The cost of thermal energy production is constantly growing, on average, tariffs in the regions of Ukraine have tripled in recent years. The component of payment for heating in utility costs is the main one for most apartment buildings, but due to the peculiarities of district heating systems, residents do not have an impact on heat consumption, and there is a problem of uneven heat distribution: some rooms are overheated, others unheated. The normative documents of Ukraine indicate the installation of metering and regulation of energy consumption as one of the main measures to increase the level of energy efficiency of buildings. Modernization of heating engineering systems with the installation of thermostats and heat distributors is one of the most discussed energy saving measures at the general meeting of condominiums, which is of interest to most residents of buildings in operation. Experience shows that after the installation of such devices, the consumption of thermal energy by buildings is reduced, which leads to a reduction in heating costs. The relevance of the topic of this article is to study modern methods of individual distribution of thermal energy in apartment buildings, in particular in houses with a vertical heating system. The object of the study is an existing apartment building in Kyiv, where, starting in 2019, thermal energy distributors were put into operation. The subject of the study is the methods of heat distribution between apartments and the analysis of the practical results of the implementation of such a project in the existing serial building in Kyiv. The following research tasks were set:  collection of general information about thermal energy distributors, their types and principles of operation; analysis of the current regulatory framework regarding the problem of individual accounting of thermal energy; analysis of the method of heat energy distribution adopted in Ukraine with identification of the main problems that arise during its application; analysis of practical results of thermal energy distribution in an apartment building in Kyiv.

In the article identifies the economic essence of financial results and financial regulation of associations of co-owners of apartment buildings. The main financial aspects (budgeting, formation of structural components of the income portfolio and expenditure items, submission of financial statements of associations, participation in co-financing programs with the local budget) and economic and organizational aspects of the functioning of associations are considered. Chairman of the Board and the General Meeting). The existing forms of apartment building management in Ukraine have been studied (direct management of an apartment building, which is appropriate for multi-family buildings; building management by an association of apartment building co-owners and apartment building management by a management company). The preconditions for the creation and state of development of associations of co-owners of an apartment building in Ukraine, the region (Dnipropetrovsk region) and the city of Kamianske are analyzed. It was found that the number of associations in Ukraine has more than doubled in the last ten years, but the share in the total number of apartment buildings remains very small. The main legislative and regulatory framework for regulating the activities of associations of co-owners of apartment buildings in Ukraine is considered. The causes of occurrence and the amount of indebtedness of the population for payment for the maintenance of the house and adjacent territory are investigated. It has been established that the vast majority of the population does not pay for the maintenance of houses, primarily due to the provision of poor quality services, and not due to lack of financial resources. The main advantages of creating condominiums in Ukraine are highlighted (co-owners independently decide on house management, condominium members independently manage the common property of an apartment building and control the use of their financial resources, co-owners can earn money on joint property and spend money on landscaping, etc.) and shortcomings (difficulty in electing the initiative group and the chairman of the board, conducting financial and operational activities, ignorance of the chairmen and members of the board). The successful experience of the association of co-owners in Kamianske was studied.

In this paper the results of statistic analysis of heat consumption in apartment heating systems for Lithuania are discussed. Kaunas district heating system data are used for the analysis. Total sum of buildings involved is about 1900, including 1550 with the average heated area of 4000 m2. It has been established that real heat consumption in apartment buildings is less than the design heat demand (Fig 1), especially in small buildings (Fig 2). The distribution of monthly differences is presented in Fig 3. The difference during months does not depend on average outdoor temperature, but it could be caused by temperature fluctuations and solar radiation. It is quite important to determine the reasons of different heat consumption in buildings. For this purpose 20 dwelling houses of various design and building period, with various energy consumption problems have been selected for more detailed energy audit. Volumes of external building elements, changes in destination of premises, heated area have been estimated as well as the state of heat supply sub-station equipment. According to the data obtained, the energy consumption was determined for standard month at mean indoor and outdoor climate values. The results are compared with real energy consumption in the selected buildings and design values. It has been established that the inadequacies in exceeded energy consumption over design values are mostly caused by incorrect heated area registration and premises destination change, in a less range by absence of maintenance, eg broken outside doors, damaged roofs etc. Energy consumption in dwelling houses with design indoor temperature and normal maintenance level usually is near to the design value or less up to 10%. In dwelling houses, in which energy consumption is defined as being of less design value, some energy saving measures are applied, eg temperature in spaces is lowered up to 16°C, about half of balconies are glassed, electric stoves for cooking are installed as additional heat source. Such apartment buildings, as a rule, do not have premises of other destination. By such means near 40% of heat is saved.

