광화이버 및 Fresnel lens 적용 집광식 자연채광 시스템의 이용을 통한 조명에너지의 절감 = Electric Lighting Energy Saving Through the Use of A Fresnel Lens Based Fiber-optic Solar Lighting System - Simulation and Measurements -

다국어 초록 (Multilingual Abstract)

This paper deals with the effectiveness of a fiber optic solar lighting system that uses a Fresnel lens mounted on a two-axis solar tracker. A series of comparative analyses were made concerning its performance as compared to fluorescent lighting by using a simulation model based on ECOTECT and RADIANCE as well as referring to actual data. ECOTECT was used to model the test room (space) while RADIANCE was used for its indoor lighting conditions (environment). It was found that the average indoor light levels of fluorescent lighting fully satisfy the KS standard (KS A 3011, general office, class [G]: 300-400-600 lux) whereas those of the solar lighting with light diffusers depends on the occlusion factor of roller shades installed on the south window.
