Autoclaved Lightweight Concrete(ALC) features such as a high performance insulation, the fire resistance, the advantage of easy handing construction, and lightweight panels applied the curtain wall system. ALC materials are certified as non-toxic environmental and eco-friendly productions. But ALC external panels mixed with blast furnace slag pounder and silica fume have to be coated with a stucco compound or plaster because of resisting the ambient environment. This study is that mixing tests to evaluate a performance analysis of exterior paints to be make-up pigments(organic or inorganic) coated with panel surface. Testing compared by KS F 2476; flow test, KS F 2426; compression strength test, KS F 2762; bond strength test. In results, the case of the inorganic binder, ratio of alumina cement : anhydrite is 90:10 to 80:20 at the highest level of intensity. In the case of the organic binder, adhesive strength rating at surface of ALC, the pullout strength is below 0.5 $N/mm^2$ but the normal concrete is over 2.0$N/mm^2$. A contents ratio of EVA resin is more than 3% and then bond strength is effectively.

우주발사체의 2단용 엔진으로 10톤급 케로신 재생 냉각 방식의 액체로켓엔진에 대한 보조 냉각 기구로서, 막냉각을 고려한 냉각특성에 대한 해석적 연구를 수행하였다. 연소기내에서 연소가스의 유동이 축방향으로 층류화되어 있다는 개념하에, 엔진 단면을 서로 독립적인 중심부와 외곽부로 나누며, 외곽부에는 여분의 연료를 분무시킴으로써 연소가스 온도를 낮추어 냉각채널로 전달되는 열유속량과 벽면 온도를 감소시킬 수 있었으며, 엔진의 열적 안정성을 향상시킬 수 있었다.

The Purpose of this study was to investigate the exterior materials of super high-rise housing more than 30 stories which were built in New York City between 1924 and 2004. The result of examining 153 buildings was as follows; Exterior materials of super high-rise housing which were used bricks, of the salt-glazed bricks, terra-cotta and ceramic tiles, jumbo bricks and bricks were preferred among them. The colour of bricks was yellow, yellow ochre, clear brown, brown, dark brown, orange, vermilion and red. Exterior materials of super high-rise hotel and hotel apartment were bricks and ceramic tiles in the early days but stones, curtain wall and glass(green glass, green-tinted glass, brown-tinted glass, black glass) after 1980s. The main colour of buildings extended gray, green, blue-tinted brown-tinted and black.

Recently, the condensation of walls often occurring in domestic high-rise apartment buildings is an important problem. The main purpose of this study is to develop the prediction method for the surface condensation on curtain wall in high-rise apartment buildings. Therefore, in this study, we first analyzed exterior climate factors through the analysis of the Seoul climate data and predicted the change of indoor temperature by using Apache program to find the cause of the condensation state and to prevent condensation. Also, according to this result, exterior climate factors and interior factors, which caused the condensation, was examined. The thermal performance of the curtain wall and the range of potential condensation were analyzed to focus on high-rise apartment buildings through computer simulation programs. The results are as $follows;^1$) The frame edge of curtain wall has a higher U-value than in the center by $30%^2$) Because of stack effect, the rooms on the higher floor have a lower external ventilation rate resulting to a higher relative humidity3) Installing a ventilation system($20m^3$/h. person) makes it possible to have a higher external ventilation rate, resulting to a lower relative humidity.

본 연구는 공동주택의 화재 및 화재확산에 의한 피해의 예방과 대응마련을 위해 실내화재 조건에 대한 정확한 데이터 확보를 목적으로 실물화재실험을 재현하였다. 실험조건으로 개구부 크기를 다르게 하여 외벽 수열온도를 측정 및 분석하였으며, 다음과 같은 결과를 도출하였다. 개구부 크기를 2,000mm, 1,600mm, 1,400mm로 실험하였을 때, 플래시오버는 각각 630초, 505초, 510초에서 일어났으며, 총 가열시간은 개구부 크기에 따라 815초, 713초, 721초로 나타났다. 개구부 크기에 의한 외벽 최고 수열온도는 2,000mm에서 282.4℃, 1,600mm에서 382.9℃, 1,400mm에서 423.8℃로 나타나 개구부의 크기가 작아질수록 화재확산에 의한 외벽의 수열온도는 높아지는 것으로 나타났다.

본 연구는 매년 수만 건 발생되는 화재에서 화재확산에 의한 피해 예방과 대응 마련을 위해 공동주택 및 일반건물의 내부화재를 실물화재실험을 통해 재현하였다. 또한, 개구부 크기와 차양길이 조건을 달리하고 이에 따른 외벽온도 분포를 분석하여 화재확산방지 기초자료를 제공하고자 하였다. 실험결과, 차양을 설치하지 않았을 때 최고온도는 약 380℃ 이상으로 나타났다. 차양을 설치하지 않은 최고온도를 기준으로 차양길이가 150mm 일 때, 동일한 측정점에서 약 90℃가량 낮아졌으며, 300mm에서 약 150℃ 이상, 450mm에서 175℃ 이상 온도가 낮아졌으며, 차양길이 600mm 일 때, 최고온도 차는 약 180℃ 이상 낮아지는 것으로 나타나 개구부 상부의 차양 설치가 외벽의 수직화재 확산에 의한 화염온도를 낮추는데 효과가 있는 것으로 판단된다.

According to the survey results of the Ministry of Land, Transport and Maritime Affairs in the end of December 2011, the residential buildings was reported as 67.3% of 4,529,464 buildings. Reflected in the national energy policy, the residential building is expected that greater energy savings. To have realized the Passive House Project used the Autoclaved Lightweight Concrete(ALC) material on exterior wall, we take advantage of a very large energy savings. Therefore, this study investigate the patent documents of three major companies, SUMITOMO, CLION, ASAHI KASEI, in Japan. and analyze technical flow and benchmarking patent. As a result, the Sliding method or the Rocking method of ALC panels how to install is to be superior to high-performance drift and safety by a earthquake. And the embedded anchor in panel needs to improve the shape and the strength of bearing. Thus installation technology of the ALC exterior wall investigated in japanese patent documents is expected to the fastening units and anchors.

The various attempts is made to solve the energy and environment problems. In addition, people interested in their life quality want the more eco-friendly living space. So we suggested that the earth-sheltered house could be one of the eco-friendly and low energy consuming houses to meet the social interest. And we also made data for design of the earth-sheltered house to be applicable to climate of Korea. In this study, a simulation was performed to estimate a boundary temperature according to earth sheltering thickness at the earth-sheltered part(exterior wall) in the case of earth sheltering on the plane ground not using a sloped site. And we analyzed the reduction of a thermal load by using this boundary temperature. We also compared a case of earth sheltering at the vertical wall with a case of earth sheltering at the roof to know the thermal reduction effect of a case of earth sheltering at the vertical wall.

This study is about finding out characteristic of recognition individual housing in seaside of Donghae. To accomplish this purpose, we survey the 150 houses related to the landscape. Thus the major analysis is to take basic data, such as image(modern, western, traditional, etc) about exterior form of housing corresponding to the landscape. The result summarized as follows First, the elements for the characteristic of recognition were exterior material finish, exterior color, roof type, roof material finish, window size, roof slope, area of wall vs roof. Second, the image of traditional housing was very insufficient to plan landscape of housing with design elements. This research suggests that landscape housing of future is to be environmental landscape design and the proper design is to be various considering not only user's preference but also control of landscape.
