  • Experimental assessment of fine dust pollution from warehouses during the placement of building materials

    In this paper, an experimental assessment of dust emissions from warehouses of building materials from the point of view of their impact on the air environment is carried out. The technological operation of placement, in which dust is formed in a closed warehouse, is considered. It was revealed that in the process of placing building materials, the source of dust emission is aeration lights and windows. The dispersed composition of emissions entering the environment from unorganized sources (windows, aeration lamps) was experimentally determined by the height of the room.

  • Investigation of the dust factor in the residential premises of a multi-storey student dormitory

    This article is devoted to the study of the dust factor in the residential premises of a student dormitory during repair work, including the assessment of the regularities of the distribution of solid suspended particles by equivalent diameters (PM0.5, PM1, PM2.5, PM5 and PM10) and the determination of their concentrations.

  • The method of calculating the S-factor for an apartment building

    Evaluation of the effectiveness of ""green"" buildings is usually carried out by a third party using a rating system. The rating system STO NOSTROY 2.35.4–2011 assesses habitat sustainability according to 46 criteria, which are grouped into 10 categories, presented in Table 1. STO NOSTROY 2.35.4–2011. The article presents the methodology developed on the basis of the above-mentioned rating system, as well as the foreign LEED system, and the S-factor for the designed 16-storey residential building is calculated. The calculation for clarity is presented in the form of a diagram. Since the design we strive to get as close as possible to the highest grade of assessment, the most attention is paid to such concepts as energy saving and energy efficiency. Calculation of economic efficiency is possible on the basis of the resource-technological model by calculating the volume of waste during the overhaul and demolition of the designed building. This is a necessary task, since the construction of environmentally-friendly, sustainable buildings requires full consideration of the life cycle of the building, and accounting for the entire life cycle necessitates integrated design. The time spent at an early stage on the complex design of the building, taking into account the concept of sustainable development, is rather quickly compensated with the start of building operation, since it is known that the largest share of costs falls on the operational period of the building. So, as a result of calculating the S-factor, the building is assigned a certain grade of assessment. Raising the grade of an assessment of a building being erected will lead to an increase in its investment attractiveness. That is why it is important to perform a similar calculation at the design stage of the life cycle of the construction object, since in this case we have the opportunity to increase the value of the S-factor to the required.

  • The evaluations of the complex analysis’ results of dispersed dust particles using hydrodynamic criteria for decreasing dust leakage out from decreasing dust systems of aspiration’ emissions in the production of building industry

    The article is devoted to the issue of improving the environmental safety of the construction industry by improving the systems of decreasing dust emissions by aspiration systems using a comprehensive dispersive analysis. There was proposed to develop a promising approach using the criteria of hydrodynamic similarity in the output functions of the complex analysis of variance to increase the efficiency of aspiration decreasing dust systems in this article. The article focuses on the environmental problems of building construction industry. The volume and different kinds of mixtures of bulk building materials and cements to produce various types of concrete construction units and materials are in stable demand every year. It means that average amount of dust particles substances in emissions at the manufacturing production of building materials every year too. The results of studies show that a significant content of fine particles, for example, 10 microns or less is concern in dust emissions systems of aspiration at the building construction enterprises. One of ways to increase the environmental safety is reduction of dust emissions to design dust capturing devices that have low values of slippage out from aspirations’ decreasing dust systems. It was achieved by special complex integrated analysis’ method of variance dust that applies hydrodynamic sedimentation of particles. It is the way to obtain distribution of dimensionless numerical complexes — the hydrodynamic similarity criteria for the dust studied samples. There presented results of experiment that gave more reliable approach to get evaluations of the complex analysis of particles sedimentation velocity’s distributions.

  • Investigation of the surface properties of fibrous materials taking into account the climatic conditions of the environmental spaces of construction objects

    The article presents the results of studies of the surface characteristics of textile materials used for personal protective equipment and in construction projects, taking into account the climatic conditions of their operation. The features of their optical and color properties in the open industrial area in the cold period, which form the elements of General industrial safety, are revealed. The influence of low temperature and humidity on the structure and surface properties of materials of the different fibrous composition is experimentally established. This leads to the correction of optical parameters of various objects on construction and industrial sites, determining the conditions of sufficient or limited visibility. The results are adapted to solving the problems of designing environmental spaces of construction projects and the development of innovations in textile materials science and means of individual safety in the industry.

  • Problems of formation of innovative economy in Russia, taking into account environmental factors (for example, recreational region)

    The article shows the fundamental importance of integrating environmental considerations into economic development of modern countries. Identified the problem of forming an innovative economy based on environmental safety and efficiency of use of natural resources. We prove the thesis of the need to integrate environmental considerations into the system of economic relations in the direction of the explication of the reasons for the ineffectiveness of the current ecological economic mechanism of nature. Identifies the main problem areas for example recreational nature resort region of Russia - the Caucasian Mineral Waters. Suggests ways to improve the organizational and economic mechanism of nature on the basis of a systematic accounting of natural resource rents and stimulating environmental management.
