lighting The facility is sited to take advantage of natural day-lighting opportunities to provide sunny outdoor spaces and interior spaces that bring daylight deep into the building while lowering energy costs by minimizing the need for electric lighting during daylight hours. Each face of the building is tuned with respect to solar orientation. Sunshades and fritted glass are provided on east, west, and south facades to mitigate solar heat gain at fenestrations. Skylights introduce natural light at key points of the building. Occupancy sensors will automatically turn lights on and off in offices. WAter And eco-systeM QuAlity Water conservation is a primary component of the building’s resource-management strategy. Domestic water usage will be reduced by 20 percent vs. the LEED standard. Low-flow and dual-flush plumbing fixtures for toilets and urinals will reduce the sewer flow rate to 1.5 million gallons per year, which is a savings of 24 percent over the LEED-base case of 1.98 million gallons per year. building systeMs Radiant heating systems are being used for improved efficiency at the A Wing and Atrium spaces, keeping the source of heating and cooling at the floor level. Set points will be adjusted, through the Building Controls Management System “night time” settings, that will allow the university to throttle back the exhaust rates at the laboratory spaces, thereby saving on energy, equipment life span, and operating costs. Estimated energy savings: 853,601 kWh/yr, $243,091 vs. the LEED standard. LU wINTEr 2009 23
