ABSTRACT
The COVID-19 pandemic has driven public interest in building ventilation rates. The ASHRAE Epidemic Task Force's recommendation that buildings "provide and maintain at least the minimum outdoor airflow rates for ventilation as specified by applicable codes and standards" put quantitative ventilation system assessments in high demand. Throughout the pandemic, many building owners conducted assessments of building systems, including ventilation, to reduce risk of COVID-19 transmission. A recent study of assessments at 95 commercial office buildings found that 77% provided minimum ventilation rates or could make minor adjustments to do so. However, 23% of buildings were underventilated and would require significant capital investment to meet current standards. All but one of these buildings were designed between 1981 and 1992, with ventilation rates as low as 9 cfm/person (4 L/s person) (assuming default occupant density).
