The article discusses issues related to improving the energy efficiency of translucent structures (hereinafter referred to as windows) in the construction of buildings in the Republic of Kazakhstan. An analysis of the current regulatory requirements for the thermal insulation of windows and other translucent structures, depending on the climatic conditions of the construction region, was carried out. The authors propose a schematic map of the climatic regions of the Republic of Kazakhstan and stricter values for the thermal resistance of windows depending on the degree-days of the heating period, which will significantly reduce heat loss in buildings and cut heating costs. Calculations of potential energy savings and economic benefits from the introduction of energy-efficient windows are presented, and schemes for the certification and labeling of windows by energy efficiency class are proposed. The work is based on an analysis of national standards and international experience and is aimed at supporting sustainable construction and the implementation of Kazakhstan’s climate commitments.
