Evolution of regulations for thermal protection of buildings

The article is devoted to the study of regulatory documents in the field of thermal engineering in construction and the development of regulations for thermal protection of buildings. The object of the research is the standard documentation in the field of thermal engineering in construction. A retrospective analysis of the norms and requirements for thermal protection of buildings was carried out by identifying qualitative changes in the content of standard documentation. Building codes and regulations, Code specification, Federal laws and Government decrees have been adopted as such regulatory documents for this study. The documents that influenced these changes are considered. The normative requirements of the past years in the field of building heat engineering have been systematized. Six stages of the formation of norms for the thermal protection of buildings are determined, based on changes in the formulas for determining the resistance to heat transfer of enclosing structures and the introduction of the characteristic of the degree-day of the heating period, depending on the climatic features of the region. Trends in the development of standards for thermal protection of buildings have been determined. The main goal is to reduce the specific characteristic of heat energy consumption for heating and ventilation, which requires a change in the requirements for thermal protection, in particular, an increase in the required resistance to heat transfer, which can contribute to updating the existing set of rules for thermal protection of buildings.
