Waste management in the city`s master-plan development We list the main results of the research work on the subject of production of a draft master plan for the development of the city district - the Yekaterinburg city municipality for the period up to year 2035 concerning the engineering infrastructure.   The disposal of unsorted waste at landfills leads to undesirable environmental consequences (pollution of soil and groundwater, and CO¬2, CH4, H2S emissions into the atmosphere), and constantly requires more and more space. Currently, since there is a tendency to increase the amount of generated waste by 3-5% annually, the area of landfill sites is constantly increasing, taking up more and more land plots, which, without costly treatment, become no longer suitable for further economic use. Each year, about 5 million tons of MSW are generated in the territory of the municipal district "Yekaterinburg city". No more than 5% of waste is recycled. The rest is deposited to landfills for municipal solid waste. The analysis of the capacity of the landfills currently in operation demonstrated that the amount of waste planned for deposition and disposal exceeds the landfill capacity twofold, which leads to a significant load on the landfill and violations of the technology of safe waste disposal.  Considering the abovementioned, a planned scheme was developed for municipal solid waste streams of the municipal district “Yekaterinburg city”. Municipal solid waste generated in the territory of the municipal district “Yekaterinburg city” will be delivered to the locations of waste accumulation (container sites). We have assumed separate garbage collection on the territory of the municipal district. Waste to be recycled is placed in special containers, and then it is supposed to be forwarded to waste sorting complexes. Non-recyclable waste is planned to be placed at two inter-municipal waste management centers (IMWMC): about 50% of it – at the IMWMC in the urban district Verkhnyaya Pyshma (the Severny polygon), and the remaining 50% - at the IMWMC in the urban district Beloyarsky. The waste suitable for recycling will be picked out in waste sorting complexes, and then will be sent to the relevant industrial enterprises. Among the main types of waste that are subject to recycling are: ferrous and non-ferrous metals for remelting, cellulose and waste paper for paper production, polymers for production of building materials (for example, PVC window frames), and glass shards for production of recycled glass containers . 10.18720/CUBS.76.3 69 Architecture civil and structural engineering waste management and disposal master plan engineer infrastructure municipal solid-waste landfill https://unistroy.spbstu.ru/article/2019.76.1/ 76_1.pdf

Determination of the cost of insulation on their thermophysical characteristics The use of energy-efficient materials (heat insulators) in the construction and renovation of buildings and structures is a key factor affecting the heat balance of the building (minimizing heat loss through the building enclosing structures). It is known that reducing the cost of heating (the consumption of heat or thermal energy) is an important technical and energy problem, especially for the conditions of the northern regions. The main way to save energy is to insulate enclosing structures, in particular, walls. However, a compromise between reducing the heat loss of a building and the economic efficiency of energy-saving measures is important. This article describes the method of justifying the dependence of the cost of heaters on their technical characteristics, based on a statistical analysis of price and thermal characteristics, used later in the development of optimization models for the selection and use of heaters. 10.18720/CUBS.76.2 69 energy efficiency enclosing structures insulation heat conduction coefficient mathematical model cost coefficient of determination https://unistroy.spbstu.ru/article/2019.76.2/ 76_2.pdf

The technical and economic basis of facade systems The problem of energy saving and increase of energy efficiency of buildings by improvement of constructive solutions of facade systems is relevant. The complex assessment of indicators of various types of façade systems is absent at present. The object of research is the facade of the apartment house projected as a part of a housing estate for a cold Russian climate (HDD = 7649 K*days/year). Two types of modern facade systems, such as the facade thermal insulation composite system with external mortar layers and the ventilated facade system are considered. The comparative analysis of thermal performance, economic and operational characteristics of these facade systems is carried out in this article. Following the results of the technical and economic analysis of these facade systems the conclusion is drawn that facade thermal insulation composite systems with external mortar layers are more reliable and economically reasonable systems. It opens great opportunities of their further studying for the purpose of their effective application in modern construction. 10.18720/CUBS.76.4 69 facade system enclosing structure thermal protection resistance to heat transfer economic analysis durability fire https://unistroy.spbstu.ru/article/2019.76.3/ 76_3.pdf
