We believe that historic preservation and green building are closely linked, and that in many cases the greenest building is the one already built. We look for ways to reduce waste and create value through a combination of adaptive reuse of existing materials, and implementation of energy efficient technologies. In line with these goals, Hanson became certified for Passive House construction in 2013. We have relationships with many vendors of environmentally responsible building products, and are active members of the US Green Building Council, the Delaware Valley Building Council, and the Greater Philadelphia Preservation Alliance.
