Full Description

When designed and operated adequately, naturalventilation (NV) can improve the buildings energy efficiency and indoorenvironmental quality. There is a plethora of factors that limit theeffectiveness of NV, such as the climate, surrounding buildings, noise, andambient air pollution, especially in urban environments. Nevertheless, theexisting NV potential (NVP) calculation methods are complex and difficult to beused. This study proposes a new methodology for quantifying the NVP byconsidering the exterior climate and ambient air pollution. This methodologyanalyzes climatic and ambient air quality data to estimate the NVP of urban andsuburban sites of 27 European cities. The results reveal that the level ofurbanization and proximity to traffic significantly influence the applicabilityof NV. Taking ambient air pollution into account reduces the climatic NVP onaverage: 11% for suburban background sites, 28% for suburban traffic sites, 22%for urban background sites, and 50% for urban traffic sites. Building designerscan use the proposed methodology in the building design phase in order toimplement the NV without increasing occupants exposure to outdoor air pollution.The results of the statistical analysis can be used by the public authoritiesand the decision-makers to better consider the limitations and opportunities ofthe NV use by the building stock.
