Climate change and sustainable energy use is one of the five long-term objectives of the European Union. The first stage of the activities involving the implementation of this task is to reduce energy consumption of buildings to a minimum by 2020 and, in the case of public buildings by 2019. The purpose of this article is a search for the optimal way of bringing the energy performance of an existing school to a level that enables implementation of the objectives of the European Union energy policy. An analysis of the current condition of the existing school building has been carried out and options of its deep thermal upgrading has been proposed to adjust each parameter the energy performance to current guidelines specified in the technical conditions. One of the possible ways to improve the energy efficiency of the school is the use of renewable energy sources as a means of improving energy characteristics in terms of primary energy PE, the other one - optimization of renovation spending.

In the members states of the European Union, portion of buildings in the total consumption of energy represents 40%, and their portion in CO2 emissions fluctuates around 35%. The European Union is trying to protect the environment by reducing energy demand and releasing CO2 emissions into the air. Energy performance is the quantity of energy, which is necessary for heating and domestic hot water production, for cooling and ventilation and for lighting. Based on results of energy performance, individual buildings are classified into energy classes A to G. A global indicator (primary energy) is the decisive factor for final evaluation of the building. The new building must meet minimum requirements for energy performance, i.e. it must be classified to energy class A1 since 2016, and to energy class A0 since 2020. The paper analyses effect of the use of different resources of heat in a family house designed according to requirements valid since 2020, and its subsequent classification into an energy class.

The communal heat power engineering of Ukraine and its main area - the heat supply of the settlements of Ukraine - is the main consumer of primary energy resources (more than 60% of the total energy balance of the country, mainly imported natural gas). At the same time, this sector has the greatest potential for energy saving if measures and mechanisms are used to increase the efficiency of energy use, first of all with energy supply in buildings (thermal losses here reach up to 40%). Low energy efficiency of heat supply is the main reason for high tariffs for the consumer of housing and communal services and the challenge of social tension. Increasing energy efficiency is a basic condition for national economic, environmental and social stability, a requirement for the safety of life and a guarantee of the entire national security of the country. An overview of technological, organizational and socio-economic innovations for increasing energy efficiency of buildings is presented. Innovative equipment and technologies for increasing the energy efficiency of buildings and innovative engineering systems for their energy supply have been carried out at ITTP NAS of Ukraine. The method of determination of energy efficiency indicators of buildings, enclosing structures of buildings and the practice of conducting energy audits with the use of such diagnostic center measures as demonstration building of the "zero energy" constructed on the territory of ITT of NAS of Ukraine with energy supply from renewable energy sources (heat of soil, insolation, wind). Such a demonstration facility serves as a scientific and methodological center for training students of heat energy specialties, as well as the training of specialists involved in the development of energy efficient energy supply technologies for buildings and their energy audit. On the problems of increasing energy efficiency of the building sector in the near future, the main objectives of scientific research, subjects of fundamental, applied research, subjects, methods and tools of such research were determined.

Improve Energy Efficiency

Modern agriculture is dependent on external energy sources. Non-renewable energy sources play a dominant role, which contributes to greenhouse gas emissions and, as a consequence, to environmental degradation. Therefore, it becomes obvious to strive to improve energy efficiency and change the structure of its sources. One of the main research goals was to determine the economic and energy efficiency of agriculture in EU countries and assess its energy consumption by analysing energy consumption per employee or 1 ha of utilized agricultural area. The work analyses changes in energy consumption in agriculture of the European Union and its members. Eurostat data was used for the analysis.

The paper addresses the problem of energy sustainability of European Union countries in terms of renewable energy sources, energy consumption levels as well as energy dependency and energy intensity of the economy. The aim of the study was to identify and assess the key characteristics of the energy sector of EU members states between 2006 and 2016 using taxonomy, which is one of the basic tools in a multi-dimensional comparative analysis. The analysis revealed that, despite common challenges, different member states showed varied levels of the implementation of EU climate and energy targets. In terms of the approach to the production and consumption of primary energy, EU countries can be divided into two groups. In most Western European countries, energy production is mainly based on renewable sources. However, it only meets a small portion of the domestic economy’s needs. In contrast, Central Eastern European countries are characterized by greater concentration on aspects of self-sufficiency and security of own energy systems. In such countries, the share of renewable sources in overall energy generation is smaller.

