California Adopts 2022 Energy Code

On August 11, the California Energy Commission adopted the state’s 2022 Energy Code, which includes stepped-up energy efficiency standards for newly constructed homes and buildings, as well as for substantially renovated existing structures. If approved by the California Building Standards Commission when it meets in December, the update would go into effect on Jan. 1, 2023, giving builders, contractors and other interested parties a year to gear up for the changes. 

For residential homes, the 2022 Energy Code would encourage builders to install heat pumps over gas-fueled HVAC units by establishing energy budgets based on efficient heat pumps for space or water heating. The updated code would also require homes to be “electric-ready” with dedicated 240V receptacles and space, in case homeowners later choose to replace installed gas appliances with electric appliances.

Additionally, the code would increase minimum kitchen ventilation requirements for fans over cooktops and would allow for exceptions to existing solar photovoltaic (PV) standards when sufficient roof area is not available, such as on top of smaller homes.

For buildings, the code would establish combined solar PV and battery standards for select businesses. Systems would be sized to maximize use of solar energy and avoid electricity demand during times when the grid must use gas-powered plants. In addition, the code would improve efficiency standards for building envelope, various internal systems and grid integration equipment, such as demand-responsive controls to buoy grid stability. The code would also establish new efficiency standards for commercial greenhouses, primarily those that grow cannabis.

Over the next three decades, the code is estimated to provide $1.5 billion in consumer benefits and reduce 10 million metric tons of greenhouse gas emissions, equivalent to taking nearly 2.2 million cars off the road for a year, according to the California Energy Commission. Moreover, expanded adoption of new energy-efficient technologies would help reduce costs of the technology over time.
