Parametric Study of Thermal Renovation of an Administrative Building Envelope in Region of Chefchaouen (Morocco)

In this paper, we present a parametric study of renovating the envelope of an office building located in the region of Chefchaouen (Morocco). This renovation consists of insulating external walls and roofs and integrating passive techniques. In this perspective, we modeled the building’s envelope as a multi-zone building in TRNSYS and we adopted a scenario of occupation for this type of building. Many solutions of insulation and integration of passive techniques are proposed and tested. The optimal solution chosen, verified the Moroccan thermal regulation and would cost approximately 154,022.26 MAD (15,640.60 USD) excluding VAT. The total conditioned area is about 393.6 m; thus, the renovation would cost 391.31 MAD/m (39.73 USD/m).
