Using additives with water absorbing characteristics enables us to increase the amount of water in natural basins and significantly decrease the amount of water for agricultural usage. Despite various additives already existing, they are yet to be commonly used due to high cost price, complex technology, toxic impact and instability in biological and atmospheric conditions. However, the «Natlen» composite, which is a naturally based additive, is ecologically safe. It has a long shelf life, is cheap and provides high antifiltering rates. The composite is eruptive with dispersity of any type and is jelly when boosted. In an antifiltering layer it never cracks under static and dynamic influences. It has no seam and is resistant to aggressive liquids. It is ecologically safe. «Natlen» composite is recommended for building water basins in pastures, where it can particularly be used to satisfy the demand for drinking water for cattle.

The article presents the results of studies aimed at clarifying the heat engineering calculations of energy-efficient residential buildings in the mountainous regions of Armenia. The regular changes in climatic factors of mountainous conditions at the altitudes of 800-1000 m above sea level were determined from the statistical and regulatory data of the Republic of Armenia using the method of statistical and correlation analysis and mathematical modelling. A quantitative evaluation of changes in climatic factors of the mountainous conditions was carried out which improved the accuracy of heat engineering calculations, to identify the costs of optimal energy consumption and to reduce the cost price of building energyefficient houses. The coefficients of the dynamics of changing climatic conditions of the Republic of Armenia, given in the article, are recommended to be used in the heat engineering calculations of the buildings when reducing the energy capacity of houses, construction costs and increasing the energy potential of the Republic of Armenia.
