The article presents issues related to the possibility of improving the energy efficiency of historic buildings. This group of buildings, in Poland, currently has no defined requirements for minimum energy demand values. However, taking into account the long-term strategy of decarbonization of Europe and the Long-Term Strategy for Renovation of Buildings adopted in Poland, it is necessary to develop models and procedures for thermal modernization activities of historic buildings. The group of historic buildings represents a very large potential for possible energy savings in the construction sector. The article presents proposals for a system approach to achieve the standard of a historic building with near-zero energy demand and climate neutrality. Developed algorithms of procedure are presented, which can support the decision-making process in the selection of optimal thermomodernization measures.

“…This is happened above all in the countries where there is a large number of this kind of building and therefore, they impact on the achievement of the sustainable development goals (SDGs) of the 2030 Agenda. For instance, this can be seen in Italy, which owns 4.7% of the world's architectural heritage and where this one represents 46% of the entire country, or also in many other countries of the Mediterranean area [3].…”

The performance redevelopment of Architectural Heritage is a current research topic, in particular for the impact on energy saving and, consequently, on the comfort management of historical buildings. In order to evaluate the energy performance of the built environment and to optimize it in the retrofit, the way of using the heritage structures is fundamental. In particular, the retrofit in religious buildings through the installation of a new heating system often modifies the original microclimate of the internal environment without guaranteeing adequate comfort conditions, due to the peculiarities of these artifacts way of use and to their geometric and construction features. This contribution illustrates analysis on the internal comfort of a church after the retrofit intervention, which has shown energetic and comfort critical issues in relation to the discontinuous use type of the structure. The results of the analysis on the case-study, the church of San Vito in L’Aquila, have shown that the use of systems that exploit the thermal mass is not always sustainable and that it is before essential to in-depth investigate the fruition mode of the environments in order to identify suitable retrofit strategies.

“…Therefore, insulation of external walls from the inside or thermal insulating plaster can be considered [15,16]. Internal insulation of outer walls allows a reduction in the heat transfer coefficient, similarly to insulation from the outside, but if it is implemented incorrectly, it can cause problems with moisture in the walls and thermal bridges [17,18]. Thermal insulated plaster, which is the outer layer, does not cause such problems, but the achieved improvement in thermal insulation is less.…”

The article presents the results of measurements of selected thermal, moisture and mechanical properties of thermal insulating plaster, which is one of the alternatives to traditional methods of retrofitting the walls of buildings under conservation protection. An insulating plaster based on perlite was tested. Its thermal conductivity, vapor permeability and compression strength were determined. Images of the tested plaster under the microscope, at a magnification of 10-45x, were also taken. Through computer simulations, the possibility of improving the energy efficiency of an educational building by applying a layer of such plaster on external walls was determined. Changes in the heat loss structure were analyzed, and the obtained results were compared with the effectiveness of reducing heat loss through the walls using a traditional thermal insulation material. It turned out that the thermal conductivity coefficient of the tested plaster obtained by measurement was 0.0877 W/(m∙K), which confirmed the value declared by the manufacturer. Application of thermal insulating plaster with a thickness of 5 cm on the walls of the analyzed building, with other partitions of good thermal quality, reduced its energy demand by over 20%.
