Ventilation measurements combined with pollutant concentration measurements discriminates between high emission rates and insufficient ventilation

• High local concentrations of a pollutant can be the result of high local emission rates of the pollutant or insufficient ventilation. Using tracer gases to map the ventilation in multi-zone buildings combined with measurements of the local pollutant concentration provide the means to discriminate between these causes. In a similar manner, the propagation rate of pollutants from a source to a target zone and the emission rate of the pollutants at the source may be determined quantitatively.The paper presents both the theoretical framework for the techniques and experimental examples of the proposed methods.
