Public Resources Code Sections subdivisions a - b and For this reason, the Standards include both a prescriptive option, allowing builders to comply by using methods known to be efficient, and a performance option, allowing builders complete freedom in their designs provided the building achieves the same overall efficiency as an equivalent building using the prescriptive option.

Reference Appendices are adopted along with the Standards that contain data and other information that helps builders comply with the Standards.

The update to the Building Energy Efficiency Standards focuses on several key areas to improve the energy efficiency of newly constructed buildings and additions and alterations to existing buildings. The most significant efficiency improvements to the residential Standards include the introduction of photovoltaic into the prescriptive package, improvements for attics, walls, water heating, and lighting.

The Standards also include changes made throughout all of its sections to improve the clarity, consistency, and readability of the regulatory language. Public Resources Code Section The Alternative Calculation Method ACM Approval Manual adopted by regulation as an appendix of the Standards establishes requirements for input, output and calculational uniformity in the computer programs used to demonstrate compliance with the Standards.

From this, the Energy Commission develops and makes publicly available free, public domain building modeling software in order to enable compliance based on modeling of building efficiency and performance. The ACM Approval Manual also includes provisions for private firms seeking to develop compliance software for approval by the Energy Commission, which further encourages flexibility and innovation. The Standards are conceptually divided into three basic sets.

First, there is a basic set of mandatory requirements that apply to all buildings.
