University of Toronto - Wallberg Building Renovation (Labs) - RTU Replacement
Completion: March 29, 2018
Location: Toronto
In the late summer of 2017 the University of Toronto, St George Campus, under took a renovation of the Wallberg Building, which houses labs and classrooms for the Faculty of Chemistry. The renovation involved the staged demolition of five roof top air handling units and replacement of same with pre-purchased air handlers. In addition to the new air handling units the individual exhaust fans and exhaust stacks serving labs and fumehoods were systematically demolished and replaced by two roof-top strobic exhaust fan units with a new stainless steel welded exhaust duct distribution on the roof.
The piping work consisted of provided a new steam to glycol heat exchanger plant; a new heating glycol loop and dual pump set serving the new air handling unit heating coils; reconnecting the existing chilled water piping system to the new air handling unit cooling coils; adding two separate heat recovery piping systems with dual pumps sets recovering heat from the strobic exhaust fans and dumping the recovered heat into the air handling units; steam humidification piping to each of the new air handling units and finally the replacement of the chilled water dual pump set within the building.
