Which organization looks after the HERS industry and Rater accreditation?

The Residential Energy Services Network (RESNET) is the organization responsible for overseeing the HERS industry and Rater accreditation. RESNET provides guidelines and standards that ensure energy efficiency ratings for homes are accurate and consistent. This includes training and certifying raters who conduct energy audits and assessments, ensuring they adhere to established protocols. By managing these standards, RESNET plays a crucial role in promoting energy efficiency in the residential building sector.

The other choices represent important organizations within the broader context of energy efficiency and building standards but do not specifically oversee HERS raters or their accreditation. For example, the National Association of Home Builders primarily focuses on the interests of home builders and developers, while the U.S. Department of Energy supports energy conservation initiatives and policies, and Energy Star Program, which promotes energy-efficient products, functions independently from the HERS rating system.
