This study has the purpose a remodeling plan of apartment complexes in residential areas. Based on the analysis on characteristics of circumstance surrounding it and economic gains for the residents who live in the apartments, this study suggests a concrete model to accomplish the purpose. The apartment in Nowon-gu was studied and some apartments which have same characteristics with the target of remodeling plan were interviewed and answered the questionnaire. To grasp the functions required and planning factors of apartment's remodeling, the questionnaire focused on the residents' request in each levels of their own entire hosing complex, just a building in the hosing complex area, and their own household. The conclusion is, (1) The major problems of common apartment complexes were serious aging, insufficient everyday life facilities and high rate of the residents' dissatisfaction. (2) The study suggests remodeling plans of an apartment complexes in each levels of their own entire hosing complex, just a building in the hosing complex area, and their own household, such as, underground parking area, tree-planting of first and top areas, improvement of a housing floor plan, a view of the front side, and so on.

This paper investigated the sound characteristics in an apartment complex. The field measurement was conducted in order to examine the acoustical characteristics of the apartment complex in situ. As a result, it shows that there are around 3 sec. reverberation time and the additional sound reinforcements at the area of high height due to the surrounded buildings. Thus, 1:50 Scale model measurement and Raynoise computer simulation were carried out with insertion of the parapet and the canopy on the balcony. In case of a single building, the parapet was effective to reduce noise level at low floor levels, and the canopy was effective to reduce noise level at high floor levels. But it also shows that both the parapet and the canopy were not effective to reduce noise level at middle floor levels. In case of an apartment complex, the canopy was less effective to reduce noise level at each floor in comparison with case of the single building.

In Alvar Aalto's designs, important factors of complex building designs including Wolfsburg cultural center are that they insinuate how to develop each architectural type and how to combine them in a building. The humane and physical background studies, and wholistic and systematic approaches are adopted to fulfill research purposes. Comparison with other buildings are necessary to reveal true meaning of this building. The result of analysis show characteristics of Wolfsburg cultural center as follows; hybrid composition of mass and elevation, spatial effect using level difference and light, massing variation of roof, and creating space for various activities. Wolfsburg cultural center designed in late 1950s has greatly affected Aalto's later works through various architectural experiments because it is the first cultural complex project that combined various architectural types. Especially library in the cultural center has shown transitional characteristics to famous fan-type libraries of 1960s while maintained features about Viipuri library. Wolfsburg cultural center act as an another type which present new principles of clustering, massing and exterior design. Its true meaning lies in forming a humanizing place beyond spatial configuration.

The large buildings in Korea usually use the generators to control the peak load of electronic consumption during the summer. It is necessary that these generators emit carbon dioxide, since they use gas or gasoline for their fuel. This study is to analyze the data of electronic consumption and operation of the generators at COEX, one of the representative complex building clusters in Korea, and to compare to the amount of carbon dioxide emitted per 1kWh from the domestic power plant by analogizing the frequency of using the generator during the summer and the amount of fuel consumption by the capacity of the generator and estimating the amount of carbon dioxide emitted from the generator.

Control of structural response due to seismic excitation in a manner of coupling adjacent buildings has been actively developed, and most attention focused on those buildings of similar height. However, with the rapid development of some modern cities, multi-story buildings constructed with an auxiliary low-rise podium structure to provide extra functions to the complex become a growing construction scheme. Being inspired by the positively examined coupling control approach for buildings with similar height, this paper aims to provide a comprehensive analytical study on control effectiveness of using friction dampers to link the two buildings with significant height difference to supplement the recent experimental investigation carried out by the writers. The analytical model of a coupled building system is first developed with passive friction dampers being modeled as Coulomb friction. To highlight potential advantage of coupling the main building and podium structure with control devices that provide a lower degree of coupling, the inherent demerit of rigid-coupled configuration is then evaluated. Extensive parametric studies are finally performed. The concerned parameters influencing the design of optimal friction force and control efficiency include variety of earthquake excitation and differences in floor mass, story number as well as number of dampers installed between the two buildings. In general, the feasibility of interaction control approach applied to the complex structure for vibration reduction due to seismic excitation is supported by positive results.

With an awareness of the fact that influence of building industry on the environment problems is great, many countries have been endeavoring to construct sustainable and environmentally-friendly buildings. In Korea, the GBCS (Green Building Certification System) has been in force since 2002. Total 6 types of buildings are dealt in the GBCS. Especially, it is expected that the number of apartment complexes, which are the most common type of residences in Korea, applying for GBCS has increased continuously. In this study, we aim to pick out the items requiring improvement for the green apartment complex. Existing 12 certified apartment complexes were selected. GBCS assessment results and actual conditions of design and construction were investigated and analyzed. Total 18 items requiring improvement were picked out in accordance with the average score-to-allotted point ratio. Relevant particulars expected to be helpful for the next design works were also presented.

주택유형의 변화와 친환경 주거에 대한 관심이 높아지면서 친환경계획요소의 정량적 검증에 대한 연구가 활발히 이루어지고 있다. 하지만 초고층 복합주거의 경우 친환경계획요소에 대한 정리와 실제 거주자들을 대상으로 한 만족도에 관한 연구는 미비한 실정이다. 이에 본 연구는 초고층 친환경계획요소를 단지, 건물내부, 설비 및 유지관리로 구분하여 실제 거주자를 대상으로 중요도와 만족도를 평가하였다. 또한 거주만족도(만족도, 충성도, 선호도)와 친환경계획요소의 영향 관계를 PLS 구조방정식을 통해 실증 분석하였다. 연구결과를 요약하면 첫째, 단지 친환경 계획요소의 개선은 만족도를 충족시켜 실제 거주자의 충성도에 영향을 미치는 것으로 나타났다, 둘째, 건물내부의 친환경 계획요소의 증가는 실제 거주자의 만족도와 선호도를 모두 충족시켜 충성도에 영향을 미친다. 셋째, 설비/유지관리의 친환경 계획요소는 실제 주민의 선호요인으로 도출되었으나 만족도에 대한 가설은 유의하지 않은 것으로 나타났다.

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.
