At my first Building Science Summer Camp in 2011, David Hill (in the photo below) gave a great presentation on some of the big problems with duct systems. (In case you weren’t reading this blog back then, I got myself invited with my 2010 article called I Don't Need No Stinkin' Building Science Summer Camp.) Michael Chandler ably summarized that talk in his article, Stuff I Learned at Joe Lstiburek’s House, Part 2. This year, Hill did a followup presentation, reprising some of his main points but also adding two new pieces, one of which is a nice study he's been involved with on air flow in oval ducts.Read More

The Nest thermostat has been around since October 2011, quietly collecting data on how your home — and the homes of hundreds of thousands of your neighbors — operates. It gathers information about indoor temperature, relative humidity, air conditioner runtime, auxiliary heat operation for heat pumps, and much more. Unlike the Ecobee thermostat, however, Nest doesn't let its owners see all those data (which is a problem only for energy geeks really). Enter Michael Blasnik.
I love the ACI National Home Performance Conference! This year's conference was spectacular. It was in New Orleans, which is always fun. The stars of home performance were there. The Californians came back. (That's one of them in the chicken costume below. ACI after dark, which even has its own Twitter handle, @ACIafterdark, is fun no matter where the conference is, but wild things can happen in NOLA.) And perhaps best of all, Michael Blasnik revealed data from the Nest thermostat for the first time.
Last week I got a chance to sit down and talk with Terry Brennan in Dallas at the Air Barrier Association of America’s annual conference. He may not be as famous as Joe Lstiburek, but he’s every bit the building science pioneer. Armed with a physics degree, the ASHRAE Handbook of Fundamentals, and a desire to reduce the environmental impact of buildings, he built houses and wrote energy modeling computer programs back in the 1970s and ‘80s. When he finally met Lstiburek in the early ‘80s, he learned not to bet against Joe’s ability to do ridiculous things. Read the transcript of our conversation and find out what that bet was and more.
The ACI National Home Performance Conference is only a month away. Even more important, the deadline to get the Early Bird rate on the registration fee is Monday, 6 April. If you work on homes, this conference is for you. Here are 7 reasons why.
I love going to conferences. Since I changed my career in 2004, I've gone to building science, green building, and home performance conferences nearly every year. (I think I missed 2006, but I had a lot going on then.) Last year I went to eleven of them, but then I'm a bit unusual.1 You certainly don't have to go to that many, but if you're a home builder, home performance contractor, or home energy pro, I do recommend going to one a year so you can keep up with the latest trends, talk to your peers, and maybe add some arrows to your quiver.
The 9th annual North American Passive House Conference happened two weeks ago in the San Francisco Bay Area of California. The Passive House Institute US (PHIUS) has been holding this conference every year since 2006, and it just keeps getting better. I've been to the last three now, and it's one of my favorite events of the year, right up there with Building Science Summer Camp (Dr. Joe Lstiburek's conference) and Possum Drop (the New Year's Eve party I go to each year in Georgia). This year's conference seemed especially good because of the direction PHIUS is taking the passive house movement in North America.
The 9th annual North American Passive House Conference is less than a month away. You knew it's going to be in California, right? It's unfortunate that the other passive house group has chosen to use the same name PHIUS has been using since 2006, but I've already discussed that confusion. All you need to know is that the main passive house conference is in California, not in Maine. And here's why you ought to get yourself registered for it ASAP.
August for me is dominated by Building Science Summer Camp. It's a great event with lots of learning, great discussions, and meeting friends, old and new. I'll be writing about Dr. Chris Timusk's presentation on his OSB research later and possibly one or two other topics. Hal Levin spoke most of Tuesday, and, after his rambling, two-hour introduction, his talk on indoor air pollution was full of useful information. Today, though, let me just give you this nice little video that Matt Risinger put together from interviews he did with me, Joe Lstiburek, and Mark Laliberte.
Last week at the Affordable Comfort Conference (also known as ACI), I co-moderated a panel called The Great Ventilation Standard Debate.1 Duncan Prahl of Ibacos proposed the session and rounded up a collection of some of best building science folks in North America to be on the panel. And if you’ve been paying attention to this blog, you know who one of them was.
