Kincora Fire Station DULLES, VA
KTA Group, Inc. was responsible for providing Mechanical, Plumbing, Electrical Engineering and Fire Protection design for this 17,500 square foot, 4 apparatus bays (with provisions to add a 5th apparatus bay), fire station. The project was designed to USGBC LEED Silver criteria including development of an energy model. Revit 2011 was also utilized in the design of the project.
The mechanical system included a variable air volume type central air handling unit and outdoor condensing unit. Zoning was provided with variable air volume box with hot water heating coil tied to their individual thermostatic control. The hot water was provided by a gas boiler with an in-line circulating pump. An air economizer system was designed to provide additional energy savings. For normal outside air intake, a total energy recovery unit with supply and return fans was provided and all exhaust was routed through the unit and, after total heat recovery, was discharged to the outdoors. The intake air was routed through energy recovery unit to recover the heat to provide pre-conditioning prior to entering the central air handling unit. Dampers are provided for switching the system from normal operation with heat recovery to economizer mode with direct intake/exhaust. Infrared heaters and exhaust fans were provided in the apparatus bay.
