Research supports need for program

SRP conducted one-on-one interviews with Phoenix-area homebuilders to obtain feedback to refine the SRP PowerWise Homes program prior to its introduction to the market. Overall, a majority of the homebuilders supported the program, especially being linked to SRP and the "energy-efficient home" certification to support the image of a quality-built home. Research also shows that consumers desired a home energy-efficiency program that is sponsored by a utility.

Energy-efficient homes are more than just a trend. Industry analysts predict that in the near future more than 2 million homes will earn an energy-efficiency rating similar to PowerWise Homes models.

According to a study by McGraw-Hill Construction, 20% of new construction will be green by 2012.

Get up to $1,150 per home with SRP PowerWise Homes

By participating in the SRP PowerWise Homes™ program, you'll offer discerning buyers the right combination of value, aesthetics, environmental sensibility and energy efficiency — and put money back in your pocket for each home you build. SRP PowerWise Homes

Incentives and benefits

For each SRP PowerWise Home you build, you'll earn $450–$1,150 based on the Home Energy Rating System (HERS) Index of the home. SRP PowerWise Homes must have a HERS Index of 84 or lower. This index uses an evaluation of house design in comparison with a computer-simulated reference house of identical size and shape.

There are three tiers of incentives based on the HERS Index:

Tier Rating Incentive
1 HERS Index of 84–78 $450/home
2 HERS Index of 77–71 $800/home
HERS Index of 70 or less $1,150/home

¹Additional water-efficiency requirements apply.

Verification of whole-house mechanical ventilation and pressure balancing of each room are required. (Note: Powder and laundry rooms are exempt from pressure balancing.)

Testing and inspections: To demonstrate the energy efficiency of the models being offered to buyers, testing and inspections are performed by a third-party consultant on randomly selected houses during construction. Compliance with the ENERGY STAR version 2 Thermal Bypass Checklist will be required as part of the testing and inspection process. SRP pays 100% of the cost for this initial testing.

About the program

The SRP PowerWise Homes program uses whole-building design to develop high-performance buildings at optimal costs. This approach brings together building design, energy conservation, and today's energy-efficient technologies to minimize a building's operating costs and make the most of all its elements.

Criteria established for PowerWise Homes are built on reduced energy consumption on a basis of kilowatt-hours per square foot, thereby lowering utility bills. Compared with standard homes, PowerWise Homes use substantially less energy for heating, cooling and water heating, delivering hundreds of dollars of annual utility-bill savings to each home.
