The construction sector is a major contributor to total energy consumption, therefore, it is crucial to adopt energy efficiency strategies capable of reducing energy impact in buildings. Among these strategies, exterior wall insulation is one of the most cost-effective options to achieve energy savings for both newly constructed and renovated buildings. In this paper, based on an economic analysis, we aim to determine the economically optimal thickness of insulation material to be used for retrofit interventions of masonry structures. The study analyzes 10 different insulating materials and 5 masonry structures widespread in Italy. The results show that each masonry structure requires a careful evaluation of the thickness of the insulating material to be applied in retrofit operations. Moreover, varying the type of insulating material used, even if applied to the same wall structure, there are different levels of thickness to be applied in order to optimize the performance of the structure.

Abstract

The construction sector is a major contributor to total energy consumption, therefore, it is crucial to adopt energy efficiency strategies capable of reducing energy impact in buildings. Among these strategies, exterior wall insulation is one of the most cost-effective options to achieve energy savings for both newly constructed and renovated buildings. In this paper, based on an economic analysis, we aim to determine the economically optimal thickness of insulation material to be used for retrofit interventions of masonry structures. The study analyzes 10 different insulating materials and 5 masonry structures widespread in Italy. The results show that each masonry structure requires a careful evaluation of the thickness of the insulating material to be applied in retrofit operations. Moreover, varying the type of insulating material used, even if applied to the same wall structure, there are different levels of thickness to be applied in order to optimize the performance of the structure.
