Energy Efficiency in the Envelope of Existing Building Case of Study "Research Laboratory of Abou Baker Belkaid”

Abstract

The world is in perpetual evolution, this evolution is due to the man in order to obtain a comfort and to facilitate his life, he comes to consume a lot of energy, thus causing an environmental degradation. The most energy-consuming sector is the building sector, which accounts for one-third of the total world consumption, and this exponential consumption reflects the need of the human being in terms of comfort. The more we consume, the more we release greenhouse gases and the more our bills go up; be it energy consumption bills or the ones we pay on taxes that have recently been put in place for governments with a high rate of CO2 emissions. So to reduce these bills, we must reduce our consumption, and for this we must improve the way we consume while keeping this comfort of which we can not have passed. Since the building sector represents a large volume of energy demand, by improving it we will have a great opportunity for economic gain. The choice of the theme was developed following the new regulations created in Algeria in the field of energy efficiency, we have taken a state building for example to follow in this sector. Among the tools of thermal analysis in the building in Algeria we have the DTR C3.2, C3.4 and C3.31, which include complex mathematical equations as part of the energy audit. The CT-BAT application is an application based on its regulations, we chose it for our work in order to obtain a detailed analysis of the thermal functioning of our case study, we will then propose applicable solutions for the compared with the existing and bring out feasible proposals and at different costs.
