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.
