Non-ventilated solar walls in older apartment buildings - full scale experiment. An evaluation of energy savings and thermal comfort; Uventilerede solvaegge i aeldre boligblok - fuldskalaforsoeg; En vurdering af energibesparelse og termisk komfort

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)}
