Drywall installers, plumbers, HVAC technicians. All those folks and more do a lot of the dirty work in the construction, maintenance, and renovation of buildings. It's often not fun. I've done it myself, so I know. As a teenager, I worked summers with my grandfather, an electrician, HVAC contractor...

Posted by Allison Bailes on May 25, 2016
The word "interstitial" comes up occasionally in building science discussions. I think I've heard it a couple of times at conferences just in the past month. That may be because Joe Lstiburek was there. He's the guy who used that word 127 times in his doctoral dissertation, Toward an Understanding...

Posted by Allison Bailes on May 23, 2016
When I began remodeling my master bathroom last month, I found the exterior wall ripe for some serious improvement. It had a number of problems, and I was excited to find them. It was worse than I imagined in some ways. The photo below shows the wall partially opened up.

The Building Performance Institute (BPI) recently introduced a new certification called the Healthy Home Evaluator. It's not a standalone credential, though. Anyone looking to add it to their list of credentials must already have one of three other BPI certifications:  Building Analyst, Energy...

Posted by Allison Bailes on May 17, 2016
If your home is old enough for a bathroom renovation, you may want to go ahead and completely gut it. I started my bathroom remodel last month with a complete demolition. If I hadn't, a number of problems would have been unavailable for repair...or even undiscovered. Here's what I found when I...

Matt Risinger is a home builder in Austin. He builds great houses and is also famous for his videos. He has over 26 thousand subscribers on his Youtube channel. I was in Austin last week for the inaugural Humid Climate Conference and had some extra time on Saturday morning. So I got a tour of a few...

Posted by Allison Bailes on May 6, 2016
It’s hard enough to control humidity in humid climate homes when they’re just built to code these days. The air conditioner traditionally has handled the dehumidification, but increasing requirements for insulation and air tightness affect the sensible load more than the latent. Then, when you go...

Posted by Allison Bailes on May 5, 2016
Can an article be out of date just because it's from 1989? That's not only three decades old, but it's also from the last century. Heck, it's even from the last millennium! What about more recent stuff? Is it better because it's newer? Well, maybe. But someone recently questioned the suitability of...

The Green Builder Coalition has been working hard on their Water Efficiency Rating Score — the WERS — for homes. The inaugural WERS training happened in Santa Fe, New Mexico in March. I was in that class, and I learned a lot. Now the program, which has been in development for the past couple of...

Professor John Straube is one of the smartest guys in building science. On top of that, I think he's the best presenter in the field. At the Air Barrier Association conference in Baltimore, he gave one of the best building science talks I've heard. Of the things he said, this statement really stood...
