The Robert A. Macosky Center is a former farmhouse that is home to a program called Sustainable Systems Education and Research.  DRS was commissioned to design a major retrofit for this building.  The first priority was a thorough envelope upgrade to increase R values in walls, floors and roof and reduce air infiltration.  Inefficient electric base board heat was replaced with a Geothermal heat pump system.  A new porch and entry was also added.  A new lighting system with vacancy sensors was added.  All materials were selected for durability, recycled content or other sustainable features.
