Air Quality and Circulation

Facilities and Operations has implemented operational and maintenance inspections and procedures to ready campus for occupancy during the COVID-19 pandemic. The University has taken the following measures to increase the reliability of the heating, ventilation, and air conditioning (HVAC) systems of buildings on campus and assure indoor air quality performance, consistent with recommendations from the CDC and other government and industry associations:

  • Ensure ventilation systems in all buildings are operating properly by completing a comprehensive checklist of systems and performing inspections of all critical equipment. This all-inclusive inspection was completed for all buildings prior to the start of the 2020-21 academic year and is being repeated ahead of the Fall 2021 term. In addition, Facilities and Operations has increased the extent and frequency of preventative maintenance measures for equipment.
  • Upgrade air filters to a level efficient at capturing airborne viruses to reduce potential concentration of particles in the air (completed prior to the Fall 2020 term and remaining in place for Fall 2021 and beyond). Many air filters in place were already at or above the recommended level, and those that were not at the recommended level were upgraded. As part of regular maintenance, Facilities and Operations has also increased the frequency of filter replacements.
  • Ensure all classrooms meet industry recommendations for air changes per hour. ACH refers to the number of times that room air gets replaced every hour with outside air and/or filtered air. Measurements are taken in all classrooms, and any classroom measuring below the minimum had repairs made to the ventilation system to bring the ACH to an acceptable level. High-efficiency particulate air (HEPA) filters were installed in certain classrooms to supplement and increase the effective ACH. This effort was completed for all classrooms prior to the start of the 2020-21 academic year and is being repeated ahead of the Fall 2021 term to ensure that all classrooms meet or exceed ACH level requirements.

Please keep windows closed to allow the central systems to operate properly. If your space does not have a central air supply, follow guidelines about how and when to open windows. Do not leave windows opened unattended.
