Facilities HVAC Operations During the COVID-19 Pandemic

In the summer of 2020, the CSU Chancellors Office (CO) issued guidance on building HVAC operations during the COVID-19 Pandemic. This guidance was prepared in consultation with the CSU Mechanical Review Board (MRB), as well as incorporating specific guidance from the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) and the National Institute for Building Science. The recommendations (Mandatory and Elective) were informed by references to specific epidemiology studies to provide the factual basis of this guidance. To date, these studies show that infections occur mostly on a person-to-person basis through respiratory droplets. These droplets are produced when an infected person coughs, sneezes, talks, laughs, and sings in close contact with another person. These droplets can remain active/infectious on surfaces for a very limited period. There is some evidence that these droplets can be aerosolized on a short-range (transport) basis, but none supporting long-range transport such as through an HVAC system. Actions taken by CSU and the individuals to reduce or eliminate exposure to these activities are the most effective risk-reduction activity.

What did the Cal Poly Facility Operations team do to get our campus classrooms and academic spaces ready for population:

  • We fully implemented all mandatory model practices, and to the extent feasible, the elective model practice (excessive redesign and reconfigurations were not undertaken to implement elective recommendations)
  • Our teams implement mandatory model practices in every academic building. This began with performing an “HVAC Assessment” for every academic building to determine compliance with the HVAC Mandatory and Elective Model Practices. Any issues found that did not meet the CSU model practices were either corrected on the spot or a maintenance work order was written to track the follow-up corrections.

What did the mandatory Model Practices involve?

  • Ensure that all fume hoods are operating correctly in lab spaces.
  • Disable ceiling fans and do not allow use of pedestal or personal fans in rooms with more than one occupant.
  • Ensure final filters in air handling units are installed properly to limit air bypass (air going around the filter).
  • Do not increase total airflow or the number of air changes per hour into spaces.
  • Ensure that all exhaust fans are operational.
  • Change clogged filters and clean drip pans according to manufacturer spaces.
  • Disable Demand-controlled ventilation systems.
  • Ensure that airflow and temperature alarms are set up and communicating properly.
  • Where feasible, keep doors and operable windows open to promote ventilation when outside air conditions are acceptable.
  • Exhaust systems should run 24 hours per day, seven days per week.
  • Do not open operable windows in restrooms.
  • Ensure that all ASHRAE recommendations for HVAC maintenance and filter replacement have been implemented.
  • Maximized outside air intake to the extent that it doesn’t compromise indoor air conditions for occupants. Relative humidity should be maintained between 40-60% and indoor air temperatures between 68-72 degrees Fahrenheit when heating and 70-78 degrees Fahrenheit when cooling.
  • Program a flushing sequence for the building automation system (BAS) to operate the HVAC system for one to two hours before and after occupancy.

    • At Cal Poly we have evaluated all academic building Air Handling Units (AHU) to determine if a higher-rated filter such as MERV 13 or higher can be installed without significant redesign or reconfigurations. Those AHUs that could accept MERV 13 or higher were installed or will be installed once we receive the filter(s). This work is continous and being done on a routine basis.

      Unless otherwise noted above the following are standard discriptions of listed filters
      MERV 11: Beverage Board Frame (BBF) Pleat, 100% Synthenic Media (SM). Typically 1", 2", and 4" deep filters.
      MERV 13 or greater: V-bank, mini-pleat, all plastic construction (APC), no metal components, 100% synthetic media (SM), down stream gaskets (DSG). Typically greater than 4" in depth.
      Can Upgrade To?
      This only ask the question can it physically be done?, will the filter fit?, not will the system be able to perform adequately. This is a much harder question to answer and must be examined must closer and for each fan system.
      Need To Change?
      For MERV 11 BBF pleats, this is only based on the 6 month requirement to proactively change filters. For MERV 13 or greater filters, a time since last change was given. There are no filter DP alarms associated with these types of filters.
