PERSONAL LIGHTING CONDITIONS OF OFFICE WORKERS: INPUT FOR INTELLIGENT SYSTEMS TO OPTIMIZE SUBJECTIVE ALERTNESS

Ph.D thesis by Juliëtte van Duijnhoven, Technische Universiteit Eindhoven (NL)

Lighting controls in offices are still mainly focused on energy savings. However, focusing on a potential productivity increase of office workers would lead to much higher savings in company costs. A less alert office worker performs a task worse compared to a more alert office worker. This project aimed at developing input (personal lighting conditions, predictors of personal lighting conditions, and its relation with subjective alertness) for intelligent systems to optimize […]

DISCOMFORT GLARE PERCEPTION FROM DAYLIGHT: INFLUENCE OF THE SOCIO-ENVIRONMENTAL CONTEXT

Ph.D. thesis by Clotilde Pierson, Université Catholique de Louvain (BE)​

“Space and light and order. Those are the things that men need just as much as they need bread or a place to sleep.”[Le Corbusier]

Exposure to light, and especially to daylight, has much to offer. Regarding buildings’ occupants, daylight has been shown to boost performance, improve sleep, provide a connection to the outside, increase comfort, lessen agitation, and reduce depression. Regarding buildings, daylight enhances the aesthetics of a space and […]

MEASURING AND MODELLING EQUATORIAL LIGHT

Ph.D. thesis by Priji Balakrishnan, Singapore University of Technology and Design

The distinctiveness of natural light in a built environment is a confluence of its physical feature––buildings, trees, and the ground––with its region-specific daylight source––the sun and the sky. The colours and patterns we see around us at different scales of cities, neighbourhoods or streets is the result of these complex interactions between the physical features and characteristics of its daylight. The current daylighting modelling workflows do not account for […]

PERCEPTUAL EFFECTS OF DAYLIGHT PATTERNS IN ARCHITECTURE

Ph.D. thesis by Kynthia Chamilothori, Laboratory of Integrated Performance in Design (LIPID), École Polytechnique Fédérale de Lausanne (EPFL)

The profound impact of daylight on occupants is broadly recognized in the fields of architecture and lighting. In particular, the façade and its interplay with light is a central design element, while the diversity of daylight in space is widely acknowledged as a source of interest and stimulation that enriches our spatial experience. However, little is known about how the façade geometry and […]
