HERS Ratings

With the Massachusetts energy codes getting stricter the process is becoming more difficult to get the code-required HERS score. Our team of RESNET Certified HERS Raters has over 25 years of experience in the industry and with more than 10,000 HERS ratings to our credit We know what it takes to help you achieve the highest HERS score you can for your construction project. We will work with you to identify any weak links at an early stage, and we provide support throughout the construction process.

WHAT IS A HER RATING?

HERS is the acronym for Home Energy Rating System, A HERS rating is an industry-standard to measure the efficiency of energy use in a home. It provides a comprehensive view of the house’s energy use, including performance testing of construction materials, and HVAC equipment including appliances, lighting, and other equipment. The HERS score is the most widely used method of proving compliance with local energy codes and when it comes to Stretch Code communities, a HERS rating is required (must have a score of 55 % or lower). An easy way to achieve energy code compliance starts with a HERS score and a great HERS Rater.

Her ratings can also qualify the home for advantages like energy incentive schemes, 2000 45L tax credits, or certifications like Passive House, ENERGY STAR, and LEED.

PERFORMANCE TESTING

Hers Rating

We conduct a series of tests on the systems in your home to determine their effectiveness. The tests include the blower door test, a vented test (if there is ductwork), and a ventilator test. These tests are non-invasive and will not cause disruption or damage to the home. The test results are fed into a HERS score software to help calculate the HERS score of the house.

BUILDING MATERIALS

A HERS score examines various building materials utilized within the home and assesses the impact each part has on the score of HERS. Insulation types, depth, and quality of installation are recorded to calculate the R-Value of the floors, walls and ceilings in the home. Windows have performance ratings to indicate the insulation percentage, U-Value, and how much solar energy radiates through the glass. This is known as solar energy gain (SHGC). Additional aspects, like the framing of walls or radiant barriers on roofs are also documented and entered into the HPERS software for rating.

HVAC

What utilities are available on your site? This question determines the kind of heating and cooling system you choose as part of your venture. We will track the type, size, fuel, and effectiveness of your heating and cooling system. Domestic hot water (DHW) systems are recorded to determine the efficiency as well as the fuel type and design of these systems. Distribution systems used for DHW have also been examined for features including pipe insulation and the total system length. Ventilation systems are checked to ensure compliance with applicable building codes.

APPLIANCES & LIGHTING

The efficiency and type of your appliance can influence the HERS rating you get. Certain appliances are classified as minimum rated elements, which are items that must be included in the HERS rating. These items are the refrigerator, dishwasher, range, washer, and dryer. You don’t need all of these the default settings can be set, but the majority of appliances sold in the present are more efficient than the default. Also, we will determine if your lighting is high-efficiency LED lighting, compact fluorescent, or incandescent.
