External fire spread has the potential to breach vertical compartmentation and violate the fire safety strategy of a building. The traditional design solution to this has been the use of non-combustible materials and spandrel panels but recent audits show that combustible materials are widespread and included in highly complex systems. Furthermore, most jurisdictions no longer require detailing of spandrel panels under many different circumstances. These buildings require rapid investigation using rational scientific methods to be able to adequately classify the fire risk. In this work, we use an extensive experimental campaign of material-scale data to explore the critical parameters driving upward flame spread. Two criteria are outlined using two different approaches. The first evaluates the time to ignition and the time to burnout to assess the ability for a fire to spread, and can be easily determined using traditional means. The second evaluates the preheated flame length as the critical parameter driving flame spread. A wide range of cladding materials are ranked according to these criteria to show their potential propensity to flame spread. From this, designers can use conservative approaches to perform fire risk assessments for buildings with combustible materials or can be used to aid decision-making. Precise estimates of flame spread rates within complex façade systems are not achievable with the current level of knowledge and will require a substantial amount of work to make progress.

This study examines the site and erection of the Government Complex Seoul which was a project attempted to assemble dispersed government buildings in a certain place. The study focuses on the fact that the project is situated between the 1960s' making of capital Seoul and Seoul urban planning, and the way how the project achieved symbolism in capital Seoul. The project, one of the 1960s' Major Government Buildings, led both plan of capital Seoul and transforming city Seoul. The 1960s' Major Government Building Plan had identical drive with the 1950's Major Government Building Plan, however the 1960s' had additional layer: Seoul urban planning. After restoration of the Capital building, Sejongro the capital street was planned to the site arranging government offices. The Government Complex Seoul was set to be a modern building on a site with historical context according to the plan. Because of the site, the Government Complex Seoul was constructed in aware of other buildings that represented a competitive high-rise atmosphere in the late 1960s, including the Capital building nearby. PAE International's plan was completed through a series of design modification, and it boasted a vertical aspect, unlike the horizontal-looking plan that was already won after the design competition. The Government Complex Seoul tried to acquire the symbolism in the central space of the capital Seoul and high-rised city Seoul. "The new construction method" was a requirement to achieve the height.

One of the most important elements in creating the pleasant residential environment is the wind. For the pleasant residential environment, it is important that the air pollutants are not stagnant but appropriately and swiftly diffused and removed by winds. Especially, the river becomes a main route of wind in the urban core. So, it is necessary to secure the space to circulate the sufficient cool air to this area. But, recently many high-rise apartment complexes have been built along the rivers that have the fine view and pleasant environment. As a result, the cool and fresh air coming from mountains hardly diffuses into the urban core but just flows along the river. Considering the facts above, this study selected types of building layout and kind of land cover as complex or architectural design factors that have an influence on wind environment. Based on the factors, it analyzed change in wind environment according to apartment complex development aiming at the Sinchun area which is Daegu Metropolitan City's main wind corridor. Therefore, when apartment complex development is planned in the future, it can offer basic data for establishing plans for more pleasant complexes. As a result of the analysis, it was shown that the layout type of housing and the building height plan in consideration of wind corridor around the river were pretty effective in increasing the wind speed and circulating the air in the apartment complex. Therefore, if wind corridor is considered when apartment complex development is planed in the future, this study can offer useful information contributing to improve comfort in residential environment in the level of complex building as well as city planning.

