Diagnosis and quantification of heating and cooling energy needs of a residential home in Algeria

These investigations aim to diagnose and measure the energy usage of a genuine residential building in the Mediterranean environment at the Tlemcen site. The method being used is based on an integrative approach to evaluate the energy performance of heating and cooling, domestic hot water production, free and internal loads connected to lighting, and equipment and occupants are not taken into account. Weather statistics are used to determine the yearly needs for heating and cooling using climatic data from 2020. To ascertain the appropriate energy cost, a technical and economic study would be of interest to us. Living in this apartment complex is therefore not affordable. The primary causes of heat loss in buildings are the ground, roof, and facade walls (more than 70% of total losses). In order to construct ecologically and bioclimatically friendly homes that fit the climate of the area, the evaluation functioned as a fundamental survey. To increase the building's energy efficiency, passive and active design elements must be integrated.
