In this study, for the capacity estimation of emergency electric generators built in apartment complex using NEGA C 201 method, it was proposed application methods of simultaneously starting groups and demand factors. Also, it was suggested that capacities of the electric generator might be calculated for two kinds of electric facilities; one is loads for the convenience of tenants when main electric supply cuts off, and the other is loads for fire. For 7 apartment complex of large-size (about 1, 500 households), medium- size (about 1, 000 households) and small - size (about 500 households), electric generator capacities were calculated and electric power were measured. Through the comparison between calculated values and measured values, it could be proved the suitability of these application methods. In addition, the calculated electric generator capacities were appeared to fit into engin capacities by NEGA C 201 method as well as those by conventional method.

This study compared the feasibility of utilizing a wood bioenergy system over a conventional central heating and cooling system and a cogeneration system in an apartment complex. The performance of the three systems were compared in the following areas: energy consumption, environmental impact(output of CO2, CH4, and N2O), and life cycle cost. The results showed that energy performance of the wood bioenergy system was similar to the conventional central system (just a 1% improvement) but the cogeneration system showed a 12% reduction in energy consumption compared to the conventional system. In terms of environmental impact, the bioenergy system reduced pollutants by 50% while the cogeneration system reduced pollutants by 30% compared to the conventional system. Life cycle cost analysis indicated bioenergy and cogeneration to have an 8% and 19% improvement over the conventional system. The findings of the study suggest that it is both economically and environmentally beneficial to use a wood bioenergy system in place of a conventional central heating and cooling system in apartment complexes.

This paper aims at applying the data mining such as decision tree, neural network, and logistic regression to an unsold apartment complex in Wirye new town and developing the model forecasting the result of initial sale contract by house unit. Raw data are divided into training data and test data. The order of predictability in training data is neural network, decision tree, and logistic regression. On the contrary, the results of test data show that logistic regression is the best model. This means that logistic regression has more data adaptability than neural network which is developed as the model optimized for training data. Determinants of initial sale are the location of floor, direction, the location of unit, the proximity of electricity and generator room, subscriber's residential region and the type of subscription. This suggests that using two models together is more effective in exploring determinants of initial sales. This paper contributes to the development of convergence field by expanding the scope of data mining.

This research has been implemented based on the area of #369 Dowon-dong, Dalseo-gu, Dae-gu which is considered as a place with satisfactory characteristics for the flow of fresh air into the city. Simulations of the target area both prior to the development plan and after apartment complex blocking were analyzed in regard to blocking planning and pilotis based on the main direction of wind, $90^{\circ}$ (east wind) and $180^{\circ}$ (south wind). In addition, congested wind corridor flow in the target place was identified through a pollution spread simulation according to the wind corridor. Therefore, the flow of wind in the one area is affected by the blocking of the complex and the main direction of the wind. Also blocking, in regard of pilotis, provides a better flow of wind. This study was implemented based on wind formation by apartment complex planning, so further study on the other factors affecting the flow of a wind corridor along with block planning and pilotis need to be carried out. Sustainable environmental factors through analysis of the environmental factors have to be analyzed. Moreover, building and complementing fundamental resources and systematic devices should be supported.

This study aims to develop a model that can automatically identify the rooftop shape of apartment buildings using GIS and machine learning algorithms, and apply it to analyze the relationship between rooftop shape and characteristics of apartment complexes. A database of rooftop data for each building in an apartment complex was constructed using geospatial data, and individual buildings within each complex were classified into flat type, tower type, and mixed types using the random forest algorithm. In addition, the relationship between the proportion of rooftop shapes, development density, height, and other characteristics of apartment complexes was analyzed to propose the potential application of geospatial information in the real estate field. This study is expected to serve as a basic research on AI-based building type classification and to be utilized in various spatial and real estate analyses.

In Contemporary residential area, especially apartment commplex, crime affect the quality of life and sustainability of cities. So our interest is an all-time high in the role that planning processes and the design of the physical environment can play in reducing the opportunity for crime. The purpose of this study try to find the possibility of application of CPTED in Urban Apartment Complex. Recently, as increase of residencial density, diverse and new types of crime are increasing in urban apartment complex. It is the current of times which demand our serious consideration. This research focused on crime reduction through the physical environmental control methods. And the concepts and contents of CPTED are studied and the case studies of developed countries are surveyed. For groping in the practical application, researched into the case study of apartment blocks in medium sized city, Cheongju.

During last 4 decades of industrial development, apartment has been rapidly disseminated throughout the nation. Its main progress, however, only appeared in quantity, not in quality. To promote housing industry in more way and to enhance peoples' life quality through the better housing environment, housing plan should be based on living items including furniture, appliances and etc. Not enough research has been done to find out living items for better house plan development and furniture design. Among living items, furniture reflects both directly and indirectly people's lifestyle and way of living. This study attempted to find out the pattern of furniture possession which people own in their bedrooms. An in depth questionnaire survey of 600 households was carried during the year 2000. A variety of patterns were found which indicated diverse living conditions within a very similar uniform multifamily apartment complex. The result of this study will be helpful to understand the living conditions in a more systematic way and to generate new concept for both residential unit plan and furniture design.

This study was intended to suggest the design alternatives of housing units which were developed on the basis of POE. The POE of the New Apartment Complex in Gimhae was carried out and on the basis of the results of this POE, the design alternatives of housing units were developed. The subjects were 372 housewives who live in the apartment houses sized 60m2 to 85m2 in Gimhae. They answered about the living characteristics related to house, the degree of saisfaction with their housing unit plans, and the needs for housing unit plan. The major problems in current housing unit were the lack of storage space and the small size of living room and children's bedrooms. Many residents wanted to live in the housing unit which have three bedrooms and some of them wanted two bedrooms. Also, they wanted to enlarge living room and instead of that, to reduce master bedroom. In addition to these, the residents had diverse housing needs. On the basis of these results, housing alternatives which are flexible and optionable were suggested.
