The work notes the development of non-traditional energy sources in Ukraine. There is a need to improve existing solar collectors and combine these units with structures of external fencing for energy-efficient buildings. Taking into account the popularity of construction with an increased area of glazing, the paper suggests the design of solar collector combined with the glass facade of the building. It gives data about change of the heat carrier temperature at the outlet of the solar collector. It was investigated that the developed model of the solar collector allows generating 132 W/m2 under the effect of the simulated solar energy intensity of 300 W/m2. Also, it was studied that the solar collector combined with the glass facade of the building has an average thermal efficiency of 43 %. This efficiency was achieved for cloudy days or for morning and evening heat supply, i.e. when the incoming solar energy to the solar collector is not maximal.
