Ten years ago I was building a green home. It had passive solar features, was built out of structural insulated panels, sent all the greywater out to the back yard to water fruit trees, and was going to be super…
Yesterday I received an email and letter from Steve Ziessler, president and CEO of Guardian Building Products. In it, he apologized for their heavy-handed approach to expressing their displeasure with seeing their fiberglass batts pictured in an article on poor…
[UPDATE: 11/8/11 I received an apology today from the president and CEO of Guardian. More about that in the follow-up post.] See that photo? It's one of the reasons that I received a nasty letter from Guardian Building Products, a manufacturer…
This is the time of year when I start really appreciating hot water. We're getting a little bit of chilly weather, and those hot showers feel really nice in the morning. But that hot water† that reaches me in the…
I hear a lot of people call themselves building science geeks, energy nerds, home performance dorks, HVAC dweebs, weatherization wonks, and policy poindexters. (It's true! Some of them are imaginary people in my mind and some are aliens, but they…
Heating and cooling your home sucks more money out of your bank account than any other type of energy consumption (unless you live in a high performance home, in which case the proportions are different but the total is smaller).…
Ten years ago, I was at the front end of building a green, high performance home. (That's me on the ladder connecting the two LVL ridge beams that support the structural insulated panel roof.) It was going to take only…
I've spent a lot of time in attics looking at problems with insulation, air sealing, HVAC systems, and ductwork. I've also seen why so many bathroom ventilation fans don't move much air. A typical bath fan is rated to move…
Do you use hot water in your home? I thought so. You have a water heater then, right? You know, one of those things that you pump money into all the time, perhaps to the tune of $300 or $400…
I spent seven years in graduate school studying physics to get my PhD. You might think that the most valuable lesson I got from that experience would have been about the nature of physical reality. I was studying the positions…
