The Building Energy Efficiency Standards (Standards) were first adopted and put into effect in 1978 and
have been updated periodically in the intervening years. The Standards are a unique California asset and
have benefitted from the conscientious involvement and enduring commitment to the public good of many
persons and organizations along the way. The 2013 Standards development and adoption process
continued that long-standing practice of maintaining the Standards with technical rigor, challenging but
achievable design and construction practices, public engagement and full consideration of the views of
stakeholders.
The 2013 Standards revision and the supporting documents were conceptualized, evaluated and justified
through the excellent work of Energy Commission staff and consultants working under contract to the
Energy Commission, Pacific Gas and Electric Company, Southern California Edison Company, San Diego
Gas and Electric Company, and Southern California Gas Company. At the Energy Commission, Maziar
Shirakh, P.E.; and Martha Brook, P.E. served as the project managers and senior engineers. Bill
Pennington, Deputy Division Chief of the Efficiency and Renewable Energy Division, provided overall
guidance to the staff and consultants. Eurlyne Geiszler served as the Office Manager for the High
Performance Buildings Office. Pippin Brehler and Kristen Driskell provided legal counsel to the staff. This
document was created with the technical assistance from Martha Brook, PE, Sabaratnam Thamilseran,
PE, David Ware; Nelson Pena, Rob Hudler; and Owen Howlett. Other key technical staff contributors
included, Gary Flamm; Patrick Saxton P.E.; Jeff Miller, P.E.; Payam Bozorgchami, P.E.; Tav Commins;
and Mark Alatorre. Additional staff input and assistance came from Ron Yasny; the Energy Hotline staff;
and the Energy Commission’s Web Team. Critical support for the staff in conceptualizing, evaluating, and
reviewing this document came from Architectural Energy Corporation, L’Monte Information Services, Gard
Analytics, National Renewable Energy Laboratory, Hitchcock consulting, 360 Analytics, Wrightsoft
Corporation, Taylor Engineering, McHugh Energy, Gabel Associates, Energy Solutions, E3, PECI, and
the Heschong Mahone Group.
The authors are grateful to the many people and organizations that contributed to the development and
production of the Standards and the supporting documents. The documents reflect, to a large extent, the
comments made by the many people who took time to carefully review earlier versions. Reviewers who
significantly contributed to the content include members of CABEC and CALBO. Special thanks go to
Panama Bartholomy, the former Deputy Director Efficiency and Renewable Energy Division for his vision
and support of the 2013 Standards.

The Energy Commission dedicates the adoption of the 2013 Building Energy Efficiency
Standards to Valerie T. Hall, (November 28, 1952 - December 21, 2010), Deputy Director of
the Efficiency and Renewable Energy Division for her more than 32 years of dedication to
excellence in the development and implementation of energy efficiency programs in
California with the most aggressive energy efficient building standards in the country and for
being a model for others to follow.
ABSTRACT

Public Resources Code Sections 25402 and 25402.1 were enacted in 1975 as part of the enabling 
legislation establishing the California Energy Commission and its basic mandates.  These 
sections require the Energy Commission to adopt, implement, and periodically update energy 
efficiency standards for both residential and nonresidential buildings.   

The Standards must be cost effective based on the life cycle of the building, must include 
performance and prescriptive compliance approaches, and must be periodically updated to 
account for technological improvements in efficiency technology.  Accordingly, the California 
Energy Commission has adopted and periodically updated the Standards (codified in Title 24, 
Part 6 of the California Code of Regulations) to ensure that building construction, system design 
and installation achieve energy efficiency and preserve outdoor and indoor environmental 
quality.  The Standards establish a minimum level of building energy efficiency.  A building can 
be designed to a higher efficiency level, resulting in additional energy savings. 

The 2013 Building Energy Efficiency Standards focus on several key areas to improve the 
energy efficiency of newly constructed buildings and additions and alterations to existing 
buildings, and include requirements that will enable both demand reductions during critical 
peak periods and future solar electric and thermal system installations.  The most significant 
efficiency improvements to the residential Standards are proposed for windows, envelope 
insulation and HVAC system testing.  The most significant efficiency improvements to the 
nonresidential Standards are proposed for lighting controls, windows, unitary HVAC 
equipment and building commissioning.  New efficiency requirements for process loads such as 
commercial refrigeration, data centers, kitchen exhaust systems and compressed air systems are 
included in the nonresidential Standards.  The 2013 Standards include expanded criteria for 
acceptance testing of mechanical and lighting systems, as well as new requirements for code 
compliance data to be collected in a California Energy Commission‐managed repository. 

The 2013 Standards also include updates to the energy efficiency divisions of the California 
Green Building Code Standards (Title 24, Part 11).  A set of prerequisites has been established 
for both the residential and nonresidential Reach Standards, which include efficiency measures 
that should be installed in any building project striving to meet advanced levels of energy 
efficiency.  The residential Reach Standards have also been updated to require additional 
energy efficiency or on‐site renewable electricity generation to meet a specific threshold of 
expected electricity use.  Both the residential and nonresidential Reach Standards include 
requirements for additions and alterations to existing buildings. 

Energy Commission staff estimates that the implementation of the 2013 Building Energy 
Efficiency Standards may reduce statewide annual electricity consumption by approximately 
613 gigawatt‐hours per year, electrical peak demand by 195 megawatts, and natural gas 
consumption by 10 million therms per year.  The potential effect of these energy savings to air 
quality may be a net reduction in the emission of nitric oxide by approximately 59 tons per year,
sulfur oxides by 2.4 tons per year, carbon monoxide by 41 tons per year and particulate matter 
less than 2.5 microns in diameter by 10 tons per year.  Additionally, Energy Commission staff 
estimates that the implementation of the 2013 Standards may reduce statewide carbon dioxide 
equivalent emissions by 215 thousand metric tons per year.    

Energy Commission staff have completed an analysis of the environmental impacts of the 
proposed 2013 Building Energy Efficiency Standards for residential and nonresidential 
buildings.  In addition to air emissions, issues of on‐site water use, indoor air pollution and 
changes in materials use including:  Mercury, Lead, Cooper, Steel, Plastic Silicon, Gold, 
Aluminum, Fiber Glass, Titanium, Glass and Wood were considered.  It is the opinion of Energy 
Commission staff that the potential environmental impacts that may be associated with the 
implementation of the 2013 Building Energy Efficiency Standards are less than significant.  
Therefore, Energy Commission staff recommends the adoption of a Negative Declaration for the 
2013 Building Energy Efficiency Standards.
