A study on the optimum insulation thicknesses of building walls with respect to different zones in Morocco

Morocco has very limited indigenous energy resources; consequently, with the increase in energy consumption over the last years, studies focusing on energy saving as well as usage of sustainable energy resources have accelerated. However, in Morocco the buildings have an important part in the energy consumption; therefore, the most logical solution is energy saving by using thermal insulation. For this purpose, in this study, six cities, namely Agadir, Tangier, Fez, Ifran, Marrakech and Errachidia are selected to represent the six zones of Morocco. Using the life-cycle cost analysis method, the optimum insulation thicknesses as well as energy savings and payback periods for electricity tariff and three different types of insulation material have been determined.
