Raising of problem. Today, in all spheres of our life we can constate the permanent search for new, modern methods and technologies that meet the principles of sustainable development. New approaches need to be, on the one hand more effective in terms of conservation of exhaustible resources of our planet, have minimal impact on the environment and on the other hand to ensure a higher quality of the final product. Construction is not exception. One of the new promising technology is the technology of 3D -printing of individual structures and buildings in general. 3D-printing - is the process of real object recreating on the model of 3D. Unlike conventional printer which prints information on a sheet of paper, 3D-printer allows you to display three-dimensional information, i.e. creates certain physical objects. Currently, 3D-printer finds its application in many areas of production: machine building elements, a variety of layouts, interior elements, various items. But due to the fact that this technology is fairly new, it requires the creation of detailed and accurate technologies, efficient equipment and materials, and development of common vocabulary and regulatory framework in this field. Research Aim. The analysis of existing methods of creating physical objects using 3D-printing and the improvement of technology and equipment for the printing of buildings and structures. Conclusion. 3D-printers building is a new generation of equipment for the construction of buildings, structures, and structural elements. A variety of building printing technics opens up wide range of opportunities in the construction industry. At this stage, printers design allows to create low-rise buildings of different configurations with different mortars. The scientific novelty of this work is to develop proposals to improve the thermal insulation properties of constructed 3D-printing objects and technological equipment. The list of key terms and notions of construction by 3D-printing and 3D- modeling. Practical value. Developed in this work equipment and materials allows in the nearest future to move from theory to practice and implement such effective method of construction as the technology 3D-printing.

Purpose. The purpose of the presented research is to discuss the key directions for the reformation of energy management in support of sustainable development policy implementation under conditions of transitional economy. In accordance with this aim the following objectives were formulated: 1) to analyse the experience of the EU and European countries, which have implemented the energy efficiency concept; 2) to identify the main methods for the implementation of energy efficiency concept in a transitional economy; 3) to suggest conceptual approaches for balancing targets of energy saving and economic growth in Ukraine. Methodology. The main arguments in the article are developed by analysing scientific papers on the issue of energy efficiency in the context of sustainable development, through comparative analysis of statistics in the area of energy consumption, energy efficiency and economic growth in various regions and countries, and by analysing experience of different countries in this field, Germany in particular. Conclusions. This article analyses the relationship between energy intensity and GDP growth, reviews the contemporary model for energy efficiency in the EU and studies differences between energy policies in various regions and the EU. The system approach allows to identify the main methods and measures that ensure the effectiveness of energy policy in Germany, which can be considered as useful for Ukraine. Originality. The study reviewed and analysed the main methods and measures that ensure the effectiveness of energy policy in Germany, including the domains of regulatory policy, funding, market instruments. Practical value. The proposed system of methods and measures may be useful for the planning of actions towards strengthening the capacity of energy efficiency in the conditions of the transition economy.

Purpose. Key challenges and barriers of mining machinery enterprises in the context of forming sustainable supply chains in the mining industry are specified. Methodology. The algorithm of forming the industrial relations, which are carried out by the enterprises of mining machinery in order to increase the sustainable development of a mining industry, is offered. Conclusions.. Modern supply chains are confronted with dynamic trends and developments that are hard to predict. In order to respond to these changes and remain competitive advantage, companies should be able to identify and understand new sustainability issues in their branches. It is established that in the conditions of globalization of the market and the general orientation of Ukraine’s economy to the European principles of development, for mining machinery enterprises a proof of the commitment and observance of requirements of energy efficiency, i.e. energy saving, energy safety and social energy responsibility are very important. Supply channels should increase not only energy efficiency, economic and production stability of the company, but also strengthen the stability of all participants in the production chain, as well as other stakeholders (business partners, customers, investors, local communities, etc.). Originality. The interrelation of an indicator of energy efficiency in forming sustainable supply chain in a mining industry is established. Practical value. Using the principles of sustainable development in the forming of value chains will improve energy efficiency of industry in general; provide a competitive advantage to entry into the global production chains in terms of European integration of Ukraine.

Problem statement. Nowadays it is difficult to see a typical, old peasant house, or different types of national confident buildings. It will take a little time and some monuments of national architecture will be difficult to find. Meanwhile, rural housing was the most massive object of traditional construction. It embodies the best achievements and experience of national architects; it is of great value for the history of Ukrainian culture, history of Ukrainian art, architecture and ethnography, sustainable construction. National art of peasant house construction of Prydniprovsk region of Ukraine, is multidimensional space and time in an array of hand-made Ukrainian art is a national architecture, its decoration, clothing filling of the interior of the house and estate, as well as plastic and spatial formation, determining loci ritual of family life of Ukrainian village since the ancient times to the present. Analysis of publications. The first publications about the Ukrainian national housing, was made in the late nineteenth - early twentieth century. These were the works of ethnographers and historians M.Sumtsova [17] and D. Bagalіya [1-4], G.Lukomskogo a little [12]. B. Kharuzin’s work is interesting in the context of our study .[19]. The interesting materials were found by us in the series of publications that have appeared in the end of XIX and beginning of XX centures and are associated with vital trend to build fire-resistant housing, and ukrainian peasant house was such kind of housing. "Nowadays such kind of peasant houses and storages are put because they cheap, strong and good and the most important is to be resistant to fire. Houses with brick and stone trying to be built by reach people, and houses with the clay and saman are built by poor people,they are elegant, strong, cheap long- existed and non-flammable " that is stated in the foreword to a small edition by I. Ulashivsky "Saman building" [18]. A small booklet" Valkovi Building (with 20 figures into text). F.S. Dudko also describes in detail tehnology of ukrainian peasant houses construction as the safetiest and the cleanest houses of present. In the 70th of the XX century, works began to appear devoted to the study of nation architecture in Ukraine. The features of construction of one or another region, the types of peasant houses, their interior; construction of farm buildings, equipping of the yard were considered in this work. Among them A. Danyluk "Closed yards in Polesie" [6 -7], A. Danyluk and M. Shpak "Traditional and new in boikivskyi housing construction" [8], M. Strunka "Ukrainian national housing of Mykolaivshchina" [16], M. Manurevich “Gagauz nation housing…”[14], Z. Petrova "Rural houses in the Carpathians" [15] and others [11; 13]. The purpose and the main directions of our research is to study the complex technology of the walls construction of the Ukrainians’national housing of Middle and Lower Naddniprianshchyny of Ukraine (of Prydniprovsk region) of the end of XIX and middle of the XX century, as the Dnipropetrovsk region belongs to this historical and geographical, industrial and economic region.
