One of the key components of an effective home energy audit is infrared thermography. Infrared thermography (or infrared imaging, infrared diagnostics, a rose by any other name...) consists of a thorough visual inspection of a home, including the basement, attic, and all the nooks and crannies, with an infrared camera or another infrared assessment device. It essentially takes the guess-work out... Read more

Sometime during your crusade to seal those energy robbing cracks and holes in your home, you're bound to start asking yourself, "Isn't air flow important for a healthy home?

Home Performance is a philosophy and a science based on the premise that homes should be safe, healthy, comfortable, durable, and efficient. After all, homes — probably the biggest investment most of us will ever make — are one of the few things we purchase that don't come with an instruction manual. Is a home comfortable? Reasonably energy efficient? Safe and healthy? These are all... Read more

Your utility bill may be shocking, but it offers few helpful details: it doesn't tell you when your energy use peaks, doesn't explain how best to reduce power consumption, and doesn't tell you how your home is spending your money. We think it’s worth finding out. A home energy audit is one of the first steps to understanding your home's energy usage, as well its overall health and performance.... Read more

There's understandably a lot of excitement about photovoltaics, solar water heaters, geothermal heat pumps and other sources of renewable energy for the home. We all want to be self-sufficient. It's part of our national psyche. And, particularly for the environmentally motivated among us, the desire to reduce our dependence on traditional energy sources is strong. But when looking at potential... Read more

Pending in the Senate is a bill called the Home Star Retrofit Act of 2010, or simply Home Star for short. Sometimes referred to as Cash for Caulkers in street slang, the bill would provide a series of financial incentives for homeowners to increase the energy efficiency of their homes through substantive, effective improvements to their homes that save homeowners money, reduce our country’s...

  • I would like to express how grateful to each and everyone of you for helping make my house warmer for the winter months, its because of you I was able to have insulation and seal areas of my home that wouldn't get done. Thank you!
    Wendy, Wareham, MA
  • Initially hiring Efficient Buildings for some insulation work, we were so impressed by their efficiency, expertise and depth of knowledge that we went on to hire him for a large addition.

  • I hired Efficient Buildings to do some insulation work at my house, as I had heard that attic insulation was one of the best ways to cut heating costs, and Efficient Buildings came highly recommended from a friend.

    James Chase, Bridgewater, MA
  • I wanted to tell you how great a job the installers did putting in my attic insulation. My AC has been out for a few days and the insulation has kept the temperature down. Usually a second story would be boiling, but the men did such a great job that I was able to stay here. 
    Diane, Osterville, MA
