natural ventilation potential

When designed and operated adequately, natural ventilation (NV) can improve the buildings’ energy efficiency and indoor environmental quality. There is a plethora of factors that limit the effectiveness of NV, such as the climate, surrounding buildings, noise, and ambient air pollution, especially in urban environments. Nevertheless, the existing NV potential (NVP) calculation methods are complex and difficult to be used. This study proposes a new methodology for quantifying the NVP by considering the exterior climate and ambient air pollution.

The world urban population is expanding, resulting in taller buildings and increased building density. This paper describes a design approach for the natural ventilation of high-rise buildings based on a double façade structure in which an external cladding is used in conjunction with a central air-well with wind catcher ("hood").
