ABSTRACT
Adaptive envelopes play a key role in space conditioning and solar heat gain (SHG); moreover, have great potential to conduce to building sustainability by reducing heating, ventilation, and air conditioning (HVAC) energy demand. A parametric approach using Rhinoceros, Grasshopper, and ClimateStudio accelerates advanced analysis to investigate the role of geometrical characteristics on daylighting performance in SE and SW orientations in Stuttgart. Results have shown that the increased usage of material has no significant impact on the illuminance level compared to the application of sun tracking factor. In fact, the triangular folded modules efficiently control solar radiation in response to time and season. An adaptive kinetic envelope has been proposed to reconfigure its geometry in response to changing weather conditions thereby optimizing daylighting performance as well as controlling the solar radiation in the urban area. Aiming for the optimal solution to indoor and outdoor environments, this paper focuses not only on the interactive performance of the adaptive shading system related to the environmental conditions and users’ needs, but also on the sustainable operation of the kinetic mechanism.
