What is a non-residential HERS Rater and what do they do?

If you've ever wondered what a non-residential HERS Rater does, this blog post is for you. It will explain the role of a non-residential HERS Rater and how they can help make your commercial projects more energy efficient.

Why is a non-residential HERS rating important?

  • A HERS Rater can help you save money and energy, reduce environmental impact, increase tenant satisfaction, and increase property value.
  • The Energy Independence and Security Act of 2007 (EISA) requires that all new homes meet a minimum energy efficiency standard set by the Department of Energy's Office of Energy Efficiency & Renewable Energy (EERE). This standard is known as HERS Index Score – Residential (HERS-R), which has four ratings: Home Energy Rating System for new single-family homes; evaluation report for existing single-family homes; rating system for multifamily residential buildings; evaluation report for existing multifamily residential buildings.

What work does a HERS Rater do on a project?

The HERS Rater is an energy auditor that uses the Home Energy Rating System (HERS) to conduct a full-scale analysis of a building's energy consumption. The goal of this analysis is to determine if improvements can be made to increase efficiency, thus reducing utility bills and emissions.

The primary role of the HERS Rater is to test for air leakage and insulation problems in buildings undergoing construction or remodeling projects. The HERS Rater will use blower door tests for air leakage testing and infrared cameras for insulation assessment.

Do you have a commercial or multi-family project coming up and looking for a non-residential HERS Rater?

HERS Rater is a rating system that helps you measure the energy efficiency of your commercial or multi-family building. It will help you meet your state's energy code requirements and save on utility bills. HERS Raters can help you understand how much energy your building consumes, which in turn will help you qualify for green building certification. They can also assist in measuring the efficiency of individual components within the project, such as windows and insulation systems.

A HERS Rater can help you make your commercial projects more energy efficient.

A HERS Rater is a trained and certified professional who can help you determine the energy efficiency of your building. They look at all aspects of the building, including insulation, ductwork, and lighting. Because they look at everything that affects how much energy a building uses, they don’t just measure how much power it consumes when it’s turned on; instead, they evaluate its overall performance over time.

HERS Raters are trained to conduct comprehensive energy audits that include:

  • The results of previous audits
  • The current status of the property (e.g., whether or not there are any broken windows)
  • A complete list of potential improvements
  • A detailed plan for making those changes
