Abstract


Problem. Today the problem of the power consumption reduction in the private apartments has become increasingly topical and stimulated the development of power-saving technology. Power-saving technology allows to solve several problems at the same time: economy of energy supply, resolution of the housing and communal services problems, reduction of environment pollution, enterprise efficiency extension.

Literature review. Over the years in Europe and Scandinavian countries power-saving technology during construction and reconstruction of the buildings have been used. In these countries the necessary legislative standards were adopted. They take into consideration economic interest of the accommodation owners and investors. The main goal of those standards is the extension of power-efficiency level, which has been achieved with the help of effective heat insulation application. The topicality of power-efficiency concept in European countries is confirmed by the standards that have clearly stated all the requirements. Generally they ensure the accomplishment of the main condition which is the utilization of efficient constructions where realization of the power economy requirements is guaranteed.

In Ukraine there are state building standards, particularly which determine requirements to the heat engineering indicators of walling and to the order of their calculation with the aim to ensure efficient consumption of energy resources for heating, hygiene and sanitary parameters of the indoor climate, durability of walling during the maintenance of the building.

Aim. To analyse solutions given to heat insulation of outdoor walling as well as to determine heat insulation characteristics of the concrete and other energy efficient materials.

Main objectives: to study domestic and foreign experience bringing solutions to heat insulation of outdoor walling; to carry out the search of more efficient architectural and constructional solutions to heat insulation of buildings; to analyse thermal and physical characteristics of domestically produced concrete and French originated concrete Thermedia 0.6 B.

Conclusion: Domestic and foreign experience of heat insulation solution for outdoor walling has been studied. The search of more effective architectural and constructional solutions to heat insulation of buildings has been accomplished. Thermal and physical characteristics of domestically produced concrete and French originated concrete Thermedia 0.6 B have been studied.

European researchers are constantly working on the concept of new materials that possess both mechanic proprieties and high energy indicators that not only improve the comfort of dwellings or reduce heat losses, but also decrease the cost price of the accommodation. In Ukraine this problem is brand new and very important for the future. It is necessary to carry out a series of researches regarding the choice and application of currently used technologies depending on geographic, economic and architectural conditions in our country.
