Preservation Green Lab

The Preservation Green Lab connects old buildings with new ideas. Guided by the belief that older buildings and blocks are essential to creating sustainable, equitable, and affordable cities, the Green Lab conducts research, delivers tools, promotes policies, and convenes partners to deliver a new kind of economic development leveraging existing buildings and underutilized spaces.
