The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Summary:

Note: The California Energy Commission adopted the 2013 Building Energy Efficiency Standards for new residential and commercial construction on May 31, 2012. The new standards are expected to take effect on January 1, 2014, and represent significant energy and water savings compared to the current standards. Among many notable provisions, the new standards will require new homes and businesses to be built "solar ready", allowing for an easier installation of photovaltaic panels at a later time. The summary below represents the building code that is currently in place and will remain in place until 2014. Click here for more information about the 2013 Building Energy Efficiency Standards. 

Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

The California Building Standards Commission (BSC) is responsible for administering California's building standards adoption, publication, and implementation. Since 1989, the BSC has published triennial editions of the code, commonly referred to as Title 24, in its entirety every three years. On July 17, 2008 the BSC unanimously approved the nation's first statewide voluntary green building code. In January 2010, the BSC adopted a final version of the new building code, CALGreen, parts of which became mandatory on January 1, 2011. CALGreen exists alongside the latest edition of Title 24, which took effect on January 1, 2010. CALGreen includes provisions to ensure the reduction of water use by 20%, improve indoor air quality, divert 50% of new construction waste from landfills, and inspect energy systems (i.e. heat furnace, air conditioner, mechanical equipment) for nonresidential buildings over 10,000 square feet to make sure that they're working acording to design.

Title 24 applies to all buildings that are heated and/or mechanically cooled and are defined under the Uniform Building Code as A, B, E, H, N, R, or S occupancies, except registered historical buildings. Additions and renovations are also covered by the code. Institutional building's which include hospitals and prisons are not covered.

For residential low-rise buildings the current code provisions include compliance credits for high performance ducts and building envelope features. The size of credit depends on the action taken. For example simply designing ducts to Air Conditioner Contractor's Association guidelines or properly sealing duct joints provided lower levels of credit than having the HVAC system tested for duct leaks. To take credit for these measures the installer and inspector must be trained and certified.

Local governmental agencies can modify the state energy code to be more stringent when documentation is provided to the California Energy Commission.

AB 1103, passed in October 2007, requires annual energy-use reporting for all of California's nonresidential buildings effective January 2009. AB 531 of 2009 superseded AB 1103, and clarified that the CEC has the authority to set a schedule of compliance. The CEC decided through a rulemaking process to implement the law in stages based on building size. Starting on July 1, 2013, buildings of more than 50,000 square feet will need comply with the law. Smaller buildings will need to comply with the law by either January 1, 2014 or July 1, 2014, depending on size.
