What is a key requirement for ensuring accurate HERS ratings?

Keeping current with frequently changing building codes is crucial for ensuring accurate HERS ratings because these codes establish the minimum energy efficiency requirements for buildings in a given jurisdiction. Building codes are updated regularly to reflect advancements in technology, evolving understanding of energy efficiency, and changes in environmental considerations.

HERS raters rely on these codes to assess whether a building meets the necessary criteria for energy performance and to provide an accurate rating. By staying informed about the latest codes, raters can ensure that their evaluations reflect the most current standards and practices, thereby providing reliable and relevant ratings. This commitment to ongoing education and awareness helps raters identify compliance issues and recommend appropriate energy efficiency improvements, ultimately guiding homeowners and builders towards more sustainable practices.
