IMPROVEMENT OF EXTERNAL FENCING STRUCTURES AS A SOURCE OF HEAT LOSS IN BUILDING

Abstract

In this article the main problem of energy efficiency in building is discussed. Building sector is one of the most important and the great consumer of energy recourses not only in Ukraine but in the other countries. Many scientists in the world discuss this problem and look for ways to solve the problem of reduce resource and energy intensity in construction industry. Much of the heat energy loss occurs precisely because of the external enclosing structures. The legislative regulation of thermal stability normative values of window constructions is presented.

The development of modern construction in terms of energy efficiency and energy saving should take place in a comprehensive way covering various areas of structural elements of a building improvement. First of all, it concerns the introduction of new types enclosing structures that are characterized by an increased level of thermal resistance, according to State Building Codes (SBC) V.2.6- 31: 16 Thermal insulation of buildings. The new version of this document introduces the improved requirements for energy efficiency and thermal engineering indicators of building structural elements.

Also the comparison analyse of the heat transfer coefficient for external enclosing constructions in Ukraine and Finland has been made.
