One of the most important stages of the rehabilitation process, in the case of historical buildings, is to find the best solutions that can ensure, in the most efficient and nonaggressive way, the thermal comfort inside the building. In the study of this case, the authors identified several essential aspects in determining the best practices for assuring the heat consumption in buildings declared as historical monuments dating back to the 18th century. Among these we can mention: the destination of the building (tourist purpose), the dimensions and areas with the most significant heat loss, its location in a geographic area rich in geothermal water sources, as well as the thermal level of the thermal springs. It is obvious that taking into account the location of the analyzed building, the most convenient solution to occur is the use of heat from the thermal waters that feed the baths from the tourist premises. This method, taken by itself, in the climatic conditions in Romania, fails to cope with the peak demand for thermal energy during cold winter periods. For this reason, we must also call on additional sources such as electric radiant panels, hot water pipe panels (heated water or coming from renewable sources - source temperature is approximately 55 °C) or heat pumps. From calculations resulted that in the cold periods, of the maximum thermal load required, with the best solution for using the heat from the geothermal source, can cover about 35 %. The remaining 65 % requiring the installation of additional heating systems. It has also been studied the possibility of introducing a micro-cogeneration source, to ensure not only optimal thermal parameters but also a high degree of energy autonomy. In this sense, it will be interesting to analyze, in a future paper, solutions not only from a technical point of view but also from an economic point of view.

Nowadays, in order to satisfy consumer's profits and the requirements of the environment, manufacturers strive for more ecological, modern and innovative solutions in the area of heat distribution. The paper presents the results of the examinations of the importance of information systems in the process of distribution of heat for final recipients. The main research problem of the paper was to determine the answer to the question of whether IT systems used in the process of heat energy distribution are important for the final customer. The related literature was used to prepare theoretical basis for author's own research. Next, the questionnaire survey was performed and a research tool was prepared (an online questionnaire). The on-line survey was completed by 232 people from Poland, among whom only 22 failed to fill in the questionnaire. The paper is composed of two parts. This part of the paper presents briefly the theoretical basis of the problem of distribution and used IT solutions. The results of the study were also presented: opinions of the respondents concerning the validity of the use of IT solutions in heat energy distribution. The first part of the paper contains a brief presentation of theoretical fundamentals of the concept of distribution and a reference of smart district heating networks to advances in distribution in the heating sector. The results obtained during the study in the heat energy sector were also presented in numbers compared to consumer awareness. [ABSTRACT FROM AUTHOR]

Countries around the world are concerned with securing enough fuel and energy for their national economy. At present it is important supply of buildings with energy and their efficient consumption. The economical use of energy and fuel in the nonproductive sphere consists of rationalizing energy consumption in the building and energy supply to the buildings. The most energy consumed is recording heating of buildings the reason is to cover thermal losses. The European Union is focusing on supporting the modernization and renovation of apartment buildings. The aim of this paper was to analyze the socio-economic factors and their impact on the renovation of apartment buildings. Our aim was to assess by research the current position on building insulation. Based on the distribution analysis, we identified the social factors that affect the final decision of the target segment - customers. In this paper we analyzed socialeconomic factors by statistical method - multidimensional regression analysis. The results of analyzes highlighted the key socio-economic factors affecting the renovation process of apartment buildings in Eastern European countries. [ABSTRACT FROM AUTHOR]
