The paper discusses the processes of radiant heat transfer occurring in the solar cell-room of the «Insolar» solar passive system, which parameters are optimized under to the inclusion of solar heat-generating elements – solar receivers-rubicubooctahedrons – in the design of the outer shell of the house. Due to the optical-geometric proper-ties of the rubicubooctahedron, there are two technological possibilities for converting solar radiation into low-grade heat, which is used for air heating of premises.  Part of the solar radiation energy converted in the rubicubooctahedron enters the heat-accumulating structure of the inner wall due to the convective flow diverted through the air ducts. A particle of solar radiation, passing through the translucent edges of the solar receiver, enters the adjacent room – the solar cell – and heats the air in it as a result of radiant-convection heat exchange. Analysis of heat transfer processes shows that the Increased efficiency are due to the boundary conditions of the adjacent components of the solar passive system
