Daylight patterns as a means to influence the spatial ambiance: a preliminary study

This contribution focuses on perforated façades, investigating the effect of the façade and the resulting daylight pattern on the perceived spatial ambiance. The daylight conditions, as well as the geometry and regularity of the façade pattern are manipulated in an immersive virtual space, producing different conditions. A preliminary study was conducted, where subjective evaluations of the virtual space were recorded across six variations of façade pattern and sky type. The results indicate that the façade pattern characteristics have an impact on the perceived spatial ambiance, underlining the need to investigate further the perceptual aspect of the spatial and temporal diversity of light in space through experimental studies.
