Architectural lighting is a great way to bring a bit of life to unused buildings. A new program in Detroit aims to cast some of the city’s many empty structures in a better light, in an effort to “mothball” them for future use. The architects at McIntosh Poris Associates have an innovative plan to re-light the four buildings without generating carbon emissions, a plan they hope to expand across downtown. Commissioned by the Detroit Downtown Development Authority, the project will light the interior and exteriors with power generated from rooftop photovoltaics. In addition to improving the appearance of the buildings, the green lighting scheme will also improve pedestrian safety. It’s a small, smart step for Detroit. The city is down, but soon it’s lights won’t be out.
