A method for optimizing facades design for enhancing daylight distribution in exhibition spaces

Abstract

Daylighting is a challenging architectural aspect that is usually avoided in exhibition spaces. This is due to the high variation over time and being influenced by spatial variations, which may affect exhibits sensible to light. Thus, when introducing daylight in such spaces, there should be a special concern on controlling light entering the space for each hour of the year and its impact on distribution pattern. This paper approaches the above problem through a simulation-based workflow to understand the effect of opening positions on daylight distribution pattern. Then, layout design was correlated to façade opening to optimize their positions according to the recommended lighting annual exposures. Results showed that daylight can contribute to object's illumination by 80% without exceeding the maximum allowable exposure limit.
