LA RENOVATION ENERGETIQUE DES BATIMENTS (Logements collectifs)

Abstract

Energy security and environmental constraints are a significant challenge for the economic and social development across the planet. The building of tomorrow must be part of a sustainable resource-efficient. This home wants quality, it is sustainable, adapted to the climate and preserved of the environment. Nevertheless we must act urgently on existing buildings, to maintain the park and to prevent degradation even faster which will only exacerbate the housing crisis. Improving the energy performance of these buildings is an obvious approach: the existing building constituting a savings deposit. The insulation of buildings is clearly a key element of the overall response to this problem. To contribute to this research, we are interested in this study to the thermal characteristics of a building; located in the city of Tlemcen in the west of Algeria with a hot and dry summer, cold and wet winter. The work began with an experimental monitoring database buildup, and has made calculations of heat loss by basing all the laws and thermal regulations (see DTR) and finally we decided to made to energy renovation solutions. The final advantage is a conclusion with recommendations based on our example our existing thermal regulations limiting the neglect of this important field and to learn from the experiences
