Abstract

With regard to solar walls, two profile systems were tested for tightness against rain penetration and for mechanical strength, and the stability of form of a transparent insulation material was tested at different temperatures. The test facility consisted of a system of sprinklers and suckers simulating rain and wind force. It was proved that Isoflex preserves its stability of form when heated to 98 deg. C during 35 minutes as well as up to 120 deg. C during 12 minutes. Its capacity for resisting UV radiation was considered sufficient. Results showed that total energy saved by constructing a solar wall on a SSE oriented gable was 6700 kWh during a moderate firing period, corresponding to 83 kWh/m{sup 2}. The saving for a flat with a solid outer wall behind the solar wall will be 2900 kWh or 125 kWh/m{sup 2}, while the saving in a flat with an insulated cavity wall will be 1900 kWh or 66 kWh/m{sup 2}. An external, extra insulation of 100 mm mineral wool will save 4000 kWh, corresponding to a saving of 60 kWh/m{sup 2}, 96 kWh/m{sup 2} on the solid wall and 38 kWh/m{sup 2} on the cavity wall.

The thermal indoor climate was satisfactory in the case of the solar wall. The surface temperature on the inside of this wall increased 1 to 3 deg. C in the course of the year. During a heat wave the temperature in the flat rose to 32 deg. C, also due to the solar heat through the windows (18% of outer wall surface). The conclusion is that the solar wall is a good alternative to traditional insulation of outer walls, especially in the case of solid outer walls. (AB)}
