Multi-criteria optimization analysis of external walls according to ITACA protocol for zero energy buildings in the mediterranean climate

A method for the design of new low-cost residential buildings will be defined; in particular, the final aim is to determine not a single optimal solution, but a set of possible external wall configurations among which the designer can choose the proper solution for his application, according to the Pareto front of the multi-criteria problem. The results underline that, in a warm climate, the best sequences of layers are with high surface mass for the first layer (internal side), followed by common insulating materials for the middle layer and eco-friendly insulating materials for the outer layer.
