Sheridan College (Ontario)
OP-5: Indoor Air Quality

Sheridan operates the buildings air handling system as per the Ontario Building Code and controls the system using the ASHRAE 55 standards governing commercial buildings air quality. Sheridan’s air handling systems are designed according to the air handling automation system whereas the control sensors installed on the system are designed to provide self-diagnostics and adjust the air controls accordingly. In general, if the return-air sensors detect that the return air from a room has a higher level of CO2 than is mandated by the ASHRAE standards, then the system self-adjusts to allow more fresh-air to be supplied to the air-handling system supplying the room with higher-than-mandated CO2 levels. This ensures that the CO2 levels are well within the acceptable standards for human occupancy. Green cleaning products are used on campus to eliminate toxic substances and harmful fume discharges in the interior environment. Designated smoking shelters are provided in certain locations around campus to ensure a smoke-free environment indoors. These shelters are located at a sufficient distance from building entrances. Air that enters college buildings is filtered through a hospital-grade air filtration system that filters the air twice. Implementation of living green walls is seen at the HMC and Davis campuses. The living wall acts as a natural bio filter that is fully integrated into the building’s air handling system, designed to remove common indoor contaminants, and improve air quality and energy efficiency.
