Tidewater Community College and the City of Virginia Beach partnered to create a unique joint-use library to deliver more services to the TCC campus and to the entire Beach community than either organization could deliver separately.  This USGBC LEED Gold facility includes computer labs, group study areas, public meeting rooms, office spaces, a coffee shop and a dynamic children’s area.  The mechanical system is a variable-air-volume (VAV) system serving series fan powered terminal units with hydronic reheat coils.  Each air handling unit includes an enthalpy wheel to reduce sensible and latent loads during heating and cooling operation.  Chilled water is generated by two rotary screw chillers with each chiller sized for 100% of the block cooling load.  Two cooling towers and two condenser water pumps provide heat rejection for the chillers.  Chilled water coils in the air handling units are served by two variable-speed pumps in a variable-primary pumping arrangement.  Two gas-fired boilers provide hot water for the building.  A central building automation system allows control of the mechanical systems locally and remotely through the existing college network.  The control system includes monitoring of the electrical lighting and power systems as well as extensive data collection, archiving and trending.  The lighting system includes high efficiency fluorescent and LED lighting with daylight harvesting and dimming control to take advantage of the natural light during daylight hours.  A 250kW diesel generator provides backup power to the critical life safety loads as well as the telecommunications equipment and elevators.
