The problem of energy efficiency and rational use of energy resources in housing and utilities sector remains relevant over the past years. In this regard, the reduction of heating and hot water costs remains under continuous review of specialists all over the world. The article discusses the issues of using low potential thermal energy of domestic wastewater for hot water heating. Data on wastewater temperature in various locations are presented. The main designs of wastewater heat recovery units and the features of their application are considered. It is shown that the temperature parameters of residential building wastewaters differ significantly and depend not only on the climatic zone, but also on the regional features of water consumption. It is concluded that in process of wastewater heat recovery it is possible to reduce wastewater temperature at least by 5 ºС, and in hot season ‒ by 10-15 ºС. The analysis of literature data lead to the conclusion that wastewater heat recovery units are more promising and viable at building level as well as sewer or wastewater treatment plant level. For these cases, greater efficiency can be reached by using heat recovery facilities with a heat pumps.

In this paper we proposed a method for quantifying the total efficiency of programmable logic controllers from various manufacturers. The correct assessment makes it possible to select a programmable logic controller (PLC) as part of the implementation of the import substitution policy with a domestic product of devices from competing companies that have left the Russian market. The solution of the problem is carried out by the introduction of a linear rating scale for the selected characteristics of the PLC. Quantitative assessment of the qualitative characteristics of PLCs made it possible to obtain the value of the total efficiency for the PLCs considered in the work. Total efficiency is understood as a comprehensive assessment of the effectiveness of a programmable logic controller according to the selected characteristics. In this case, the characteristics may be of a different nature. We evaluated programmable logic controllers of four manufacturers: Siemens, Yokogawa, OWEN, ABAK. Seven characteristics of the PLC were selected for evaluation: mean time between failures, number of interfaces and plug-ins, power consumption, temperature range, number of protocols used, and response speed. The possibility of implementing the import substitution policy is considered. The assessment of the total efficiency confirmed the competitiveness of domestic PLCs in relation to foreign ones. The development of the presented evaluation method will make it possible to analyze the effectiveness of complex, large control systems made up of different types of equipment. The presented method can be used over time to obtain up-to-date information about the total efficiency.

The paper presents the results of research on the development of the composition of the raw mixture for the production of facing composite material for construction purposes. The composition of the raw material mixture included a brick fight as a filler, waste products from non-plasticized polyvinyl chloride as a binder and methylene chloride for dissolving polymer waste. This composition allows mixing and pressing without heating, which eliminates the possibility of destruction of the polymer component. After pressing, heat treatment is carried out at the solvent evaporation temperature. The paper shows the dependences of the main physical and mechanical characteristics of the resulting material on the degree of filling. The maximum amount of filler has been set, which allows to obtain the material without a lack of binder. With a lack of binder, a decrease in strength and an excess of the proportion of open pores over closed ones were observed. According to the results of the experiments, the polymer : solvent ratio and the degree of filling were selected, allowing to obtain a material with the maximum value of strength characteristics. Practical application of the developed composition of the raw mixture will allow complex utilization of low-demand and large-tonnage polymer and brick waste to obtain composite material for cladding buildings and structures.

The results of studies of two-layer reinforced concrete beams with a layer of various thicknesses of high-modulus concrete of the frame structure in the compressed zone and traditional heavy concrete in the rest of the section are presented. The stress-strain state of normal cross sections along the height of the beam was estimated by the values of relative deformations at the level of stretched and compressed reinforcement using the hypothesis of flat sections and actual compression and calculated tensile deformation diagrams of concrete. The influence of the thickness of a layer of high-modulus concrete on the nature of the stress-strain state between the layers is shown. The possibility of destruction of the beam on the concrete of the compressed zone was revealed due to the abrupt decrease in the actual height of the compressed zone due to the "shooting" of a layer of high-modulus concrete with its thickness less than 0.1 h0. The dependence of the relative actual thickness of the compressed concrete, i.e. the distance from the edge fiber of the compressed concrete to the neutral axis, in the studied beams on the magnitude of the bending moment is obtained. It is established that for single-layer beams, with a difference in the elastic modulus of concrete up to 20%, the dependences of the relative actual thickness of the compressed concrete layer on the bending moment are almost identical. In the studied beams, the limiting state of which is caused by the fluidity of the reinforcement, the thickness of the compressed concrete layer was 0.37 ...0.4 with a relative moment value of 0.5, and 0.33 ...0.36 with a maximum bending moment value.

Complex flows (CFC, CFA, СFP) are calculated using the critical method. A comparative analysis of the methods of complex flows was made, which showed that the CFC and CFP have the shortest duration of the overhaul of the facades of three objects, which is 131 days. Based on a comparison of the options for calculating complex flows by different methods, we can conclude that the CFP method is the most suitable, because the duration of the overhaul is the shortest. CFP is the traditional and most optimal method that ensures the minimum duration of the whole complex of works and is widely used at the present time.
