The Fitzpatrick Center for Interdisciplinary Engineering, Medicine and Applied Sciences (CIEMAS) opened in 2004 and earned LEED™ Silver certification.
Sustainable Site Features:
CIEMAS includes features to reduce light pollution and substantially reduce heat island effects. A reflective membrane roof reflects 75% of incoming solar energy, reducing the need for air conditioning. High-albedo (reflective) pavement shaded by trees selected for the site also reduce absorption of solar energy, creating a cooler, more comfortable environment.
Xeriscaping, the practice of using local, native plants that do not require additional watering and fertilizing to survive, has eliminated the need for an irrigation system at CIEMAS. A 70,000 gallon rainwater cistern catches rain water, mitigating run-off and providing water for landscaping elsewhere on campus. Low-flow lavatories and waterless urinals reduce building occupants' use of potable water by 53%.
The stonework on the building's exterior slows the transmission of solar heat by about 12 hours, meaning the stones stay cool during hot days and begin releasing heat at night, when temperatures have cooled. Coupled with tinted windows that maximize daylighting without additional heating, these simple, cost-effective smart design features minimize the energy used for climate control, reducing the building's energy use by 15%.
Further energy savings are achieved through custom-built optimally-sized air handling units, variable frequency drives, and heat wheel recovery systems for the auditorium and laboratory exhaust systems. The expected energy cost savings are realized and maintained through building systems commissioning, and measurement and verification of the MEP systems.
Indoor Air Quality
Low-VOC (volatile organic compounds) carpeting, paint, adhesives, and sealants are used throughout the building to guarantee the health of building occupants and reduce environmental impacts. VOC's found in many construction items, in the presence of NOx and light from windows or photocopiers, combine to form ground-level ozone. While this much-lauded chemical is desirable in the "ozone layer" where it shields the earth from ultraviolet radiation, it is toxic and a major source of indoor air pollution.
Approximately 30% of construction materials came from within a 500 milie radius. Over 85% of the wood used in the project is Forest Stewardship Council (FSC) certified, including 70% of materials used for laboratory casework. Construction materials contain 4% post-consumer content and 14.5% post-industrial content.
Integration of Sustainability in Design & Construction Process
Duke used the USGBC LEED™ rating system as a framework in green design charrettes and feasibility studies, to define the sustainability goals of the project and prioritize possible green features. Skanska utilized a web-based LEED™ information management system called LEEDBuilder, to facilitate information sharing amongst stakeholders and submit US Green Building Council (USGBC) documentation.