Energy Poverty

Policies, especially in the European Union, encourage government and privately funded programs to engage in “energy efficiency first” strategies. Those policies lead to the moderation of energy demand and are long-term solutions that not only protect households from price fluctuations and energy poverty, but also allow people to reduce their environmental footprint and save money in the long term. Energy poverty usually occurs when a household is unable to secure a level and quality of domestic energy services—space cooling and heating, cooking, appliances, information technology etc.—sufficient for its social and material needs. In the Global North, energy poverty is generally attributed to internal and external factors such as low incomes, energy-inefficient homes and high energy prices, while in the Global South, the infrastructural lack of access to more technologically advanced energy carriers is the main culprit. Energy poverty in developing countries is gaining interest thanks to the seventh Sustainable Development Goal: Affordable and clean energy. Still, so far, in the European Union and in the rest of the world, little has been done to sew together the two concepts and include the most vulnerable part of the population in an approach that reconciles environmental and climate risks with social issues. In practice, energy poverty and efficiency agendas are rarely coordinated. Energy efficiency and a better pooling of the resources (known also as “sufficiency”) could lead to higher resiliency to the social and climate crisis.

Energy security of the European Union is one of the most important parameters that determine the present and the future on the world's geopolitical scene. EU countries are characterized by: insufficient fossil fuels from their own sources, continuous increase in consumption and strict environmental regulations (which limit the use of coal and oil). From all of the above, it follows that the long-term energy security of the European Union can be ensured by increase of gas supply capacity and diversification of sources of supply. The main objective of the paper is to analyze the situation and perspective of optimizing energy efficiency in the countries of the European Union through the application of resource of energy saving and new and innovative technologies of renewable resources.

The electricity production sector has a significant share of final energy consumption and has a huge potential to use more renewable energy sources. Over the last two decades, the European Union (EU) reform of electricity markets has had positive results, and market liberalization acts as a stimulus for energy efficiency, lower prices, and technological progress. Today’s EU policy for the development of electricity and the entire energy sector seeks to provide system modernization, stability, reinforcement of the single market, and implementation of climate change policy with an emphasis on the decarbonization of energy sources and the increase of energy efficiency. After all of the EU efforts to form an electricity sector in member states, it is necessary to assess the efficiency of the policy implemented and to identify the results achieved in shaping a sustainable electricity sector. The purpose of this article is to carry out a sustainability assessment of the electricity sector in the EU countries. A set of eight indicators designed to assess the sustainability of the electricity sector of different EU countries in 2017 has been drawn up. The assessment is made using the multi-criteria decision-making method (MCDM) Technique for Order Preference (TOPSIS). The assessment shows that the electricity market of Slovenia is the most sustainable, with Luxembourg in the second position in the EU.

Abstract One of the five far-reaching goals of the European Union is climate change and sustainable energy use. The first step in the implementation of this task is to reduce energy demand in buildings to a minimum by 2021, and in the case of public buildings by 2019. This article analyses the possibility of improving energy efficiency in public buildings, the relationship between particular indicators of the demand for usable energy (UE), final energy (FE) and primary energy (PE) in buildings and the impact of these indicators on the assessment of energy efficiency in public buildings, based on 5 variants of extensive thermal renovation of a school building. The analysis of the abovementioned variants confirms that the thermal renovation of merely the outer envelope of the building is insufficient and requires the use of additional energy sources, for example RES. Moreover, each indicator of energy demand in the building plays a key role in assessing the energy efficiency of the building. For this reason it is important to analyze each of them individually, as well as the dependencies between them.
