My friend Perry had lived in a nearly hundred year old house for six or seven years when we encapsulated his crawl space in 2005. It was a typical old country house.

Mike Collignon from the Green Builder Coalition has been doing an amazing job getting this new program off the ground. Last year I wrote...

Every year on New Year's Eve, I head over to some friends' house here in the Atlanta area. They have the best party around—Possum Drop—and I've been going for nearly a decade now. As midnight approaches, the newly-crowned Possum Queen leads the countdown. The possum is lowered slowly onto the fire...

Posted by Allison Bailes on February 5, 2016
New Orleans is the home of jazz, Mardi Gras, and rot. I grew up about 70 miles southwest of NOLA so I know a little something about the rain and the swamps and the muggy air. It makes it tough on buildings because the moisture comes from so many directions, but it is possible to control moisture...

Posted by Allison Bailes on February 1, 2016
I know it's not air conditioning season, but this story is too good to wait until summer rolls around. My friends at E3 Innovate in Nashville — you may remember them for finding the home ventilated with dead possum odors — have done it again. This time they've discovered a crawl space with an...

Posted by Allison Bailes on January 29, 2016
Revolving doors have been around for a century and a half. You see them at the bottom of tall buildings, which tells you something right there. They weren't invented merely to function as a way to enter and exit these buildings. There's a building science reason behind their invention. In fact, the...

Posted by Allison Bailes on January 27, 2016
It was the best of times, it was the worst of times, it was the season of cold, it was the season of heat, it was the ignorance of what was right in front of us, it was the opening of our eyes, we had warmth in our homes, we had warmth in our attics — in short, the period was so like the present...
