Project Details

The scope of work includes the replacement of the existing water source heat pump system with air handling units for assembly spaces and individual classroom ducted WSHP units. An air-cooled Variable Refrigerant Volume (VRV) system was installed using ductless cassette type room units and the existing WSHP air distribution system was cleaned and was reused/reconnected to air cooled DOAS units for ventilation air. Water Cooled Air Handling Units were replaced with Air cooled units. Boilers were replaced and hot water was extended to all AHU’s/DOAS units. All building Automatic Temperature Controls were replaced as part of the project. The scope of work is to systemically replace the existing HVAC equipment and reuse the existing mechanical infrastructure to the fullest extent possible while providing flexibility for a future renovation project./Mechanical: The project included the replacement of the existing water source heat pump system which air handling units for assembly spaces and individual classroom ducted WSHP units.

Electrical: The scope of work included the replacement of the existing switchgear and upgrade to the existing power distribution system including replacement of power panels to support the replacement of all the mechanical equipment. Additionally the Fire Alarm system was modified based on the new HVAC equipment. The installation occurred over two summers and one school year (2022-2023).
