Integrating interactive kinetic façade design with colored glass to improve daylight performance based on occupants’ position

Highlights

• It is the first time that a kinetic façade integrated with colored glasses to improve occupants’ daylight performance.

• The interactive kinetic façade triggered by sun timing and occupants’ positions provides real-time daylight control.

• Using parametric decentralized and hierarchical rotating movements, shows more improvement in daylight performance.

• The integrated approach revives the passive strategy of colored glass and facilitates its multi-functionality.

Abstract

The dynamic nature of daylight and occupant's position can cause some issues such as heat gains and visual discomfort, which need to be controlled in real-time operation. Responsive facades have been pervasively used for preventing daylight glare and meeting daylight performance requirements. However, some passive strategies such as the colored glass of the Orosi typical architectural elements used in Iranian central courtyard buildings have the potential to filter excess daylight, as well as providing other functions such as aesthetics and privacy. This paper explores, for the first time, the possibility of coupling a kinetic façade with colored glasses to improve the daylight performance. This research builds on a combination of relevant literature and parametric simulation to investigate the development of integration of colored glass from Orosi with interactive kinetic façades, triggered by sun timing and occupants' positions. In total, 72 interactive kinetic façade cases are parametrically simulated, and their daylight performance is evaluated through climate-luminance based metrics. The simulation results confirm the high performance of the interactive kinetic facades for improving daylight performance regarding a base case. The integrated interactive kinetic façade with colored glass provides a real-time adaptation of the multifunctional passive strategy to sun timing and occupants' position. The integrated interactive kinetic façade with colored glass which uses parametric decentralized and hierarchical rotating (0–45°) movements, shows more improvement in daylight performance compared to other cases based on climate-luminance based metrics evaluation.
