| 요약2 | Recently many buildings have been built with glass curtain walls. Those buildings located in urban areas frequently cause discomfort and/or disability glares for adjacent building occupants and nearby automobile drivers. This study was performed to provide information for designing external shades much as vertical fins and eggcrates to prevent specular sunlight reflections off the glass curtain walls. In this study, the geometry of the external shades were expressed as Fin Index(FI) and Eggcrate Index(EI). Fin Index is the ratio of the fin length to the width between fins. The Eggcrate Index is ratio of length to width and height. Then, RADIANCE program was used to evaluate the effectiveness of the external Shades in protecting the sunlight reflections in terms of glare occurrence and the duration of the glare. The results showed that the vertical fins effectively prevented glare from occuring when the FIs were 1.2 for 90° fins and 1.0 for 45° fins. On the other hand, no glare were observed when the buildings were treated with eggcrate shades of 1.2 EI. |
