In just a couple of weeks, the Sigma Nu Fraternity House at North Carolina State University will be complete. Furniture arrives mid-December and will be waiting for the guys to move in during the first week in January, just before the start of the Spring semester.
One of the features of the house is the mechanical system. Each resident will have control of his own thermostat. A variable air volume (VAV) box is dedicated to each bedroom. A roof-mounted chiller sends cold water to three large air handlers (one in the mechanical room on the ground floor and two on the roof). The air handlers send cold air via ductwork to the VAV boxes throughout the house. Two boilers send hot water to each VAV box. The thermostat tells the VAV box how to mix the temperature for that room.
An overall Building Management System keeps track of these systems and can shut them down or ramp them up as demand requires. This entire system is much more efficient than a conventional split system type of arrangement common for these houses.
Completion date is scheduled for mid-December of 2013. For more information on the project, please check out our Website.
