Facilities: HVAC and Ventilation
The Vanderbilt University Facilities Department, in alignment with the guidelines released by the Centers for Disease Control concerning building system operations to stop the spread of COVID-19, as well as guidance from the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, is committed to providing the safest environment for students, faculty, staff and the entire Vanderbilt community.
The guidance from these sources is very similar and falls into three basic categories:
- Increasing the amount of outside air being delivered to spaces
- Using high-efficiency filtration in systems that circulate air around large numbers of spaces
- Maintaining temperature and humidity levels within spaces
The university is implementing strategies to comply with these guidelines. The Facilities Department is also working to implement an overnight cycle during which buildings are flushed with an increased volume of outside air without exceeding the heating and cooling system capacities.
The Facilities Department will continue to adhere to ASHRAE published guidance for safe and healthy buildings, which emphasizes increased fresh-air ventilation and close management of indoor air quality, temperature and humidity.
To keep the Vanderbilt community as healthy as possible, indoor conditions will be maintained at temperatures ranging from 68 to 76 degrees and relative humidity of 45 to 50 percent.
Although the university is implementing these extra safety measures, it is up to each member of the Vanderbilt community to practice physical distancing, washing or sanitizing hands, and using face masks/coverings in all public spaces on campus to limit the spread of COVID-19, as recommended by the CDC.
