The concentration coefficient technique is a method for calculating the concentration field in the atmosphere in the vicinity of a building when an airborne substance is released from or near the building. The operative parameter in the concentration coefficient K which, in the majority of applications, is independent of substance release rate, wind speed, and building size, but is dependent on wind direction, building shape, source configuration, and receptor location. The prediction of real concentrations depends on one’s ability to make an appropriate estimate of K and to transform it into a concentration estimate. This paper describes available data sources for K, examines its nature, and illustrates its use by a case study.
