Alliance To Save Energy Hails 25-30% Advance In 2012 Energy Code For New and Renovated Residential, Commercial Buildings

Washington, D.C., July 28, 2011 — The Alliance to Save Energy today hailed a newly-released model building energy code upgrade that will improve energy use in commercial and residential buildings in the United States by as much as 30%.

The landmark 30% improvement for new and renovated residential buildings is included in the 2012 International Energy Conservation Code (IECC), which also would increase the energy efficiency of commercial buildings by about 25% when compared to the 2006 version of the code.

The historic increase in the code was advocated by the Energy Efficiency Codes Coalition (EECC), a group led by the Alliance and comprised of a diverse group of policy makers, businesses and public interest groups. The improvements in the model code will have far-reaching impact as nearly all states operate under a version of the IECC, which is the only model residential energy code referenced in federal statutes.

“The significant advances in energy codes for new U.S. construction have multiple benefits even beyond the noteworthy savings of energy, money and pollutant emissions that they will achieve,” said Alliance President Kateri Callahan.

“The 2012 code will reduce peak energy demand, thereby reducing strain on the electric grid and increasing its reliability; reduce the size and cost of heating and cooling equipment in residential and commercial buildings; improve indoor comfort; help stabilize local energy prices; and increase national energy security,” she added.

“We commend the International Code Council for its historic accomplishment and the Energy Efficient Codes Coalition for its persistence in advocating for a substantial code improvement,” Callahan continued. “We urge each of the 50 states to fulfill the promise of the 2012 code by adopting it promptly and enforcing it strictly in the months and years ahead.”

The Alliance has estimated that if all states were to adopt the strengthened code next year and achieved full compliance by 2013 – an admittedly ambitious scenario – the annual savings by 2030 would come to:

  • At least $40 billion in energy costs to consumers and businesses;
  • More than 3.5 quadrillion Btu of energy annually – about 9 percent of current building energy use; and
  • About 200 million metric tons of CO2 emissions.

The EECC says all states have committed to 90% compliance with the 2012 IECC by 2017. For homes, improvements will:

  • Ensure that new homes are better sealed to reduce heating and cooling losses;
  • Improve the efficiency of windows and skylights;
  • Increase insulation in ceilings, walls and foundations;
  • Reduce wasted energy from leaky heating and cooling ducts;
  • Improve hot-water distribution systems to reduce wasted energy and water in piping; and
  • Boost indoor and outdoor lighting efficiency.

Commercial building gains in the 2012 IECC include:

  • Improved insulation and windows;
  • Continuous air barriers – sealing of all outside surfaces to keep heated and cooled air inside and prevent outside air from leaking in;
  • Daylighting controls; and
  • Increased use of economizers, which use outdoor air for cooling when possible, rather than mechanical air conditioning.


The Alliance to Save Energy is a coalition of prominent business, government, environmental and consumer leaders who promote the efficient and clean use of energy worldwide to benefit consumers, the environment, the economy and national security.
