Advanced Energy Performance

Home / Requirements / Advanced Energy Performance


California Advanced Homes Program (CAHP) Builders work with Title 24 consultants to model homes in comparison to the 2016 Title 24, which took effect in January 2017. Title 24 consultants must possess either a 2013 or 2016 California Certified Energy Analyst (CEA) certificate.


The program evaluates homes based on a score called the Energy Design Rating (EDR). The closer a home’s EDR is to zero, the higher a home’s incentive. Homes must achieve the minimum CAHP EDR for their climate zone – 48 for coastal homes and 44 for inland homes.


Participants can lower their EDRs and raise their incentives by increasing the energy efficiency of their homes. Certain energy efficiency measures are eligible for additional incentive kickers (per home):

  • Designed for 2020 Zero Net Energy ($1,000)
  • Designed for 2020 Zero Net Energy Ready ($500)
  • DOE Zero Energy Ready Homes Participant ($400)
  • High Performance Attics/Ducts in Conditioned Space ($200)
  • High R-Value Walls ($200)
  • High Performance Fenestration ($200)
  • Balanced Indoor Air Quality System ($100)
  • Whole House Fan ($100)
  • Home Energy Management System (lower 2 EDR points)
  • 100% LED Lighting (lower 1 EDR point)

Please use the CAHP EDR Calculator to estimate the incentive for your home and learn more about incentive kickers.


The Program team reviews home plans, model files, and supporting documents to validate each home’s EDR score. Participants may not begin construction until receiving authorization from the Program.

Refer to the Program Handbook to see all requirements.
