Environment, broadly defined, may be one of the most enduring subjects within modern architectural history and theory – from architectural historical writing on buildings and weather in the 19th century to contemporary architecture histories inspired by environmental humanities. This course examines many of the key themes and methods within architecture histories and theories of environment. These include histories and theories of climate, nature, ecology, regions, ecosystems, urban metabolisms, and material toxicities, among many other topics. We will focus on methods as much as the specific theoretical and practical applications of these ideas, with the goal of developing additional formulations out of them.
