This paper analyzes structural indicators of economic efficiency and energy intensity consumption as determinants of sustainable economic development for the selected 33 European countries. The correlation, regression and multivariate factor analyses are applied to test the associations between the selected structural variables of energy intensity consumption, economic efficiency, and the main driving forces behind these developments. Economic efficiency is positively associated with expenditures on research and development (R&D) and a greater technological intensity of exports, while at the same time the economic efficiency of R&D expenditures and technological intensity of exports reduce the energy intensity consumption of the economy. The results suggest that management strategies and policies directed towards R&D expenditures, human capital investments, and technologically intensive export oriented products are improving economic efficiency performance and contributing to energy saving sustainable economic development. The technological intensity of products reduces energy consumption, which is related to restructuring of energy intensive industries into more advanced and energy saving ones with higher value added per unit of product, but with lower energy consumption per unit of product. Santrauka Autoriai analizuoja struktūrinius ekonominio efektyvumo ir energijos vartojimo intensyvumo, kaip vienų iš pagrindinių subalansuotos plėtros kintamųjų, rodiklius. Tirti buvo pasirinktos 33 Europos valstybės. Autoriai, siekdami pagrįsti iškeltus teiginius, naudojo koreliacinę, regresinę analizę bei daugiakriterinius metodus galimoms ekonominio efektyvumo bei energijos vartojimo laipsnio (ir kitų, ne mažiau svarbių elementų) variacijoms nustatyti.

Target. To analyze the features of energy consumption of the building of the educational building No. 17 of the National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute" in the conditions of quarantine restrictions in the implementation of energy-saving heating schemes.Methodology. Dynamic energetic modeling of a university academic building created in the DesignBuilder software environment under normal and quarantine modes.Results. Recommendations for the implementation of energy-saving modes of heating the building of the academic building of the university during the period of distance learning when introducing quarantine restrictions in Ukraine.Scientific novelty. An integrated approach has been developed to an in-depth analysis of energy consumption under conditions of partial use of the premises of educational buildings during the quarantine period. It is substantiated that the use of premises with partial operation of the building requires additional unit costs for heating needs.Practical significance. Simulation dynamic modeling of the building's energy consumption for heating for various modes of operation and employment / use of premises of educational buildings during the quarantine period in Ukraine, the results of the study will allow to obtain a set of energy characteristics of the building as a whole and its individual rooms / zones for hourly changes in internal operating conditions and external climatic conditions. The use of the proposed scheme of operation of the heating system of the building of the educational building allows to reduce energy consumption during the heating period by 8,5% compared to energy consumption during normal operation, which is economically feasible in conditions of partial occupancy of the building during quarantine restrictions (during lockdown) and an unpredictable macroeconomic situation on the energy market, causing a trend towards an increase in prices for basic energy resources.

Energy-efficient retrofitting of historic housing stock requires methodical approach, in-depth analysis and case-specific regulatory system, yet only limited efforts have been realized. In large scale rehabilitation projects, it is essential to develop a retrofit strategy on how to decide energy-efficient solutions for buildings providing the most energy saving in a short time. This paper presents a pilot study conducted at a neighborhood scale, consisting of 22 pre-, early-republican and contemporary residential buildings in a historic urban fabric in the Mediterranean climate. This study aims to develop an integrated approach to describe case-specific solutions for larger scale historic urban fabric. It covers the building performance simulation (BPS) model and numerical analysis to determine the most related design parameters affecting annual energy consumption. All the case buildings were classified into three main groups to propose appropriate retrofit solutions in different impact categories. Retrofit solutions were gathered into two retrofit packages, Package 1 and 2, and separately, three individual operational solutions were determined, considering a five-levelled assessment criteria of EN 16883:2017 Standard. Energy classes of case buildings were calculated based on National Building Energy Regulations. Changes in building classes were evaluated considering pre- and post-retrofit status of the buildings. For the integrated approach, the most related design parameters on annual energy consumption were specified through Pearson correlation analysis. The approach indicated that three buildings, representing each building group, can initially be retrofitted. For all buildings, while maximum energy saving was provided by Package 2 with 48.57%, minimum energy saving was obtained from Package 1 with 19.8%.

As the current network is designed for peak loads, it results in insufficient resource utilization and energy waste. Virtualized technology makes it possible that intelligent energy perception network could be deployed and resource sharing could become an effective energy saving technology. How to make more small cells into sleeping state for energy saving in ultradense small cell system has become a research hot spot. Based on the mapping feature of virtualized network, a new wireless resource mapping algorithm for saving energy in ultradense small cells has been put forward when wireless resource amount is satisfied in every small cell. First of all, the method divides the virtual cells. Again through the alternate updating between small cell mapping and wireless resource allocation, least amount of small cells is used and other small cells turn into sleeping state on the premise of guaranteeing users’ QoS. Next, the energy consumption of the wireless access system, wireless resource utilization, and the convergence of the proposed algorithm are analyzed in theory. Finally, the simulation results demonstrate that the algorithm can effectively reduce the system energy consumption and required wireless resource amount under the condition of satisfying users’ QoS.

One of the most important strategic objectives is to create a sustainable model for the development of the Kazakhstan economy, which is closely linked to the solution of energy saving and energy efficiency in the construction industry. The main principles of the energy efficiency strategy include integrated approach (efficient use of energy at all stages of the facility's life cycle for all types of energy resources, with legal support and organizational and technical control by the state) and systematic approach (the study of the process using general rather than partial approach). The article analyzes key problems and barriers that prevent the successful implementation of energy saving and energy efficiency policies. A significant role in the rational use of energy resources belongs to the regulatory framework. It was revealed that currently existing regulatory and technical documents in the country, unlike similar documents in EU countries, have a number of inaccuracies and disadvantages that do not allow for a full accounting of energy consumption. At present, there is practically no effective methodology for determining the energy efficiency of residential buildings and structures in Kazakhstan. In this regard, a methodology for determining the energy efficiency of buildings and structures, harmonized with EU requirements (taking into account energy consumption for heating, ventilation, high-temperature water supply, cooling and lighting) is currently being developed. The energy efficiency improvement of new, renovated and operated buildings will make it possible to reduce greenhouse gas emissions, thus contributing to solving both global environmental problems and energy and environmental security in the Republic of Kazakhstan.

The study of the behavioral aspects of households in the field of energy conservation is one of the activities of the global energy policy. From this perspective, the topic of the article is relevant. The purpose of the study is to consider the theoretical and methodological basis for studying the transformation of energy-saving behavior of a household in the context of the introduction of digital and nature-like technologies. The authors, based on the use of provisions (neoclassicism, institutionalism and Keynesianism), investigated the essence and manifestations of energy-saving behavior of a household in such conditions. For a deeper study, an analysis of organizational forms, institutional infrastructure, technical and technological relations arising in the process of energy consumption is proposed. Based on this analysis, a number of results have been obtained. The very concept of “energy” is used in a broad sense, as consisting of many of its types and used in consumption by households. The overall result of the study is the provision that the energy-saving behavior of households should be investigated in a comprehensive manner with the integration of various theoretical concepts. In the absence of such an integrated approach, the energy-saving process at the household level will be divided into different actions, including contradictory or even opposite ones, which will affect the effectiveness of the government measures taken.
