The system of geotechnical arrays is a joint structure of a horizontal geotechnical array (modified soil layer) and a continuous enclosing array located along its perimeter. The purpose of the system is to limit the flow of groundwater into the underground part of the building and to ensure the normative limits of vertical movements of the main building and its surrounding development. One of the most important tasks of ensuring the operational reliability of such a system is the prediction of the stress-strain state of all its elements on the impact of a complex of natural and technogenic loads. The article presents the experience of assessing the stress-strain state of such a system, which is formed during the arrangement of the underground space of the Esplanade multifunctional complex in Perm.

The transformation of weak soil foundations during the construction of buildings and structures in the permafrost zone can be considered as a constructive measure that makes it possible to ensure their long-term operational suitability in climate warming. Innovative for permafrost is the stabilization of soil using jet grouting technology, as a result of which a new material is formed – soil cement. At the moment, the thermal-physical properties of the soil cement necessary for predicting the thermal stress-strain state of the transformed bases from permafrost soils under climate warming conditions have not been studied. The normative documents do not contain the thermo-physical characteristics of soil cement, taking into account the soils in its composition and the technology of the arrangement of soil cement elements. As a result of laboratory tests conducted at the NIISF RAACS, the density, humidity, water absorption, and thermal conductivity of the cement soil samples were determined. The coefficient of thermal conductivity λ was measured by the IVTP-12 device, the principle of operation of which is based on the dielcometric method of measuring the properties of materials. For the first time, the characteristics of the thermal conductivity of soil cement in the thawed (λ_th) and frozen (λ_f) state were determined at different water content values W and density ρ of the samples. For the soil cement obtained in clay and sandy soils, graphs were constructed and dependences of thermal conductivity of soil cement on its density were established.

Wood-based materials are widely used in modern construction technologies as part of the concept of biopositive construction related to the design and construction of buildings, taking into account the impact on human health and well-being, as well as on the ecosystem as a whole. The main disadvantage of bio-positive wood materials, like any organic materials, is their high flammability. In this regard, improving the thermal stability of wood materials and, as a consequence, reducing their combustibility is a very urgent task. The purpose of the research described in the article was to study the possibility of increasing the thermal stability of wood materials and, as a consequence, reducing their combustibility. As a result of conducted active experiment and statistical processing of its results, the optimum flow rate of flame retardant and substrate moisture content were established. To determine the kinetic parameters of the thermal decomposition process of cellulose materials of different chemical composition (integral method), a Du Pont-9900 automated modular thermal analyzer system was used. As a result of studies it was found that boron-nitrogen wood surface modifiers stabilize lignocarbohydrate complex of wood at the stage of flame burning (the second temperature interval) and significantly reduce the value of weight loss of the substrate at this stage.

The significance of the transmission of universal experience is extremely important, as this process implies not only the transfer of accumulated experience from the previous generation, but also the optimisation of those socially approved approaches to the organisation of human life activity in the conditions of society, which are behind the further development and formation of humanity. Nevertheless, various social, public and cultural processes differently affect the development of means of transmitting universal experience, thus not always becoming a condition for conflict-free further development. Culture is a set of sign-symbolic systems that accumulate the experience of existence in the form of ways of perception, thinking, cognition, experience and action, knowledge, values, methods and criteria for evaluation, standards, goals and meanings. Architectural spaces, being one of the most important forms of existence of culture, are also a way of generating, preserving and transferring the experience of a person and a community. The focus of this study is on the ways of broadcasting and retransmitting human experience in the urban space of St. Petersburg. St. Petersburg, thanks to various semiotic systems of different eras, is a translator of many verbal and non-verbal texts. The modern city is a complex semiotic mechanism, a generator and relay of culture, a collection of heterogeneous texts and codes. The semiotics of the architectural space of St. Petersburg makes it possible to identify a colossal set of signs and symbols that are present in the architecture and urbanism of the city and influence the perception and interpretation of its space. Today, architects and city planning officials are faced with the dilemma of how to properly integrate modern architecture into the multi-layered semiotic environment of the city. Achieving a synergetic interaction between different and largely opposing aesthetics requires from their spokespersons a high professional culture and understanding of the essence of each of the cultural layers of this unique architectural environment.

According to Federal Law No. 384 «Technical Regulations on the Safety of Buildings and Structures», buildings are subject to requirements for insolation and sun protection, lighting, noise protection, indoor microclimate, etc. An analysis of the existing standard methods for calculating the corresponding positions made it possible to establish that these requirements are achieved without checking their mutual influence in the annual operation cycle. At the moment, there is no calculated indicator in the regulatory literature that summarizes the listed requirements in the form of a single final level of comfort in building premises. The study presents full-scale measurements of the microclimate parameters of a public building during the year, which made it possible to establish the characteristic periods of discomfort, their duration and causes. The results of the field study are compared with the calculated values obtained by computer simulation. It is shown that the use of the modeling method based on visual programming makes it possible to predict the duration of discomfort in the room and their periods in the annual cycle of operation, depending on the structural, thermal engineering, space-planning and other parameters of the building, as well as the climate of the construction region. It was found that thermal, light, insolation comfort is not constant throughout the year. The necessity of substantiating the comfort parameters through the duration of their provision during the year is revealed.

