- Abstract
- For accurate daylight simulation, accurate exterior illuminance is necessary. But, Korea Meteorological Agency provides only the solar irradiance data. Thus, there is a need for the research on luminous efficacy. In this study, global horizontal irradiance, diffuse horizontal irradiance, global horizontal illuminance, and diffuse horizontal illuminance were measured to calculate the luminous efficacy in SEOUL. And, we evaluated the applicability of the Perez`s model by comparing the measured data and calculated data. As a result, measured global luminous efficacy is 126(110～129)lm/W and diffuse luminous efficacy is 127(115～133)lm/W in Seoul. Perez`s model was relatively accurate with 5% difference in the diffuse luminous efficacy. But, it can be predicted about 15% lower in the global luminous efficacy.
