The required level of thermal protection of enclosing structures of administrative buildings in the transport infrastructure in Russia and European countries

Abstract

Comparison of various standard values and calculation methods adopted in Russia and European countries has always aroused quite a lot of interest, and many works are devoted to this topic. However, the last comparisons were carried out quite a long time ago, and the purpose of this study is to compare the required level of thermal protection of the building envelopes of administrative buildings in the transport infrastructure in Russia and European countries according to the current regulatory documents to determine the ratio of these values to each other. The normalized values of the level of thermal protection of external enclosing structures are related to the degree-days of the heating period. Moreover, the definition of this value in Russia and the EU countries differ from each other. And it is possible to compare the level of thermal protection of enclosing structures in different countries only according to the same characteristic, that is, with the same (or very close) value of the degree-day of the heating period. Also, the level of required resistance to heat transfer of external enclosing structures in Russia is set taking into account heat-conducting inclusions in the enclosing structure, and in European countries without taking into account. That is, it is impossible to compare these two quantities in the original form - you need to take into account the design of the outer shell of the building.