Heat Meters

One of the main energy saving objectives is to find methods for metering individual heat consumption in each apartment of an apartment building. Achievements in the area of microprocessor devices made it possible to create a new type of measurement and control systems for monitoring and metering energy resources. Newly developed heat meters are the ground for fundamental changes in energy saving and energy efficiency. Apartment buildings are heated by various hot water distribution systems, for which it is not always possible to use conventional heat meters. The ambiguity related to the parameters of heat meters can adversely affect the estimation of heat consumption by each apartment in an apartment building. This paper is aimed at analyzing a new contact temperature measurement method and means used to create a system for heat monitoring and metering in an apartment building. The developed system can be used to meter energy resources of facilities distributed in a specific area, with geographic referencing to each facility. This makes it possible to remotely monitor heat energy consumption, which makes the energy consumption control system much more transparent and ensures public control. The system gathers data from a large number of users, processes data in real time and promptly responds to users’ requests based on recent developments in information technology. An important advantage of the developed system is that it can be used to anticipate emergency situations taking into account various factors, such as weather conditions and the age of buildings. Due to all of the above, the system can be used in the future not only in Russia but also abroad.

Abstract The energy sector in Romania consists of three sub-sectors: electricity, natural gas and heat. Among these, the sub-sector of thermal energy is in the most precarious situation because it has been neglected for a long time. This sub-sector is particularly important both due to the amount of final heat consumption (of over 50% of final energy consumption), and to the fact that it has a direct negative effect on the population, industry and services. This paper presents the main directions for developing a modern strategy of the thermal energy sub-sector, which would fit into Romania’s Energy Strategy that is still in preparation This is based on the author’s 50 years of experience in this field that includes knowledge about the processes and the equipment of thermal energy, expertise in the management and restructuring of energy companies and also knowledge of the specific legislation. It is therefore recommended, following the European regulations and practices, the promotion and upgrading of district heating systems using efficient cogeneration, using trigeneration in Romania, modernizing buildings in terms of energy use, using of renewable energy sources for heating, especially biomass, and modernizing the energy consumption of rural settlements.

Hospital Size

Energy use in hospitals is higher than in other public buildings, so improving energy efficiency in healthcare buildings is a significant challenge in this sector of engineering. For this, it is necessary to know the various determinants of energy consumption. Until now, the main factor affecting energy consumption in healthcare facilities studied in the literature was hospital capacity. However, the commonly used variables connected with hospital size and the number of beds do not take into account the medical activities carried out in these buildings. Assuming that energy consumption in hospitals is multiple and shaped by many factors that overlap, not only on an individual level but also on a higher scale level, this study devises a more integrated approach to its determinants. This study aims to investigate the determinants of electrical energy costs (EEC) and thermal energy costs (TEC) in Polish hospitals with regard to factors related to their size, work intensity and climate zones. The analysis was carried out using financial and resource data from all Polish hospitals for the years 2010–2019. The study used a multivariate backward stepwise regression analysis. In order to use climate as a moderating variable, a sample of Polish hospitals from 16 Polish NUTS 2 was divided into four climate zones. This article provides new empirical evidence on the determinants of electricity consumption in Polish hospitals related to their size and medical activity, taking into account climate zone as a moderating variable. The results of the analysis show that both electricity and heat consumption in hospitals are positively related to the number of doctors, beds and the number of medical operations performed. As expected, larger hospitals seem to use more energy. Moreover, there is regional heterogeneity in energy consumption in hospitals related to the climatic zone in which they operate. The conducted analysis shows that Polish hospitals located in the warmest climatic zone are characterized by higher energy consumption than hospitals in the coldest zone. It especially regards EEC in surgery hospitals. The warmer the climate zones, the higher intensity in terms of the number of surgeries, the higher EEC. In terms of nonsurgical hospitals, the influence of climate zone on EEC was not observed. Knowing the factors influencing energy consumption in hospitals can facilitate the correct adoption of an energy-saving strategy in the health sector, which is a reasonable response to climate change and supports a healthy and sustainable future.
