Construction on the Orchard House Residence Halls at Chatham University’s Eden Hall Campus (Mithun Partners) in Richland Township, Pennsylvania was completed in 2016. The new Net-Positive goal project is the first student housing project in the United States to use drywall as a radiant heating and cooling system; there are no radiators, heat pumps, fan coils, or equipment in the dorm rooms to ever remove or maintain. Targeting an EUI of less than 20 kBTU/sf/year, the project will be offsetting its energy use through high efficiency PV panels with integrated solar thermal heating for radiant space heating and domestic hot water.
Interface Engineering worked diligently with Mithun’s San Francisco and Seattle offices to create a high efficiency envelope including triple glazed low-e windows and highly insulating window framing systems. This will be the third Net-Positive project on the Campus. The first phase included a classroom, aqua-culture labs, and equipment rooms for the constructed wetlands. The second phase included the new dining hall and food service building and the new student housing. Read the case study here.
