It has come to my attention that there may be a building science-based conflict in the language of the 2012 International Residential Code (IRC) and 2012 International Energy Conservation Code (IECC).
The 2012 IECC sets the mandatory blower door tested and certified air infiltration rate at 5 ACH50 in CZ1 & 2 and an even tighter 3 ACH50 in CZ 3 and above. The problem lies in the fact that the new…Continue
New Study: "Impact of LEED-Certified Affordable Housing on Asthma in the South Bronx"
Here is more evidence that the occupants of energy efficient, healthy, and affordable housing enjoy better health compared to those in traditional low-income housing. The results of an in-depth study by Mount Sinai Hospital in New York City of residents who recently moved into LEED-certified low-income multifamily housing showed:

It says something that Ernest Moniz chose to deliver his first public talk as US energy secretary to an energy efficiency crowd.
His appearance last week at EE Global in Washington, D.C. was a surprise of sorts. And the timing was significant. Moniz had only been confirmed as energy secretary three hours before taking the podium at the Alliance to Save Energy’s annual conference.
Why did he make the stop?
Probably not because of the size of the crowd. About 550 people…Continue
Changing one’s daily routine and making big decisions about money is hard. When a home performance contractor asks a customer to consider an audit, they are asking a lot. Besides the cost of the audit and any retrofit measures the homeowner chooses to pay for, which is probably the biggest challenge, there is also the inconvenience. The audit and retrofit may require the homeowner to take time off from work. Having workers climb in and out of the attic, under the crawlspace, and drill holes…Continue

The easiest way to show a homeowner how their investment in high-efficient equipment will help their wallet is to use the "Simple Payback" Calculation. This 'tried and true' sales tactic will quickly explain how many years before the additional investment to upgrade is paid off. Of course, there are many features that a high-efficient system provides, like superior levels of comfort, wether it be climate control or just condenser noise just outside their children's bedroom. These…Continue

Based on the life expectancy of the heat pump that came with my house when I bought it, I know that I am already living on borrowed time. I just recently had a minor repair and the semi-annual check-up. My plans are to start preparing to replace it by next spring.
We don't see a lot of bi-partisan bills in Congress these days. Here's one focusing on home energy-efficiency from a WV-R and a VT-D, both on the energy committee, the HOMES Act, HR 2128 (http://hdl.loc.gov/loc.uscongress/legislation.113hr2128) introduced yesterday. Now, I'm not holding my breathe on passage, but I take it as a good sign that energy-efficiency is part of the…Continue
The late poet and political activist Muriel Rukeyser famously said, The Universe is made of stories, not of atoms. It’s not just words that make up stories. A scientific equation is a story, and so is getting up from my seat and stretching—it’s the story of back care for an editor. We can tell a story with the expression on our faces. What does it tell you when a loved one rolls her eyes at you, or blows you a kiss? How do you feel when a stranger winks at you? Flips you the bird? That last…Continue

His economic truth about homeownership:
By contrast, real home prices should decline with time, except to the extent that households shell out some money and plow back some of their incomes into maintenance and improvements, because homes wear out and go out of style.
"Here is a harsh truth about homeownership: Over the long haul, it’s hard for homes to compete with the stock market in real…Continue

We use drainage gaps or planes in wall systems to stop water from entering the building shell and causing deterioration or mould. This air gap does two things if wide enough; it prevents water’s surface tension from staying or even climbing up the wall and the gap also disperses the forces of wind driven rain or solar vapour drive. Let’s look at…Continue

Dave Robinson, a principal of GreenEarthEquities, is a man in this industry that needs little introduction. If you didn’t see him at last year’s ACI event accepting the Tony Woods Award, you may have seen him teaching a class, serving as the former president of the California Building Performance Association, or performing deep energy retrofits on…Continue
Solar Energy + Energy Efficiency Services – to DO or NOT to DO – is no more a Shakespearean dilemma!
The SMB solar installer finds himself in a challenging spot today
Much has been written in recent times on consumer attitudes towards investing in energy efficiency retrofits, a recent GTM article http://www.greentechmedia.com/articles/read/Can-Home-Energy-Efficiency-Gain-Traction?utm_source=SmartGrid&utm_medium=Headline&utm_campaign=GTMDaily does hit the nail on the…Continue

On two separate Quality Assurance site visits in the past two weeks I've detected elevated levels of Carbon Monoxide (CO) coming from attached garages. I was a bit surprised at this since neither garage contained a car - let alone any active source of combustion. So I did some digging and came up with this great resource from Iowa State on the topic. From my reading of…Continue
