Abstract
The highest challenge of energy efficiency of building stock is achieving improved performance in existing buildings and, especially, in heritage buildings which per se are characterized by massive limitations against the implementation of the most sophisticated solutions for energy saving. In Italy, historical buildings represent more than 30% of the building stock and the vast majority require energy retrofit, while ensuring the preservation of the heritage value and acceptable comfort conditions. In this context, historical buildings must be retrofitted and re-functioned by introducing innovative technologies aimed at reducing energy consumption and improving human comfort, health, and safety. To this aim, this study implements the Historic Building Information Modeling (HBIM) approach for the integrated modeling, monitoring, management, and maintenance of a novel geothermal system involving horizontal ground source heat exchangers (GHEXs) coupled to an adsorption heat pump for the energy refurbishment of historical buildings. In detail, a rural building part of a medieval complex in Perugia, Central Italy, is considered as a pilot case study. The analysis stresses the potential of the Facility Management (FM) applications of HBIM to provide a tool for the human-centric operational management control of the building energy performance and indoor comfort when combined with the building monitoring and supervision system. Therefore, this integrated HBIM approach may drive the path towards the user-centric re-functioning of heritage buildings.
Highlights
According to the recent renovation wave [1], the energy refurbishment and improvement of the European building stock is a key aspect to be addressed in order to drive decarbonization and cleaner energy systems
Holistic modelling and simulation approach as a tool for the human-centric and energy efficient the control is activated to identify the fault remotely and to efficiently restore the expected environmental operation and management of renewable energy systems integrated in historical buildings
The sheet allows, to easy monitoring of the parameters and creation of quick operation and management approach for heritage buildings is based on Historic Building Information Modeling (HBIM) and is developed warnings for anomalies
Summary
According to the recent renovation wave [1], the energy refurbishment and improvement of the European building stock is a key aspect to be addressed in order to drive decarbonization and cleaner energy systems. Almost 75% of the existing buildings in the EU (European Union), are energy inefficient and, in general, buildings are responsible for more the one third of the EU final energy consumption and greenhouse gas emissions [2] They are potentially one of the most promising sectors to be improved towards global energy efficiency [3]. Historical buildings characterize the urban space townscape, which is the built environment added value that attracts tourists’ interests. They are often protected by law for visual appearance preservation and, the integration of new materials and construction techniques into the original architecture must submit to specific requirements [4]. In Italy, for instance, which hosts a large share of EU heritage sites, about 31.5% of buildings were built before 1945 [5]
