Because I've written so much about moisture in buildings, I get a lot of questions on the topic. Some are about walls. Some are about the attic. Some are about windows. Some are about the crawl space (which generates the…
When I woke up Saturday morning, the temperature outdoors was -40 degrees†. The wind chill was -100 degrees! It was just unbelievably, impossibly, inhumanly cold outside. Fortunately, that was on a mountaintop in New Hampshire and not where I was.…

Today we take the next step on our stroll through the laws of thermodynamics. As you know from reading the first part of this series, the numbering of the four laws begins with zero, so here, in the second part,…
