“…A specific indicator is "Embodied Energy", i.e., the total amount of energy used to produce, transport and install a building material or component [62]. Several authors have highlighted the role of embodied energy in the choice of retrofitting historic buildings [63][64][65][66].…”

Historic buildings are at the center of cultural and economic interests, due to issues related to their conservation and protection as well as their use and technical-performance efficiency. They are often considered within the accepted meaning of ‘assets-resource’. In recent years, there has been a significant increase in the research and development of methodologies to appropriately intervene on this type of heritage assets. This contribution defines a methodology to select interventions capable of combining protection requirements with performance upgrading, as part of integrated seismic improvement and energy-environmental retrofit strategies. The aim is to develop a tool that not only supports Public Administrations in the planning/designing of appropriate interventions but also private investors in a partnership perspective. Given the need to use a multidisciplinary and multi-criteria approach, the AHP (Analytic Hierarchy Process) method has been used; it allows for the comparison of various intervention alternatives on the basis of certain evaluation criteria, aimed at obtaining a preference index. This approach allows us to support the decision-maker in making the most appropriate choice, according to a rationally structured procedure.

“…One could argue that if the historical tiles are not damaged, there is no reason to replace them, as their replacement will result in GHG emissions and a loss of heritage value. Effectively, the energy embodied in historical buildings is rarely considered in energy-retrofit strategies [31,32]. The adaptive reuse of heritage building materials can reduce GHG emission; nonetheless, historical buildings still need to be upgraded to be energy-efficient over their full life cycles [32].…”

Climate change mitigation targets have put pressure to reduce the carbon footprint of cultural heritage buildings. Commonly adopted measures to decrease the greenhouse gas (GHG) emissions of historical buildings are targeted at improving their energy efficiency through insulating the building envelope, and upgrading their heating, cooling and lighting systems. However, there are complex issues that arise when mitigating climate change in the cultural built heritage sector. For instance, preserving the authenticity of heritage buildings, maintaining their traditional passive behaviours, and choosing adaptive solutions compatible with the characteristics of heritage materials to avoid an acceleration of decay processes. It is thus important to understand what the enablers, or the barriers, are to reduce the carbon footprint of cultural heritage buildings to meet climate change mitigation targets. This paper investigates how climate change mitigation is considered in the management and preservation of the built heritage through semi-structured interviews with cultural heritage experts from the UK, Italy and Norway. Best-practice approaches for the refurbishment of historical buildings with the aim of decreasing their energy consumption are presented, as perceived by the interviewees, as well as the identification of the enablers and barriers in mitigating climate change in the cultural built heritage sector. The findings emphasise that adapting the cultural built heritage to reduce GHG emissions is challenging, but possible if strong and concerted action involving research and government can be undertaken to overcome the barriers identified in this paper.

“…Следовательно, большое внимание необходимо уделять энергоэффективным технологиям и энергосберегающим мероприятиям [1][2][3][4][5]. При проведении ремонта или нового строительства использование современных строительных материалов должно стать основной тенденцией [6,7]. Но на этапе проектирования необходимо производить точные расчеты, чтобы избежать возможного разрыва между проектным и фактическим уровнем энергопотребления [8].…”

It is known that heat-stressed elements greatly affect the thermal properties of walling and contribute to the heat losses of a building. Heat-stressed elements decrease the temperature on the inner walling surface adjacent to the external corners. In addition to increasing heat losses, heat-stressed elements increase the condensation on the inner walling surface leading to mold appearance. This is one of the reasons that shows that the modeling of heat-stressed elements is a very important design stage. The article discusses the effect from these elements on thermal properties of multilayer walling in the external corner of a building. Using the ANSYS software package, the influence of heat-stressed elements on the heat transfer processes is modeled in the external corner area. A quantitative assessment of the thermal state of typical walling fragments under extreme heat-transfer conditions is given. The obtained research results can be used to increase the temperature in the area of heat-stressed elements and reduce their negative impact.
