In Korea, in the case of fire scenarios in performance design, it is assumed that the sprinkler is not working. In addition, it does not applicate various fire conditions. Therefore it is not enough that the accuracy about fire scenario. In foreign countries, reseach is being conducted to predict the casualities that can occur due to fire in the building space through statistical risk analysis. Also, research is consistently conducting for design that consider the sprinker probability of operation. Therefore, to analyze the fire risk of each building in Korea, the risk was analyzed using statistical data. As a result, the risk of casualties that can occur for each building use was analyzed as 0.6(persons/cases) for residential buildings, 0.25(persons/cases) for sales facilities, and 0.12(persons/cases) for buisiness facilities.

The increasing need and use of 3D GIS particularly in urban areas has produced growing attention on building reconstruction. Nowadays, the use of close-range data for building reconstruction has been intensively emphasized since they can provide higher resolution and more complete coverage than airborne sensory data. We developed a fusion approach for building reconstruction from both points and images. The proposed approach was then applied to reconstructing a building model from real data sets acquired from a large existing building. Based on the experimental results, we assured that the proposed approach cam achieve high resolution and accuracy in building reconstruction. The proposed approach can effectively contribute in developing an operational system producing large urban models for 3D GIS.

In this study, I investigate the formation process of the American presbyterian missionary architecture in Cheong Ju area from 1900 to 1945, which we may think 'the part of Korean modern architecture'. I have examined and analyzed the 18 buildings for the sake of the interpretation with the words of formation process and characteristics . And I can put my idea in order as follows. Firstly, the formation process is 1) buy and modify a Korean style (thatch or tile roofed) building for their need and use it as a gate quaters or house, church, hospital, school, book store, 2) build a Korean style (tile roofed) building and use it-house, hospital, school, 3) build a Western style (timber structured and zinc roofed) building and use it- church, 4) build a Western style (masonry structured and tile or zinc roofed) building and use ithouse, church, school and hospital. Secondly, the characteristics is 1) In the Korean style building, the missionaries change into the function to match with their purpose. they modify the Korean style timber structure by influx of building material-brick, glass, carpet etc. they occupy into the Korean existing residential area. 2) In the Western style building, the missionaries build the house correspond with their living pattern. they build the church with the eclectic of Western and Korean timber frame. and also build the house and hospital with the eclectic of Western and Korean masonry structure. their building located in the isolate hill separated from the existing Korean residential area.

In this article, we look at the application of BIM (Building Information Modeling) in sustainable infrastructures. In response to global warming, energy shortages, and environmental degradation, people are trying to build eco-friendly, low-carbon cities and promote eco-friendly homes. A "green" building is the entire life cycle of a building that includes maximizing the conservation of resources (energy, water, land, and materials), protecting the environment, reducing pollution, providing people with healthy, comfortable, and efficient use of space, and establishing harmony between nature and architecture. In the field of ecological and sustainable buildings, BIM modeling can be integrated into buildings with analog energy, air flow analysis, and solar building ecosystems. Using BIM technologies, you can reduce the amount of waste and improve the quality of construction. These technologies create "visualization" of digital building models through multidimensional digital design solutions that provide" modeling and analysis "of Scientific Collaboration Platforms for designers, architects, utility engineers, developers, and even end users. Moreover, BIM helps them use three-dimensional digital models in project design and construction and operational management.

