Abstract


This work is an experimental study focusing on the relationship between street morphology and thermal storage in buildings. The first aim of this study is to reduce air conditioning usage in hot and arid areas, taking as example Biskra city (Algeria), during the long summer period (5 months), by reducing thermal storage. This leads to the reduction of carbon emissions to a level higher than the individual construction level in order to design a sustainable city, using measuring instruments (kimo HD 100 and Cason CA 380), we measured outdoor air temperature, wall temperature, relative humidity and wind speed on three street morphologies ; the (canyon, dihedral and open streets). These streets are different in terms of morphological indicators such as Sky View Factor (SVF) and albedo materials (a). We also applied mathematical equations across the thermal balance to calculate thermal storage. Our second goal was to identify the morphological indicators of the streets affecting the thermal storage of buildings. In this context, the obtained results showed that SVF was the most influential parameter on the heat storage.
