This paper aims to examine the theme of energy retrofit within the circumscribed field of refurbishment interventions on load-bearing masonry buildings built in the early 20th century. These include a remarkable share of the fabric of many European cities and, in particular, they can be found in geographical areas characterized by a Mediterranean (mild) climate. The main objective is to increase the climate resilience of the buildings by verifying the economic feasibility and the environmental sustainability of the interventions at the same time observing the specific architectural features of the buildings. We put forward alternative retrofit solutions carrying out synoptic comparisons of several technological solutions and types of materials, assisted by the use of digital tools such as BIM. In order to increase the environmental compatibility of the intervention, this article carries out a closer examination of the comparison between the employment of nanostructured, conventional – of synthetic origin –, and natural materials. The selection of the best intervention solution required the elaboration of an iterative flexible integrated process of assessment of energy, technological, economic, environmental and architectural aspects. The methodology we propose here is applied to the case study of Palazzo Utveggio (Palermo, Italy).
