Improving thermal insulation of buildings envelopes can reduce their energy consumption and related CO2 emissions considerably. Searching for new and innovative insulation materials is therefore a key challenge. This work presents a synthesis study on series of experiments showing the addition effect of different additives on plaster and cement composite thermal properties. The results obtained using the box method show a significant improvement of thermophysical properties with the increase of additives incorporation rate. From an energy and environmental point of view, the results of the annual simulations carried out for a typical building located in Meknes indicated that the use of the proposed materials has economic and environmental benefits.
