Ventilation and HVAC Upgrades in HDSB Schools
The HDSB has been upgrading school heating, ventilation and air conditioning (HVAC) systems as part of our regular renewal plan over several years. The HDSB takes a proactive approach to its HVAC systems, and ventilation systems are regularly updated or replaced. The HDSB maintains a comprehensive preventative maintenance program for HVAC equipment to ensure ventilation systems are in good operating condition and required repairs are identified and promptly addressed.
School Ventilation Measures Report
School boards are optimizing air quality in schools through improved ventilation and filtration. Implemented measures are dependent on the type of ventilation and feasibility within the context of school facilities and related building systems. This is a key element in the multiple protective strategies being employed to reduce the risk of COVID-19 transmission and support healthier and safe learning environments for students and staff.
Measures to Help Reduce Transmission Risk in Indoor Settings
Increasing the flow of outdoor/fresh air for diluting the concentration of any infectious particles.
Involves the use of different types of fibrous media designed to remove particles from the airstream.
Increased fresh air in schools by running ventilation equipment longer (pre and post occupancy air flushing), disabling energy recovery and efficiency technologies, and opening windows.
Upgraded all mechanical filtration to MERV-13 filters and changing every two months.
Install stand alone HEPA air purification devices in classrooms and other spaces that have limited pre-existing mechanical ventilation.
Upgraded mechanical ventilation systems in classrooms, gymnasiums, libraries, and portables using funding from CVRIS, school renewal, school condition improvement, and other board resources.
