Abstract

tThe changes in present world oblige the scientific community working on Cultural Heritage to face everyday more urgent challenges of “sustainability”. This concept refers to a very broad horizon, touchingvarious spheres: cultural, economic, social, environmental, before the purely technical and energeticones; the terms deal, in fact, with a sustainable process of conservation, renovation, reuse and manage-ment of historical architecture, where the assessment methods could play a key role, even in the earlystage process. The assessment of the environmental sustainability of historical buildings may help torecognize potential ways of enhancement. This is the main content of the article, showing results of amulti-disciplinary research on a representative case study, the huge historical complex of the Albergodei Poveri of Genoa (XVII–XIX Century), which will be completely restored and reused as a universitycampus. To highlight the increasing value of a smart renovation, the sustainability of the energy solu-tions has been analysed verifying how a good rating can be obtained, within the early design process, inthe energy performance sectors. The outcomes allow to show that better results can be reached in theenvironmental sustainability certification by means of added actions not strictly needed, but allowed. Aproposal of a methodological approach to the sustainability evaluation for historic building renovation isthe main result of the investigation. A relevant step of the assessment is represented by the comparisonof the obtained scores with calculated reference scores that do not correspond to the absolute maximumvalues. This approach helps to individuate the fields in which higher global scores can be reached byplanning smart renovation actions. The results allow also to highlight some aspects of the procedureapplication that can be improved for a more appropriate use of sustainability rating systems for thisparticular kind of heritage.
