While the historical part of the residential stock is profoundly rooted in the local traditions and adapted to the climate of the region, the development of the newer building typologies, that currently constitute the majority of the extant buildings, has been drastically shaped by different international influences starting form the 20𝑡ℎ century. The study is part of a research conducted mainly by means of bottom-up energy modelling and simulation. The methodology involves the identification of representative typologies that can be modelled in detail and be assigned a statistical weight to typify the behaviour of the entire stock. Different sets of simulations can then predict the performance of the entire stock in in different scenarios. Preliminary results indicate a significant potential of relatively simple retrofit interventions to reduce energy use and, more in general, the environmental impact of the construction and demolition industry in the province.
