Since 1990, when the American Institute of Architects’ (AIA) Committee on the Environment (COTE) hosted the first COTE Top Ten Awards, the announcement of each year’s winners has been eagerly anticipated. Each design is judged on 10 design principles established by COTE, including their respective social, environmental, and financial impacts. Considered the highest honor for buildings that display an outstanding committment to sustainability, the awards will be officially presented to the victors at this year’s AIA Conference in New York City.
