A HERS® Rating is the most common method to show compliance with local energy codes and apply for utility incentives.

Building codes require a blower door test on all residential new construction and many renovation projects in Massachusetts.

We provide duct testing services to help HVAC contractors and builders comply with the new energy codes.

We can determine which code is applicable to your project and find a path to compliance that fits your goals.

We offer air sealing solutions to help you meet your desired building envelope tightness.

Utilizing REScheck and COMcheck software, we can quickly determine if your building project meets code compliance.

Does your project need Passive House certification? We can help! Our team holds both the Passive House Rater and Passive House Verifier certifications.

Are you looking to get your project LEED certified? Our Green Raters are involved from initial design phase and throughout the construction process.
