What is the primary goal of HERS raters in building energy modeling?

The primary goal of HERS raters in building energy modeling is to predict a home’s energy performance under various conditions. This focus on energy performance is critical because it allows for quantification and assessment of energy efficiency, which is essential for meeting energy codes, achieving certification, and informing homeowners about potential energy savings. By understanding how different factors influence energy use—such as insulation levels, HVAC systems, and window efficiency—HERS raters can provide insights that help improve a home’s overall energy performance. This information is invaluable for both builders aiming to create energy-efficient homes and for buyers seeking to understand the long-term energy costs associated with a property.

In contrast, factors like aesthetic appeal, structural integrity, or resale value, while important in the overall home-buying process, do not fall within the primary scope of the HERS rating system which is strictly focused on energy performance and efficiency.
