Home Energy Rating System
(HERS) Ratings

At C2S Energy, we provide certified HERS Ratings to homeowners, builders, and
developers looking to meet code compliance, enhance energy performance, or
qualify for energy-efficient home programs.

What is a HERS Rating?

A HERS Rating is the industry standard for measuring a home’s energy efficiency.

Developed by RESNET, this nationally recognized system evaluates how much energy a home is expected to use and assigns it a HERS Index Score the lower the score, the more energy-efficient the home.

Our HERS Rating Process

Plans Review + Energy Modeling

Once we receive your plans, we will use software to create an energy model of your project to show how it will perform energy-wise.

Energy Consulting + Midpoint Inspection

We work with you to identify any weak links early on during the design stage and provide support throughout the entire construction process.

As your project nears completion, we will conduct our final inspection and perform a series of tests (blower door test, duct leakage test, and ventilation test).
