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…
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…
Can an article on building science be out of date just because it's from 2010? Well, sure. If it's a news article about a program or code or standard that has since changed. But the principles of building science aren't…

Well, I really stirred things up with my last article on insulation and global warming. My intention was to explain why Alex Wilson's results could be doing a disservice to the green building community. In the end, I was rightly…
