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.

The article is devoted to the approach to the development and design of effective dust collectors for the aspiration systems of the construction industry. It was proposed and implemented the study of the particle shape factors that determine the hydrodynamic features of gas flow around dust particles, for example, in the aspiration schemes, which are most spread and applied in the construction industry using the results of complex analysis of variance it this article. It was presented results of implementation hydrodynamic criteria in the output function of the analysis. The values’ meanings of the particle shape factors of the dusts’ particles were gained and obtained at the final stage of experiment. It was obtained regressions for particle shape factors as functions of hydrodynamic criteria. It was proposed dependences to clarify the particle sedimentation-growth velocities taking into account the influence of the particle shape factors of the studied dust samples. It was allowed possibility to assess and obtain ranges of changes in the values’ meanings of particle shape factors. It was obtained more reliable results for determining the sedimentation values’ velocities of dust particle as a determining result of complex analysis of variance of particles also. The research results allow the development and design of dust collecting devices for cleaning emissions in dust removal systems of the aspiration schemes of the construction industry. These dust kinds of collector provides a significant reduction in dust leakage out from dust removal systems of the aspiration. This way become one of the highly effective prevents polluting ways that allows to improve environmental safety of the construction industry.

Describes three стратегиb housing reconstruction of the first mass series: the radical, complex, a conservative. Implementation of the existing strategies is impossible without the development of additional organizational and technological measures (OTM). When developing OTM should be based on the division of the whole complex of works on reconstruction of the separate stages and associated volumes, which can be performed independently and at different times. In a basis of an element-centric approach to the reconstruction should be based on the principle of economic feasibility and interest of all participants in the process of reconstruction. OTM in поэлементном approach to the reconstruction of forming a system of relations, rights, duties and mutual guarantees of the participants, secured by means of linking the investment cycle for reconstruction into a single organizational-technological building system (ОТСС)

The concept of creation of energy-efficient areas in cities in the reconstruction and secondary residential blocks and micro-districts consists in the fact that, in practice, to prove the real possibilities to reduce energy consumption per unit area of housing in the housing and communal sphere in two and more times due to the implementation of the already well-known energy-saving technical tools and solutions, rational use of their possible combinations of the specific nature-climatic and city planning conditions. The creation of energy efficient zones requires a comprehensive consideration of issues and the systematic development of power supply at all stages of production, transportation and consumption of energy from the modernization of the objects of the engineering infrastructure

Is considered the superstructure of attic floors, as the most simple and effective техническиое decision in the reconstruction of buildings of massive series . Considered two variants of the device attics for residential buildings of the first mass series. The superstructure of mansard floors this is a very difficult technical, economic and social problem, and requires a scientific substantiation and consideration of a complex of organizational and technological issues of reconstruction, a detailed examination of each building, thorough comparative analysis of alternative variants of engineering solutions. In each case it is necessary to take into account the totality of the various factors and first of all the social aspects of reconstruction

Implementation of civilizational model of society development lies primarily in the fact that an essential quantitative increase in the energy budget of each person and the state should be ensured while reducing unit costs of energy, among which the most significant:
• lower energy costs per unit of gross domestic product (GDP);
• economical use of heat for the industrial and heating. In the conditions of transition of the country's economy to market relations reconstruction of the existing large-panel, крупноблочных, brick and other constructions of 50 - 70's, is today a strategic direction in solving the construction of the problems, which allows you to not only extend the life of the buildings, but also significantly improve the quality of life and comfort of living of the people, convert the architectural appearance of buildings and streets. At the same time you will be able to increase the total area of residential buildings, establish new types of comfortable rooms of various purposes.
