This study aims to evaluate of POF daylighting system performance. In this study, POF daylighting system has developed and applied to KIER test buildings. POF daylighting system consists of three parts: light collector, light transmitter and light diffuser. The light collector includes a circular Fresnel lens which gathering and focusing solar direct illuminance by sun tracking. The light transmitter contains the POF(Plastic optical fiber) cable which has light transmission loss of 4.5% per meter. The light diffuser has about 80% diffuser efficiency. At the results of POF system performance evaluation, theoretical POF system efficiency was 41.9% and actual POF system efficiency at the KIER test building was 38.2%. Moreover, system efficiency distribution almost uniformed at the actual test, except 16:00. |
