What must a HERS Rater do to deliver accurate energy rating results?

Utilizing RESNET accredited software tools is essential for HERS Raters to deliver accurate energy rating results because these tools are specifically designed to analyze the energy performance of a home based on standardized measurement criteria and protocols. RESNET stands for the Residential Energy Services Network, and the accredited software tools incorporate energy modeling programs that follow compliance with regulations and standards set forth by RESNET.

These tools allow Raters to input precise data about the home’s construction, insulation, HVAC systems, and other energy-related features. They then perform calculations that help determine the home's energy efficiency rating. The use of accredited software ensures that the energy rating process is consistent, reliable, and aligned with industry standards, leading to actionable insights for homeowners and builders aiming to improve energy performance.

This reliance on validated software rather than personal judgment, estimates, or the subjective experiences of previous reports reinforces the integrity of the energy rating process, providing stakeholders with trustworthy energy performance evaluations.
