Study of the Influence of Thermal Insulation on the Energy Consumption of Buildings in Different Climates in Algeria

The aim of our work is to conduct a study on the use of thermal insulation in the building sector. A solar prototype of the solar village built in Boussaâda is chosen to carry out simulation calculations using the Trnsys 17 software, in three different climates of Algeria (Algiers, Constantine and Ouargla). The solar prototype studied is equipped with devices allowing the use of passive solar energy with improved insulation. The simulation results of the passive systems show that the use of thermal insulation allows significant energy savings estimated at 34.48, 30.44 and 21.49% respectively for the cities of Algiers, Constantine and Ouargla.
