Abstract

This paper develops a framework that exploits effect of infill height design variation of 4D-printed wood in adaptive facades on daylight performance according to LEED_V4 criteria. The significance of 4D-printed wood lies in the ability to program its response behavior to fluctuations in humidity levels with zero-energy consumption. Hygromorphic motion response is analyzed by evaluating its angle of curvature using image-analysis. Parametric script is developed to evaluate the effect of louvers number and their shape morphology on daylight performance. Results revealed that flat 4D-printed hygromorphic-based materials followed by 0.6mm infill height in the middle of the sample increase daylight performance.
