The purpose of this study is to find the architectural characteristics of Verbena Heights, super high-rise complex housing, which has been most highly evaluated as a new town development model in Hong Kong, as a successful case of new housing type and sustainable design. The analyzed features of Verbena Heights are as follows; 1) Formation of various open spaces by a creative layout. 2) Enhancement of natural ventilation and daylighting by a linear plan instead of conventional cruciform plans. 3) Applications of integrated facade design for noise mitigation and for sunlight shading. 4) Adoption of energy-efficient devices, use of recyclable materials, and improvement of livability by a sustainable design process. These architectural characteristics provide the high-density high-rise housing with more efficient and comfortable environments for residents. And it is proved that the sustainable design can enhance the quality of dwelling environment.

A study on fire phenomena in a subway transit mass station has been carried out as a part of disaster prevention plan at the subway station. The ventilation facilities installed in both the platform and the trackway are designed to convert into a smoke exhaust system in emergency situation, creating an environment necessary for evacuation. 3 dimensional Numerical Simulations based on the CFD are carried out using a simulation tool, Fire Dynamic Simulator. Total of six different cases are made and performances are compared each other to find optimal vents operation to ensure safer environment for evacuation at the platform area considering the installation of platform screen door.

Interior space in most buildings is divided into several zones. The most important factors relating to the indoor air environment are temperature, airflow, humidity, and contaminant concentration. An integrated multizone model to predict these environmental factors simultaneously was developed. Also, a computer program for this model was written by the language of VISUAL BASIC. The proposed model was applied to a apartment with five rooms that had been tested by Chung. Comparison of predicted results by this study with measured results by Chung showed that their variations were within 14% for airflow rates, 1% for temperatures, 12% for humidities, and 5% for concentrations. It was seen that the opening operation schedule of building has a significant effect on the air moisture md contaminant removal. Thus, this model may be available for predicting the indoor air environment and may be contributed to design the ventilation plan for controling of indoor air quality.

The purpose of this study is to suggest of facilities improvement and plan at children shelters. To this purpose, the researcher visited and interviewed users of three children shelters. To achieve a concrete goal of the study, (1) property room size per admitted children, (2) space satisfaction as bedroom, living room in a establishment, (3) facilities satisfaction as corridor, sanitation fixture. furniture (4) environment satisfaction as electricity, cooling and heating, ventilation, (5) exterior satisfaction as building image, color, landscape was analysed by interviewing. Based on the results of the analysis, a improvement for children shelters was presented.

Recently the importance of the elderly facilities and the eco-friendly buildings is on the rise, due to the rapid increase of the aged population and the more and more serious global environment issues, respectively. Thus, the purpose of this study is to suggest an eco-environmental improvement plan which aims to improve the quality of life for the aged in planning nursing homes hereafter by reviewing the theory of the eco-friendly architectural concept and the same conceptual design, which become the issues of late, and thus analyzing the state of applying the eco-friendly design techniques to the municipal nursing homes located in Seoul. In this study its direction of the eco-friendly design required in nursing homes was established by reviewing the characteristics which the aged and nursing homes may have, and thus extracting the elements required for the quality of life for them. The theoretical studies showed that the environment-friendly natural elements necessary for the nursing houses are light, air and plants, from which three design elements are obtained: daylighting, natural ventilation and natural landscape. In conclusion, the eco-friendly nursing homes must be planned to improve the quality of life for the aged by recognizing that the eco-friendly architecture concept, emerged as a new paradigm, is the one to be put before all the considerations for those who are sensitive to the environment, and thus reviewing the characteristics found out from them.

The number of large scale greenhouses has recently been increasing to cope with mass consumption of agricultural product. Korean government announced a new development plan for constructing greenhouse complex in reclaimed lands for the purpose of improvement in exports and activation of domestic market of agricultural product. Wind environment in the reclaimed land is totally different from that of inland area, and it can give a strong influence on ventilation performance of naturally ventilated greenhouse facilities. In this study, internal airflow analysis of naturally ventilated greenhouse built on a reclaimed land was conducted using wind tunnel and PIV for validation research. Later, the PIV measured results will be used to improve the accuracy of 3 dimensional CFD simulation in the future. Wind profile at a reclaimed land was produced using ESDU program and it was applied to the wind tunnel. The calculated error was only 5% and 0.96 of correlation coefficient, implying that the computed profiles were designed properly. From the measured results, when external wind speed changed from $1m{\cdot}s^{-1}$ to $1.5m{\cdot}s^{-1}$, air velocities inside the greenhouse which PIV measured were also increased proportionately in case of both side vent open and side-roof vent open. Considering reduced ratio of air velocity inside the greenhouse, it was measured a minimum of 40% in case of side vent and 30% in case of side-roof vent compared with external wind speed from each vent type. From the quantitative and qualitative PIV analysis, the PIV measured results indicated that there were well ventilated and stagnant areas in the greenhouse according to external wind condition as well as ventilation design.

공동주택은 과학의 발전과 도시의 랜드마크적 상징성으로 점점 고층화 고밀화되어 가고, 입주민의 삶의 질 향상을 위해 각종 편의시설과 안전시설도 함께 발전되어 가고 있다. 그러나 통계자료에 의하면 공동주택은 사고 발생 대비 사상자가 높은 비중을 차지하고 있으며, 사상자의 주요 피해 원인은 심야 시간에 수면 상태에서 화재를 늦게 인지하여 연기에 의하여 많은 인명피해가 발생하고 있다. 공동주택에서 재실자의 연기피해를 최소화하기 위하여 실내에 별도의 배연 시설을 설치하는 것이 가장 최선의 방법이지만, 입주자의 경제적 부담을 줄이면서 현재 설치된 시설물을 활용하여 연기피해를 최소화하는 것이 공학적 입장에서 유용한 조치라고 판단된다. 검토 결과 전열교환환기방식과 주방공용배기방식을 선정하여 화재 시뮬레이션을 통하여 실증 여부를 검증하였다. 검증결과 피난허용시간(ASET)이 25층은 27 s, 35층은 30 s, 50층은 35 s가 향상되었다.

본 연구는 표준 개방한우사 설계도에서 제시된 처마의 길이보다 짧게 개방한우사의 처마가 시설되었을 때 지붕의 기울기와 동일하게 처마를 연장하는 것과 기둥 위치에서 수직으로 비가림시설을 하는 경우, 어느 우사가 우의 더위 스트레스 경감, 우방 바닥 건조, 비 들이침 및 환기효율에 더 유리한지를 규명하기 위하여 표준길이의 처마와 3종의 비가림 시설을 대상으로 computational fluid dynamics (CFD) 시뮬레이션기법을 이용하여 수행하였다. 여름철의 평균 풍속인 1.2 m/s에 근거하여 시뮬레이션을 한 결과, 여러 형태로 수직 비가림시설을 설치하는 것보다 표준 처마길이로 시공하는 것이 환기 및 풍속분포가 양호하였다. 따라서 수직으로 비가림시설을 하는 것보다는 축사 표준설계도에 제시된 처마 길이 정도까지 지붕의 기울기와 같게 처마를 연장하는 것이 유리하다.
