Natural ventilation has proven to be an effective passive strategy in improving energy efficiency and providing healthy environments. However, such a strategy has not been commonly adopted to tall office buildings that traditionally rely on single-skin façades (SSFs), due to the high wind pressure that creates excessive air velocities and occupant discomfort at upper floors. Double-skin façades (DSFs) can provide an opportunity to facilitate natural ventilation in tall office buildings, as the fundamental components such as the additional skin and openings create a buffer to regulate the direct impact of wind pressure and the airflow around the buildings. This study investigates the impact of modified multi-story type DSFs on indoor airflow in a 60-story, 780-foot (238 m) naturally ventilated tall office building under isothermal conditions. Thus, the performance of wind effect related components was assessed based on the criteria (e.g., air velocity and airflow distribution), particularly with respect to opening size. Computational fluid dynamics (CFD) was utilized to simulate outdoor airflow around the tall office building, and indoor airflow at multiple heights in case of various DSF opening configurations. The simulation results indicate that the outer skin opening is the more influential parameter than the inner skin opening on the indoor airflow behavior. On the other hand, the variations of inner skin opening size help improve the indoor airflow with respect to the desired air velocity and airflow distribution. Despite some vortexes observed in the indoor spaces, cross ventilation can occur as positive pressure on the windward side and negative pressure on the other sides generate productive pressure differential. The results also demonstrate that DSFs with smaller openings suitably reduce not only the impact of wind pressure, but also the concentration of high air velocity near the windows on the windward side, compared to SSFs. Further insight on indoor airflow behaviors depending on DSF opening configurations leads to a better understanding of the DSF design strategies for effective natural ventilation in tall office buildings.

Elderly welfare housing refers to a residential facility with diverse medical and welfare services for cohabitation of elderly. Especially, community shared spaces in the elderly welfare housing plays an important role as a place for community and leisure activities that enhance vitality of elderly life. The purpose of this study was to investigate types, planning characteristics and actual utilization of community shared spaces in for-profit elderly welfare housing. Eight for-profit elderly welfare housing facilities in Seoul and Gyeonggi province were selected for this study and categorized into small-, medium- and large-scale facilities based on the number of housing units. Community shared spaces in the elderly welfare housing were classified into six space types: social space, education space, exercise space, medical space, convenience space and leisure space. Findings are as follows. Small-scale elderly welfare housing facilities with less than 100 housing units had fitness centers, clinics, restaurants, convenience stores and hobby rooms which were required by law. All community shared spaces were planned on a single level. Fitness centers was found the most frequently used while the other spaces were not used very frequently. Medium-scale facilities with 100 to 299 housing units had multi-purpose halls, libraries, swimming pools, indoor and/or outdoor driving ranges, physical therapy centers, saunas, karaokes and so on. Most community shared spaces were found frequently used. Large-scale facilities with 300 or more housing units had religion rooms, community halls, hair salons, pharmacies, etc. In most facilities, community shared spaces were planned in distributed locations.

The ultimate goal of this research is to establish the movement rights of people with physical disabilities. To achieve this goal, the authors have investigated the regulation and restrictions of physical facilities to guarantee the movement rights and investigated how well these facilities were constructed. The authors then have analyzed and compared the results. The purposes of this research are as follows. First, the authors investigated and analyzed the present conditions of selected public facilities to propose improvement measures for the disabled, pregnant and seniors so that they could actively participate in cultural activities as normal people do. Second, the designs resulting from this research are provided so as to be helpful to disabled people in everyday life, which is different from previously conducted research. Third, the authors have selected facilities with outdoor areas to differentiate the results from those reported recently through research conducted on indoor buildings. The final step of this research is to provide basic design data on outdoor areas to establish true movement rights for the disabled. According to these research findings, the shortest moving distance cannot be guaranteed only by establishing facilities that follow the Article 3 law about guarantee of convenience improvement for the disabled. If the movement path is not regulated, the facility standards may not exist in one part and the part itself may become obscured and the distance could become longer than necessary. Accordingly, for real movement rights the movement path should be guaranteed not to be violated by other obstacles. The results of this study offer convenience when moving within the outdoor space of cultural facilities by providing direct information for the disabled. The value of this study is that it is the first study on movement rights and movement paths for people with physical disabilities.

