ENERGY DESIGN RATING
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 $200 per lot for 2.0 Delta EDR and positive kWh savings. The program provides incentive increments with every 0.1 increase in the Delta EDR score. Incentives ramp up more rapidly once the delta EDR hits a score of 6.0. Additionally, bonuses are available to assist with program eligibility as well as achieving higher incentives.
