Sussex County Community College retained our design and construction support services for a central air conditioning system in conjunction with window and facade renovation improvements to the college’s main academic building. The 40,000 square foot building was originally built in 1927, and had undergone several renovations. This project consisted of replacing the out of service rooftop make-up air units with two new 6000 CFM packaged HVAC rooftop units for fresh air, and a VRF system with four 12 ton rooftop heat pumps (ACCUs) for air conditioning with ceiling mounted blower units (ACs) in each room (60) with individual room controls. All equipment was connected to the existing building management system via BACNET communications network. Related design work included electrical for the HVAC equipment with new panelboards, and structural for new steel dunnage for the new rooftop HVAC equipment.
