The effects of an apartment complex on flow and pollutant dispersion in an urban area are numerically investigated using a computational fluid dynamics (CFD) model. The CFD model is based on the Reynolds-averaged Navier-Stokes equations and includes the renormalization group k-${\varepsilon}$ turbulence model. The geographic information system (GIS) data is used as an input data of the CFD model. Eight numerical simulations are carried out for different inflow directions and, for each inflow direction, the effects of an apartment complex are investigated, comparing the characteristics of flow and dispersion before and after construction of the apartment complex in detail. The observation data of automatic weather system (AWS) is analyzed. The windrose analysis shows that the wind speed and direction after the construction of the complex are quite different from those before the construction. The construction of the apartment complex resulted in the decrease in wind speed at the downwind region. It is also shown that the wind speed increased partially inside the apartment complex due to the channeling effect to satisfy the mass continuity. On the whole, the wind speed decreased at the downwind region due to the drag effect by the apartment complex. As a result, the passive pollutant concentration increased (decreased) near the downwind region of (within) the apartment complex compared with that before the construction.

The purpose of this study was to investigate the residents' actual usage at three rest areas and three playgrounds in an apartment complex. This study was conducted with field study in J apartment complex in Incheon from August 14 to August 30, 1998. According to the results of the study, there were more users in playgrounds than in the rest areas. The rest area near the place for the elderly in the complex was used mainly by the elderly females. The playground located near the main entrance of the complex was frequently used because it is the biggest one in size and has an enough space for playing. Furthermore, the condition of shading areas by trees and buildings influenced the rate of use of the residents. Therefore, to increase the usage rate of rest areas and playgrounds, they should be located near to the places which have community amenities and should have accessible entrance for residents. Landscape design of the apartment complex should be done with the plot plan of the complex simultaneously. Moreover, the number and the kinds of trees to be planted in the apartment complex should be considered carefully.

In the case that high-rise building is constructed, the surrounding wind velocity increase more than 50~100%. From this cause, many wind environmental problems can be occurred. For example, ordinary wind environmental disaster may be occurred in a region, or walking disturbed. In developed countries including USA, EU, and Japan, many efforts have been made for building wind prevention by grasping previously the effects before building constructed. But, We are bearing risk of wind environmental disaster because we have not enough recognition about building wind, and have not architectural prevention counterplans. This study aims to examine wind environmental characteristics of domestic apartment complex, and effective architectural counterplans. As the basic stage for this, we investigated pre-estimate tools and risk assessment methods of building wind in apartment complex, applied to two apart complex in Cheon-An region by CFD. As the result, serious damages were not presented. But, it is obvious that various architectural counterplans will be presented by this example researches.

Many business enterprises in domestic housing industry are focusing on the development of environment friendly apartment complex to strengthen the competitiveness by upgrading their company's image through differentiation of the qualities and satisfying the customer's needs. Many apartment complex have achieved temporary or real certification by green building certification system, but there weren't enough studies on how much residents are satisfied by their certified complex. In this study, we want to clarify the factors of resident's satisfaction level in certified environment friendly complex by comparing the social and economical characteristics of resident. For this study, we chose and compare 4 environment friendly apartment complex considered to be built by the best environmental way in metropolitan area, and 4 other apartment complex which are also considered to be similar in terms of the condition of location and period of stay.

In Korea, an environment-friendly concept of "rain re-cycling" was initially introduced in apartment complex planning and designs in the late 1990s. Although its application cases are extremely few, with the growing importance of rainwater utilization, introduction of rainwater management facilities in urban areas began to drawn keen attention. In urban areas also, plans to introduce rainwater management facilities in apartment complexes as infrastructure improving living environment, such as sewage treatment facilities are very urgently required. In order to introduce rainwater management facilities as infrastructure in an apartment complex, apartment complex cases that had introduced the facilities were reviewed first. In this study, a few applied rainwater management facilities in an apartment complex were surveyed(Infiltration barrel, Rubble porosity storage tank, Underground storage tank). As a result, problems in introducing rainwater management facilities in apartment complexes in Korea were identified.

This study was to confirm the effectiveness of crime prevention in an apartment complex environmentally designed for domestic crime prevention. The researchers surveyed 267 residents on the community, fear of crime, and crime victimization. They arrived at the following conclusions. The authorization complex received higher security satisfaction results than the unauthorized complex; residents were less afraid of crime and more active in the apartment complex community. These results differ from previous studies in that the fear of crime is not related to a crime victim experience and that the fear of crime is low when there are less households in the apartment complex. Therefore, effectiveness of crime prevention abroad should not be accepted in a domestic residential environment.

With the rate of spread of motors rapidly increased, but parking difficulties in an apartment complex was aggravated due to an insufficient parking lot. Visual interference on residential environment, various kinds of pollution and noise, decrease of open space in an apartment complex are also causes of parking difficulties. Therefore, this study is to suggest a theory of desirable direction for planning of the parking space by studying psychological characteristics of users' behaviors by the type of the circulation of motors and pedestrians. Consideration on the present situation, real conditions of underground parking space and the consciousness and parking habit of residents, the most important problem is required in this study.

This study tried to prove why a low-rise residential block is more vitalized than in a superblock consisted of an apartment housing complex. To do this, two adjacent superblocks in Yeoksam 2-dong were selected as a case study among superblocks of residential area in Gangnam, Seoul. It adopted the concept of 'complexity', 'Osmosis', 'Vitality' and 'Permeability' for evaluation indexes to measure street vitality. As a result, four indexes were clearly higher in low-density residential superblocks than apartment housing complex superblocks. First, the superblocks for apartment housing complexes showed a lower 'complexity' because large-scale parcels for an apartment housing complex reduces a possibility for various land uses. Second, smaller blocks improved "osmosis" compared to larger blocks, and the larger the block, the less likely it is that buildings and streets penetrate activity. Third, as the apartment complex block became larger, the number of accesses decreased. Thus, it did not provide vitality to the streets. Fourth, high permeability was shown in the low-density superblocks, while that of the superblock consisted of apartment housing complexes was very low because the entrance of the complexes entrance is closed to the public. The results of this study demonstrated that an apartment housing complex may hamper street vitality and deteriorate the quality of urban environments.

The purpose of this study is to accumulate basic data to establish planning direction and planning factors for the environment-friendly apartment complex. For this purpose, the survey has been conducted to residents living in an apartment housing and graduate students, architects and research experts in the field. The major findings of this study are as follows; 1) The basic concept of planning factors for environment-friendly apartment complex are energy saving, resources saving, minimizing environment pollution, natural harmony, regional identity and pursuit of residents' health & amenity. 2) For the planning factors of environment-friendly apartment complex, the residents had a great regard for aspect of Low-Impact (energy saving, resources saving, minimizing environment pollution). The experts, on the other hand, had a great regard for aspect of High-contact (natural harmony, regional identity). 3) It was increase of prime cost that the residents and experts regarded as the most important problem of planning and purchasing of environment-friendly apartment. It thus appears that the promotion of environmental consciousness of residents taking in the portion of increased cost is crucial parts and also that the role of the connected aspects such as administration, construction companies and residents must be redefined in order to manage problems caused in process of the development of it.
