Code Analysis and Development
The U.S. Department of Energy (DOE) strives to improve energy efficiency by encouraging the use of new technologies and better building practices. DOE's Building Energy Codes Program (BECP) works with federal agencies, national code organizations, the building industry, and state and local officials to promote more stringent building energy codes.
BECP works closely with the ICC, ASHRAE, IESNA, American Institute of Architects (AIA), and other code user groups to develop more stringent and easy-to-understand building energy codes and to assess potential code barriers to new energy-efficient technologies.
Code Analysis
DOE Code Determinations
The Energy Policy and Conservation Act (EPCA, 42 USC 6833) establishes a role for the DOE to determine whether revisions to the Model Energy Code (succeeded by the IECC) or the ASHRAE/IES Standard 90.1 would improve energy efficiency in residential and commercial buildings, respectively.
