I did a little video of the windows in action over the coarse of a day. It was pretty impressive to see just how well they work. They video gives a better explanation of how the windows work as a system to not only capture and store the suns energy, but also how to control it as well.
I can't wait to see how well they work once the doors are installed.
Some other things that have been going on on the site is the interior framing, that was completed earlier this week. Along with installing the vapor barrier and insulation under the basement floor. Yes we not only insulate the exterior of the foundation but we also insulated under the basement floor and up along the sides of the concrete, eliminating a thermal break in the envelope of the building. Combining a highly insulated thermal envelope with air tight construction is what make a passive solar how possible. The higher the insulation level the lower the energy costs needed to control your indoor environment.
This coming week we will be installing the solar chimney. What is a solar chimney? Stay tuned and find out.
