Good indoor air quality key to safe classrooms
The Canadian Hydronics Council (CHC) has set up a public health task force to raise awareness of the importance of proper ventilation and indoor air filtration in classrooms.
Managing indoor air quality has been identified as a possible way to stop transmission of airborne pathogens, and the task force intends to communicate this message to public health officials and school boards across Canada.
The task force will also communicate:
- The benefits of hydronic heating and cooling.
- Case studies of system applications and their impact on air quality and energy efficiency.
- The application and adoption of green energy options.
- Messaging ideas to influence decision makers.
According to the CBC’s “School boards all making changes, but taking different approaches” published on June 21, 2021, Greater Toronto Area school boards have begun upgrading their facilities with regard to air quality, but in different ways. The Peel District School Board, for example, has “upgraded all of its air filters to MERV13 (a high-end filter used in hospital settings), is operating ventilation systems for longer periods of time, and has also purchased 1,140 stand-alone ventilation/filtration units to use in classrooms and portables where the only airflow comes from doors and windows.”
Meanwhile the CBC reports that the Toronto District School Board “has HEPA high-efficiency filters in all classrooms, portables and wellness rooms,” and has “170 ventilation projects approved for this summer, with many being carried out in aging buildings.” In the York Region District School Board, “most of its schools have mechanical ventilation and upgraded filters” and the board has “put in automated systems that it says flush the buildings with fresh air each morning.”
