Implementing Passive House in Title 24 | California Bill Proposal

Climate Action California Needs Your Help – Together, we can make a difference!

Passive House California (PHCA) is backing the Climate Action California proposal to integrate the global Passive House construction standard into California’s Energy Building Code Title 24. This move would allow the Passive House Standard to be incorporated into the code as an alternative compliance pathway, enabling the establishment of an ambitious, climate-conscious reach code. This approach represents a key strategy for creating resilient, affordable housing for low-income communities while preparing for the future.
