3차원 천구에서의 외부일광조도 예측에 관한 연구
A Study on the Prediction of Exterior Daylight Illuminance under Three Dimensional Hemisphere
초록
A building and the solar are related to the privilege of solar benefit. To make step, it is required to build up an object, chase the position of object and the solar, find the shadow occurrence. On the subject of direct illuminance, an intensive emission of irradiation is proposed to directly project to the benefit area. Simultaneously on the indirect illuminance, the integration of a finite element incident to the benefit area can be multiplied by the hemisphere luminance. A caution should be paid to eliminate the occupation area of the object around on the hemispherical sky, which can help run more accurate prediction.
