Return to campus
Throughout York University’s response to the COVID-19 pandemic, York has remained focused on the health and safety of our students, faculty, and staff. This commitment has never wavered and remains the guiding tenet as the University implements a carefully planned and measured return to its campuses.
Planning efforts for different spaces on campus
Laboratory Space – 100% Fresh Air
Laboratory areas were designed to ensure the containment and exhaust of airborne particulate by operating in negative pressure to surrounding areas and allow no air recirculation. The labs are designed to a higher standard of Air Changes per Hour (typically labs are 6 to 12 ACH) to purge the laboratories of any harmful airborne vapours, contaminants, and particulates.
- Building air is being purged on a continuous basis. The laboratory ventilation runs 24/7 removing residual impurities generated by occupants.
- Disabling of heat recovery wheels (where possible), to help prevent the re-entry of contaminants.
- Local recirculation units such as fan coils have been disabled (where possible) to avoid the constant recirculation of air within a room. In some instances, local air distribution will need to remain in operation; for those areas a reduced level of occupancy will be recommended to reduce the potential of occupant-generated particulates.
Office, Classroom Mixed Use Spaces – Recirculated Air
Classrooms, offices, and mixed-use space are designed with a portion of fresh air, and a portion of recirculated air. The amount of fresh versus recirculated air can vary, but with peak heating or cooling seasons, the equipment is not designed to accommodate full fresh air. A central Air Handling Unit typically serves multiple floors (10,000 sq. Ft. to 60,000 sq. Ft.).
- Filtration material being upgraded to a higher quality filter.
- Air filters are changed with increased frequency.
- Ventilation is purged two (2) hours prior to scheduled occupancy and two (2) hours after scheduled occupancy.
- Ventilation is turned off during the cleaning of floors and hard surfaces to allow airborne particles to settle. Cleaning takes place only after spaces have been completely vacated and after the ventilation has been cleansed.
- Recirculation units such as fan coils and/or entrance heaters have been disabled (where possible), provided this action does not jeopardize environmental conditions. Airborne particles are decreased when fan speed/volume of local recirculation units are reduced.
- Overriding the air control to allow the maximum intake of fresh air that the equipment can handle.
- Limiting airborne contaminants by reducing the number of occupants in a building and maximizing the distance between areas of high occupancy. E.g. Allowing only 400 people in an area with a system that is designed for 2,000 people. This lessens air contaminants and significantly dilutes the level of recirculated air five (5) times more compared to normal operation.
Led by Stewart Evan Dankner (Director) and Peter Colasante (Manager), Corrective Maintenance is responsible for the maintenance of campus buildings including heating, cooling, electricity, water, elevators, keys and locks, roofs, windows, floors and doors, minor furniture repair, plumbing, lighting, ceiling tiles, carpets, painting, and carpentry.
- Installing LED lighting for all exterior lights.
- Retrofitting interior lighting with LED lights.
- Scheduling all fans on campus to save energy during non-use times of day.
- Scheduling lighting levels throughout the campus during non-use times of day.
- Upgrading to high efficiency mechanical equipment when equipment becomes obsolete.
