Illumination

> Clerestory

I noticed right away in Oregon that even when it rained it was quite light out. But indoors, in homes with low ceilings and deep overhangs it was dark and gloomy. In Auerhaus four, 6-foot tall clerestory windows primarily meant for passive solar heating, have perhaps had the greatest impact on illuminating the interior. This greatly reduces electricity use, and gives the commodious living area an uplifting quality even in winter. More entrancing still is to see shafts of moonlight light up objects or to see stars twinkling through the windows.

>Sun Tunnels

Instead of windows on the north wall I chose to use four, 24" Sun Tunnels. As the picture shows, I liked the Sun Tunnels because they allow more flexibility in placement. The skylights could be aligned in a row on the roof while inside the locations vary considerably.

>Electric Light

To light up the main living area I used 3 industrial, 500-watt area lights meant for outdoor use. They were cheap ($10 each) and have a lot of negatives. They waste a lot in heat when used in the summer. They face south and reflect off the ceiling. Much light is wasted as it shines through the clerestory windows as light pollution. This produces a dramatic Batmanesque projection into a foggy sky. I've often thought I could pay for the house by etching the image of the Virgin Mary onto the window.
