The strategic course on energy efficiency, resource saving, and environmental safety as a basis for sustainable development of our country brings to the forefront the issues related to ecological house construction or “green” construction. Now, these issues are of particular relevance and research and practical importance. In this article, the main principles (criteria) for ecological house construction have been defined, and an attempt has been made to formulate a normative and methodological justification for each of them, taking into account the generalization and analysis of the knowledge accumulated on this topic. The presented principles of ecological house construction are updated on the example of a specific territory and construction site. They are implemented in the construction business project of an autonomous energy-efficient complex “Eco-house” with innovative treatment facilities and resource-saving operation technologies in one of the most ecologically clean areas of the Moscow Region. The main objective of this project is to reach to a fundamentally new level of environmental and economic development of architectural and construction thought, considering the eco-house as a natural anthropogenic ecosystem with a positive ecological resource that provides autonomous existence, energy efficiency, resource saving and environmental safety as the main principles of sustainable development. The business project satisfies to all the town-planning, technical, sanitary-hygienic, environmental requirements for selecting a land plot for individual housing construction, its layout, construction technologies, construction materials, structures and products, residential buildings and premises, nature conservation facilities, resource-saving activities and recycling eco-house waste products into useful secondary products used hereafter in the eco-house processes of management and operation.

Introduction: in the article the estimation of new ecological safety biopositive polymer-mineral composite (BPMC) building materials obtained with the use of technogenic wastes is considered. This approach is one of the ways to solve the problem of improving the environmental safety of the environment. Materials and methods: BMPC environmental safety studies were performed using microstructural, X-ray and elemental analysis methods, studying physical and mechanical properties and fire safety. Man-caused wastes inventory and classificational ecological assessment by the lif e cycle was carried out. Results: the conformity of the Baikal region man-caused wastes (such as fly ash from heat-power engineering, aluminosilicate microspheres, isolated from bottom ash wastes, marble dust (microcalcite), industrial waste of polyvinylchloride (PVC), as well as small-sized mica waste in the form of vermiculite) to the basic characteristics that allow to use this wastes in the production of BMPC-products by extrusion as fillers. The man-caused wastes ecological utilization mechanism was developed. Composition of composite materials, in which industrial PVC waste is used as the matrix, and fly ash, ash microspheres, marble dust and vermiculite as fillers, were developed. The proposed technology for the production of BPMC products allows the use of technogenic wastes in a wide range in the composition from 20 to 60 %. The new biopozitive polymer-mineral composite products properties were studied. Conclusions: the conducted studies of the composition and properties of samples obtained using different types of man-made waste in the polymer-mineral composites production proved that the production of BPMC products ensures the building materials and environmental safety through the reliable and durable materials production that comply with regulatory requirements. According to the life cycle environmental safety assessment, the waste products obtained on the basis of waste have significant advantages in terms of a technical and environmental characteristics set.

Environmentally safe construction products are materials and products of construction purpose made of renewable natural resources and natural environment components with minimum spend of natural resources and energy, and the process of handling thereof (extraction of raw materials for production of the aforesaid materials and products, manufacture, transportation, use in engineering structures, processing, recycling, burial in natural environment) does not adversely affect neither humans nor environment. The article considers the basic historical stages of use of environmentally friendly construction materials in industrial and civil construction, starting from antiquity and ending with modern age. Review materials on the use of safe natural products such as wood, stone, thatch, peat, clay and other types of environmentally friendly materials in construction are presented. Properties of natural materials that ensure environmental safety of buildings, structures and premises, sanitary and hygienic requirements, coziness and comfort thereof for humans are analyzed. It is concluded that at present time the construction of high quality, comfortable, ecologically safe housing at affordable prices which is based on environmentally friendly technologies, resource and energy saving, construction materials safe for human health, should become one of the main priorities of economic and environmental policy of Russia.

In large cities, fuel consumption is growing rapidly, and therefore the number of filling stations. And they are a source of anthropogenic impact on the environment and represent current scientific and practical task, because recently no research was conducted into the optimization of monitoring systems in the construction of gas station storage tanks, and no activity on replacing the obsolete design with new storage tanks. In this regard, much attention should be paid to the creation of geo-environmental systems integrated assessment of the environment, as well as modeling and forecasting various negative situations. In the modern world, the creation of such systems is possible with the help of modern computer tools such as geographic information systems.

