AB The transformation of existing buildings into Near Zero Energy Buildings or even positiveenergy buildings remains a major challenge. In particular, historic buildings are an important culturalheritage that, in most cases, may be rehabilitated and reused for new purposes. However, achievinghigher e ciencies in those buildings presents many di culties, since there is a need to preserveaesthetic values and minimize impact on the buildings’ initial construction. In this work, a roadmapthat allows rehabilitating a building from the eighteenth century is developed, turning it into alandmark building, to be used as a museum in the near future. The procedure is based on 3D modelsusing REVIT software and detailed energy simulations supported by a cost-optimal methodology.The results reveal how conventional methodologies shown in the literature may improve the energyperformance of the buildings during the heating regime, but performance may deteriorate duringthe cooling season. For that reason, the present study includes the design of a night ventilationsystem which allows not only solving this problem but also to reducing the cooling demands by morethan 43% with little additional costs. In conclusion, historic buildings (which traditionally have ahigh thermal mass) have increased thermal storage potential by using the structures of the buildingsthemselves as well as passive cooling techniques.
