One of the laboratory’s focal points is perception, investigating how people perceive their surrounding environment. In the field of daylighting, this research refers to the impacts of luminous conditions on the aesthetic and emotional evaluation of space. LIPID’s research in this domain aims to identify, quantify and predict these perceptual impressions of daylight across space and time. In the same scope, part of the laboratory’s activities focus on façade design, with a two-fold aim: the investigation of relationships between façade characteristics and perceptual impressions, and the study of how these impressions influence the occupants’ satisfaction and perceived comfort.
