Residential Code Development

The model residential building energy code is produced by the International Code Council (ICC). The ICC performs periodic revisions through a defined process that allows outside participation from stakeholders, including public and governmental entities. Once the revision process is completed, a new edition of the model code is published. States and local jurisdictions can then reference these codes, to legislate increased energy efficiency in residential buildings through their adoption processes. The process defined under Regulations and Rulemaking is used to develop building energy codes residential federal buildings and manufactured housing.

Support and Analysis

The U.S. Department of Energy (DOE) participates in the residential building codes and standards development process to foster increased efficiency in new and existing homes and low-rise residential buildings by incorporating cost-effective energy efficiency measures. In support of this goal, Pacific Northwest National Laboratory (PNNL) evaluates benefits associated with code changes.

• Methodology
• Economic Analysis
• Prototype Building Models

Both the International Energy Conservation Code (IECC) and Standard 90.2 are reviewed for opportunities to save energy. DOE then prepares and submits proposed changes with supporting documentation for consideration. DOE maintains membership on the ASHRAE 90.2 Standing Standards Project Committee and supports development through analysis of addenda. For IECC, DOE develops and submits proposed changes and supports those proposals through the public hearing process. More information on these processes may be found by visiting the ASHRAE or ICC websites.
