CAHP Master Builder
The California Advanced Homes Program Master Builder initiative is an extension of the California Advanced Homes Program (CAHP) and is designed to support the early adoption of high performance building components.
Master Builder provides additional incentives for builders electing advanced design and construction of high performance fenestration. Additional participation benefits include:
- Increased CAHP incentives for each participating lot
- Exclusive consulting services from dedicated subject matter experts to guide projects from design to construction, including coordination of design meetings
- On-site training for design teams and subcontractors, installation guidance from product manufacturers, and coordination with the Workforce Instruction in Standards and Efficiency (WISE) program
Participant builder projects will be part of a statewide case study report that documents valuable lessons learned from adopting specified measures.

HIGH PERFORMANCE FENESTRATION
Master Builder HPF is open to both single family builders and multifamily developers. Single family projects must install HPF in a minimum of 10 homes, while multifamily projects must install HPF in a minimum of one building per property. All projects must complete HPF installation by December 1, 2019. Master Builder HPF participant can earn up to $15,000 in incentives for single family projects and up to $20,000 for multifamily projects.
Master Builder defines HPF as less than or equal to a 0.21 U-Factor in all climate zones, and less than or equal to a 0.23 SHGC in climate zones 2, 4, 6-15 (2019 SHGC prescriptive code requirement) where Title 24 code dictates a SHGC limit. The program has selected a U-Factor of 0.21 because this U-factor is typically achieved with triple-pane windows. Participating projects shall install HPF for all primary windows including casement, slider, hung, picture, and bay windows. The program will exempt skylights, garden windows, French doors, sliding glass doors, or any door with a glazed area of more than one half of the door area. The program may also exempt specialty non-standard window sizes and types on a case by case basis if those windows cannot be sourced to meet the program’s HPF thermal specifications. In addition, projects shall meet the prescriptive code requirement that the glazing area be less than or equal to 20 percent of total conditioned floor are area, and that west-facing glazing be less than 5 percent of conditioned floor area.
CAHP provides an incentive kicker of $200 per lot for high performance fenestration, and the windows’ increased efficiency will raise participants’ Delta EDRs and increase CAHP incentives.
Past Master Builder initiatives (CAHP performance kickers are current):
HIGH PERFORMANCE ATTICS
High performance attics minimize the temperature difference between the attic space and the conditioned air that travels through the attic ductwork. This reduced temperature difference lowers energy use for cooling and heating.
CAHP provides an incentive kicker of $200 per lot for high performance attics, and the attics’ increased efficiency will raise participants’ Delta EDRs and increase CAHP incentives.
HIGH PERFORMANCE WALLS
High performance walls minimize thermal bridging and reduce air leakage. This helps to maintain air temperature within the conditioned space, which reduces HVAC system demands and building energy use. The most common current high performance wall design options include 2×6 framing, either 16 inch on center or 24 inch on center, with a combination of cavity insulation and external continuous insulation.
