Campus The University's campus is situated on 1,450 acres (Nipmuc land), mainly in the town of Amherst, but also partly in the neighboring town of Hadley. The campus extends about from the Campus Center in all directions and may be thought of as a series of concentric rings, with innermost ring harboring academic buildings and research labs, surrounded by a ring of the seven residential areas and two University owned apartment complexes. These include North Apartments, Sylvan, Northeast, Central, Orchard Hill, Southwest, Commonwealth Honors College Residential Complex, as well as the two University owned apartment complexes, North Village and Lincoln Apartments. These are in turn surrounded by a ring of athletic facilities, smaller administration buildings, and parking lots. The campus has its own Combined Heat and Power (CHP) generation facility. The plant, which was dedicated in 2009 after ten years of planning, replaced a coal burning power plant dating back to 1918 and has reduced the campus' greenhouse gas emissions by approximately 75%. In 2011, the CHP was recognized as the cleanest plant of its size in New England and has been recognized for maintaining 80% efficiency over six consecutive quarters. In 2008, the CHP received the Combined Cycle Journal Pacesetter Award for the best Combined Heat and Power plant project in the US that year. The award refers to its innovative design, efficiency, reliability, system redundancy, and environmental benefits. In 2009, the CHP received the Sustainable Campus Leadership Award from the International District Energy Association. The award states it was given "In recognition of exemplary public leadership in advancing energy efficiency and global environmental stewardship through investment in an innovative district energy system." The Environmental Protection Agency (EPA) presented the University of Massachusetts with the 2011 Combined Heat and Power Energy Star Award in an effort to recognize the reduced emissions and increased efficiency of the plant. The W.E.B. Du Bois Library is one of two library buildings on campus and the tallest academic research library in the world, standing at 26 stories above
