Requirements & Incentives


RAHP utilizes the Energy Design Rating (EDR) to determine program eligibility. Of the multiple EDRs generated by the Title 24 modeling software, RAHP utilizes the Delta EDR — the difference between the Standard Efficiency EDR and Proposed Efficiency EDR  to calculate program eligibility.

Incentives are specific to the plan type and orientation of each lot. The estimated incentives rise incrementally with the performance of the building.


In order to qualify for RAHP, lots must demonstrate positive kWh savings. In CBECC-Res, kWh savings can be found by going to “Tools,” selecting “Review Analysis Results,” and subtracting the Total Proposed kWh usage from the Total Standard kWh usage. In EnergyPro 7, the total proposed and standard kWh usages can be found by generating an ECON-1 report in the reports section, and kWh savings can be determined using the method described previously.


RAHP offers escalating core incentives starting at $350 per lot for 2.0 Delta EDR  and positive kWh savings. Projects must include whole-home pre-wire, install smart thermostats, and install ENERGY STAR appliances. As the Delta EDR increases, so does the incentive amount. Each additional 0.1 Delta EDR results in a supplementary incentive. Once a project reaches a Delta EDR of 4.4, each additional 0.1 Delta EDR increases the total incentive even more.



Additionally, bonus measures are available to achieve higher incentives.
