The classic chart demonstrating the importance of keeping to the middle of the relative humidity spectrum has been shown to countless attendees of classes, conference presentations, and webinars on building science, indoor air quality, moisture problems, and health. I can't…
I used to be a smart-ass who would say things I thought were clever but really were just annoying. When I learned the basics of quantum physics, for example, I had a clever/annoying answer for anyone who asked me, What's…
Back in 2018 I wrote a series of articles on indoor air quality and filtration. One of those articles, The Unintended Consequences of High-MERV Filters, has seen a flurry of activity in the comments over the past three weeks. It all…

Well, there's nothing like a little pandemic to completely upend our daily lives as well as our short and long-term outlooks for the future. I've spent far too much time reading about, listening to, and watching news about the novel…
Energy efficiency is a gateway drug to building science. When you really start learning about it, you come to the inescapable conclusion that there's so much more to making homes better than just saving energy. A house is a system,…
Back in 2004, as I was immersing myself in the world of building science and green building, I took the US Green Building Council's exam to become a LEED Accredited Professional. I bought their book. I took a study course…
It's that time of year when heating systems start coming out of their summer hibernation. (Except maybe in Vermont. Michael Blasnik's Nest data showed that Vermonters are about the last to start heating their homes in Fall.) Then everyone starts…
Lying in bed. Feel like I've run a world record mile. Can't...catch...my...breath. I take the deepest breath I can. The noisy air provides little sustenance for my oxygen-starved lungs. Heeuunnnnnnnnhhhhhh... What brought it on this time? Was it a feather…
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: …
