Author: Beng Wee (Steward) Lim Email: stewardlim1@hotmail.com Until recently, the technology to redirect natural light into interior spaces did not exist and we have relied on electric lighting and windows. Using parabolic mirrors, Anidolic daylighting system not only manipulates the daylight into the space, it increases the daylight levels within the room despite the weather conditions and climate. The Anidolic Ceiling and Anidolic Zenithal Opening captures incoming rays, maximising diffuse light and distributing it deeper into the space. The Solar Energy and Building Physics Laboratory building case study showcases the refurbishment of the southern façade with the Anidolic Ceiling system, achieving higher luminance and illuminance factors. The Anidolic Blinds are a façade system where the non-imaging optics prevent high solar rays but allow lower altitude diffuse light into the room. Solar Tubes or “Tubular Daylighting Devices,” an alternative means of redirecting daylight into a space, where it uses some of the same principles as the Anidolic daylighting systems. This system is shown in the Victoria University School of Architecture and Design case study, to make the rooms appear brighter and attracts students to the specified room. The overall report will verify the need to use optical systems for better daylighting performance and maximise energy efficiency while taking into account the comfortability of occupants.
1. Introduction
Awareness of the benefits of good daylighting has risen in recent years and the designs of many new buildings take daylighting into consideration. The problem is that the majority of our infrastructure is older than this trend and was not designed with daylighting as a top priority (Kleindienst, 2006). A need exists, therefore, to find an efficient means of improving the daylighting of existing buildings. Unfortunately, some of the most important elements in passive solar design-such
