The U.S. Green Building Council offers a certification program that grades buildings based on their adherence to sustainable practices Called the Leadership in Energy and Environmental Design certification (LEED), many college campuses use this to ensure that new construction projects are sustainable.
Based on metrics decided by the U.S. Green Building Council, buildings are assigned a rating based on how many points it accumulates: Platinum (80+), Gold (60-79 points), Silver (50-59), and Certified (40-49). The points span across many aspects of sustainability: Location and Transportation: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, Integrative Process, Innovation, and Regional Priority.

Case Study: McCourtney Hall
The daily operation of McCourtney Hall conserves energy and water. Throughout the interior and exterior of the building, LED lighting decreases the amount of electricity used, while occupancy sensors in the interior spaces reduce lighting power density, conserve the amount of airflow and reduce reheat energy. Notably, a heat recovery system moves heat from the exhaust air to the supply air during the winter months, and from the supply air to the exhaust air in the summer months, which reduces the consumption of chilled water and steam. Similarly, a heat recovery chiller moves heat from the chilled water return to the heating water supply, which also reduces the consumption of chilled water and steam. With high-efficiency fixtures and sensor metered lavatory faucets, the facility uses 37 percent less water than the standard new facility.
