“…In the totality of countries, to recognize an object as a monument, it is sufficient to have special, cultural, scientific and other qualities that allow it to be established as a special part of the national heritage (Italy, Germany). In other countries (Great Britain, USA, France), the independent choice of "monument" is not of particular importance for protection even before the object is included in the list of protected uncommon cases of state protection being extended to it [5,[8][9][10] .…”

The article highlights the problems of exploitation of cultural heritage objects, which characterizes the subject area of the study. The classification of objects of cultural heritage and features of their definition in different countries are presented. The analysis of statistical data on cultural heritage sites in the Russian Federation, including those included in UNESCO, was carried out. The features of management, as well as the problems of monitoring the state of cultural heritage objects are considered. A separate and fundamental issue of management of cultural heritage sites is security activities, which are based on unique models formed by different countries based on their experience. A mechanism for managing cultural heritage objects in a digital environment and a universal conceptual model for introducing digital technologies into the system of real estate operation are proposed.

Energy Efficiency in Historic Architecture: The “Ex Institute of Zoology and Comparative Anatomy” in Palermo

In Italy, a large part of the buildings classified as historical–artistic heritage is in a state of degradation and requires urgent interventions. Among the needs, a reduction in the high energy consumption and an improvement of the indoor comfort are mandatory. The case study of the “Ex Institute of Zoology of Palermo” shows how it is possible to achieve a reduction in energy consumption and preserve the building’s historicity through the estimation of energy loads and the subsequent processing. To quantify the energy savings of the structure, it was necessary to follow a few steps, namely an inspection of the building and an evaluation of its consumption. To elaborate a correct energy analysis, the thermal conductance was calculated by considering measurements over a period of 60 days and proceeding with the calculation of the transmittance. The resulting data are imported in the energy model developed with the TERMUS BIM software. In the case study, a potential energy saving equal to 35% of the current energy consumption can be avoided by replacing the lamps with LED ones, installing photovoltaic panels, replacing the heat pumps with a centralized system and the current fixtures with double thermal break fixtures. These interventions are implemented in compliance with the architectural peculiarities.

“…Nevertheless, energy-saving initiatives typically exclude historical buildings to safeguard their architectural heritage. Retrofitting historic buildings was previously perceived as a potential risk to their cultural value, but this perception is gradually evolving [32]. Moreover, multiple studies have indicated notable improvements in energy efficiency for rehabilitated historic buildings in Europe, with Italy leading the way, followed by the United Kingdom, Spain [33,34], and China [35,36].…”

The current global context, marked by crises such as climate change, the pandemic, and the depletion of fossil fuel resources, underscores the urgent need to minimize waste. Cogeneration technology, which enables simultaneous production of electricity and thermal energy from electricity generation waste, offers a promising solution to enhance energy efficiency. Its widespread adoption, particularly in the European Union, where several cogeneration systems are in place, demonstrates its growing popularity. Italy alone has 1865 high-efficiency cogeneration units, contributing significantly to total cogeneration energy generation. Micro-cogeneration, specifically, has attracted attention for its potential to reduce energy waste and environmental impact. This study focuses on assessing the technical and financial feasibility of a micro-cogeneration plant using natural gas-fuelled internal combustion engines, considering different scenarios of plant operating strategies in order to optimize energy production, minimize waste, and mitigate environmental footprints associated with conventional methods. Additionally, it provides valuable guidance for policymakers, industry stakeholders, and decision-makers invested in sustainable energy solutions. By advancing micro-cogeneration technology, this study aims to promote a more sustainable and environmentally conscious approach to energy production. The methodology applied is based on the development of a numerical model via RETScreen Expert 8 and it was calibrated with one-year energy bills. The study was performed by focusing on the analysis of the annual energy savings, greenhouse gas emission savings, tonnes of oil equivalents savings, and financial parameters such as Net Present Value (NPV), Internal Rate of Return (IRR), Profitability Index (PI) and Payback time (PBT). The results show, using a micro-cogeneration system in a big complex of buildings, that the financial parameters can continually increase with the plant’s capacity with the electrical load following, but with a loss of the recovered heat from the cogenerator because it may reach values that are not necessary for the users. When the thermal load variation is much more significant than the electrical load variation, it will be useful to design the plant to follow the thermal load variation which allows the full utilization of the thermal and energy production from the plant without any waste energy and choosing a system capacity that can optimize the energy, emissions and financial aspects.
