RES development trends that determine the sustainable development of the energy system of the future

To ensure reliable energy supply, it is necessary to solve a number of basic tasks: flexibility of energy systems, uninterrupted supply of energy, its availability to end consumers, resource efficiency and environmental safety. Sustainable development of the energy system involves changes along the entire energy conversion - chain from fuel and renewable generation and transmission of energy to optimizing its consumption. Many countries prioritize the development of renewable energy as the basis for low-carbon economic growth. Renewable energy sources contribute to the development of popular technologies not only in the field of sun and wind, but also in energy storage, hydrogen cycle, electric transport and e-mobility, energy efficiency of buildings, in the field of “smart” technologies, which ultimately affects improving the quality of life of people

Temperature and velocity conditions of air flow in vertical channel of hinged ventilated facade of a multistory building.

This article considers the influence of the building's tallness and the presence of mounting grooved lines on the parameters of heat transfer in the gap of a hinged ventilated facade. A numerical description of the processes occurring in a heat-gravitational flow is given. The average velocity and temperature of the heat-gravitational flow of a structure with open and sealed rusts are determined with unchanged geometric parameters of the gap. The dependence of the parameters influencing the thermomechanical characteristics of the enclosing structure is derived depending on the internal parameters of the system. Physical modeling of real multistory structures is performed by projecting actual parameters onto a reduced laboratory model (scaling)

The role of metallurgical clusters in the development of environmental engineering: new opportunities

This paper discusses the place and role of metallurgical clusters in the development of environmental engineering. The paper is based on research materials on the development of environmental engineering and the features of the functioning of metallurgical clusters. The paper studies the development of ferrous metallurgy, development trends, and developmental features of city-forming organizations of ferrous metallurgy. The main existing areas for development of metallurgical clusters and the relevance of environmental engineering development are shown

Balanced system of indicators for the assessment of innovative construction projects efficiency

The role of innovations in the construction industry is considered in the article. In the conditions of transition of national economy to the innovative type of development, the indicators that allow estimating the efficiency of innovative activity, where the key aspect is the comprehensive assessment, are important. Innovative projects are especially relevant for the construction industry, which is the key driver of the national economy development. Sustainable construction ensures the development of industries, where innovative projects can partly solve the problems of creating renewable energy sources. The authors offer to expand the list of indicators for the assessment of the innovative project efficiency not only from the financial and investment point of view, but also taking into account quantitative and quality, scientific, technological, operational, marketing indicators, which often are not considered. The assessment of the innovative projects efficiency has to be the central link in the innovation management; so the authors offer to improve the system of the balanced indicators. The balanced system of indicators (BSI) is developed. It is planned to extend and to introduce BSI not only at the level of the enterprises, but also for all the types of economic activity according to their technological effectiveness
