IMPACT STUDY OF THE SOLAR ENERGY ON THE ENERGY PERFORMANCES OF THE RURAL HOUSING IN ALGERIA

The building sector, which ranks first in terms of electricity consumption for fossil fuels, is a key sector, since it allows an influence on both demands with application of the energy efficiency measures and supply with integration of renewable sources like solar panel. Especially in Algeria which represent an inexhaustible tank of solar energy. This paper presents an energy behavior study of a rural housing in three areas in Algeria. First, we evaluated the energy needs for heating and cooling of a High Environmental Quality housing which is taken as a reference house. The performances of the reference housing are compared to those obtained for a traditional one which has the same dimensional characteristics. The results showed a positive effect of the energy efficiency measures on the energy needs reduction. A parametric study is carried out to optimize the reference housing design for each area using TRNSYS: Thermal insulation, window's glazing type and wall thermal mass. These optimal parameters could reduce again the annual energy needs. Second, a grid connected PV system is proposed to be integrated on the reference housing roof. The simulation of its electrical performances is done using Homer environment for the same areas and shows very satisfactory results.
