Buildings in the United States are responsible for 39% of CO2 emissions, 40% of energy consumption, 13% water consumption and 15% of GDP per year, making green building a source of significant economic and environmental opportunity. Greater building efficiency can meet 85% of future U.S. demand for energy, and a national commitment to green building has the potential to generate 2.5 million American jobs.

CAL Green - California Building Standards Code

The California Building Standards Commission has announced the adoption of the 2013 California Building Standards Code. This includes the 2013 version of the California Green Building Standards Code (CALGreen). The new code will be published on July 1, 2013 and the public will be given 180 days to review the code before it goes into effect on January 1, 2014. This schedule reflects the state’s triennial code adoption and publication process. Updates are issued during an eighteen month intervening cycle.

CAL Green - California Green Building Standards CodeThe code is Part 11 of the California Building Standards Code in Title 24 of the California Code of Regulations and is also known as the CALGreen Code. In short, the code is established to reduce construction waste, make buildings more efficient in the use of materials and energy, and reduce environmental impact during and after construction.


There are a number of important updates in the 2013 code, such as:

  • An extensive update of California`s Energy Code
  • Division of the State Architect`s adoption of the 2010 Americans with Disabilities Act standards with California amendments
  • Updated California Green Building Code-CALGreen-requirements for nonresidential building alterations and additions
  • New plumbing code provisions pertaining to grey water and rainwater catchments

California Code of Regulations (CCR), Title 24, also known as the California Building Standards Code, is a compilation of three types of building criteria from three different origins:

  • Building standards that have been adopted by state agencies without change from building standards contained in national model codes;
  • Building standards that have been adopted and adapted from the national model code standards to meet California conditions; and
  • Building standards, authorized by the California legislature, that constitute extensive additions not covered by the model codes that have been adopted to address particular California concerns

Notwithstanding, the national model code standards adopted into Title 24 apply to all occupants in California except for modifications adopted by state agencies and local governing bodies. To learn more go to Guide to Title 24.

Starting in 1989, the BSC has published triennial editions of Title 24 in their entirety every three years.
