were approved independently.
The comprehensive proposal is largely based on NBI’s Core Performance protocol, a direct approach to achieving energy savings in commercial buildings. Utilities and public benefits administrators in six states and two Canadian provinces have adopted Core Performance as part of their voluntary efficiency program offerings.
“Increasing the efficiency of commercial building energy codes provides the best opportunity to bring about significant savings and helps move us along the path toward low-energy commercial buildings,” said Dave Hewitt, NBI executive director.
“The often contentious process of developing codes was largely avoided in this case because of the extensive outreach and collaboration that was undertaken to gain industry support for the proposals. As a result, we were able to successfully resolve differences prior to the hearings and put forward our best option for consideration,” Hewitt said.
“The overwhelming support we saw during the votes tells us the marketplace is ready for these practical, feasible and affordable improvements,” said Jessyca Henderson, AIA, director of sustainability advocacy at the AIA. “The nation’s code officials are to be commended and congratulated for seizing this historic opportunity to move the country toward more efficient buildings and help us build an economy that is less reliant on fossil fuels—now and into the future,” she said.
Computer modeling of the 2012 IECC shows more than 30 percent better energy efficiency on average than the ASHRAE 90.1-2004 model code, and payback periods on the new code measures are estimated at less than seven years depending on climate and building type. The energy savings in the 2012 IECC meet national calls from Congress, the Secretary of Energy and industry leaders to improve the efficiency of commercial buildings by 30 percent. In addition, the 2012 IECC will serve as the baseline standard for the International Green Construction Code (IGCC) currently under development.
The 2012 IECC contains many important, first-ever technical features including a new section on commissioning, pathways to use daylighting, and options for the use of on-site renewable energy. It will be published in April 2011 for adoption by state and local agencies.
