Dynamic simulation comparative study of energy needs for smart positive building using concrete blockwork and clay

In this paper, we first will report on the global situation regarding energy efficiency within buildings in Morocco, a promising sector that allows a real progress in many terms. Thereby we will take an interest in the flow of thermal energy for energy efficiency. For this we will use modeling tools such as TRNSYS to analyze energy efficiency gain from building materials. Then we will simulate the behavior of the building in two different scenarii while acting on different parameters using concrete blockwork and low cost local Clay based mixture. In addition we will show the impact of these parameters in the annual energy balance.