This article gives an overview of the analytical methodology for assessing the environmental safety in construction, the existing government programs in energy saving, and the analysis of the actual state of the investigated problem, proposed a method of assessment of environmental safety efficiency criteria of a city. The analysis is based on the data on housing and communal services of the City of Moscow. As a result of the consideration of the government programs and methods of assessing the environmental security in construction the conclusion was made that none of the programs reviewed and non of the methods include consideration of the relationship between environmental parameters of environmental security and energy efficiency (indicators of them are considered separately from each other). In order to determine the actual state of environmental safety analytical review was performed of energy efficiency programs of the government in Moscow and the methods of assessing the environmental safety of a construction. After considering a methodology for assessing the environmental safety of a construction, the author proposes to use the model for determining the indicator of efficiency of the city to ensure the environmental safety of the processes of life-support of the city, which takes into account the dependence of the parameters of environmental safety and energy efficiency. The author describes the criteria for selecting thr data on energy and environmental efficiency of the city. The article shows the sequence to identify the criteria for determining the indicator of efficiency of the city. In the article the author presents the results of ecological assessment of Moscow on the energy-ecological efficiency model, using the model defined performance indicators of the city to ensure environmental safety processes of life support of the city. The model takes into account the dependence of environmental safety parameters, environmental and energy efficiency. The correlation analysis of the effectiveness of the city of Moscow, the graphs for the regression assessment models of the data are described. The coefficient of efficiency indicators correlation of city support and the coefficient of life safety in the city are calculated. Performance indicator for Moscow in 2009-2012 is defined, which reflects the dependence of the processes of life support and life sustenance of the city. The proposed approach to the assessment of environmental safety may be used in the development of governmental programs on energy saving, as well as in the preparation of regulatory documents.

The authors analyze the problem of implementation of principles of "green construction" in the Russian Federation. Despite the availability of the appropriate legislation in the field of environmental safety of construction, there are no legal, social, or economic incentives that may boost development of "green" technologies.
Until recently, fundamentals of the state policy in the field of environmental protection of real estate development have not succeeded in motivating market players to implement advanced green technologies.
However, recently, the government has begun motivating the construction industry towards the use of "green" technologies. The first activity is aimed at improving the legislation and updating the international voluntary certification according to BREAM and LEED standards.
The result is the acceptance of the National Green Building Standard for real estate valuation that will open up new opportunities and prospects to the participants of the construction market. However, at the initial phase of implementation of "Fundamentals of the State Policy in the Field of Environmental Development of the Russian Federation", government authorities should provide their support to proponents of green buildings, including financial inflows.

Constructive, technical and technological reliability of major pipeline ensures ecological safety on different stages of life circle - beginning with project preparation activities up to the end of major pipeline operation. Even in the process of transition into new life circle stage, no matter if the pipeline needs major repairs or reconstruction, such technical and technological solutions should be found, which would preserve ecological stability of nature-anthropogenic system. Development of ecology protection technologies of construction, reconstruction and major repairs of main pipelines is of great importance not only for a region, but ensures ecological safety across the globe. The article presents a new way of trenching the main oil and gas pipeline, preservation and increase of ecological safety during its service. The updated technological plan is given in the paper for overhaul of the main oil and gas pipeline using the new technology of pipeline trenching. The suggested technical solution contributes to environment preservation with the help of deteriorating shells - the shells’ material decomposes into environment-friendly components: carbon dioxide, water and humus. The quantity of polluting agents in the atmosphere decreases with the decrease of construction term and quantity of technical equipment.

The article states that the use of spoil heaps (coal mining waste) in the production of structural ceramics is expedient. It shows the reduction of negative ecological effects during the life cycle when coal mining waste is used in the initial blend for the production of structural ceramics. It shows that the development of the recommendations for the use of coal mining waste in the production of structural ceramics is an urgent issue as far as the use of coal mining waste in the production of structural ceramics can lead both to the achievement of resource saving and positive ecological effect and to the undesirable decrease of the basic physical and mechanical properties of the final products when the structure of the mix is inappropriate. In order to develop these recommendations the authors have examined the microstructure, mineral composition and physical and mechanical properties of structural ceramics produced with the use of coal mining waste, which effect the consumer properties of the target material. As a result of the research the authors have made the conclusions about the nature and degree of impact of coal mining waste quantity on the physical and mechanical properties of construction ceramics. The comparison of the data received during the measurement of the basic physical and mechanical properties of construction ceramics with the results of the research of microstructure, elemental and mineral composition of the samples has shown their correlation.

