Abstract

The dependence of the Republic of Armenia on fossil fuel imports, namely natural gas from the Russian Federation, forces specialists to develop and implement effective measures to reduce the physical volumes of imported fuel, and therefore the required financial resources. Although the price of gas in the Republic of Armenia is low compared to world prices, in the context of low solvency of the population, special attention is paid to it. And since such problems are of national importance, a study was conducted to study the thermal characteristics of 9-story panel typical buildings constructed and operated in various climatic zones of the Republic of Armenia. The study showed that in different cities of the Republic of Armenia, depending on climatic conditions, thermal engineering data of enclosing structures and the cost of thermal insulation material, the optimal thickness of the thermal insulation layer will be, in particular, expanded polystyrene (EPS) Gyumri 0,15 m, Yerevan 0,12 m, Vanadzor 0,13 m, Kapan 0,1 m, Sevan 0,12 m, Hrazdan 0,16 m and extruded polystyrene (XPS) Gyumri 0,11 m, Yerevan 0,1 m, Vanadzor 0,11 m, Kapan 0,08 m, Sevan 0,1 m, Hrazdan 0,11 m. As a result, the application of insulation layers in construction leads to a significant reduction in the consumption of organic fuels and electricity in heating systems over the course of the year. Depending on the external air temperature during the summer months, the duration of the season, the number of degree-days, the costs in individual cities vary. This means that when determining the optimal thickness of the insulation layer, it is necessary to consider it over the entire year.
