- Sustainable core daylighting is expected to provide comfortable and healthy daylight in dense urban areas. One system, an anidolic daylighting system is a promising solution, however, it is still not widespread because of several complications. This paper presents an application of an affordable anidolic daylighting system on a tropical urban house designed with a simple edge-ray approach. This approach has created a parabolic collector for east-facing (azimuth 85_) anidolic daylighting system to improve the daylighting level of a room with high external obstruction. Simulation results and short-term monitoring before and after the construction have indicated successful application of an anidolic daylighting system for improving daylighting performance, especially before 13:00, without increasing indoor air temperature. The results have shown a strong hourly illuminance profile. To improve the indoor illuminance after 13:00 and the hourly illuminance profile, an east-facing anidolic daylighting system collector can be combined with a west-facing collector.
