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

Brainy light bulbs. Refrigerators that heat dishwasher water. Elevators that use no more energy than toasters. These are just a few of the “Oh Wow’ topics last week at the annual EE Global conference.
But it was growth in cities – and their buildings – that was clearly on the minds of industry leaders, 500 in total who gathered at the Washington, D.C. event, sponsored by the Alliance to Save Energy.
The US spends $432 billion per year on energy for buildings –…Continue

Ever wonder how appraisers develop value of houses with green or energy efficient features? Residential Green Valuation Tools was published last month by the Appraisal Institute. The 189-page book has 13 chapters that address the most often asked questions about the valuation process and green building. As the author of the book, I found the challenge of writing this book a great learning and…Continue
There are growing numbers of “green” builders and designers. Their focus is often on issues surrounding the health of the planet, sustainability, recycling, energy-saving, etc.
Some are also interested in the health of the occupants, but others don’t place as much emphasis on indoor air quality as they should, and many aren’t familiar with the needs of the growing population of chemically-sensitive people.
It is actually quite easy to claim that a building material is green.…Continue

When comparing renewable energy sources to fossil-fuel energy, there is little competition; renewable energy will win. In the quest for an alternative energy source, water, wind and solar power emerge as the top choices. However, the competition between the three is stiff. With this being the case, which one is the best?
With solar power, the sun’s energy is used to generate electricity or heat. Once captured,…Continue

Recently, Friedrich has modeled and sold in limited markets their DIY Mini-Split Heat Pump, Breeze. Just a few days ago, they scaled back their rollout in order to meet customer demand by limiting sales to New York and South Florida. I am torn between…

Van Jones delivered the opening plenary keynote speech for ACI's 2014 National Home Performance Conference in Detroit last week. I've been aware of Van's work since he started the Green Collar Job Corps program at the Ella Baker Center in Oakland, Calif., back in 2007. Van was the main advocate for the Green Jobs Act that was signed into law by Pres. George W. Bush in that year.
Under the Obama…Continue
Netflix, you were right. I liked Downton Abbey. And thanks, Amazon I do want to read Michael Lewis’ new book. I still can’t figure out how Google knows I have a new dog.
Even if at times it feels a bit eerie, such ‘consumer-of-one’ marketing is a convenience many of us have come to appreciate. And it’s an approach now embraced by most major retailers.
The exception? You’ve guessed it: the ever-old fashioned electric utility.
I did it. I survived my first conference in this industry, the 2014 ACI National Home Performance conference in Detroit.
When I joined The Energy Conservatory in June 2013 I was brand new to this industry. Before TEC I didn’t even know this industry existed, let alone what a blower door was. To help me learn all of this building science geekiness I decided to take BPI’s Building Science Principles course and exam. I read the book twice, and then took the exam, which I passed! I…

Detroit, ACI 2014
Chances are you were at the ASHRAE 62.2 debate, if you were at ACI last Thursday morning. While you were venting about exhaust or listening to Dr Joe drop F-bombs there was a quiet revolution taking place in room 330.
The WiFi revolution.
Retrotec and The Energy Conservatory - the two giants of pressure diagnostic tools- collaborated to show us the future. A future…Continue
