동계 및 하계 청천공 조건에서 베를린 지역의 사무실 공간에 적용된 오버행의 실내 주광조도 제어효과 (The Influence of Overhangs on the Control of Daylight Illuminance in Office Space in Berlin under Clear Sky in Winter and Summer)

초록

The variation of indoor daylight illuminance of a small office space in Berlin, Germany, was compared and analyzed according with the depth of the overhang in summer and winter solstice. Radiance was utilized for the analysis under various conditions for daylight and overhang depths. The depth of overhangs used for simulation were 0.55 m, 0.83 m, and 1.1 m. Results indicates that the daylights in summer solstice were effectively blocked by overhang. For the condition of winter solstice, the effects of overhang was weak due to lower incident angle of daylight from the sun. In Berlin, the overhang would not function effectively to control daylight in winter compared to summer. Linear regression models showed that the relationship between overhang depths and indoor daylight illuminacne were effective under a significance level of 0.1. The slope of regression model in summer solstice was steep compared to that for winter solstice due to the incident angle of sun for each day.
