HEAT TRANSMISSION THROUGH ENERGY-ACTIVE DESIGN OF EXTERIOR WALL
The analysis of three design solutions for the use of solar radiation heat in architectural design is given: direct solar heating, a «massive wall» and a flat solar collector. The heat storage capacity of the second design solution and the energy efficiency of a more advanced design in the form of one of the options for a flat solar collector are evaluated. The design disadvantages of the «massive wall» are shown, which hinder its use in the design of energy- active buildings. It is established, that the use of a simplified version of a flat solar collector in comparison with the mentioned design solutions increases the intensity of absorption and transfer of heat of solar radiation into the room, and also allows to place a special heat-insulating layer in the exterior wall.
