Sustainability in architecture can take a bewildering number of forms, but ARCHITECT contributing editor Mimi Zeiger sets out to show that the personal is sustainable with Micro Green: Tiny Houses in Nature ($29.95, Rizzoli, March 2011). Described by Details as an “an anti-McMansion manifesto,” Zeiger’s book stresses innovation in sustainability at the individual scale. A follow-up to her 2009 book, Tiny Houses ($29.95, Rizzoli)—in which she surveyed home designs of 1,000 square feet or smaller—Micro Green reveals how compact living works in a variety of environments as well as how new innovations scale down.
