For as long as I can remember, the agreed epidemic with ductwork was always undersized return ducts. Although we are far from perfect with duct sizing in New England, I have frequently seen great strides in fixing this issue - particularly with replacement systems. Lets face it, you should just be properly designing the duct system on new installations. Undersized ducts cause great restrictions in airlfow, raising…Continue

Homeowners are often aware of the different problems they experience in their homes: uncomfortable rooms, high utility bills, poor indoor air quality, etc. However, homeowners are generally unfamiliar with the concept of Home Performance, the Whole House approach, and how energy efficiency upgrades can address these concerns. We regularly hear these stories and find that by listening, asking the right questions, educating, and providing guidance, we can help homeowners feel…Continue

On the flight home from ACI’s 2014 National Home Performance Conference, I read Charlie LeDuff’s Detroit: An American Autopsy. It’s a gritty, sad story about the decline of one the greatest U.S. industrial cities. It was fitting that ACI’s conference was held in Detroit–thanks to the growth of the auto and wartime industries in the early 20th century, Detroit was the birthplace of the U.S. middle class. But according to LeDuff, Detroit, which “once led the nation in home ownership,…Continue

Let me first start by confessing my guilt... Guilt for being bored easily, guilt for wanting praise, even if it is a pat on my own back for an achievement... Guilt for being a millennial... On the other hand I enjoy working in teams and I encourage frequent communication between all team members from admin staff to auditors, sales staff and crew members to improve our workflow. Yes, I am a millennial, but let me add that there is nothing that makes me cringe more than the excuses I get from…Continue

The Residential Energy Services Network (RESNET) announced its collaboration with the International Code Council last week in an effort to help home builders transition to the new 2015 International Energy Conservation Code (IECC). In the upcoming version of the residential building code, RESNET's HERS Index will be an optional compliance path — some people are saying that this compliance path represents the most significant change coming to 2015 IECC.
What is the…Continue

Cities grafting green-building certifications like LEED into commercial building codes is nothing new, and a number of places like Dallas, Atlanta, Boston and Scottsdale have had such requirements in place for a decade or more.
What’s happening now is that cities are doing likewise with…Continue

Doing testing of existing homes it is typical to see mottled patterns of surface temperatures with the FLIR Infrared Thermal Imager during Blower Door Testing.
Part of the problem is air sealing and the other part of the problem is poorly installed fiberglass insulation.
This is not a rant against fiberglass insulation (I am a fan of both Rock Wool/Roxul and dense packed cellulose) for retrofit projects. Fiberglass batt or blown insulation can perform fine, if it is…Continue

This list does not represent the entire code, or even all municipalities. Everyone knows those towns that will hit you on every piece of the local code requirements, word for word from the text. But, don't be surprised when code officials, both building and mechanical inspectors, start failing permit inspections for these previously rarely enforced portions of the code! Are you going to wait until enforcement, or lead the industry in doing what the minimum is required by…Continue
I'm pretty new to this whole industry... And by new I mean that the jumble of acronyms and terminology are still enough to leave me a bit dazed when some well meaning individual spurts off several in one sentence.
Home efficiency is not a field I ever could have imagined being involved in. By training, I'm an a ballerina. I've danced since I was three, trained in NYC, graduated from a conservatory... the works. And yet here…Continue
