The European built heritage is strongly characterized by “historic buildings”. This built heritage represents an important cultural resource, constitutes a public good and testifies the community identity. The current challenge to reduce the consumption of energy resources is aimed at the requalification of this built heritage. To meet this challen...

... the end, it was set 0.8 as average air change rate per hour (ACH) and 0.2 as infiltration rate (h −1 ). A calibration was based on the comparison between operational energy rating (OR) and tailored energy rating (TR) to assess the electricity consumption in the current state only for the first floor of the Building (Table 1). Another calibration was based on experimental data collected during a monitoring campaign with microclimatic station (LSI -Lastem) from 7 to 14 June 2019. ...Citations
... In this framework, any energy retrofit should be addressed through a systematic approach to facilitate the proper improvements. In the last decades, building energy simulation is used to evaluate in advance the effectiveness and suitability of interventions (Lo Faro et al. (2021)). More recently, this tool is used to assess the impact of interventions from both conservation perspective and thermal comfort of the users (Coelho et al. (2019); Frasca et al. (2019aFrasca et al. ( , 2019bFrasca et al. ( , 2021; Mancini et al. (2016)). ...
Energy efficiency in the built environment is gaining ground due to policies to mitigate climate change impact. This contribution focuses on investigating the role of Key Performance Indicators (KPIs) that can be useful for the energy retrofit of historic buildings. The KPIs were hinged upon PESTEL domains (Political, Economic, Social, Technological, Environmental, and Legislative) in order to define objective and measurable criteria that allow for a comprehensive evaluation of an energy retrofit performance. A literature review carried out through the PRISMA flow chart allowed to select 59 papers, subsequently analyzed to investigate the occurrences of the selected KPIs. The findings showed that the political domain is the less considered, differently from the legislative one, whose KPI highlighted the importance of being compliant with regulations. The domains representing economic, social, technological, and environmental KPIs are mostly present together in the scientific literature, underlining the importance of a holistic and multidisciplinary approach. Future research should be oriented towards delineation of best practices to meet sustainability and conservation needs, and to better integrate current policies and international requirements.

... From the nineteen publications considered in this paper, nine were from scientific journals [21 , 28-35] , one is a book [36] and nine are part of the proceedings of scientific conferences [37][38][39][40][41][42][43][44][45] . ...
... The thermal and energy analyses through the BPS of existing buildings presented in the analyzed sample were developed, mostly, with the aim of guiding possible interventions, providing better thermal comfort, and providing energy savings and sustainability. Several types of buildings were studied, such as schools [21 , 28 , 31 , 36] , offices [38] , commercial centre [34] , housing [32 , 35 , 39 , 44 , 45] , farm structures [33 , 43] , library [42] , barracks [30] , and historic palaces currently used as public building hosting offices [41] , museum [40] and, a set of services such as museum, library and conference room [29 , 37] . The simulation results for the proposed renovations were found to be independent of the buildings' usage. ...
... Other limitations pointed out were the failure in laser scanning of parts of the building [30] and the difficulty to gather all the historical information and details collected during the research [36] . From the modeling point of view, the authors also report difficulties with complex geometries, which had to be simplified and some dimensions estimated, so that the model could be completed [41] . Usually, when facing geometry-related issues, manual corrections are required [54] . ...
Building performance simulations are a complex process, especially when applying to buildings of historical interest. This paper proposes a Systematic Literature Review to investigate how Historic Building Information Modeling (HBIM) and Building Energy Modeling (BEM) can act as effective computational simulation tools and how their association has been practiced. The study selected 19 relevant publications from the period between 2012 and 2022 to identify the most frequently used software tools, data exchange, and input and output variables for thermal and energy simulations. The review found important research gaps, such as the need for better interoperability between HBIM and BEM simulation tools and the collection of accurate physical data on historical buildings without causing structural damage. The study highlights the need for better integration between HBIM and BEM resources to increase workflow speed and reduce the need for data transfer.
