A brief description of when and why the energy consumption baseline was adopted:
We used 2007 as the baseline because that was the year the state of South Carolina adopted a requirement that all major state-funded construction and renovation projects need to meet Leadership in Energy and Environmental Design (LEED) design and construction criteria.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
Site energy | Source energy | |
Performance year | 0.06 MMBtu per square foot | 0.16 MMBtu per square foot |
Baseline year | 0.09 MMBtu per square foot | 0.27 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Over the past 15 years, all major new construction and renovation projects have been completed in accordance with green building standards. Seven of buildings are Gold-certified and five Silver-certified, which is the equivalent of approximately 835,000 square feet. CCU is also a member institution of U.S. Green Building Council (USGBC), which develops and administers the LEED Green Building Rating System (www.usgbc.org), and has two LEED accredited professionals on staff to ensure LEED criteria is incorporated in design and construction on all major projects.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
CCU’s campus has a 7,200-square-foot Central Energy Plant, which has the ability to pump up to 2,800 tons of cooling capacity. The Central Energy Plant currently services a number of buildings on main campus, such as the Smith Science Building, Swain Hall, Wheelwright Auditorium, Kearns Hall, and Lib Jackson Student Center. The goal of this Central Energy Plant is to get as many buildings off their own chillers and served by a central unit to reduce overall energy usage.
The plant itself is made up of a cooling tower, water-cooled chillers, and cooling pumps. All of the buildings supported by the plant receive their air conditioning via an underground chilled water distribution system. The system is controlled in each building with automated controls. The new system also uses existing natural gas systems to heat all of the buildings on its matrix. The advantage of the Central Energy Plant is that it allows for a more efficient system, housed in a smaller area - the plant takes up considerably less space than the combined number of units it will replace at the individual buildings. A similar central cooling plant is located behind the HTC Center, adjacent to student housing on Elvington Loop. This plant provides cooling capacity for those facilities.
