Title 42 › Chapter CHAPTER 81— - ENERGY CONSERVATION AND RESOURCE RENEWAL › Subchapter SUBCHAPTER II— - ENERGY CONSERVATION STANDARDS FOR NEW BUILDINGS › § 6834
The Secretary must write and update energy-efficiency rules for new federal buildings and major renovations. Within 2 years after October 24, 1992, the Secretary had to make standards that are technically possible and cost-effective, after talking with federal agencies and building groups, and those rules had to start no later than one year after they were issued. The standards must at least meet the 2004 International Energy Conservation Code for homes and ASHRAE Standard 90.1–2004 for commercial buildings, follow those codes’ formats when practical, and, after talking with the EPA, include measures about radon and other indoor air pollutants where appropriate. By one year after August 8, 2005, the Secretary had to set stronger standards that, when life-cycle cost-effective, require new federal buildings to use at least 30% less energy than the 2005 code levels and apply sustainable design. Water-saving technologies must be used when they help save energy and are life-cycle cost-effective, and solar hot water should meet at least 30% of hot water needs if cost-effective. After each future update to ASHRAE or the International Code, the Secretary must decide within a year whether to update federal standards. Agencies must list new federal buildings in their budgets and reports and say if they meet the standards. By one year after December 19, 2007, the Secretary had to set standards for certain larger projects to cut fossil-fuel energy versus similar 2003 buildings by these amounts: FY2010 55%, FY2015 65%, FY2020 80%, FY2025 90%, and FY2030 100%. The rules also require sustainable design, a chosen green building certification system with regular reviews, possible internal agency certification with spot external checks, and special rules for privatized military housing. The Secretary must review the standards at least every 5 years and update them if more savings are possible. Interim rules from before October 24, 1992 remain until replaced.
