Abstract: Simulation analyses for solar combisystems (domestic hot water production and space heating) with different levels of collector quality (atmospheric and evacuated flat-plate collectors) and different types of façade integration (direct, indirect) have been performed. For the direct integration of solar collectors into the building facade, a simple collector-facade model has been used (TRNSYS) while indirect integration with a naturally ventilated air gap between collector and facade has been investigated with a newly developed collector-facade model representing the air flow in the gap induced by wind or buoyancy (TRNFLOW). The highest performance has been achieved by direct integration of high efficient evacuated flat-plate collectors directly integrated into the façade.
