We hired Building Energy to do an energy audit on our home. The resulting report was nothing short of a DISASTER. We had replaced our bath fans late 2020 with energy efficient well respected models. Both fans cost a total of 315.00. The energy audit suggested that we replace both fans with...THE SAME MODEL...and at a line cost of 1000.00 PER FAN. Our report was 'plumped up' 3k alone in fan costs. The report had pictures of locations of interest with no captioning to identify location and reason for interest. NOTHING indicates that these prices were assembled using any tool other than the audit

We had a terrible experience with this company and would never use them again.

We previously, about 8 years ago had a great experience with Building Energy on making our 1800 farmhouse much more energy efficient. They were expensive but did good work foaming our basement, which made a huge difference and insulting roof and attic spaces. We hired them to foam under our new small home which has a lot of windows and needed sealing up and the foam job was horrible. We had another contractor look at why we had a terrible time keeping the room warm after they foamed and put in a heat pump that is very costly to run and they said there were huge gaps that had no foam, and insuf

The Building Energy team far exceeded my expectations on the repair of our solar panels. They managed a difficult situation with great expertise and professionalism. I would highly recommend their services.

Building Energy did an amazing job with installing my solar panels, battery wall, and heat pump. Nick and his team are amazing and so responsive with my questions. I highly recommend them!

Despite being a busy season Building Energy was able to schedule a repair of our solar array less than two weeks after we contacted them. Our repair technician came on the scheduled day that the weather allowed. The array was up and running …

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.
What the company says about itself
Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.
Insured
“Building Energy is fully licensed, insured, and reliable! We offer honest…”
Licensed
“Vermonters. Building Energy is fully licensed, insured, and reliable! We offer…”
Its website also mentions free estimate and established, but not in a sentence we can quote cleanly.
Elsewhere
- Google also lists this company under insulation.
- It is also reviewed on Houzz. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
- It posts on YouTube, LinkedIn, Instagram, X and Facebook. A page that stopped posting years ago tells you something a listing will not.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.
What we don't know
- The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
- We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
- We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
