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

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

Every home is unique and differs from the last. It would be a perfect world (from a project planning standpoint) if every home were a cookie cutter from the previous install, however this is not always the case. I have been in the construction industry doing remodeling and even building new residential homes for over 25 years. Along the way I have run into some interesting situations in which I was not prepared and wished I was. Although this has been sometimes fun and challenging at times,…Continue
It is all ways great advice for small businesses to diversify, I know it pulled our company through a recession and is solely responsible for us coming up on our 20th year in business. With home improvement companies and electrical contractors, the advantages of being a Certified Infrared Thermographer go far beyond diversifying the small business…Continue

Lets face it – building science is pushing the performance of adhesive tapes to a new levels and though I can’t profess to have my daughters’ ability in making fashionable duct tape purses, I have been know to mis-apply good tape to get me out of a bind! I think Red Green would be impressed!
If you send me your photos, I…Continue
Thermostatic Expansion Valves (TEV or TXV), one of the most popular metering devices for residential, high-efficient air conditioning and heat pumps, have performed almost impeccably for decades. Unfortunately, some manufacturers in the past few years have identified batches of valves that have had high superheat issues. Have we just been blind for so long, not realizing these problems existed? Or have these valves really been so reliable for such a long time?
If you think you…Continue
I am a whole house fan and attic ventilation expert in Temecula CA. I started studying whole house fans in 2008 when my wife, Darlene, and I moved from Manhattan Beach. I would really like to share my knowledge with all of you but I want to be sure I don't antagonize you with more commercialization than you want. Please let me know your opinion and if you can, send me some examples of acceptable blogs and unacceptable ones.
