Title Occupant generated carbon dioxide as a measure of dilution ventilation efficiency
Bibliographic information Aug. 1996, Vol.57, No.8, p.756-759. Illus. 8 ref.
Abstract Dilution chamber tests were carried out to test a model for estimating the rate of decay of occupant generated carbon dioxide after workers have left a work area. The slope of the decay curve was used to calculate the number of effective air changes per unit time and hence the effective ventilation rate. Tests in 34 locations showed that the number of air changes, as measured by carbon dioxide decay, was positively correlated with subjective assessment of ventilation effectiveness.
