The Edward B Bunn Intercultural Center at Georgetown University in Washington DC exhibits an effective strategy for active sustainable design. The entire slopped surface seen here is oriented to the south and covered with photovoltaic panels. The building was built in 1982, however, so one wonders at the efficiency of the somewhat dated panels and even whether they are still functioning.
A quotation from French priest and paleontologist, Pierre Teilhard de Chardin, S.J., appears above the stairs leading down to its auditorium: “The Age of Nations is past. It remains for us now, if we do not wish to perish, to set aside the ancient prejudices and build the earth.”
