This article deals with the problem of energy saving and energy efficiency improvement in the construction sector, which consumes a significant share of the country's energy resources. Issues of rational use of energy resources with aspects of energy saving, energy efficiency and, accordingly, environmental problems are becoming more and more urgent, and their solution has become a strategic task for Kazakhstan. With the aim of catalyzing the energy-saving measures undertaken in Kazakhstan, a number of laws, subsidiary laws and programs related to the issues of rational use of energy resources and energy efficiency improvement have been adopted. Targeted activities are planned to eliminate existing political, legislative, technical and information thresholds in order to solve this problem. The regulatory and technical framework premised on the advanced achievements of construction science is being developed. The current legal and regulatory framework and technological infrastructure, as well as the existing practice, are being analyzed. In this context, actions are being taken to introduce new mandatory requirements for thermal indexes in building regulations and other changes in the energy efficiency of buildings; systems for assessing and labelling energy efficiency and their implementation are being developed. Voluntary standards for "green buildings" and incentive mechanisms for their application are also being developed, procedures for State architectural and construction supervision of compliance with building standards and other requirements for the construction of buildings are being improved, greenhouse gas accounting systems are being developed and implemented based on data from the energy consumption accounting system and energy passports.

In order to improve energy efficiency by increasing heat dissipation performance of bus-bar which distributes the current in high-power switchboard, the heat dissipation effects of the shape modification and surface treatment of Cu bus-bar were studied. The surface temperatures of the conventional plate-type bus-bar, and the improved tunnel-type bus-bar were compared by using electromagnetic and thermal analyses. The optimum thickness of tunnel-type bus-bar and the spacing and array among three bus-bars were calculated; and the surface temperature of tunnel-type bus-bar showed 7.9 °C lower than that of plate-type bus-bar in a 3-phase array condition. In addition, the surface and internal temperatures of the uncoated, CNT (Carbon nanotube)-coated, and BN (Boron nitride)-coated Cu bus-bars were measured with thermal imaging camera and the experiment using a hot plate. It was confirmed that the difference in the internal temperature between uncoated and BN-coated Cu was 19.4 °C. The application of the bus-bar improved from this study might contribute to the increase in power energy efficiency.

In addition, the author explains the editorial board’s choice of the main topic of the next issue of the legal journal of Volgograd State University “LegalConcept = Legal paradigm” under the title “The right to protect human health and an environmentally friendly business environment”. The objective need for the technology development of the intensive involvement of the potential of Russian environmental entrepreneurship in the industrial revolution processes is substantiated. The most important tasks are identified, which are addressed by the developments in the legal regulation of the digitalization processes of environmental entrepreneurship in Russia. The author lists a set of measures that, in the author’s opinion, are of primary importance for ensuring these processes. It is noted that the topic proposed for development is closely related to the formation of scientific and technological foundations that ensure the economic growth and social development of the Russian Federation. The state of scientific and technological progress achieved by modern society is manifested by the widespread use of digital technologies in various areas of production, business management, the provision of services in medicine, the banking sector, and the social sphere. It is proved that comfortable life, the security of the processes through qualitatively new regulatory approaches, the state security, including cybersecurity, overcoming the adverse effects due to natural disasters, as well as the introduction of biotechnology, entailing the appearance of unknown infectious diseases and viruses, preventing man-made disasters – these and many other goals and objectives can’t be achieved now or get a solution without the use of digital information technologies. It is also impossible to ignore the studies of the society and nature interaction, the cross-sectoral impact of modern technology in the field of renewable energy, the turnover of energy resources and energy efficiency improvement on the environment, the life and health of citizens, the public and state institutions designed to participate in the protection of the environment which corresponds to the solution of the specific objectives set in the Strategy for Scientific and Technological Development of the Russian Federation.

One of the strategic objectives of the European Union is a reduction in greenhouse gas emissions and improvement of energy efficiency by at least 32.5% in different areas of the economy by 2030. However, little is known about the impact of payment in retail on energy consumption. The purpose of this paper is to assess the chain of losses of time and energy, and therefore financial losses, that occur due to the imperfection of payment infrastructure and instruments using data of cashiers’ working time. The research is based on a regression analysis method, where the energy cost per payment transaction is considered in this study as a function of the number of customers per hour and the energy cost. The results of the panel models highlight that the number of customers per hour has a negative impact on the cost of energy per payment transaction. Furthermore, modern means and methods of payment, including cryptocurrencies, do not solve the problem of the excessive time that it takes to service payments, which entails a waste of energy and money. The empirical results give valuable insights into how to best organise payment in retail to achieve lower energy costs and improve energy efficiency in payment infrastructure.

