“…In the workshops of the enterprise, emissions of carbon monoxide are observed, sulfur dioxide is emitted -at sinter plants, in the blast furnace shop and in the mixing department of steel-making shops, although the concentration of sulfur dioxide in the air does not exceed the maximum permissible (10 mg/m 3 ), gas emissions and dust are also observed, predominantly in shops and in the areas of charge preparation (contains up to 15-20 % and more free and amorphous silicon dioxide, over 50 % of iron oxides and other impurities); noise (from 90 and over 100 dB) [22][23][24].…”

In recent years, environmental-oriented concepts of sustainable urban development have been actively developing, in particular, in the spheres of energy efficiency and resource conservation in the context of the theory of thrift, smart and environmentally-oriented creation. Four scientific concepts can be distinguished from a set of scientific theories and methodological approaches: industrial metabolism; control «on the pipe»; social and ecological metabolism, thrifty production. In particular, the concept of «lean manufacturing» has shown its effectiveness in practice in many countries in various industries. This concept is environmentally friendly, has a high potential for implementation, but is not sufficiently appreciated by domestic enterprises. Despite its widespread implementation and development, the lack of its implementation at domestic industrial enterprises is explained by the lack of adapted methods and tools for resource conservation management based on this concept. It explains the relevance of the study, which proposes a theoretical and methodological substantiation of the program for a phased transition to «lean manufacturing», which ensures an increase in the efficiency of enterprises in modern conditions, which will increase the sustainability of cities ultimately.

Production processes sometimes are accompanied by the release of hazardous substances, the composition and volume of which is determined by the production technology. When designing ventilation systems for paint departments, special attention is paid to safety concerns, since all paint coatings are corrosive and flammable substances. Besides, solvent vapors are explosive. For local ventilation of painting chambers, it is rational to use safe exhaust systems with an ejector, which works sturdily, regardless of the release of flammable and explosive impurities. The ejector is simple in design and can operate in a wide range of changes in the parameters of the state of airflow. The model of the ejection unit is synthesized using the universal modeling package ChemCad, which contains a highly developed database of airflow parameters, which allows for solving various applied problems. Numerical modeling was carried out using the software package - FLUENT. In work, a calculation was carried out and a low-pressure ejector was designed for a typical painting booth. The calculation results are presented in the form of graphs and tables of pressures, velocities, flow rates in characteristic sections, pressure losses in the sections of the ejector installation.The ejection coefficient was also calculated.

“…The adoption of federal and regional regulations in the field of energy conservation indicates the existence of problems in the thermal power sector. The objectives of improving energy efficiency and energy saving of such critical building engineering systems as heat supply and ventilation are considered by many researchers [1][2][3][4][5][6].…”

The efficiency of works on replacement of steel pipelines of hot water supply of Kazan with pipes from polymer materials was considered. Due to the high corrosive activity of water, the service life of hot water pipelines does not exceed 8-10 years. To improve the reliability and quality of the supply of hot water to consumers, the possibility of modernizing hot water supply networks using pipelines made of polymer materials is being considered. The problem of physical wear of heat supply networks is disclosed; analysis of polymer pipelines use for energy saving purposes is carried out. Thermal energy savings are calculated after the modernization of heating networks. The costs, savings and payback period of the energy-saving measures are determined.
