Single Family Passive House Prescriptive Pathway

Measure Description

The purpose of this measure is to investigate and develop an alternative prescriptive compliance path for homes certified by Passive House (PH). The California Energy Commission and the Title 24, Part 6 Standards embrace many of the goals behind the Passive House Standard. That means optimized envelopes utilizing smaller heating, cooling and generation systems, and minimizing building energy use 

The guiding principles behind the PH Standard and Certification embrace the ongoing goals and intent of Title 24, Part 6. The intent of this research measure is to determine if buildings built to the PH Standard could potentially satisfy requirements under the 2022 California Energy Code, and could buildings certified under the PH Standard qualify as equivalent to the prescriptive requirements for residential buildings.  

The Statewide CASE Team will investigate whether any barriers or challenges exist to ensure enforceability, identify whether a home built to the Passive House Standard can meet the prescriptive code requirements, what, if any, measures may be required to meet equivalency, and review key elements in Passive House that are not adequately addressed in the ACM. 

While PH certified projects can comply with Title 24, Part 6 using the performance approach, providing a prescriptive compliance path for PH certified projects can allow for higher adoption in both single family and multifamily construction, which can further reduce energy use in buildings resulting in significant energy savings and greenhouse gas (GHG) reductions.
