Energy Audits & HERS Ratings in Boston, MA
Find out where your Boston home loses energy with blower door tests, thermal imaging and a written report from certified raters.
Why BCI Group
Know exactly where your Boston home loses energy
Guessing where a home loses energy wastes money. A blower door test measures how leaky the building is, and thermal imaging shows where the leaks are, so every dollar you spend on upgrades in Boston goes where it counts.
For multifamily buildings, we test and rate units and help owners see where heat is lost between them.
From our base in Westborough, Boston is about 30 miles away, close enough for quick estimates and follow-up visits.
- Plain-language written reports
- Energy code compliance for builders
- Thermal imaging to find hidden leaks
- Testing before and after upgrades

What Boston homes need
Boston's housing runs from 19th-century brick row houses and brownstones in the South End and Back Bay to triple-deckers in Dorchester and Roxbury and single-family colonials in West Roxbury and Hyde Park. Many buildings are masonry or balloon-framed, with empty wall cavities and drafty top floors.
From Charlestown and the North End to Jamaica Plain, Roslindale and Dorchester, many Boston homes share walls with their neighbors, so most heat escapes through roofs, top-floor ceilings and basements rather than side walls. Harbor wind makes air leaks around old window frames and roof edges more noticeable in exposed neighborhoods like East Boston and South Boston.
Suffolk County is the most densely built county in Massachusetts, and its attached and closely spaced buildings lose most of their heat through roofs, top floors and basements.
