Management process of apartment buildings construction has increased because the after service of construction company meet the needs of customers. Many defect data, which was inspected by construction company or customers before moving into a new apartment house, were classified by field engineers and then communicated to corresponding subcontractors. The classification process needs to be performed by an expert engineer because there is so much data, it is unfeasible to complete in a short period of time. For this classification process, an automatic classification system using case base reasoning (CBR) should be considered. This research proposed a defect management system with automatic classification system using CBR. This constructed defect management system consists of cyber after service system for tenants and the whole defect management process of construction, preservation and management of apartment buildings. This system could improve the efficiency of expert work in terms of time and accuracy, as well as helping laymen users to conduct defect classification work as experts do.

This study was to find out contemporary planning characteristics of rural houses in Na-po Munhwa village by analyzing their floor plans. These results were then compared with apartment housing trends. 240 houses were built in that village, but it was only possible to collect housing data, floor plans and general building records from 102 houses, using house registers. By analyzing those data, the findings were as follows: 1) Floor plan shapes of rural houses showed a tendency to words a 'ㅋ' shape, a 3bay or a transformed 3 bay and a "room-living-room" space arrangement of a centered living room. Public spaces (L.D.K) were separately planned DK from livingroom. Living space was very open and the DK space had created visual privacy from the entrance. The Anbang (master bedroom) and living space were set to the front of the floor plan and an interior toilet was planned in them. These floor-planning tendencies were similar to trend apartment houses in urban areas. 2) Utility and Balcony spaces as a support space of kitchen were not popular features of rural houses in the Munhwa village. These results were different from urban apartment housing trends. 5) Storage space practically absent in those rural houses, and this was similar to urban the trends in urban apartment houses.

The purpose of this study is to summarize the changes in virtual reality utilization in model houses through the time-by-year example of model houses and to study the use and future development of virtual reality technologies in model houses. As a result of compiling and analyzing characteristics of virtual reality utilization flow in model houses of apartments, it is as follows. First, the market for apartment model houses using virtual reality was gradually expanded for the purpose of brand promotion by private construction companies. Second, technologies that utilize virtual reality in apartment sales are changing from virtual space construction to virtual content implementation. Third, it is changing from the existing method of face-to-face and method of accessing actual promotional media to the form of publicizing apartments using virtual reality. Through this research, it is estimated that it will be used as an information medium and a form of experience using physical environment and virtual reality in a physical model house for consumers looking for model houses. This study presents the future direction of the model house, and develops it as a post-sale maintenance / management system through ICT technology (3D scanning, 3D modeling, virtual content) Further research on the technology is expected to be needed.

In the summer, the irradiated solar heat gain through the roof has an effect on the thermal environment of the top floor units of apartment houses. This paper investigated the differences of the indoor air temperature, globe temperature and thermal comfort index between the top floor unit and the middle floor unit by measuring them at the sample units on the condition that all the openings of the units are opened. The purpose of this paper is to provide quantitative data about the irradiated solar heat gain during the summertime through the roof of an apartment house and these data to be the source to reevaluate the appropriate roof insulation efficiency. From this study, we obtained three brief results as follows. Indoor air temperature difference between the two sample units shifts a day. Indoor air temperature at the top floor unit is $0{\sim}1.8^{\circ}C$ higher than that of the middle floor unit from 12:00 p.m. to 12:00 a.m. and $0{\sim}2.8^{\circ}C$ lower from 12:00 a.m. to 12:00 p.m. The evaluation of the indoor thermal comfort index and the globe temperature shows similar results as the indoor air temperature measuring. Results of this experiment verified the actual existence of indoor air temperature difference between the top floor unit and the middle one and this difference comes from the heat storage of the roof.

The Korean fenestration energy consumption efficiency rating system only considers thermal performance of the heat transfer coefficient (U-value) and airtightness excluding optical characteristics of the solar heat gain coefficient (SHGC). This study analyzed annual heating and cooling energy requirements on the middle floor of apartment by optical and thermal performance of windows to evaluate the suitability of the rating system. One hundred and twenty-eight windows were analyzed using THERM and WINDOW 7.4, and energy simulation for a reference model of an apartment house facing south was performed using TRNSYS 17. The results showed that window performance was the main factor in the heating and cooling load. The heating load of the reference model was 539 kWh to 2,022 kW, and the cooling load was 376 kWh to 1,443 kWh. The coefficient of determination ($R^2$) of the heating and cooling loads driven from the SHGC were 0.7437 and 0.9869, which are more compatible than those from the U-value, 0.0558 and 0.4781. Therefore, it is not reasonable to evaluate the energy performance of windows using only the U-value, and the Korean fenestration energy consumption efficiency rating system requires a new evaluation standard, including SHGC.

Recent decreased number of family members have caused at least one spare room which is not used as a bedroom in an apartment house. In addition, people who need an apartment house cannot be satisfied with the typical unit plan any more, and rather request more various types of living space. Based on this kind of housing needs trend, we would like to analyze and classify dwelling unit planning methods which may create particular purpose extra rooms to satisfy their unique needs and to give characteristics and individualities by means of study on various cases. As a result of this study, we could find the following planning methods which can produce extra rooms : 1) Utilization of optional plan between living room and adjacent bedrooms, 2) Utilization of optional plan on master bedroom zone, 3) Insertion of transitional space and Utilization of spare space, 4) Insertion of a space for housewives near a kitchen, 5) Positive utilization of a balcony space. This study is also trying to show many unit plan cases of which planning methods can be applied in other cases.

In line with the worldwide trend toward the protection of natural environment and economic concerns, the steel framed house is suggested for the next industrialized generatiov. In Korea, untrustworthiness of concrete structured apartment has led to the development of alternative building material and technology. POSCO has constructed the model steel house to assess the marketability of steel framed house in Korea. To collect basic data required to design the steel framed house suitable to Korean life pattern and housing needs, professional evaluation of model steel house was conducted. The goal of this study is to propose alternative plan and ideas on the interior space planning based upon the evaluation from women housing professionals. Our analysis reveals that the habitability of steel house is equal or superior to that of traditional houses. But in the interiior sapce planning, the certain aspects of steel houses is not suitable to Korean likfe style: the lack of storage space and utility space, inflexibility of plav. We conclude that given its cost efficiency and environmental concern, steel house has potential to take an important part in future Korean housing.

Model house play an important role in the sale of apartments. However, model house can create social and environmental problems. Virtual reality's (VR) use for the creation of model house has been studied as a possible counter measure to these problems. Existing models don't satisfy consumers' queries. A virtual model house can give the experience of seeing a real home through simulation. Also, a virtual model house can allow a home buyer to change the furniture on display or the color of the walls to reflect the consumer's taste in the construction. The internal present condition system using absorption style virtual reality and open style virtual reality are the indispensable tools that are going to take the place of the current model home. A virtual model house is more profitable than a physical model house because of reduced costs and time savings. In addition, a virtual model house can offer new kinds of information that a physical model home can not. This study's purpose is to discuss the desired direction of the virtual model house in this crucial and dynamic period of development.
