Etude de l’efficacite energetique d’un batiment d’habitation a l’aide d’un logiciel de simulation

Abstract

This thesis presents the evolution of the energy situation in Algeria with a comparison to the situation prevailing in the United States, Canada and France. A comparative study is carried out in order to investigate the overall energy consumption by sector and type of energy and the energy policies that reflect this situation, in order to determine the initiatives that should be taken to improve the energy efficiency of buildings for both individuals and the public authorities. The passive energy efficiency measures applied to buildings are being showcased, because these measures lonely can divide the total energy demands of a building in the local weather data. The methodology of this work is based on numerical methods by the dynamic thermal simulation using the simulation software TRNSYS and TRNBuild interface. The result showed that the use of passive energy efficiency measures: the compactness of the building, the distribution of internal rooms and efficient windows with permanent sun protection and thermal insulation for the double wall with hollow brick improves energy efficiency by nearly 2/3, also the use of straw bale as a building material is the most efficient solution in heating, while the stone allows obtain the maximum benefit in term of cooling.
