Evaluation of Thermal and Energy Performance of a Primary School in the Mediterranean Environment

The building sector accounts for 30–40% of annual global energy consumption, and this percentage keeps on increasing with the needs and demands of humans. The building envelope it’s a crucial factor to reduce the building energy demand, especially in heating-dominated climates. Hence the need to choose the appropriate construction materials is more important because of the desire of the inhabitants to ensure thermal comfort. This theoretical work focuses on the thermal aspect of the design of the building envelope and the type of glazing to determine the best configuration for the energy efficiency of the building of a primary school located in the city of Ain Temouchent (Algeria). By studying, monitoring and analysing the nine configurations, we applied in the building envelope in terms of energy and thermal comfort. The numerical simulations were implemented using the TRNSYS thermodynamic simulation programme. The results show the second case is the best solution in terms of consumption. Moreover, it is the simplest and the cheapest. But using the eighth case with some modifications might be better.
