아트리움 건물의 중정 내부 발코니의 채광 특성에 관한 연구

초록

Designers who predict daylighting performance in atrium spaces usually assume that the atrium space is empty. In commercial, industrial and institutional atrium buildings, light attenuation caused by interior obstructions can affect working efficiency and in extreme cases, safety. In the initial stage of the daylighting design process, the impact and light attenuation caused by major interior obstructions should be considered on the basis of other critical design factors to improve the accuracy of prediction of whether the light level in atrium spaces is adequate for typical general tasks and plant growth. The objective of this research is to develop insights and design guidance regarding the critical daylighting performance factors by evaluating the relative impact of various interior balcony configurations on illumination level and its distribution with different atrium geometries and wall reflectances. For these, parametric measurements of illumination level with a scale model of four-sided atrium building have been conducted under overcast sky condition within the sky simulator at a Texas University. This research represents the atrium performance results in terms of Daylight Factor, well index, balcony well index, the configuration of interior balcony, and interior reflectance and the results are compared with basecase atria without interior balcony.
