Energy Out West 2014

David Hepinstall (right) and his colleague from the Association for Energy Affordability in New York City through their work provide a powerful antidote to cynicism. I was at the Energy Out West Conference several years ago, but a memory still stands out from that event.

"It is curious to see a 15% difference in the duct test from the test out of 2007 to the current test in. If I had numbers like that I would question one of the tests or method of work performed in 2007. Assuming you had no work done to duct work or…"

John Proctor commented on Jim Gunshinan's blog post Energy Upgrade California—Up Close and Personal
"So Jim, any idea as to how your ducts sprung another 15% leakage between 2007 and 2014? You also know that models are just models, not real houses and may not really represent what you have or will get from a retrofit. Our round robin HERS…"

"As a few others have mentioned, it's interesting how much the test out from 2007 is different from the 2014 test in. Blower Door: 400 cfm50 on the blower door could be within variance on a leaky house, but that's substantial on a pretty…"

ARRA Keeps Working for You

Almost two years ago I posted a blog about the 2009 American Recovery and Reinvestment Act (ARRA); ARRA, or the “Stimulus Bill”, has gotten pilloried in the media as a colossal failure and waste of taxpayer dollars.

Because of ARRA’s support for DOE’s Weatherization…
