Shaping light to influence occupants' experience of space: A kinetic shading system with composite materials

Abstract

Adaptive kinetic faades are systems capable of modifying their shape to optimize their behavior regarding real time outdoor and indoor conditions. They are typically evaluated based on quantifiable physical parameters such as illuminance levels, with little attention - for lack of evaluation criteria - given to subjective appreciation of the faade and the resulting daylight patterns. The present study investigates the daylighting performance of a kinetic shading system based on simulations combined with physical mock-up testing, to assess its viability as an alternative shading solution that complements conventional functions by enhancing the occupants' experience of the space. Based on performance assessment and perceptual studies, the shortcomings of traditional blinds are identified and a promising prototype design, controlling the blinds' opening by means of torsional deformations, is proposed.
