Status of State Energy Codes

Code Analysis & Development Activity

DOE encourages using new technologies and better building practices to improve energy efficiency. The Building Energy Codes Program works with the ICC, ASHRAE, IESNA, American Institute of Architects (AIA), the building industry, and state and local officials to develop and promote 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.

DOE Code Comparison — DOE has prepared a Comparison of Standard 90.1-07 and the 2009 IECC with Respect to Commercial Buildings. This comparison is available to states who may wish to understand the differences between Standard 90.1-2007 and the 2009 IECC.

DOE has also prepared a series of Nationwide Analysis Reports that examine the impacts of the 2009 IECC for residential buildings and the impacts of Standard 90.1-2007 for commercial buildings at the state level.