Over the past several years, the building codes that govern commercial building construction have become increasingly prescriptive in nature, specifying detailed information related to the design and installation of the systems, while offering no reasoning behind their prescriptive measures. For example, metal stud framing is commonly used in commercial building construction to create bearing walls and non-bearing partition walls. BIM provides a powerful platform for developing and implementing "pre-planning" tools and methods to facilitate both engineering and administrative controls during construction. This paper discusses the use of BIM to enhance constructability for commercial building construction activities, specifically metal stud framing. Using specific real-world examples this paper demonstrates ways that BIM can be used to foresee potential construction issues and motivates and informs future uses of BIM technologies

At the beginning the 21st century, we are interested in renewable energy especially photovoltaic. So, we have been installed PV at the building roofs so that we call it building integrated photovoltaic. But strictly speaking, installing the PV on the roof is not building integrated. There are few BIPV designs especially for balcony. In the apartment building, roof is good installing place for PV, but its area was limited. Now a day, built apartment building's heights are more and more increased so that the performance of installed PV on the roof cannot be enough to use even the public use. Thereby, we need the new space in the building to install the PV except the building roof. This study suggests the building facade balcony as a new space to install the PV with building integrated PV design. Hence, in this study, we are designed the movable BIPV shading device for apartment building balcony, and verified its performance with computer simulation. Developed device in this study can works as an electronic generation device and an overhang on the side balcony. As a result, the electronic generation performance of device contributes 15~30% to each apartment unit. The more unit width increase, the better contributed device generates.

This investigation is to question as to whether and how much urban residential superblocks have changed the uses of facilities, as compared with original zoning plan. The difference between the original plan for 'land use' in 1960's and current 'building uses' has been examined on six superblocks in Seoul, and the reasons for change were analyzed. Investigation results are as follows: As the original urban planning was intended for use-purification by the subdivision of zones in a superblock through zoning, current buildings uses are different from the land-use. Commercial facilities are located in residential zone along community paths because of the necessity, and business buildings are placed on the appropriate-sized lots in the middle of residential blocks, due to the need of small and low-rent offices. Also, different types of residence have been built on convenient locations in commercial zone to meet various housing needs. In conclusion, the current zoning system plays a role of controling the volume of buildings rather than the use of land. Therefore, mixed use of land, not functional separation, becomes a natural phenomenon taken place in the contemporary cities, and it is high time to adopt a mixed-use zoning system.

System Integration is significant role in building, because it is that the more building system is integrated, the more they can save management costs and energy costs. Nowadays system protocols in building use BACnet, LonWorks, etc. to integrate effectively, but their interoperability is not perfect. Therefore, we propose system integration using Ethernet and TCP/IP for perfect harmony. When data network protocol, Ethernet and TCP/IP is used for control network, there are several problems. But there have been solved by many researches. therefore it is possible that building system integrate to use Ethernet and TCP/IP. Finally, we show that Ethernet and TCP/IP can be used for building automation system integration.

Nowdays the most critical problem is global warming and the most important reason is the high emition of carbondioxide. 23% of the use of carbondioxide is used in building and decreasing the use of it is very important. One of the biggest factor that can decrease the use of energy is developing the heat conducting ratio of the materials we use in building. Heat conducting ratio is the important factor in the use of reducing energy comsumation. In this research, there are methods about how to measure the heat conducting ratio, and the existing the representing measuring method which is Heat Flow Meter HFM 436, Laser Flash Analysis and find out about the TCi of the new method C-Therm and compare the results.

There is growing consciousness of the environmental performance of buildings in Hong Kong. The Buildings Department, the Lands Department and the Planning Department of the Hong Kong Government issued the first of a series of joint practice notes [1] to promote the construction of green and innovative buildings. Green features are architectural features used to mitigate migration of noise and various air-borne pollutants and to moderate the transport of heat, air and transmission of daylight from outside to indoor environment in an advantageous way. This joint practice note sets out the incentives to encourage the industry in Hong Kong to incorporate the use of green features in building development. The use of green features in building design not only improves the environmental quality, but also reduces the consumption of non-renewable energy used in active control of indoor environment. Larger window openings in the walls of a building may provide better natural ventilation. However, it also increases the penetration of direct solar radiation into indoor environment. The use of wing wall, one of the green features, is an alternative to create effective natural ventilation. This paper therefore presents a preliminary numerical study of its ventilation performance using Computational Fluid Dynamics (CFD). The numerical results will be compared with the results of the wind tunnel experiments of Givoni.
