The American Institute of Architect’s massive Brutalist national headquarters in Washington, D.C., designed by The Architects Collaborative and completed in 1973, is a relic of another era. To mark Earth Day this year, the association has unveiled plans for a major, and majorly sustainable, building renovation. Architects EHDD, in collaboration with Hood Design Studio, Hartman-Cox Architects, Point Energy Innovations, and Turner Construction, are targeting LEED Platinum with new double-pane windows, roofing, and energy, lighting, and HVAC systems. The interiors are also being remodeled to emphasize a more inclusive and non-hierarchical work culture. “Given the current state of our headquarters, we can’t afford not to make this critical investment in the future of our organization and the profession,” said AIA executive vice-president and CEO Lakisha Ann Woods in a statement to the press.
