Abstract
The control of glare in office environments is often retrospectively improvised using shading devices, typically internal blinds. Despite the leap towards energy efficiency goals, visual comfort is still being compromised in climates with high solar insolation resulting in intolerable glare. This paper discusses the visual performance of a novel glazing assembly comprising of two, independently switchable (solar Polymer Dispersed Liquid Crystal and Suspended Particle Device) interlayers intended to control the visible light transmittance into an indoor space. Readings of DGP in a full-scale test cell are presented together with an analysis of the visual appearance of the glass.
