Estimated ventilation rates and work-related symptoms in US office buildings - the base study

This paper deals with estimated ventilation rates and symptoms in office workers. For that base study the authors used the U.S. EPA data from 100 large U.S. office buildings, and assessed relationships in multivariate models between ventilation/person and lower respiratory and mucous membrane symptoms.
Findings suggest that ventilation rates above current guidelines would reduce symptoms in office workers, and that occupant density may play an unrecognized role in ventilation requirements.
