Energy efficiency in historic buildings: a methodological pathway for improving efficiency through a digital platform

Energy performance and comfort condition improvements in buildings is a current issue, fixed by a stringent European regulatory framework that point to reduce emissions from buildings with increasingly objectives of renovation. Especially for historical built, which in Italy represents a large part of the buildings, the renovation must be face as a process, centred on the energetic profile knowledge. This article, part of a doctoral research, elaborates a methodology based on reading multiple energy datasets towards evaluating energy consumption and giving real prospects of improvements. Through the case study of Spelonga  an historical centre in the Marche region  the informative dataset of this process flows into an easy-to-consult digital platform, addressed local administrations to implement the energy governance and more awareness in the planning of the territory.
