each or graduate families. There are also three small residence halls that feature open doubles. More than 2,000 students live on the South Campus, which is one mile away from the Main Campus and connected by frequent shuttle bus service. Administrative, athletic, and recreational facilities South Campus is home to the Institute for Sensory Research, Tennity Ice Skating Pavilion, Comstock Art Facility, Skytop Softball Stadium, Skytop Track, Goldstein Student Center, Outdoor Education Center, Skytop Office Building, and the InnComplete Pub, a graduate student bar. Just north is the headquarters of SU Athletics, the John A. Lally Athletics Complex, formerly known as Manley Field House. Named after alumnus John Lally, the academic and athletics village is home to 20 Syracuse University athletics teams. The complex is surrounded by other athletic facilities, including the Carmelo K. Anthony Basketball Center, J.S. Coyne Stadium, Ensley Athletic Center, and SU Soccer Stadium. Downtown Syracuse In December 2004, the university announced that it had purchased or leased twelve buildings in downtown Syracuse. Five design programs—Communication, Advertising, Environmental and Interior Design, Industrial and Interactive Design, and Fashion—reside permanently in the newly renovated facilities, fittingly called The Warehouse, which was renovated by Gluckman Mayner Architects. Both programs were chosen to be located in the downtown area because of their history of working on projects directly with the community. The Warehouse also houses a contemporary art space that commissions, exhibits, and promotes the work of local and international artists in a variety of media. Hundreds of students and faculty have also been affected by the temporary move of the School of Architecture downtown for the $12 million renovation of its campus facility, Slocum Hall. Since 2009, the Syracuse Center of Excellence in Environmental and Energy Systems, led by Syracuse University in partnership with Clarkson University and the State University of New York College of Environmental Science and Forestry, creates innovations in environmental and energy technologies that improve human health and productivity, security, and sustainability in urban and built environments. The Paul Robeson Performing Arts Company and the Community Folk Art Center will also be located downtown. On March 31, 2006, the university and the city announced an initiative to connect the main campus of the university with the arts and culture areas of downtown Syracuse and The Warehouse. Using natural gas, the Green Data Center generates its electricity on-site, providing cooling for servers and for a neighboring building. The
