Collector Tilt Angle

All results presented in this paper were simulated using solar thermal collectors integrated into the south facade (collector tilt angle = 90°). Heat losses from the building can be reduced because the effective u-value of the wall with integrated collector is reduced even when solar radiation is low. In addition, overheating of the collectors during times of stagnation in summer can be avoided.
