| dc.title | Optimizing daylight performance in educational buildings : a comprehensive analysis of design strategies | en_US |
| dcterms.abstract | Daylight is an important parameter in learning environments, as it impacts energy efficiency, visual comfort of occupants, cognitive performance, and well-being. In such hot, humid climates as Guangzhou, control of the availability of daylight and minimization of glare with consideration of thermal loads is of special concern, especially in deep-plan classrooms. The objective of our research was to explore how the facade components, such as window-to-wall ratio (WWR), orientation, window shape, and shading devices, affect daylight performance of a multi-storey school building, and how daylight exposure affects student learning, well-being, and health. A parametric daylight analysis by the software Insight simulated the assessment of Useful Daylight Illuminance (UDI), Spatial Daylight Autonomy (sDA), and Annual Sunlight Exposure (ASE) for differently-floored, oriented buildings. These quantities were compared with standard literature benchmarks for finding gaps in its annual daylighted space and maximizing strategies for them. | en_US |
| dcterms.abstract | Increased such facade WWR was determined by the study to improve daylight autonomy but to increase glare and ASE failures, while deep-plan spaces with low light levels were typified by compromised visual comfort as well as low circadian stimulation. Static sunshades and rectangular windows were inadequate in controlling daylight quality. Integrated, climate-responsive facade solutions like dynamic shading, optimized window geometry, and reflective surfaces were determined by the study to be required in the achievement of healthy, productive learning environments in the subtropics. | en_US |
