HERS Ratings

We offer HERS Ratings (Home Energy Rating System Ratings) throughout the region. A Home Energy Rating is a requirement for many green building and energy efficient building standards, and is the nation's leading "miles-per-gallon" equivalent for homes.

The Residential Energy Services Network (RESNET) created the HERS Index to apply a uniform set of guidelines and standards through which a home’s energy efficiency and performance can be assessed. The index created by RESNET allows homes to be compared to industry standards and takes the ambiguity out of a home energy assessment.

We use the HERS index to help us provide an unbiased assessments of a home’s energy energy efficiency and performance. We can show you where your home stands and provide estimates on how certain changes or improvements to your home would impact your score.

What is a HERS Rating?

A HERS Rating essentially generates a report card for your home’s energy efficiency. It tells you how well your home is performing across all of it’s various systems and components, some of which include:

  • Exterior walls
  • Floors over unconditioned spaces
  • Ceilings and roofs
  • Attics, foundations and crawlspaces
  • Windows and doors, vents and ductwork
  • HVAC systems, water heating systems, and thermostats.

By identifying weaknesses and strengths in these spaces and systems, we can make suggestions for how to improve weak areas. Our suggestions range from easy fixes to in depth retrofits because we take the time to understand the root of performance problems and the inefficiency issues to which they contribute. Every little change helps, which is why we use HERS ratings to highlight performance improvement opportunities, whether they are big or small.

How does it work?

By using HERS guidelines, we are able to calculate a relative performance score for a home, which can be measured against the national average for efficiency. As the HERS index is nationally recognized, the US Department of Energy has released average benchmarks for home ratings within the index (If you’re curious--a standard new home is typically 100 and a re-sale home is typically 130. You can learn more about HERS scores here).

To generate these scores we use advanced testing and diagnostic equipment like blower doors, duct leakage testers, combustion analyzers and infrared cameras in order to evaluate the main parameters below:

  • The location of air leaks within the building envelope and the amount of leakage
  • HVAC distribution ducts’ level of leakiness
  • Ceiling and wall insulation effectiveness
  • Assessment of combustion safety issues

Data is collected on all of these parameters, plugged into the HERS rating simulation, and a HERS index score is determined.

While the score is an effective way to rate your home’s performance, we also provide a cost benefit analysis of each suggestion for improvement that we provide. The information is yours to use as you please--whether that’s showing a contractor what to work on or improving your home’s resale value.

What are the Benefits of a HERS Rating?

A HERS Rating is a requirement for many green building and energy efficient building standards across the country, including ENERGY STAR for Homes. A HERS Rating is also a requirement for an Energy Efficient Mortgage (EEM) and/or an Energy Improvement Mortgage (EIM). Further, it can be a great way for builders and realtors to set their homes apart in a crowded real estate market -- a good HERS score is an objective, measured representation of a home's energy efficiency. Much as miles-per-gallon fuel efficiency ratings for automobiles play an increasingly important role in car-buyers' decisions, a Home Energy Rating may soon play an equally important role in the homebuying process for homebuyers across the country.
