Thermal Performance of a Residential Building in Ben Guerir City: A Comparative Evaluation for an Optimized Thermal Load Needs

Energy demand within the residential sector represents a fairly large percentage at 25.4%, which exceeds 1/4 of the total energy consumption. In this regard, decreasing this consumption is to be preferred in order to align with the Moroccan strategy for energy efficiency. Houses, which have low consumption, can be very auspicious. The goal of this project is to design two types of small low-energy two-storey houses with an area of 35m2 each, taking into consideration the weather and the climatic characteristics of Ben Guerir city and later compare the results with respect to a conventional one. First of all, we will present an overview of the passive strategies of the building's energy. Then, this data will be used to propose two configurations of energy efficient homes. Furthermore, we will carry out the thermal study of these two houses along with a standard one. Our goal is to undergo a thermal analysis of three residential buildings with a Dynamic Thermal Simulation software DESIGN BUILDER. We’ve found that the conventional house doesn’t respect the requirements underlined by the the Thermal Regulation for Construction in Morocco (RTCM). However, the two other proposed conceptions abide by the regulations. This comparative study showcases that accurate building materials combined with passive strategies with respect to local climatic conditions can help reduce significantly thermal loads inside the houses.
