  • 낮시간에 창이 있는 장소에서는 주광의 입사로 제법 높은 조도가 얻어지면 그의 정도는 기상조건이나 건물 및 창의 구조, 실내조건 등에 따라서도 변화한다. 따라서 변화하는 외광의 밝음을 실내에 설치된 주광센서로 검지하여 창가에 있는 일정범위내의 조명기구를 자동적으로 점멸 제어하여 전력절감을 도모하는 것이다.

  • Most of domestic building generally don't have fixed shading devices considering of appearance and aesthetic issues. In this study is suggested that tilt window simultaneously has a role of shading and blocking solar radiation. The tilt window thermal performance is investigated by relation ship between inclination and heating cooling road. As comparing vertical window with $5^{\circ}$ and $7^{\circ}$ of tilt window respectively, the heating load is increased by 3.6% and cooling load is reduced by 8.1% on $5^{\circ}$ tilt window and the heating load is increased by 5.3% and cooling load is reduced by 11.5% on $5^{\circ}$ tilt window. Especially, the total load of alternative tilt window is showed the reduction rate 2.6% and3.6% compared of vertical window. Therefore, the tilt window is possible to role of shading of solar radiation and reduction of heating and cooling load.
