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…

In addition to saving energy, net-zero technologies offer a plethora of health, safety, and environmental benefits; but achieving zero energy can be prohibitively expensive. In this interview, Lucas Alm and Dan Handeen…Continue
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…

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.
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
It happened again yesterday: a new record (tell me if you know of a tighter house in Ontario if not Canada!) for air tightness was broken in Oakville by Certified Passive House Consultant (CPHC) Ed Marion of Passive House Ontario.
And this was just a pre-drywall test, so it can only get better from here.…
Sometimes we forget how complicated a house is. Building scientists know all about a house’s complexity because, even with help from supercomputers, they still can’t reliably simulate many of the processes taking place, let alone model the whole house. Perhaps the biggest challenge is that the darn thing can’t keep still. Cycles with different periods impose their wills on the structure and equipment in not entirely predictable ways. The seasons impose annual cycles for the sun and average…Continue

As usual, the ACI National Home Performance Conference contained too many highlights to mention in one blog post. So I will share just a few.
Got up early on Tuesday and went with Tom White, Home Energy Publisher, to a rehab house in a neighborhood of…Continue
The Appraisal Institute has developed a Residential Green and Energy Efficient Addendum. The Appraisal Institute Green Addendum is the first residential energy efficiency appraisal report addendum developed by appraisers, for use by appraisers when appropriate. This report evaluates items of high performance housing for consideration by appraisers.
Measuring the Value of Home Energy Efficiency
The Appraisal Institute Green Addendum will serve as a tool for…Continue

I'll be flying out to Detroit for the ACI National Home Performance Conference next Monday, but before get to Detroit and that great conference, I thought I'd share one more special moment from Energy Out West.
On Thursday afternoon last week, just after lunch, John Tooley, Anthony Cox,…Continue
Imagine if your furnace let you know when needed a tune-up, or if your home theatre saw you coming and turned itself on. According to Marc Jensen, managing partner and chief technology officer at space150, the Internet of…

I am in San Diego for the Energy Out West conference (see photo), and I want to write about it, but while it is fresh in my mind I want to fill you in on my latest Energy Upgrade California experience first.

When setting out to build an efficient house, the elephant in the room is air tightness. Industry is resisting mandated air tightness testing if thresholds are introduced meanwhile building codes are ratcheting up efficiency on all fronts except air tightness. Having debunked the myth that “a house needs to breath” its becoming painfully obvious to any building scientist that the lowest hanging fruit on the efficiency tree isn’t geothermal but simply producing a more air tight…Continue

Our furnace is approaching 25 years old and we have no cooling capabilities, so my wife Michele and I are looking into buying some new equipment before the temperature climbs this summer. I am especially interested in installing a mini-split heat pump, which would allow us to get rid of the ductwork and…
80 percent of Minneapolis’s housing stock was built before World War II, but 40 percent of these homes have never upgraded their wall insulation. After investigating barriers to completing efficiency projects, CEE’s latest report, Energy Fit Homes, proposes awarding a certificate to homes that achieve basic efficiency standards.
