This was an extensive remodel of an existing house, with a new penthouse and roof deck. The stairs were opened up and relocated to the center of the house, creating a solar chimney that allows for natural ventilation throughout. A framework mounted atop the penthouse supports an array of photo-voltaic modules, combined with solar hot water collectors.
Other ecologically sustainable elements in this project include: wastewater heat-recovery, rainwater harvesting, hydronic radiant floor heat, super-insulated envelope, rain-screen siding.
This house appeared in the June 2004 issue of DWELL magazine. It won a 2005 Built Green Design Award, and has been featured in numerous books and publications.
