Abstract The new energy saving windows with heat-reflecting shields have been suggested, and for their practical use they need to be integrated into the automated system for controlling heat supply in buildings and the efficiency of their use tоgether with the existing energy-saving measures for different regions of Russia must be determined. The results of field tests of windows with heat-reflective shields in a certified climate chamber were used, as well as statistical climatic data of Russian regions were provided by RosHydroMet . The results were processed by the methods of mathematical statistics. Multivariant calculations of energy efficient windows performance in heating of buildings were carried out using the Mathcad software. The method to determine the minimum indoor air temperature under standby heating using heat-reflective shields in the windows was developed. The authors suggested two principles of position control of heat-reflecting shields in the windows: on schedule; by a signal from the ambient light sensor. The system of automated control of buildings heating with the use of heat-reflective shields (variable heat transfer resistance) was developed. The system allows to maintain different indoor air temperature (including the minimum-allowable temperature for standby heating) in all areas of the building by controlling the flow of heat transfer fluid in the heating device. The change in the fuel flow to the boiler influences on the changes in air temperature in all rooms. The annual savings of energy resources using heat-reflective shields for different regions of Russia were calculated. The use of the desinged windows with heat-reflective shields and the system of automated control can significantly reduce the consumption of fuel and energy resources in the utility branch as well as in the industrial sector.
