Optimizing opening dimensions for naturally ventilated buildings

Since naturally ventilated buildings respond to site conditions and microclimate, we cannot establish a “one set of criteria” for every naturally ventilated building. So natural ventilation should be optimized to deal with thermal comfort in passive buildings during summer. A survey of existing tools for natural ventilation simulation shows the dominance of so-called “analysis” tools over “design” tools. In this present work, we will propose a new method to size natural ventilation openings based on inverse calculation, reduction of the number of independent parameters and optimization of occupants thermal comfort.