Resource saving, ecological safety, rational use of natural resources and environmental protection are currently the priority tasks in terms of implementation of the course towards a sustainable development of the Russian state. Transformation of waste into secondary raw materials for the manufacture of environmentally friendly construction products and other products makes it possible to resolve two problems at once: preserve valuable resources and reduce the environmental load. The article presents theoretical provisions and background for methodology of forming a model of complex system of construction waste treatment in terms of modern tasks for creation of new economically efficient, resource-saving, ecologically safe and waste-free technologies and processes in the industry, as well as the requirements of regulatory acts in the sphere of environmental safety, hazardous waste management, environmental protection and rational use of natural resources. The final target indicator of scientific research in this sphere is the minimization of waste amounts dispatched to burial facilities due to creation of optimal, reasonable from the technical-and-economic point of view, chain of complexes for treatment thereof, preliminary preparation for further recycling, including sorting, dismantling, cleaning, and disposal. Comprehensive assessment and subsequent reasonable selection of optimal scientific methods of research of factors, indicators and restrictions that form the constituent elements of methodology of creation of the economic and managerial model of the complex system of waste treatment, will be continued.

Subject: technical and economic processes and aspects of handling wastes and secondary material resources; stages of transition of anthropogenic object of environment to wastes and secondary material resources; technical possibility and economic feasibility of using secondary material resources as a secondary raw material for making products, providing energy, works, services. The problem of economy and rational use of material and power resources is relevant and significant within the limits of maintenance of a strategic course of Russia on innovative sustainable development. In this article, issues of actualization and harmonization of the regulatory and legal base in the field of management of wastes and secondary material resources are considered from the viewpoint of maintenance of minimization of waste formation and maximum use of secondary material resources in an industrial-economic cycle, provision of economic incentives for innovative activity in the given field. The actual multi-plan problem, chosen here as a topic of research, concerns regulations in management of wastes and secondary material resources in construction complex, in which economic, civil-law, ecological, social, industrial and legal relations are closely coordinated and define a subject of the present research. Production and consumption waste is a dangerous anthropogenic object of the environment but at the same time, it is a valuable secondary material resource. The non-use of wastes to be recycled as secondary raw materials for energy generation, production and, as a result, their increasing accumulation in the environment causes irreparable harm to natural objects and human health due to their dangerous properties. Research objectives: scientific and methodological substantiation of legal regulation, economic basis for formation of wastes and secondary material resources management system (on the example of construction complex and building materials industry). Materials and methods: for conducting scientific research, we used guidance documents, standards, techniques, methodological recommendations, project and regulatory documentation in the field of environmental protection and waste management, published data and materials of domestic and international research on this topic. Methods of scientific research employed here are based on the use of comparative analysis, expert methods of indicators assessment. Results: we formulated proposals to update and harmonize the conceptual apparatus in the area of management of secondary material resources in the form of amendments to the current legislation, as well as proposals with regard to economic regulation methods in the area of wastes and secondary material resources management for introduction into the plan of implementation of the “Strategy for Development of Industry for Processing, Recycling and Decontamination of Production and Consumption Wastes for the Period until 2030”, approved by the legal act of the Government of the Russian Federation. Conclusions: the formulated scientific and practical proposals on the solution to the issue of handling wastes and secondary material resources can be used in formation of regulatory and legal framework and for planning actions in management of wastes and secondary material resources within the limits of implementation of the “Strategy for Development of Industry for Processing, Recycling and Decontamination of Production and Consumption Wastes”.

The authors demonstrate that the number of buildings in the world exceeds one billion according to the statistical data; their potential negative impact on the environment can be disastrous; moreover, the main cause of the ever-growing demand for buildings consists in the constant growth of the world population that makes the global environmental situation even more complicated.
As a main conception, the authors focus on the concept of sustainable development. They consider that the core idea of this concept is that the present-day generation should do everything in their power to preserve the natural environment and its resources for the future generations. The authors mention that back in the middle of the 20th century academician V.I. Vernadsky formulated the concept of the noosphere closely linked to the notion of sustainable development.
According to the authors, "green" construction can be considered as a vehicle for sustainable development of territories that accommodate construction sites. The authors define "green" construction as a comprehensive system of knowledge structured on the basis of design and construction standards. "Green" buildings demonstrate their high construction quality along with minimal costs and maximal comfort. Although a "green" technology is a new and not the simplest way of development, it has proven its incredible efficiency.
The major achievement of the authors consists in the classification of principles, approaches and available technologies that can be applied or are applied in the "green" construction to ensure the environmental safety of construction activities. The authors have also selected environmental, economic and social benefits of "green" construction and provided their recommendations concerning the implementation of "green" technologies in Russia.