When glazing balconies and loggias, a closed air space is formed, the temperature of which, as a rule, is higher than the temperature of the external environment. An increase in temperature on a glazed balcony helps to reduce heat losses from the room adjacent to it. The article presents a method for calculating the average temperature on a glazed balcony, taking into account the conditional temperature of solar radiation formed during the heating period. The proposed method is based on the calculation of the thermal stability of the premises. The calculation of the average temperature for the heating period for glazed balconies of four main types for the climatic conditions of Kazan is given. It is shown that the conditional temperature of solar irradiation ranges from 2.99 to 3.78^оC for rooms of southern orientation and depends on the area of light-transmitting external enclosing structures and thermal performance of the surfaces of the room. It is shown that taking into account solar radiation as a factor in increasing the temperature on a glazed balcony or loggia can reduce the heat loss of a room that borders this balcony by up to 20%, depending on the configuration and thermal characteristics of the structures. The greatest effect of reducing the heat loss of the room is observed when glazing balconies, which have the largest area of light-transmitting structure fillings.

Sun protection devices of various types are used to ensure the sun protection of premises. Sun protection devices shield part of the solar energy and reduce overheating of the premises. At the same time, sun protection devices shade the light openings, thereby reducing the level of natural lighting of the premises. The current regulatory documents on sun protection and natural lighting practically do not take into account the loss of light in sun protection devices. In this regard, taking into account the loss of light in sun protection devices in order to ensure the normalized illumination of premises is an urgent task. The purpose of this work is to develop methods of accounting for sun protection devices in the design of natural lighting of premises. As a result of the research, a new concept was introduced, “the coefficient of openness of the sky of sun protection devices”, which shows the proportion of light that has passed through sun protection devices, and a method for determining it was developed. It is shown that the geometric coefficient of natural illumination for rooms with sun protection devices can be determined by the traditional method of Danilyuk graphs by enlarging their scale. The research results are illustrated with graphical and numerical examples.

The object of research of this article is a formalized model of automated technologies for the housing facilities life cycle stages on the example of the “Ecodom” construction system with the use of composite gypsum concrete. The goal is an object-oriented representation of the activities of decision makers in a given technology. At the same time, materials and structures of low-rise construction systems should create a capital internal living environment as close as possible to the natural physical and technical parameters of a “healthy” house, provided that the environment is favorable, and also be able to transform external relatively unfavorable environmental parameters into a comfortable internal living environment, taking into account the climatic features of the site. The research was carried out by the method of the automated technologies formalization modeling for the housing facilities the life cycle stages, in which the object orientation of the domain area is established in accordance with the standards, methods, algorithms, network models, the content of data- and knowledge bases, requirements to control algorithms and generation of the construction system “Ecodom” housing facilities. The result of the study is the substantiation of the possibility of creating an industrial low-rise housing construction innovative technological order that meets modern requirements of environmental friendliness, economy, energy efficiency, comfort of the living environment, requirements for construction systems, building information modeling technologies of capital housing facilities within its life cycle. It is concluded that to build an innovative technological order of industrial low-rise housing construction requires a partnership between the state and private companies, since in addition to efforts to create computer-based automated life cycle product management technologies, significant capital investments will be required in the industrial production of complete solution systems, necessary materials, domestic equipment (including robotics), that means the creation of a production base of construction systems, as well as the creation of a regulatory framework for the monolithic gypsum concrete construction technical regulations. The innovative technological order of industrial low-rise housing construction based on building systems using monolithic composite gypsum concrete will create competitive production of high-quality housing in the interests of the population and the construction industry of Russia.

Issues related to the stabilization of the construction industry under the sanctions of unfriendly states are considered. The sanctions pressure in all regions of the Russian Federation is manifested in a reduction in demand for final construction products, a slowdown in the dynamics of housing construction and a corresponding decrease in the volume of production of building materials, products and structures. As part of countering this negative situation in the Voronezh Region, measures have been developed to support the construction industry in critical areas – import substitution, investment, the labor market and logistics. The system of anti-crisis measures was formed on the basis of the analysis and scenario forecast of indicators of sectoral development – the volume of work by type of activity “Construction”, the commissioning of housing by developers, the commissioning of housing by the population, the volume of production of the main types of building materials and products. For each proposed support measure, an algorithm for its implementation was developed, the amount of necessary investments, sources of financing and responsible executors were determined, and associated risks were analyzed. It is shown that the support of regional enterprises and organizations of the construction industry in the context of sanctions should be based, among other things, on scientific and educational support provided by the leading educational institutions of the region. The presented materials are of interest to executive authorities, as well as to economic entities of the construction industry in various regions of the Russian Federation.
