2.2 Italian Guidelines
The proposed procedure provides a waterfall model with 5 steps. As in the European Guidelines, the first step is the collection of building data (geometrical, architectonic, structural, etc.). This part will be functional to the energy assessment, which will carry out taking into account local legislation and standards [3, 4]. What kind of energy analysis performing, with what level of detail (if rapid analysis or detail as according the Italian standards UNI TS 11300:2014) will therefore be a decision of the operator (depending on the availability of resources and time), with consequent effects on the degree of detail of the output data, as already shown talking about the European case. At the end of this step, the final goal is to reach the evaluation of the Global Primary Energy (EP) of the building. Later, possible measures must be selected.
As is evident, the application of this procedure on the three case studies has led to a simple comparison of performance data, before and after, without providing elements in terms of compatibility of the historical building.
Scrolling through the pages of the Italian document, however, there are numerous ideas for a careful evaluation of the interventions (e.g. from the environmental quality assessment to comfort parameters, from restoration criteria to the suggestion of non-standard measures to improve museums). According to that, the process needs to be enriched in a more organic way, integrating those criteria that are expressed in the other part of the Guidelines, focusing more on the needs of historical buildings.