Abstract Terrestrial mobile robotics are increasingly important to a range of missions including planetary exploration, search and rescue, logistics, and national security. Many of these missions require the robot to operate on a broad variety of terrain. Wheels are ideal for energy efficiency but can suffer catastrophic failure when presented with obstacles or complex ground. Legs can help navigate obstacles but at the cost of energy efficiency. Physical adaptation can enable a robot to benefit from both modes of locomotion. This paper describes a new approach to physical adaptation through manipulation. Specifically, this paper examines how manipulators can be used to change the vehicle's mode of locomotion and improve energy efficiency and versatility. This paper presents “swappable propulsors”, which can be easily attached/detached to adapt the vehicle through the use of permanent magnets. A new robot system that uses its manipulator to discretely switch between wheeled and legged locomotion is created. The experimental results demonstrate how this approach provides a unique combination of energy efficiency and versatility. This work describes the design of swappable propulsors, analyzes how to manipulate them, and describes how they can be used to improve performance. This work extends on prior work with additional analysis, an improved robot prototype, and new experimental results.

The article substantiates the necessity and relevance of the introduction of progressive energy efficiency systems at industrial enterprises. It is shown that in Ukraine in 2020 only 43.1% of energy resources are used efficiently, according to the data of the energy efficiency rating. In 2019, this figure was higher - 54%. The analysis of the use of energy resources in industry, services, agriculture and the housing sector in Ukraine, as well as in the countries of the European Union. The issues of organizing energy efficiency benchmarking for industrial enterprises of Ukraine are considered. The main attention is paid to an integrated approach, which consists in creating a regulatory framework and organizing information support during benchmarking. The experience of the EU countries in solving the problem of technical regulation of energy efficiency benchmarking and the possibility of its use in international entrepreneurship is considered. Only the main stages of energy saving benchmarking are considered in detail, which include: selection of a benchmark, comparison and assessment, positioning of the research object and determination of leaders and outsiders, grouping benchmarking partners by energy efficiency level, identification of the gap, identification of the causes of inefficient energy consumption, determination of the scale and nature of the problem. The introduction of an energy efficiency benchmarking system on a regular basis as a control and planning subsystem as part of an energy management system will make it possible to track changes in the energy efficiency indicators of the production system and its structural objects, the level of energy efficiency over time, negative trends and causes of their occurrence, to assess the effectiveness of adaptation of the best principles of efficient energy consumption in own conditions and the effectiveness of the implementation of energy-saving measures, which will contribute to the continuous improvement of the production system and its facilities.

Improved energy efficiency in supply chains can reduce both environmental impact and lifecycle costs, and thus becomes a competitive advantage in the work towards a sustainable global economy. Viewing the supply chain as a system provides the holistic perspective needed to avoid sub-optimal energy use. This article studies measures relating to technology and management that can increase energy efficiency in the supply chains of five aluminium products made in Sweden. Additionally, energy efficiency potentials related to the flows of material, energy, and knowledge between the actors in the supply chains are studied. Empirical data was collected using focus group interviews and one focus group per product was completed. The results show that there are several areas for potential energy efficiency improvement; for example, product design, communication and collaboration, transportation, and reduced material waste. Demands from other actors that can have direct or indirect effects on energy use in the supply chains were identified. Despite the fact that companies can save money through improved energy efficiency, demands from customers and the authorities would provide the additional incentives needed for companies to work harder to improve energy efficiency.

AbstractImproving energy efficiency in industries is imperative for sustainable transitions. This article explores the logic behind calculating energy savings from energy efficiency improvements. Based on a qualitative study of industry-research projects and policies to improve energy efficiency in Norway, the article presents different ways energy savings are estimated when assessing the viability of novel technologies. Here, energy savings are calculated as the difference in energy consumption between a proposed technology (use-case) and an alternative scenario (base-case). We discuss the heterogeneity of the chosen cases of comparison, as they are associated with a wide variety of uncertainty, contextual preconditions, estimates, and projections. Further, we trace the calculations of energy savings of one of these projects as they move from the context of research and technology assessment to official reporting. We show how the circumstances where these numbers are produced become black-boxed as the calculations are transformed and aggregated into a policy program-specific measurement “energy results” in Norway. Our findings show that the project and policy objectives and measurements point in somewhat different directions. Through this, we unpack the logic inscribed in energy savings calculations and the way these are applied to reach multiple goals.
