In a partnership with Perkins Eastman, Syska Hennessy Group completed the MEP design for a new student commons for Manhattan College. The commons connects the college’s north and south campuses, and provides a modern space for student and faculty engagement, learning and recreation. The central challenge was to design the infrastructure to sustainability goals for the building while adhering to the project’s performance criteria and energy-efficiency objectives, within budget constraints and tight project timetable.

Our solution included five separate direct expansion (DX) air-handling units to accommodate fluctuating occupancy schedules and loads in the building. Areas not requiring ventilation are cooled or heated using variable refrigerant flow (VRF) units so that we only had to use three rooftop condensing units to serve multiple indoor spaces. Demand control ventilation (DCV) using CO2 sensors varies the amount of outdoor air, while all building systems are controlled by BMS. We conducted a solar study to design optimal daylight control and automated shading of the curtain wall, with override controls operated on preset positions.
