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 a 2016 California Certified Energy Analyst (CEA) certificate.


The program evaluates homes based on a score called the Delta Energy Design Rating (EDR). The entry level is a Delta EDR of 3 – as the score increases, so do the incentives.

To calculate your project’s Delta EDR, you must subtract the Standard Efficiency EDR (formerly Design) from the Proposed Efficiency EDR (formerly Design), then add any kicker points that apply.

The easiest place to grab the information needed to determine your Delta EDR score is on the CF-1R report.

Please view our orientation webinar for more information, or contact a TRC representative.


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):

  • 2019 Code Home ($500)
  • 2019 Code Ready ($250)
  • 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 (increase 0.5 EDR point inland / increase 1 EDR point coastal)
  • 100% LED Lighting (increase 0.5 EDR point inland / increase 1 EDR point coastal)

Please use the Delta 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 Delta EDR score. Participants may not begin construction until receiving authorization from the Program.

Refer to the Program Handbook to see all requirements.
