RESNET Ratings provides a relative energy use index called the HERS® Index – a HERS Index of 100 represents the energy use of the “American Standard Building” and an Index of 0 (zero) indicates that the Proposed Building uses no net purchased energy (a Zero Energy Building). A set of rater recommendations for cost-effective improvements that can be achieved by the Rated Building is also produced.
RESNET standards encompass three areas:
- Software accreditation achieved by passing a battery of software verification tests developed by U.S. National Laboratories and RESNET
- Definition of knowledge base and skill sets that a rater must demonstrate through passing an online RESNET National Rater Test
- A quality assurance evaluation that features each Rating Provider employing a certified Quality Assurance Designee. The Quality Assurance Designee must annually independently verify internal consistency of a minimum 10% of all building input files and independently field verify the accuracy of a minimum of 1% of each certified Rater’s homes
