Potential of Natural Ventilation in Different Algerian Climates

Abstract

This study tested the effectiveness of some natural ventilation basic configurations for the thermal comfort of occupants in different local climates in Algeria. Due to the diverse Algerian climate, the study was performed during the mid-season period that includes three months of May, September, and October and the summer that includes the months of June, July, and August. The ventilation potential of the selected configurations was analysed through numerical simulation by using TRNSYS software coupled with COMIS aeraulic software. The results showed the significant contribution of natural chimney ventilation caused by a stairwell to improve occupant comfort. However; its integration requires a judicious and permanent inspection to control temperature decreases or overheating risks.
