Mechanical Systems

As the general mechanical contractor, Kelson was responsible for the entire mechanical package including fire protection, insulation, sheet metal, building automation controls, and lab air controls. The building features a basement mechanical room containing the eight air handling units that provide ventilation throughout the building. Steam and chilled water services from York University’s central utilities plant enter the building via a service tunnel. The incoming steam services the glycol heating and hot water heating systems through shell and tube heat exchangers and generates potable and non-potable water at semi-instantaneous water heaters. The steam also serves air handling unit humidification and lab sterilizing and glass washer equipment. Laboratory services include reverse osmosis, compressed air, vacuum, CO2, argon, and natural gas. The associated equipment is located in basement mechanical rooms. A total of nine Strobic exhaust fans mounted on the roof provide laboratory exhaust air to lab areas and fume hoods. A series of rooftop fans provide general exhaust from other areas of the building.
