I spoke to a window vendor today who has a lot of experience with Passive House projects. He pointed out that some of our windows are not sized very efficiently. The problem isn't the big windows -- it's actually the small ones that have a high frame-to-glass ratio (the glass has a better U-value than the frame).
With that in mind, I played with resizing the front clerestory windows, making them larger. I removed one of the front windows to keep the glazing numbers from getting too high, and I spaced them 14" apart so they won't look like they're squished in the corner. That will also make them much easier to install.
But Ted is not fully convinced, so we need to run it by Camilo (our architect). Instead of sending the pix in an e-mail I figured I'd just post them here.
Occupant behavior can make the difference between an efficient house and a wasteful one. Notorious energy hogs include plasma TVs, old refrigerators or freezers, ice-makers, and dehumidifiers. And don't overlook sneaky items like DVRs, always-on computer and entertainment equipment, etc.
