Ensuring desired natural ventilation rate by means of optimized openings

Since naturally ventilated buildings respond to site conditions and microclimate, there is no ”one set of spe-cific criteria” for every naturally ventilated building. So natural ventilation should be optimized to deal with ther-mal comfort in passive buildings during hot season. For this aim, we will propose a new method to reduce the number of independent parameters based on an analogy with a mechanically ventilated building, then we will ap-ply an adapted optimization approach to produce an opti-mized ventilation sequence, and finally we will perform an inverse calculation to determine a series of opening heights corresponding to the optimized ventilation se-quence.
