CEC Approves 2022 CALGreen Building Standards Code — to Improve Buildings and Advance State’s Climate Goals




Sacramento—The California Energy Commission (CEC) has approved the latest version of CALGreen, setting the stage for the California Building Standards Commission (CBSC) to adopt it as part of Title 24the Building Standards Code 

During the CEC’s September 30 business meeting, several groups, including the Natural Resources Defense Council (NRDC) and the Sierra Club voiced support for the action

 

The first CALGreen code was developed by the CBSC and other state agencies in 2007 in response to California’s Assembly Bill 32 that mandated greenhouse gas (GHG) emissions be reduced to 1990 levels by the year 2020. California met that goal, and CALGreen continues today to help decarbonize the state’s second-largest producer of GHGs—buildings.  


CALGreen is a mandatory green building code with additional voluntary provisions. Many local jurisdictions choose to adopt those provisions because those are more resource-efficient and environmentally friendly than state-mandated building codesBut  CALGreen doesn’t outpace the rest of California’s building code for long: after a couple of years of real-world testingthe voluntary provisions lay the groundwork for mandatory requirements for the next statewide building code. 


CALGreen goes through an update and approval process by the CEC every three years, but it’s not the only part of Title 24 that does this. The 2022 update of Part 6, known as the Energy Code, was approved in the CEC’s August business meeting. Both Energy Code and CALGreen are scheduled to go before the CBSC in mid-December 2021. If they are approved, they would be published in 2022 and go into effect on January 1, 2023, to give builders, contractors, and other interested parties a year to gear up for the changes. 


CEC Commissioner J. Andrew McAllister said  will help CALGreen California pivot more deeply toward the path of clean, low-carbon technologies “where things will be going in the future.” Electrifying buildings is critical to helping the state meet its long-term climate and carbon neutrality goalswhich is why CALGreen has provisions for including home battery storage for solar and heat pumps for space and water heating.  

 

Why California Needs Codes “Beyond The Building Code” 
CALGreen improves public health, safety, and general welfare through enhanced design and sustainable construction of buildings while conserving natural resources. Adopting all of CALGreen's 2022 standards will save more energy and reduce GHGs further than current mandates. GHGs could be reduced on average by 0.2 metric tons per building, per yearcompared to the mandatory Energy CodeThat’s like having 2,600 fewer cars on the road for the first year, according to the CEC. 


The total impact of the carbon dioxide emissions from the 2022 Energy Code and CALGreen updates equals sidelining 8,000 cars for the first year, and 24,000 cars by the third year. 


When municipalities want to build greener, more sustainable buildings than the building code requires, they can adopt all or part of CALGreen's package of pre-analyzed measures for their own reach codesBuildersdesigners, and other construction industry stakeholders then see these measures operating in the real world. This helps to encourage their use and expands the market for manufacturers and service providers of emerging technologiesCollectively, it reduces the costs of energy efficiency and building decarbonization for consumersIn this way  CALGreensignals the future direction of the Energy Code. 

 

How Climate Goals Become Building Standards  
 CALGreen covers a number of fields, with regulations encompassing energy efficiency, water conservation, sustainable building materials, site design, and air quality. That means a number of state agencies are involved in creating CALGreen and its updates, including 


  • The CEC (energy efficiency standards)

  • The California Department of Housing and Community Development (construction standards for homes)

  • The Building Standards Commission (nonresidential buildings standards), and

  • The California Division of the State Architect (school construction and access compliance standards)


As part of the development process, interested parties such as builders and environmental groups submit recommendations to the state agencies drafting  CALGreen standardsEach agency has a public outreach process to develop standards that they submit to the CBSC for approval.  


The 2022  CALGreen update simplifies the code and its application in several ways. It offers new voluntary prerequisites for builders to choose from, such as battery storage system controls and heat pump space, and water heating, to encourage building electrification.
