Abstract Natural ventilation (NV) is a sustainable solution to improve building energy efficiency and reduce carbon emission. In this study, we quantified the impact of air pollution and noise pollution on the NV potential at both city scale and building scale in London. At city scale, the loss of annual cooling energy saving potential due to noise pollution (8.1 kWh/m2) was found to be comparable to that due to air pollution (9.0 kWh/m2). At building scale, we selected a naturally ventilated office building in central London with two windows facing a noisy and polluted traffic road and one window overlooking a quiet and clean courtyard for case study.
