2012 Technology Award Case Studies
• All three of the building’s mechanical HVAC systems use energy recovery to minimize energy use. • To minimize the new building’s footprint, the facility’s 12 new classrooms include two pairs of classrooms with moveable walls, allowing for a large computer testing area. In addition, five conference rooms in the new facility have multi-use functions, and double as examination rooms, with an adjacent storage area for exam equipment. • An aquathermal geothermal system was used as a building heating and cooling source to the HVAC systems. • Underfloor radiant heating was provided to offset perimeter heating losses, providing superior comfort and allowing unoccupied night setback without cycling air-handling equipment to conserve energy. • Alternative transportation measures were designed as part of the project, including: bike racks for a percentage of the building occupants as well as shower facilities; preferred parking for low-emitting vehicles and the ability to walk less than 0.25 miles (0.4 km) to gain access to two bus station lines serving the surrounding metro areas. • Low water flow and automatic sensor operated plumbing fixtures were used to minimize water use. • Carbon dioxide sensors (demand ventilation) were provided in each room to reset outdoor air ventilation quantities when spaces are unoccupied. • Energy-efficient lighting, including T-8 fluorescent lamps and electronic ballasts, are used and controlled by occupancy sensors in each space. • Site water run-off is captured from the site through several retention swales and is drained into the aquathermal ponds to aid in the efficiency of the aquathermal system. • Registered with the U.S. Green Building Council, the facility is on track with points necessary to achieve LEED certification. • The photovoltaic system, located on grade near the north building entrance, was installed to generate between 15,000 to 16,500 kWh annually, representing approximately 0.73% of the building’s annual usage and 0.2% of the current annual electrical power consumption for the university’s entire campus. • The actual building’s energy efficiency far exceeds the requirements of ASHRAE/IESNA Standard 90.1-2004 by 40%. • The site was restored with native or adapted vegetation to incorporate natural habitat and to significantly reduce the need for irrigation. Where plant water was required, irrigation was supplied by the aquathermal pond. • Exterior light fixtures and interior light fixtures were strategically selected and located so as to reduce light pollution of the building site. • Commissioning and functional testing were performed at seasonal weather changes to ensure peak system operation and indoor comfort. • Indoor air quality is maintained by using low VOC paints, sealants, adhesives and agrifibers. • A green housekeeping program was implemented by the university.
