Some solar passive concepts in habitat through natural ventilation case study: Dry climate in Algeria Ghardaia

The main objective of this paper is to study the effect of one of the most important negative concepts through natural ventilation as an economical solution and an inexpensive health phenomenon. Ventilation of buildings is a commitment and requires a minimum of flue that must be guaranteed to avoid discomfort. Air leakage in heated space increased incoming flow rates. Therefore, the leakage in the envelope building plays a major role in thermal losses. Loss created by air exchange system. So experts stressed that opening and closing windows provides a way to control the outside air in all cases. Through the daily programming schedule by climate and region, for example Ghardaia. The area of Ghardaia features characteristics of a high temperature zone especially for the months May to October. This period is characterized by climate and is often hot and in our case with habitat to strong thermal inertia of it can generate discomfort. In this case the thermal inertia is not suitable. Therefore, no other solution of ventilation night becomes more important in hot weather.
