Climate based simulation of different shading device systems for comfort and energy demand

Jan Wienold, Francesco Frontini, Sebastian Herkel

Abstract: This study investigates in detail conventional and advanced shading devices. Thermal and visual aspects are considered as well as advanced control strategies. The systems are compared regarding energy balances, daylight provision and visual comfort aspects (glare, view contact). Outside mounted systems offer in all investigated cases best solar protection. A combination of external shading and internal glare protection can reduce the overall energy demand by more than 25% compared to a solar control glazing and/or only internal mounted shadings. High reflective internal mounted shadings cannot reach the performance of external shadings. They can improve the cooling demand compared to a standard internal mounted blind system, but only if high quality sufaces are used.
