Ventilation & Air Conditioning Systems

During  the first two phases of the campus reopening plan, the HVAC (heating, ventilation, and air conditioning) in all research and regularly occupied buildings continued to operate on their normal schedules. Other buildings that experienced reduced or no occupancy have had their building HVAC systems operate at a minimum of one hour per day to ensure regular ventilation of the facilities. Prior to occupancy, each facility that has been hibernated will have the air systems operated in a purge mode for at least 48 hours prior to occupancy. Additionally, all recirculating air systems will be verified for proper filter fit and to the extent possible will be outfitted with MERV-13 final filters. Note that most campus buildings already meet this MERV rating. Air systems that have scheduled operation will have a daily pre- and post-occupancy purge.
