Grenfell Tower was renovated in 2014 and 2016 at a high cost to replace the exterior materials, windows and co-heating facilities of the building. The exterior materials used during the repair work were sandwich panels filled with polyethylene and plastic, which were expanded on the aluminum metal surface. It is a product called Celotex RS 5000, a low-resolution but inexpensive repair material, and is currently an external material that cannot be used in high-rise buildings. Similar domestic fire cases began to focus social attention on the safety of high-rise buildings through the Busan Residential Complex Fire (2010), Uijeongbu Urban Living Housing Fire (2015), and Ulsan Residential Complex Fire (2020), and residents' safety concerns are increasing. In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. Therefore, the purpose of this study is to examine the status of fire damage caused by domestic and foreign eruptions, domestic and international research status and related regulations on external materials and windows starting from the Grenfell Tower fire in England.

본 연구는 인천 게임산업단지 조성을 통한 경제적 파급효과를 분석하는데 있다. 게임산업은 문화콘텐츠 산업으로서 큰 잠재가능성을 가지고 있어, 발전에 대한 당위성이 높다는 다양한 의견을 가지고 있음에도 불구하고, 이에 대한 경제적 파급효과를 분석한 사례는 거의 없는 실정이었다. 따라서 본 연구는 이를 선험적으로 분석하는 측면에서 연구에 대한 의의를 가질 수 있다. 이의 분석을 위해 인천경제자유구역내에 게임산업단지를 설립하는 경우를 가정하고 건설부문, 게임관련 제조업 및 게임관련 서비스업을 토대로 지역산업연관분석을 실시하였다. 본 연구의 결과를 통해 게임산업이 지역 및 국가에 미치는 중요성을 직접적으로 파악할 수 있으며, 향후 이와 관련한 연구의 방향에 큰 영향을 미칠 수 있을 것이다.

Buildings with multi-complex spaces designed for architectural values and functional requirements give rise to technical challenges in terms of energy efficiency and thermal comfort. Since spaces in such buildings are connected with openings with geometrical complexity, it is hard to define zoning plan and to control heating/cooling loads effectively. This paper presents a case study on the evaluation of operation strategy for a building with multi-complex spaces using computer simulation. The modelling methodology and the results of the simulations are also described.

The accelerated development of new materials, technologies and construction processes, in parallel with advances in computational algorithms and ever growing computational power, is leading to more daring and innovative architectural and structural designs. The search for non-regular building shapes and slender structures, as alternative to the traditional architectural forms that have been prevailing in the building sector, poses important engineering challenges in the assessment of the strength and mechanical stability of non-conventional structures and systems, namely against highly variable actions as wind and seismic forces. In case of complex structures, laboratory experiments are a widely used methodology for strength assessment and loading characterization. Nevertheless, powerful numerical tools providing reliable results are also available today and able to compete with the experimental approach. In this paper the wind action on a free-form complex thin shell is investigated through 3D-CFD simulation in terms of the pressure coefficients and global forces generated. All the modelling aspects and calibrating process are described. The results obtained showed that the CFD technique is effective in the study of the wind effects on complex-shaped structures.

National Housing in Janghang was built intensively from the mid 1970s to the early 1980s, and has become a collective complex at Jangma-ro and Shinchangdong-ro. This Company House is a typical building for employee welfare, at the same time shows modern industrialization and urbanization. In general, it forms a housing complex and serves as industrial town. Reflecting the characteristics of Janghang, the housing complex is called National House based on the supply method and is also classified French Styled House in terms of housing style. Although Janghang was one of small local administrative units, it pursued urban style with mini-2-story. It has the typical characteristics as follows: division of the owner's living space and rental room, and independent layout of restrooms and washrooms. House is transformed to accommodate residents' lifestyles, so National Housing Complex of Janghang has undergone various changes such as the replacement of spatial structures and exterior materials for 40 years after construction. National Housing in Janghang is a symbol of local identity and an important spatial asset that shows the urban and architectural characteristics and changes.

Building Information Modelings(BIM) are more complex than typically required for early phase of the design process of a building. Construction projects have many participants from various disciplines involved throughout the entire process. Therefore the success of the project greatly depend on the efficiency of decision-making using the information generated from each process stage. This research utilized an ontology to provide an underlying structure of objects and relationships of a building. The OWL is introduced as a main vehicle to encode the information and knowledge about the building structures and spaces. A case study was conducted to develop a structured representation of an ontology where the relationships among the necessary components in the stage of preliminary design were to be automatically utilized to plan on the sizes of each room in a building and structured thoroughly with a simple structured representation.

The shapes(mass) of buildings are determined by many interrelated factors, such as planning and building regulations, the size and shape of building parcels, and adjoining road conditions. Understanding the effects of the determinants on the building shapes is not a simple task because of the multiplicity and complex interrelationships of the determinants. This study developed a prototype of three dimensional computer model that can simulates the determination process of building shape using GIS and CAD techniques. A commercial block in the south of Seoul was selected for the case study. Several methods of building height control were applied, and their effects on the cityscape were evaluated. The results shows that the three dimensional computer modelling offers an effective means for evaluating the effects of planning and building regulations. The implication of the case study and future research directions were discussed.

In this study the relative effects among trees, cars, wires and building facades on visual preference are measured with the photo-montage scenes, which were synthesized by computer graphic programs. In addition to these experiments, the interaction of each elements of streetscapes have been investigated. The results of this study can be summarized as follows ; (1) It was found that trees had a remarkable positive effect on preference for streetscapes, wires had a moderate negative effect, cars had a trivial effect and the effects of building facades were medium. (2) It was investigated that the building of residential type was most preferred among commercial, residential, and office building types. The next preferred building facade was the commercial type. (3) The interaction of each element of streetscapes also have effects on preference. Especially, it was found that the combined effects of building-wire and building-cars were more notable than other combined effects of two elements.

House supplying rate of building facilities is over 100% in 2008. In modern society, many people are thus interested in maintenance phase of building facilities by environment improvement budget because 20 years or more of building facilities are increasing rapidly. Maintenance of building facilities is depending on various factors that impact on the environment improvement budget of building facilities. However, Various methods and factors are made up complex relationships. I will analyze that environment improvement budget associated with floor, gross area, local, school type, service life and other elements.

There is a limit to preventing various types of safety accidents in advance at construction sites. Even for buildings of the same total floor area, it is expected that the more complex the building shape or the higher the number of floors, the higher the probability of a safety accident. Therefore, it is necessary to analyze the effect of the shape of a building on safety accidents using safety accident data generated during actual construction. The purpose of this study is to analyze the impact of building shape on safety accidents. As a result, the R2 value of shape factor and safety accident was 0.901, and the R2 value of construction difficulty and safety accident was 0.944. In the future, the results of this study will be used as basic data for improving safety management related systems.
