With a team of eight RESNET Certified HERS Raters and two energy modelers, we're equipped to guide you through the energy code and to meet the required HERS Index Score. We analyze your plans and make recommendations on everything from windows and washer machines to mechanicals.

If you are building a single family house in a town or city that has adopted  the Stretch Energy Code then you need to hire a RESNET Certified HERS Rater to perform testing and energy modeling on your house.

New Homes, Renovations and Additions all must comply with varying provisions of the energy code. We help you navigate this process and make recommendations to keep you on time and on budget.

What we do: Duct Testing, Blower Door Testing, Insulation Inspection, Thermal Barrier Inspection and more

ENERGY STAR certification shows buyers that you've met strict energy code requirements. It can also be an alternative path to energy code compliance if the required HERS Rating cannot be obtained.

HVAC load, sizing and design is critical to building occupant comfort. Our team ensures your system is the best fit for your building. A smart investment now to install the correct system in the home will prevent comfort issues and complaints down the road. Customers usually select these services at the beginning of the project as it is most efficient for us to calculate during initial energy modeling.

Enroll your project in Mass Save for additional benefits and incentives. We manage the whole process for you. Mass Save offers various incentives. As of late 2018 builders can still obtain free LED light bulbs for buildings. Additionally, builders can qualify for subsidies if the building passes Mass Save requirements. As your HERS Rater, we also qualify for a subsidy which we pass on to you as savings on your final invoice.

Whether you're gut renovating a building in Boston or adding an addition to a property, we can help with any required inspections and tests that the building inspector requests. If you don't know what the building inspector wants, ask us! We know exactly what they're expecting.
