Location of air intakes to avoid contamination of indoor air: a wind tunnel investigation

The location of air intakes is of prime importance in buildings that are si tuated in close proximity to busy urban roads. If intakes are placed where the concentration of traffic pollution is high then indoor air concentratio ns can reach similarly high levels. This paper presents the findings from a wind tunnel investigation into the dispersion of a simulated traffic pollu tant in a 1:100 scale model. The concentrations at different points on a bu ilding in the model are measured and a comparison with full-scale data is m ade. (C) 2000 Elsevier Science Ltd. All rights reserved.
