Evaluating the Use of Ventilation Efficiency Indices to Improve Urban Ventilation

抄録

Removing heated or polluted air is one of the most difficult tasks to accomplish when it comes to ventilating urban environments. This study is an effort to satisfactorily describe the ventilation performance in outdoors by means of ventilation efficiency indices. The ventilation efficiency indices studied were the local age of air, purging flow rate and air exchange efficiency.
