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 looking for their lotion and lip balm. Gaps appear in...

Supply and demand are two different things. When you think of an energy code, say the International Energy Conservation Code (IECC), you probably think of demand, not supply. Conserving energy, after all, means reducing demand. It's related to supply only indirectly. As a result, you might expect...

You can go into just about any introductory physics classroom and you'll see that the students learn the same stuff no matter which school they attend. They study forces and motion, momentum and energy, electrostatics, and a host of other physics topics. They do lab experiments. They observe and...

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.

Three weeks ago, I wrote about an attic with spray foam insulation and the interesting humidity pattern we observed in it. We placed data loggers near the ridge and floor of the attic as well as in the living space and outdoors. In that last article, I showed the dew point data for the four...

Like many energy geeks, I track my electricity usage and costs. I've been doing it for decades. (Unlike Danny Orlando, however, I haven't stayed in the same house and watched as the home energy improvements kept lowering that usage.) One thing I've noticed in the past few months is that the...

Spray foam insulation can solve problems that other insulation materials can't. One of those problems is moving the building enclosure from the drywall ceiling of a home to the roofline. By doing so, you bring the attic inside the building enclosure. But what happens to that attic space when you...
