The daylighting benefits of semi-enclosed atrium: based on the case study of Siyuan Centre
The daylighting benefits of semi-enclosed atrium: based on the case study of Siyuan Centre
This report examined Siyuan Centre's light environment at Nottingham's Jubilee Campus. Analysing building orientation, glazing structure, environmental strategy, visual comfort, and passive energy-saving design met sustainable standards—daylight factor, spatial daylight autonomous, and functional daylight illumination. We explored how atrium daylight passively improves indoors. On-site measurement, formula validation, and software simulation tested the atrium and two typical spaces. The test results showed that direct illumination caused glare in the atrium through the wide glazing, exceeding the comfort range. That affected nearby spaces, especially the two open-plan offices that use the atrium for indirect lighting. As an essential light source for them, the atrium provides an uneven and unstable light environment. This study proposed optimisation strategies for shading devices and section design to improve light distribution and reduce glare and simulated space performance after applying them.

Abstract
This report examined Siyuan Centre's light environment at Nottingham's Jubilee Campus. Analysing building orientation, glazing structure, environmental strategy, visual comfort, and passive energy-saving design met sustainable standards—daylight factor, spatial daylight autonomous, and functional daylight illumination. We explored how atrium daylight passively improves indoors. On-site measurement, formula validation, and software simulation tested the atrium and two typical spaces. The test results showed that direct illumination caused glare in the atrium through the wide glazing, exceeding the comfort range. That affected nearby spaces, especially the two open-plan offices that use the atrium for indirect lighting. As an essential light source for them, the atrium provides an uneven and unstable light environment. This study proposed optimisation strategies for shading devices and section design to improve light distribution and reduce glare and simulated space performance after applying them.
