The purpose of this study is to analyze daylight distribution and characteristics of light on the Korean traditional paper and to investigate a possibility as the shading systems. First of all, daylight distribution through the Korean traditional paper windows and doors of the Traditional House is analyzed at Genjaegotaek of the Asan Oeam Traditional Village. After making a model, the characteristics of light on the Korean traditional paper and Roller Shade fabric are analyzed Korean traditional paper has a good efficiency to diffuse the light and is less glare than Roller Shade fabric. In the present office buildings and apartmant houses, daylight characteristics of the Korean traditional paper windows and doors could be used as preliminary data to develop a window system which makes greatest performance of daylight.

국내 에너지 소비량의 21.6%가 건물 분야에 소비되고 있다. 창호는 벽체에 비해 8~10배 이상 낮은 단열 특성을 가지기 때문에 열 손실량이 크다. 유리는 창호를 이루는 요소 중 가장 큰 면적을 차지하고 있으며, 창호의 단열성능을 2배로 향상시키면 30% 이상 건물의 에너지 절감 효과를 가질 수 있다. 창호의 단열 성능을 향상시키기 위해서 Low-e(emissivity) 기술 연구가 진행 중이다. 이번 실험에서는 RF 마그네트론 스퍼터링 시스템을 사용하여 XG 유리기판 위에 ZnO박막을 증착하고, evaporator 장비를 사용하여 metal층인 Ag를 증착하였다. 그리고 다시 한번 ZnO박막을 증착하였다. Low-e 연구에 활용할 수 있는지를 확인하기 위해 XRD, AFM, 투과도를 측정하였다. ZnO박막의 증착 조건은 초기압력 $3.0{\times}10^{-6}$ Torr, 공정압력 $2.0{\times}10^{-2}$ Torr, RF파워 30 W, Ar gas는 50 sccm, 증착온도는 상온으로 하였다. Metal층인 Ag를 증착하기 위해 evaporator의 증착 조건은 Rotate rate 2 rpm, voltage 0.3V, 공정압력 $5.0{\times}10^{-6}$ Torr이며, 변수로 Ag두께를 3,5,7,9,11,13,15 nm로 하였다. AFM 측정결과 Ag두께가 증가할수록 RMS roughness값이 높아졌으며, 최소 0.71 nm의 거칠기를 가지는 것을 확인하였다. XRD분석결과 37도 부근의 피크가 발생하여 ZnO 박막이 결정질 구조임을 확인할 수 있었다. 그리고 UV-Visible-NIR 분광 광도계를 이용하여 광학적 투과를 측정한 결과 Ag두께가 13 nm일 때 가시광 영역의 투과도가 최대 75%, 적외선 영역의 투과도가 최소 28%로 좋은 차단 특성을 가지는 것을 확인하였다. 위 결과들로 ZnO 박막이 Low-e 기술에 활용될 수 있음을 확인하였다.

In a typical living space, windows are directly exposed to the external noise environment. The best way to reduce outside noise is to block it from the outside, not the inside. Exterior blinds for blocking sunlight are commercialized in various ways. However, it has not yet been actively utilized in Korea. In the previous study, an experiment was conducted in an accredited laboratory to verify the sound insulation performance of an external motorized blind manufactured for shading. And it was verified that there is a sound insulation performance of 6 dBA compared to the reduction performance of a general window. In this study, we tried to confirm the reduction performance by applying the sound insulation performance of external electric blinds to windows in actual living spaces. In addition, an improvement plan was sought to increase the effective noise reduction performance. As a result of the measurement, the reduction performance of the external motorized blind itself was insufficient at the level of 1 dBA to 3 dBA. However, additional reduction performance of the 2 dBA level was confirmed by filling the gap between the blind slits.

In study to investigate losing energy of building in window, we analyze the heating loss parts in the material of structure throughout modeling of window system. Also, by making modeling in the building using simulation, we investigate the heating load variation of building in window. According to the type of windows and the material of structure, we analyze the energy variation of building and a temperature variation.

본 연구에서는 건축외장용 접착제의 발연특성을 알아보기 위해 접착제를 용도별로 구분하여 연기밀도시험기를 이용해 최대연기밀도와 초기발생연기밀도를 알아보았다. 실험 결과 창호전용 접착제가 586초에 509.64로 가장 많은 연기밀도를 발생하였으며, 석재용 275.63, 목공용 232.25의 순으로 많은 양의 연기가 발생하였고, 타일용 18.65, 스티로폼용 6.44로 최대연기밀도를 나타내었다. 창호전용과 스티로폼용의 경우 최대연기밀도를 나타낸 시간은 비슷한 범위에 나타났으나 연기밀도 값은 스티로폼용에 비해 창호전용 접착제가 80배 가까이 연기가 더 발생하는 것을 알 수 있었다.

There is something valuable in Korean traditional architecture that does not change even after more than a number of years. Each design element of traditional houses has its own role to embody natural, healthy, and environment-friendly architectural planning. With traditional already-built examples located in the northern area of Gyeongbuk province, this study attempts to untangle some of the daylighting control issues in opening design. By looking at more than just photometric materials, at some threshold level, the whole of daylighting control characteristics of their openings is being surveyed from the viewpoint of geometric relationship between their roof structures and windows. As a glazing material, in addition, Korean traditional window covering paper, Changhoji, is evaluated for its transmittal performance under artificial and real skies as well.
