Ventilation of buildings in urban areas may result in high internal concentrations of traffic pollutants if air intakes are positioned where external concentrations are highest. This paper presents the results of a wind tunnel study into different wind-driven natural ventilation strategies for a building situated close to a busy road. Measurements of the concentration of a simulated traffic pollutant inside and around the building illustrate that noticeable reductions in internal concentrations can be achieved if air intakes are placed at roof level or on the leeward face of the building.
