Duke has made significant commitments to sustainability through policies and initiatives to reduce carbon emissions and promote green building practices. Key efforts include converting the main campus steam plant from coal to natural gas, establishing sustainability committees, installing green roofs, implementing water conservation measures across campus, and obtaining LEED certification for new buildings including the Medical Science Research Building II (Silver rating), School of Nursing (Silver), and Duke Integrative Medicine (Certified).

Duke’s Sustainability Commitment Climate Action Plan – carbon reduction Retrofitting initiatives –roofs, water conservation LEED Building Policy – Silver or Better (2003) Hiring of Sustainability Staff Green Purchasing Policy (2004) Campus Environmental Policy (2005) Presidents Climate Commitment (2007) Committee on the Facilities and Environment Environmental Management Action Committee

3. Carbon Reduction 1. Conversion of the East Campus Steam Plant to burn natural gas over coal, increasing campus steam capacity by 35% Creation of a Campus Sustainability Committee to develop a Climate Action Plan with recommendations in 5 areas: Energy, Transportation, Offsets, Education, and Communications

4. Green Roofing Approximately 7,500 sf are currently vegetated, including the hospital clamshell. Recently refurbished for patient, visitor and staff use, the hospital courtyard functions as a “sustainability lab” with several sedum varieties, mosses and ferns planted in different light conditions. The courtyard also features zero to low irrigation landscaping, recycled materials, solar cells, roof water harvesting and a cistern.

5. Water Conservation In 2007, several efforts were launched to reduce water use in existing facilities: 1. automatic flush fixtures were switched to manual with dual-flush handles. 2. bulletins was posted throughout campus encouraging people to report leaks 3. cooling units were reconfigured to recycle water locally and at central chiller plant 4. campus cisterns and other non-potable water sources were used for irrigation 5. hand sanitizers were promoted to reduce the need for hand washing In the first six months, campus water use dropped 36%, saving 38 million gallons. At the Hospital, a 26% reduction was achieved, saving another 18 million gallons. In total, 70 million gallons were saved in the first year of implementation.

7. LEED Overview – MSRB II MSRB II Green Features 34 points, Silver Rating MSRB II is the fourth Duke building to earn silver; the others are SON, the French Science Center, and Fitzpatrick. Nationally, there are fewer then 400 Silver awards. Building orientation maximizes sun exposure for use of daylight Clearstory windows, aluminum sunscreens and sun-shading devices help cool spaces High efficiency fixtures and mechanical systems lower water and energy consumption Sloped ceilings and light shelves help bring natural light deeper into the building Light-colored finishes maximize light reflection to lower energy costs Use of recycled materials – including steel, gypsum board and concrete Use of local materials – stone, pre-cast materials and mechanical systems all from N.C. Heat-recovery wheel keeps air temperature at a more consistent temperature naturally Use of low-VOC (volatile organic compound) products – including carpets, tile, wood, paints and sealants “ Green Housekeeping” custodial service (Green Seal chemicals, microfiber mops, recycled paper products and HEPA filters)
