2013 Building Energy Efficiency Standards
Approved Computer Compliance Programs

The California Energy Commission (Energy Commission) has approved the following energy analysis computer programs that includes all Alternative Calculation Methods approved for the 2013 Building Energy Efficiency Standards (2013 Energy Standards) in accordance with the California Code of Regulations: Title 24, Part 1, Article 1, Section 10-109.

The individual programs are listed below under specific categories. These are the only programs authorized to be used under the performance approach (energy budget) method of compliance for the 2013 Energy Standards.

While the Energy Commission continues to improve software functionality, there are three residential software issues where work-arounds have been established for users of the computer compliance programs, and for building departments to verify energy projects. The only Energy Commission-approved work-arounds may be viewed here. When permanent solutions to these issues have been established and tested, the work-arounds will no longer be allowed and information will be distributed to users.

Note: Price listings of proprietary programs are available from the vendors at addresses and telephone numbers listed.
