“…Discipline -Ventilation‖ is essential one in curriculum because of practical, scientific and laboratory researches. So, various conditions, problems of engineering systems in special climatic conditions are studied and investigated [1][2][3][4][5]. The analysis of students' performance on special disciplines gave us the following results (See Fig.…”

Experience of bachelors' training in heat, gas supply and ventilation in the Republic of Sakha (Yakutia) is considered in the article. Operation of engineering systems in the region is characterized by severe climate conditions: permafrost, difference in temperature from -71°C (winter period) to 38 °C (summer period), daily fluctuations of temperature, strong winds up to 50 m/s. Such special conditions impose the increased requirements to reliability and efficiency of house and public utilities. Training in special disciplines at NEFU is divided into three broad categories: theory, scientific activity and work practice. This article describes content and conditions of educational and scientific activity; level of applied equipment and material resources; results of students' scientific conferences, exhibitions and competitions; cooperation with employers and production structures. Keywords-training of bachelors, engineering, extreme climate conditions, engineering systems of buildings and constructions, heat and gas supply, ventilationI.

“…Nowadays, issues concerning improving the energy efficiency of the national economy are considered in the scientific literature as one of the most important aspects of quality of energy systems and attract the attention of an increasing number of scientists [1][2][3][4][5]. The results of numerous studies of foreign [6][7][8][9][10] and Russian scientists [11][12][13][14], performed in recent years in the field of energy economics, indicate that energy-service contracts, which have proven to be effective in world practice, are of particular importance. In Russia, the active implementation of energy service contracts continues, the mechanism of which is one of the most efficient types of public-private partnership.…”

The article analyses the results of implementation of the energy-service contracts in the Republic of Sakha (Yakutia). A review of the Russian energy service market has been completed. Real savings of energy carriers according to metering devices in public enterprises, indicating the effectiveness of the technologies used, have been achieved. The used energy-saving technologies and solutions that allow one to achieve economic effect are considered. It is established that the existing mechanism of energy service allows the renovation of buildings with high-quality engineering support and high thermal protection of the shell.

“…In the Far East region (Russia), with its high tariffs and seasonal supply of materials, the transportation costs for 1 ton of cement is three times higher than its actual cost [1]. This fact indicates the need to search for opportunities to extend the sphere of Portland cement usage by adding in its composition mineral or complex admixtures.…”

Abstract. Durability of hardened cement paste depends on chemical and mineralogical composition of Portland cement. The main factor for hardened cement paste is higher content of calcium aluminate and free calcium hydroxide, binding of which into water-insoluble compounds causes increase in resistance to water, frost and corrosion. The purpose of this research is to develop modifying admixtures to cement compositions based on local raw material -rock sand. Chemical and mineralogical properties of the source materials were studied using X-ray spectroscopy and X-ray diffraction analysis. Standard methods were used for defining physico-mechanical properties of sand and binder. Influence of the degree of mechanochemical activation of modifying admixture on the properties of binder and hardened cement paste made on its basis was studied. Research methods of scanning electron microscopy and spectral measurements were applied. The possibility of using admixture based on rock sand as a modifier was determined, its usage providing increase of strength, sulphate and frost resistance, which causes higher durability of cement concrete.
