It seems that we hear about new technology every day. New energy efficiency products. Many times I have been lead down the path, as I am sure all of you have, that leads to a disappointment.
I am writing this blog - my first one on Home Energy Pros - to inform all of you who really care, that I have been blessed to be able to work alongside someone who has invented a micro-CHP (Combined Heat and Power) that is ground breaking. In short, it's a furnace that produces…Continue

Liz Vogel replaced the windows and updated the heating system in her small multifamily building in the Logan Square neighborhood of Chicago. But she still noticed that parts of her home were not staying warm in winter. So she set out to solve the mystery of the missing heat. She saw icicles hanging from her roof, and that was a clue that pointed to where heat was escaping. The presence of these “ice dams” meant that Liz was paying to heat her roof and melt the snow instead of heating her…Continue

We're testing a newly-produced informational video, which our Michigan home inspectors share with their recent home-buying clients, to see how effective it is in driving demand for energy upgrades. Watch it at http://www.nachi.org/michigan-home-inspection-follow-up-survey.htm and share your thoughts.
Note to Homeowners: This article is primarily aimed at the Home Performance industry. I strive for radical transparency, so I put this in the public sphere for you to read as well.
Energy efficiency rebate programs from gas and electric utilities have become pretty common nationwide. They give rebates for replacing your furnace or adding insulation to your home. While these programs seem like a good idea, they can actually…Continue

The feature article introduces the young people who the industry can count on to lead the home performance industry for the next 30 years.
Home Energy’s associate editor, Macie Melendez, compiled the nominations and…Continue
When is it ok to put your ducts into an attic, tight up against the Roof Deck? With more conventional building techniques, I would have to argue: NEVER! I do not care how the homeonwer pleads to keep their storage space, you cannot count on delivering cool air to the conditioned space with said branch duct. Even if you did figure out a way to secure the duct to the peak without crushing the inside diameter, the CFM is not the problem. The real issue becomes the dry bulb temperature of…Continue

As I had brought up years ago, ACCA's Manual S was in dire need of an update. Written in 1995, Manual S Residential Equipment Selection was passed by with huge technical and efficiency strides within the…Continue
After the first week, the ductless heat pump and I became so close that could never even think of her as ugly. But some folks don't like the look.
In an analogy to current medical practice, the mini-split heat pump is fabulous but the side effects are minimal for some people. In those cases, we have a cure for the side effect, the LED sandwich light that mesmerizes the eyes softly and makes heat ugly pumps disappear right before your very eyes.…Continue

If you have not been asked to complete a duct test by your local Massachusetts Inspector, it is just a matter of time before you are surprised by this stringent/updated code requirement. Despite some push-back from Contractors and Inspectors, all of MA is required to test new or altered duct systems. All of MA adopted the 2012 International Energy…Continue

RaterFest! has many traditions... Bon-fires, Rater Jams, Rater Olympics, Colorado Craft Beers...
Perhaps one of the less well known, but dearly loved, is the tradition of Raters sharing stories about their own homes.
This year we are excited to have Jeremy Draper, who will tell his unique story of building his first home using as much recycled or re-used materials as possible. He is nothing short of a Craiglist master.…Continue

Hi there, I'm new here. Not sure if this make sense here. But for sure, you will tell if it's not.
I'm Portuguese, I've 47 years old, 3 children, and spent the last 3,5 years of my life on a project I've called Casa Automatica.
The project started by being just an home control system, where I've tried to combined some security features, water control and home network, in a package, using and sharing an internet connection. The system is presented here…Continue
You took a class, or read a book, got BPI or HERS Rater certified, or just bought some diagnostic equipment. Your company was heading in the right direction in the beginning, but NOW WHAT? Earning certifications and owning diagnostic tools is a step in the right direction, but it’s only a step… the real power of your home performance focus is in practicing what you preach with testing on every job, and using it to…Continue

There are two very active posts on zoned system bypasses. http://www.energyvanguard.com/blog-building-science-HERS-BPI/bid/44187/Navigating-the-Twilight-Zone-The-Hidden-Flaw-in-a-Zoned-Duct-System
On August 4th, the Building Performance Institute (BPI) announced a new certification focused specifically on blower door and duct blaster concepts. The announcement came during a monthly meeting for approved BPI Test Centers. The official announcement is slated to come soon. BPI Infiltration and Duct Leakage, or BPI IDL for short, will be a standalone certification that emphasizes proper handling of energy auditing equipment - and you heard it here…Continue
