RELIABILITY OF ENCLOSING STRUCTURES ACCORDING TO A GIVEN CRITERION OF THERMAL PROTECTION
Main Article Content
Abstract
The requirements of thermal protection, along with the requirements of mechanical strength and stability imposed on enclosing structures, are among the key requirements that must be taken into account, taken into account and monitored not only when developing building projects, but also after their construction, since it is these indicators that will determine the energy efficiency and cost-effectiveness of the construction projects being implemented. These requirements are presented in the current regulatory documentation of the Russian Federation and are described by certain mathematical models consisting of a set of parameters. When using these models, the expert (or the designer) can conclude whether the enclosing structure meets a certain requirement, for example, the requirement for reduced heat transfer resistance, or does not meet this requirement, however, he (the expert) cannot say and assess how reliable this structure is by one or another criterion of thermal protection or by a set of criteria. This article presents specific methods for determining the quantitative indicator of the reliability of thermal protection of enclosing structures and proposes to reduce the reliability assessment to a value or range of values that will range from 0 to 1. This approach will allow for a multifactorial assessment of the energy efficiency of enclosing structures and allows experts, based on the results obtained, to draw conclusions about reliability. enclosing structures according to various criteria of thermal protection.
