a D a m J o s E P h l E w i s C E n t E r f o r E n v i r o n m E n t a l s t u D i E s application of ecological design principles to projects ranging in focus and scope from green technology to local foods to urban revitalization. The Lewis Center is an integrated building-landscape system that provides offices and teaching spaces for Oberlin College’s Environmental Studies program. David Orr, the Paul Sears distinguished professor of environmental studies and politics, initiated the design process in 1992 by offering students the opportunity to consider how a new or renovated facility could best serve the growing needs of the program. Ensuing design charettes engaged green building and environmental technology professionals in a conversation that considered how “state-ofthe-shelf” technology might be combined with state-of-the-art design to generate a laboratory for the emerging field of ecological design at Oberlin and beyond. (See Table 1, Page 22, for initial project goals.) arrays, energy consumption by each of the major end-uses within the building, weather conditions, soil temperature and moisture, on-site rainwater storage, biological activity and water flows within the on-site wetland-wastewater treatment system (the “Living Machine®”) and a host of other variables. A Building Dashboard® in the lobby presents real-time data in a format designed to engage a nontechnical audience.

The ground source system circulates liquid into eight 250 ft deep wells and through a series of heat pumps within the building. Two large heat pumps temper fresh air on the east and west sides of the building and a pair of water-towater heat pumps provide radiant floor heating for the atrium space and baseboard heat for the Living Machine. Offices and classrooms are heated with a total of 16 individual heat pump units. Occupants control heating and cooling in the offices. Classrooms are heated, cooled, ventilated and lit by a building automation system that combines scheduled occupancy with motion sensors, CO2 sensors and light sensors. All offices and classrooms have operable windows. Winter 2011 HigH assessing Performance To capture high resolution data for research, ongoing commissioning and education, approximately 150 environmental sensors were installed throughout the building and landscape to monitor all aspects of building function. The sensors were installed between 2001 and 2004 in partnership with the National Renewable Energy Lab. These sensors continue to monitor energy production by solar Opposite The Lewis Center houses Oberlin College’s Environmental Studies program. Early program goals called for a building that would harvest and convert sunlight into indoor heat, food, light, biodiversity and electricity while emphasizing responsible use and cycling of materials. To accommodate growth of the Environmental Studies program and additional faculty members, an existing conference room was split Performing Buildings 21
