Abstract

The building sector in Algeria was influenced by French colonisation in terms of typology and materials (in particular, housing sector was the most influenced), but the local traditional architecture is full of forms of harsh climate resistance. The severe hot-dry climate regions are the most affected, due to the high temperature degrees which made the government reducing electricity and gas bills tariff by 65%. The purpose of this paper is to explore the role of passive strategies inspired from traditional architecture in hot-dry climate in affecting the energy demand (cooling and heating loads). A typical case study of El-Miniawy housing in Ouled Djellal with adapted passive strategies is analysed through psychometric chart evaluation, in situ measurement campaign and dynamic simulations (EnergyPlus), to understand its thermal behaviour and energy demand, exploring the impact of seven different scenarios with modified passive strategies and parameters. The results show that the actual design temperatures in the typical hottest days are between 30.1 °C and 35.4 °C, while the external temperature is achieving to 47 °C. Moreover, the building consumes 10.43 kWh/m2 and 19.87 kWh/m2 for cooling and heating demand respectively. It varies according to the different analysed scenarios. This study can be useful for decision makers and architects in Algeria and abroad, towards the climate-responsive design in housing sector.
