A fire nine years later destroyed the thin acrylic membrane that covered a building from this year, which is built with three-inch steel tubes that become thinner near its top. Elevators in a building opened in this year stop at every fourth floor to keep down energy costs, giving access to (*) pedestrian streets. 600 cubic, prefabricated concrete boxes were crane-lifted into pseudo-random stacks for a residential building from this year, as was a building made up of a steel and glass geodesic dome. For 10 points, name this year in which Moshe Safdie built Habitat and Buckminster Fuller built the Biosphere for a World's Exposition in Montreal.