입체녹화가 도시환경을 향상시키는 효과가 있는 것으로 알려지면서 친환경 건축물의 새로운 대안으로 부각되고 국내적용에 대한 다양한 연구가 필요해지고 있다. 본 연구의 목적은 국내외 건축물 준공사례를 대상으로 건축물 내 외부에 반영되고 있는 입체녹화의 공간특성을 조사하고 구성체계 및 디자인요소를 분석하여 친환경구성을 위한 부문별 디자인 적용요소의 발전방향을 제시하는 데 있다. 분석결과, 입체녹화는 건축물 내 다양한 외부공간을 증가시키기 위하여 대형화하는 고밀도 개발형태를 보이며 초기에는 전시, 교육 등 공공시설이 많았으나 최근에는 공동주택 사례가 증가하고 있다. 공동주거 Unit에 다양한 근접공간을 도입하고 사적 공간에서 독립적인 녹화공간을 제시하는 등 거주자의 선호조건에 따라 선택적으로 근접공간을 이용하도록 계획하는 방법은 일률적인 국내 공동주거의 디자인을 지양하고 거주자의 다양한 행위를 유도할 수 있다. 새로운 공간분위기와 다양한 옥외공간으로 인한 커뮤니티 장소들은 사회적 상호 작용을 통해 공동주거의 생활패턴을 변화시키고 새로운 마을공동체를 조성하는 방법이 될 것으로 판단된다. 또한 대지의 환경특성을 적극적으로 반영하고 건축물 형태에 자연지형과 경사로를 이용하는 경향을 뚜렷이 보이고 있어 외부공간 환경조성 디자인요소에 대한 후속 연구도 필요하다.

To effectively use Building Information Modelling (BIM) dealing with semantic information including the entities of building components, the information about building components should be standardized. Like standardized modern buildings. in the past, Korean traditional houses were built according to strict procedures and formats. Therefore, if the Korean traditional house are modelled by using BIM,. not only the Korean traditional house of good quality will be built quickly and cheaply, but also spaces in the existing Korean traditional house will be easily analyzed. However, when analyzing spaces of the Korean traditional house using Space Syntax, some problems are caused in dividing outdoor space such as yard with unclear boundaries, unlike indoor space with clear boundaries surrounded by walls. These comes from the fact that researchers have subjectively divided a space in the house into convex spaces as units for Space Syntax analysis. Therefore, this study aims to develop an objective and rational spatial subdivision technique for Space Syntax analysis of a Korean traditional house modelled by using BIM. We could objectively and reasonably divide a Korean traditional house space into convex spaces by recognizing the building components in the house modelled in the form of Industry Foundation Classes(IFC). Depending on the connection of convex spaces allocated in the spatial subdivision technique, j-graph in Space Syntax could be drawn and the measurements of spatial configurations could be determinded. Through the developed technique, the social properties including the cultural and philosophical aspects of Korean people was identified by measuring the spatial configurations of Korean traditional house. The developed technique will serve as useful means to help architects to find an appropriate purpose of each space for sustainable architecture on the basis of the spatial and social relationships in buildings or urban systems.

This study aimed to analyze health promotion villages from the perspective of therapeutic architecture, and to provide basic information for planning relevant health facilities. On the basis of a review of previous literature, the characteristics of therapeutic architecture were classified into eight categories: safety, comfort, sociality, autonomy, openness, diversity, privacy, and natural environment. Field study and observation were performed in four health promotion villages that conduct programs for lifestyle improvement, physical fitness, and treatment; these villages were also considered to have a healthy residential environment. The researcher and three assistants visited the facilities and checked utilization of space through interviews with the staff and guided tours. Basic information about the subject facilities, such as the purpose of establishment, was gathered from websites before visits. Two of the villages examined in this study had a traditional Korean wooden structure, while the other two were reinforced concrete and masonry block structures. All the facilities emphasized the use of environmentally friendly material and harmony with nature. Each site was divided into the following areas: office, residence, health/treatment, public/rest, and outdoor. The safety standards of the healing architecture were not completely satisfactory at all facilities. In particular, it was found that they lacked adequate universal design equipment. However, the healing characteristics of autonomy and diversity were strong. With regard to autonomy, the facilities allowed visitors to select indoor-outdoor moving lines and the use of front- and backyards constructed on slopes. In addition, they were equipped with many entries, staircases, void, terraces, and crossroads. The architecture was aesthetically designed using feng shui symbolism, and visitors found the scenes depicted in various spaces in the villages to be stimulating. Besides, the facilities were constructed using natural materials, had a natural indoor environment, and provided a sense of spaciousness and flexibility.