최근 도시 미관이 중요시 되면서 동일 아파트 건설단지 내에서 저층과 고층 아파트가 혼합배치되는 경우가 많아지고 있다. A공사에서 발주한 아파트 사업지구 중 고층 동들과 저층 동들 간의 층수 차가 4층 이상인 지구가 약 33%인 것으로 조사되었다. 일반적으로 아파트 공사의 공기는 단지 내최고층 동을 기준으로 산정한다. 이로 인해 전체 사업지구의 공사기간이 길어지고, 길어진 공기는 해당사업의 사업성에 나쁜 영향을 미친다. 그러므로 동일 단지 내 저층 고층 아파트 동들이 혼합 배치된 사업지구(이하 "혼합사업지구"라 한다)의 사업성 제고를 위해 일부 고층동 아파트의 골조공기를 단축해야 할 것이다. 그러나 혼합사업지구의 다양한 유형으로 인해 어떤 경우에는 공기단축이 사업성을 더 나쁘게 만들 수 있다. 따라서 본 연구에서는 다양한 유형을 갖고 있는 혼합사업지구의 골조공기 단축 여부를 판단할 수 있는 자료제공을 위해 혼합사업지구의 일부 고층동에 대한 골조공기 단축이 건설사업비에 미치는 영향을 분석하여 그 결과를 제시하였다.

This study tried to prove why a low-rise residential block is more vitalized than in a superblock consisted of an apartment housing complex. To do this, two adjacent superblocks in Yeoksam 2-dong were selected as a case study among superblocks of residential area in Gangnam, Seoul. It adopted the concept of 'complexity', 'Osmosis', 'Vitality' and 'Permeability' for evaluation indexes to measure street vitality. As a result, four indexes were clearly higher in low-density residential superblocks than apartment housing complex superblocks. First, the superblocks for apartment housing complexes showed a lower 'complexity' because large-scale parcels for an apartment housing complex reduces a possibility for various land uses. Second, smaller blocks improved "osmosis" compared to larger blocks, and the larger the block, the less likely it is that buildings and streets penetrate activity. Third, as the apartment complex block became larger, the number of accesses decreased. Thus, it did not provide vitality to the streets. Fourth, high permeability was shown in the low-density superblocks, while that of the superblock consisted of apartment housing complexes was very low because the entrance of the complexes entrance is closed to the public. The results of this study demonstrated that an apartment housing complex may hamper street vitality and deteriorate the quality of urban environments.

In urban area, inversion layer prevents air pollutants from being dispersed. To determine nocturnal inversion characteristics at SookMyung Girls' High School near high-rise residential commercial complex buildings in Seoul, air temperature and humidity data were observed at 10minute interval from December 1st, 2007 to May 2nd, 2008. Temperature-Humidity (T-H) sensors were installed at SMG (SookMyung_Ground) and SMR (SookMyung_Roof), and then these two data were compared, analyzed and examined to illustrate air temperature differences of SMG and SMR. After the analysis, the maximum nocturnal inversion was observed by $3.3^{\circ}C$ at 18:10 on December 26th 2007, at that time the weather condition was clear and weak wind. Nocturnal inversions began 2-3 hours before sunset and it reached maximum inversion just after sunset and continued through nighttime until sunrise or 1-2 hours after sunrise. In terms of seasonal variation nocturnal inversions occurred dominantly in March and April rather than winter season.

Role of architecture should not be limited to function of providing an inhabitable space but also include urban and social role of its impact to the public and surrounding area. Role of landmark building should be further expanded beyond and landmark building speaks out its aesthetics with mass form and/or with its appearance of façade. With study of this project, idea of landmark building is shifted from vertical extrusion of the land to horizontal extrusion of large space from the face of building. It is a double extrusion creating large assembly space up in the air linking surrounding masses.

Advances in the technology of computational design are giving architects and engineers the opportunity to analyze buildings with complex geometries. This study explores the optimization and automation process using the parametric design method, and uses digital tools to achieve surface representation and panelization for curved shaped office buildings. In this paper, we propose parametric algorithms of dimensional and geometric constraints using the Knowledge-ware scripts embedded in Gehry Technologies' Digital Project. The knowledge-based design methods proposed in this study can be used to systemize the knowledge possessed by experts in the form of data. Such knowledge is required to promote collaboration between designers and engineers in the process of CAD/CAE/CAM. The aim of this study is to integrate the process into design, which establishes an integrated process. This integration enables two-way feedback between design and construction data by combining the methods used in designing, engineering, and construction.
