This exciting special edition of Green Building & Design (gb&d) is the official magazine of the 2014 North American Passive House Conference in San Francisco. Created in collaboration with PHIUS, it showcases the master builders driving the booming world of energy-efficient design in the Bay Area.

On the Cover: Passive House expert Prudence Ferreira helped San Francisco architect David Baker design the Zero Cottage, named for its status as a Net Zero Energy-certified project. Cantilevered over the courtyard is a solar array that provides 100 percent of the energy required by the home-workshop hybrid.

Also Inside: PHIUS executive director Katrin Klingenberg on new climate-specific energy standards; Seattle architect Brandon Nicholson on scaling up the passive approach; case studies on über-efficient windows, insulation, and sheathing; and much more!
