A home energy audit is the first step on the path toward a more comfortable, more affordable, healthier home. Using a variety of high-tech, state-of-the-art tools, we're able to identify the key areas where your home is wasting energy, and recommend the most cost-effective improvements for maximum comfort, minimum energy bills, and optimal indoor air quality and building health and safety.

Our approach in conducting home energy audits is to take a comprehensive, whole-house assessment of the home, which distinguishes our "whole-house energy audit" from the "clipboard audits" offered by many utilities, box stores, and companies that offer a discounted audit as a means to sell products or services.

Our whole-house energy audit looks at the building envelope (which inludes all the components that make up your home's outer shell, including windows, doors, insulation levels, and the level of air leakage in between building materials); all combustion equipment including boilers, furnaces and water heaters; and the movement of air within the home to ensure that the air you and your family are breathing is fresh, healthy and safe. During the audit, we use an infrared camera to identify air leakage and deficient insulation, a blower door to measure the rate of air infiltration in the home, and a duct blaster test to determine whether your ducts are well-sealed, among other tools. 

Contact us with any questions or to find out more about our home energy audit process; we'd be happy to chat.

  •  I was just in the back room. In my stocking feet. Which did not immediately turn into little blocks of ice. Having lived in drafty old houses in NH all of my life, I am *astounded* at the difference good insulation makes. Seriously. I knew this was the right thing to do, but I had no idea

  • As a commercial builder  I have used many insulation companies for our commercial buildings, but building my own personal home, I needed to make sure everything was perfect.  Building Efficiencies insulated my 5000 sq ft Energy Star home and we achieved the highest results possible.  Thanks
