Design of an Efficient Insulation System for a House in Zaouiat Sidi Abdeslam

The purpose of this research is to design a thermal insulating system for a residential building in renovation. Several construction techniques are being implemented to ensure the feasibility of the project in a real-life scale, and to meet the constraints of the regulations regarding construction in the region of Ifrane, more specifically Zaouiat of Sidi Abdeslam. The aim of the study is to choose the best thermal insulation scenario for the house, in terms of thermal performance, and thermo-physical properties. The insulating materials proposed are foam of Polyurethane, Cellulose wadding, Rock wool, and Glass wool. Finally, the financial analysis will play an important role in the final decision. Using a dynamic thermal simulation software, “Binayate”, the analysis of the transfer of heat happening throughout the building envelope is presented; mainly heat gains, losses, energy need for cooling and heating periods, each of the insulated components of the house, walls, ceiling, floor, and windows, including the linear thermal bridges, and real data according to the weather in Ifrane are presented, reinforcing the personal arguments on the materials and method chosen in the project to achieve energy efficiency and sustainability. From the results, Glass Wool affirmed being the best scenario, having a 63% energy reduction impact and, a 4.3 years payback period. Furthermore, its insulation permanence's is accepted by the norms of the Moroccan thermal regulations.
