Classroom Capacity Considerations Based on Social Distancing and Ventilation Guidelines
APS follows ASHRAE 62.1 and 62.2, the standards for ventilation and indoor air quality, and refers to other guidelines such as the Harvard T.H. Chan School of Public Health Guide to Checking Ventilation Rates in Classrooms. Our goal is to maximize outside air changes and ventilation in all classrooms above the recommended 5 Air Changes per Hour (ACH).
- All Direct Outside Air Systems (DOAS) have MERV-13 filters.
- Any HVAC equipment that maybe upgraded to MERV-13 has already been or will be upgraded.
- APS is providing Certified Room Air Cleaners (AHAM and CARB certified) that will provide the target minimum of 5 ACH for classrooms where equipment filters cannot be upgraded or where outside air changes do not meet standards.
- APS encourages occupants to open windows when outside conditions permit to increase outside air. (i.e., humidity levels less than 60% and temperatures greater than 50 degrees F).
