In modern office buildings, the interior layout dramatically has shifted to open planning ,sometimes involving tearing down full height walls and replacing them with varying-height partitions or panels. The visual environment is influenced by the blocking effect caused by the presence of the interior partitions, creating light attenuation and shadows. The negativeness of interior partitions in terms of lighting can be mitigated by adapting light shelves. They improve the uniformity of natural light in a space by reducing the level of illumination near the window and redirecting light deeply over the partition. This paper aims to analyze the interaction between partitions and light shelves based on their geometric and optical characteristics. Their role, that is, a tradeoff between optimal distribution of the daylight and glare control has been evaluated simultaneously. A series of computer simulation deals with the basic geometrical design elements of a commonly used light shelf and partition configurations. As is shown in the results, for best distribution, light shelves should be located as low in a space as possible without causing glare, typically above standing eye level. In addition, more uniformity of light distribution can be improved by extending of the shelf and reflectance of the shelf and higher ceiling height might play a role in increasing the effectiveness of light shelves. |
