World Architecture News (WAN) recently named the Bullit Center in Seattle, Washington, as the WAN Sustainable Building of the Year. The structure beat out five global finalists, and was cited by judges for meeting all net annual energy needs with onsite renewable energy sources. According to WAN, the building's overhanging photovoltaic rooftop and facade provide the energy for the entire building by supplying 230,000 kilowatt hours per year. The overall energy usage is roughly 20% of the other buildings of its type in Seattle.
