Why is it important for HERS raters to have knowledge of local building codes?

Understanding local building codes is crucial for HERS raters primarily because these codes outline the minimum requirements for energy efficiency that must be met in new constructions and renovations. By being knowledgeable about these codes, raters can assess whether a home complies with both state and local energy standards, which are often designed to promote energy efficiency, reduce environmental impact, and ensure safety.

When raters conduct energy audits, their evaluations will often be compared against these established codes, allowing for an accurate HERS rating, which influences how energy performance is quantified and reported. This ensures that homeowners are not only informed about their property's energy use but also that they are in compliance with governmental regulations, which can affect liability and taxes.

Knowledge of local building codes also helps raters guide builders and homeowners in making informed decisions about energy improvements and upgrades. By ensuring that homes meet the required energy efficiency standards and codes, HERS raters play a vital role in promoting sustainable building practices and contributing to overall energy savings in their communities.
