Kilgo Residence Hall (Phase II)
Kilgo Quad was the first LEED™ certified residential renovation at an American university. Kilgo, along with the adjacent residence halls are on known on campus as "The Gothics" for their architectural style, and collectively house 68% of Duke's undergraduate students. Renovations on Houses I & J (Phase II) were carried out over the summer of 2002 while Houses N, O & P (Phase III) were renovated over the summer of 2003.
Sustainable Site Features
Kilgo has the capacity to house 390 full-time occupants who, unlike in academic buildings, require energy and resources 24 hours a day. Thus, efficiency improvements in Kilgo and the other "Gothics" have a significant effect on Duke's carbon footprint. The 1920's gothic construction and mature landscaping constrained sustainable site features in some aspects of design.
Low-flow faucets and showerheads were installed in all bathrooms. Kilgo observed an initial 35% reduction in water consumption.
A Siemens Direct Digital Control (DDC) System allows the Facilities Energy Manager to control the allowable range of individual room thermostats (currently 66° – 78°F). HVAC systems and duct work were upgraded with heat recovery ventilation to eliminate the need for opening weatherproofed windows.
Indoor Air Quality
Use of low-VOC paints and carpeting improves indoor air quality. As part of the renovation, student common areas and alcove areas were added, increasing to 90% the portion of indoor space that receives direct sunlight. In addition to reducing the energy expended on artificial indoor lighting, natural daylighting is shown to increase the comfort of buildings, particularly residential spaces.
94% of all the new wood in the building is Forest Stewardship Council certified. More than 50% of construction debris was recycled.
