Green Roofs: Ecological Design And Construction 
"Imagine the effect of community kitchen gardens on the rooftops of New York City," writes visionary green architect William McDonough in his forward. "The gardens would make visible the vital connections between water, soil, food, and human culture, and create a network of living landscapes across the ancient archipelago that is New York City."
Hundreds of photographs, forty case studies of exemplary green roof projects - from Mexico City to Malmo, Sweden to Fukuoka, Japan to Dearborn, Michigan - provide inspiration and guidance for green roof development, as well as design details. The book includes seven essays on green roof development in Berlin, Tokyo, London, Portland, Chicago, Toronto, and New York City. Additional essays detail the technical requirements, architectural history, and design possibilities of vegetated rooftops.
