Zero Cottage: San Francisco's First Net Zero Passive House

0 notes &

There was so much salvage maple flooring from the Tassafaronga Village Pasta Factory that after using it for the two living level floors we still had a big pile.

About this time I became aware of the Japanese (and Finnish) practice of finishing exterior wood by charring. This produces a beautiful deep black finish that is quite durable and very wabi sabi.  The traditional reasons for charring are to provide a durable layer of carbon for weather protection and for fire resistance. In Japan they make a three sided chimney out of wide cedar boards and set that on a charcoal brazier. Flamed shoot out the top. We used a roofing torch to char the boards.

They are screwed to vertical cedar battens to form a low tech rainscreen.
