Step 6: Home Energy Rater

Which path will your project pursue?

Homes may earn the ENERGY STAR using the following ENERGY STAR Prescriptive Path or Performance Path in all states except those for which regional program requirements have been developed. See EPA’s Web site for the latest list. Note: Currently, North Carolina does not have regional program requirements.

Compare your project to the chart below. If your conditioned floor area (CFA) is greater than the limit based on number of bedrooms, the project must pursue the Performance Path.

Bedrooms 1 2 3 4 5 6 7 8
CFA 1,000 1,600 2,200 2,800 3,400 4,000 4,600 5,400
ENERGY STAR Prescriptive Path

The Prescriptive Path provides a single set of measures that can be used to construct an ENERGY STAR qualified home. Modeling is not required; however, no tradeoffs are allowed. Using a Rater, verify that all requirements have been met in accordance with the Mandatory Requirements for All Qualified Homes and with RESNET’s On-Site Inspection Procedures for Minimum Rated Features.

ENERGY STAR Performance Path

The Performance Path provides flexibility to select a custom combination of measures for each home that is equivalent in performance to the minimum requirements of the ENERGY STAR Reference Design Home. Equivalent performance is assessed through energy modeling. Using a Rater, verify that all requirements have been met in accordance with the Mandatory Requirements for All Qualified Homes and with RESNET’s On-Site Inspection Procedures for Minimum Rated Features.

First, determine the ENERGY STAR HERS Index Target. Some energy modeling programs will automatically calculate the HERS Target Index based on inputs, and you, as a Rater, will not need to use the document listed below. Follow the link below for a detailed approach of calculating this target:

Second, select measures to meet the performance targets. It is important to note:

  • Regardless of the measures selected, all applicable items on all four ENERGY STAR Inspection Checklists must be completed.
  • On-site power generation may only be used to meet the ENERGY STAR HERS Index Target for homes that are larger than the Benchmark Home and only for the change in ENERGY STAR HERS Index Target caused by the Size Adjustment Factor.
