The residential built heritage of Algiers and its energy behaviour: Case study of the building number 3 flats of the Aero-habitat district

Abstract

This research work is aimed to contribute towards the development of a strategy of energy control for existing built heritage. Two components have been considered to make building designers aware of a building’s b ehaviour t owards thermal comfort and energy saving. Two parameters of design and rehabilitation of residential built heritage have been carried out, dealing with an environmental site study and energy saving. An assessment of the thermal losses of the building envelope was made to evaluate the effect of the walls and roof components, before and after rehabilitation, which allowed for the proposal of various solutions relating to the reduction of heat loss in the building. A simulation scenario has been used to reach this objective. The results obtained enabled us to show that an energy saving rehabilitation would promote the built residential heritage in Algeria.
