A Beautiful Solar Home in Utah Nears Net Zero Energy Use

Posted by Allison Bailes on Wed, Mar 18, 2015

I'm writing this on St. Patrick's Day so let me tell you a wee bit about the O'Mearas. Kevin and Svetlana O'Meara live in a beautiful home in Utah that's oh-so-close to being a net zero energy home. After I wrote about how home building is like skiing two years ago, Kevin invited me out to see their home and this year I managed to do so. My wife and I visited them for two days last week and Kevin told me all about the house, including his one major regret.

The Drainage Plane Flashing Battle Continues

Posted by Allison Bailes on Mon, Feb 2, 2015

I don't think I can ever say it enough, but the building enclosure consists of several control layers and each one has its job. The primary control layer is the one that keeps liquid water out, and it can be a tricky business. Take the case of this condo building (yes, it's in the community where I live). It's got several problems, so I went to bat for building science here.

2 Bad Ways to Install Windows the Hard Way

Posted by Allison Bailes on Fri, Nov 14, 2014

I see a lot of interesting stuff at construction sites and in people's homes. I also see stuff I never got to see because people send me photos. I like photos! Remember that ice chest someone had incorporated into a duct system? That was sent to me. So are the first two photos below.

Why Is Clark Howard Giving Bad Energy-Saving Advice?

Posted by Allison Bailes on Mon, Aug 18, 2014

Clark Howard is the penny pincher's guru. My wife loves his radio show and website for all the money-saving tips he provides. Naturally, anyone trying to help people save money at home has to address energy use, and Howard does, too. Unlike some others, though, he's generally well educated on the topic because he's hung around the Southface Energy Institute enough to know the basics. (I don't know if he ever used the clip, but he filmed me teaching how to do a blower door test there a few years ago.)

Stockton Project Demonstrates Huge Home Energy Savings

Posted by Allison Bailes on Tue, May 20, 2014

At the Forum on Dry Climate Home Performance earlier this year, I got to hear three building science experts talk about a really cool research project they've been working on in Stockton, California. Bruce Wilcox, John Proctor, and Rick Chitwood (Wilcox and Proctor shown in photo at left) filled us in on the Stockton project, which now has two years of data and shows some really impressive results.

Fixing an Old House? Follow Einstein's Advice

Posted by Allison Bailes on Mon, Nov 4, 2013

I get a lot of questions from people asking how they should go about fixing their homes. Sometimes it's specific (What's the best way to insulate my kneewalls?), and sometimes it's a hands up in the air, With all these problems, where do I start?  I'll focus on the latter today and let Albert Einstein provide the guidance you need.

Confessions of a Building Science Zealot

Posted by Allison Bailes on Mon, Sep 30, 2013

Hi. My name is Allison, and I'm a building science zealot. I preach the gospel of building science, yet in my own life, I fall short of the perfection I exhort others to attain. Yes, I once built a green home that had many of the features I promote here, but if you've been reading this blog for a while, you know that my current residence is far from perfect. How so? Let me count the ways.

Don't Try This Recycling Trick at Home!

Posted by Allison Bailes on Thu, Sep 5, 2013

I confess that, back in the '80s, I might have done the same thing this couple did. I remember reading Mother Earth News and Practical Homeowner magazine articles about folks who collected discarded materials to use in their existing homes or to build a new one. Take that man in Colorado, for example, who had a materials stash big enough to build a whole, nice-sized house for only $5000. That was cool! Since then, however, I've learned why I would have regretted building a house resembling what you see below.

Why Are Your New Homes Missing out on the $2000 Tax Credit?

Posted by Allison Bailes on Fri, Aug 30, 2013

Psssst. Want a $2000 tax credit for that energy efficient new home you're building? A lot of home builders have taken advantage of this incentive since it was introduced in 2005. (37,506 homes got that $2000 in 2010 alone.) The requirements haven't been so difficult for builders who do proper air sealing, use better-than-code windows, and install high-efficiency HVAC equipment. But then Congress made what seems like an insignificant change when they renewed the tax credit.

Passive House — The Only Place Where Real Innovation Is Happening?

Posted by Allison Bailes on Tue, Aug 13, 2013

Last week, Joe Lstiburek gave the fifth annual twitterview from his crawl space. (When he gets back from sailing this week, Peter Troast of Energy Circle has promised to publish the transcript.) One of the pearls of wisdom dispensed by Joe was that, "Passive House is the only place where real innovation is happening."
