摘要:The construction industry has long been one of the most energy intensive sectors in the world. Therefore, the development of building materials appears to be one of the effective solutions to this challenge. Plaster is considered among the materials widely used in construction because of its advantageous properties. The present article includes in its entirety two sequential studies. The first one, deals with an experimental analysis of the plaster thermo-physical properties formed by two different mixing water rates, in order to evaluate its effect. While, the second, presents a dynamic simulation results of an individual building subjected to different climatic conditions of Morocco and in which no energy efficiency measures were carried out, through simulations series realized by using TRNSYS software. The latter study was intended to quantify the developed materials impact, on the energy required to maintain the occupants comfort. The findings obtained in this work, revealed the positive influence of increasing the mixing water rate. Thus, reducing the plaster thermo-physical properties, delaying the heat transmission, and significantly decreasing the building energy consumption devoted to heating and cooling.
