Recently, tower type apartment has been a main stream at the apartment market, in Korea. Tower type apartment has features that is easy to maintain a proper distance between apartment buildings, and to keep a prospect comparing to flat type apartment However, there is usually a inner curved area at tower type apartment, and it is able to make an unhealthy environment because of shaded area through a day and a bad air flow. In this study, the duration of sunshine and the exterior air flow environments are examined. As results, the duration of sunshine at the inner curved area of tower type apartment was extremely short, and the exterior air flow environment was very bad for the low air velocity of about 0.08m/s. Installing pilotis in the 1st floor which faces to the inner curved area makes the good improvement of exterior air flow environment.

As the consumer's consumption standard has raised, occupants' needs for the apartment is diversified and complicated. But the existing mass housing supply method has many problems and it couldn't satisfy the dwellers' various needs and overall expected life span. In order to correspond those needs, construction firms have introduced several method, such as plus option, minus option, on-time option, change up service and so on. The custom-built apartment is more supplementary and it can reflect the consumer's needs to the apartment directly. But after running the custom-built apartment, several problems is revealed. So. in this study, I defined the general idea of the custom-built apartment and then collect the case of the custom-built apartment.

This study was conducted to analyze the status of apartment informationalization through the research of distribution of super express network, apartment home pages and Inhabitants awareness. 1st. The construction business launched the full-scale apartment informationalization in 1999. Since then, the infomationalization has been developed multilaterally while the apartment home pages are playing a major role in cooperation with construction business and Internet business. The academic interest and research on the informationalization, however, are not enough. 2nd. The distribution of super express network, which is based on the informationalization is accelerated by the government policy. Especially in our country where the apartment is the major type of housing, we have favorite environment for the informationalization and can create our own housing culture. 3rd. The number of the apartment home pages now is increased to over 6,000, but its contents, know-how, and technique to build the system have not been advanced enough. 4th. So far the home pages have not been able to function well enough to strengthen the community awareness and are likely to result in the unbalanced informationalization. 5th. The study shows that residents interest in the computer and the Internet is fairly high. The utilization of the Internet is varied according to the age, sex, occupation, academic background, income and so forth. Especially they are not as interested in the housing informationalization as in the general information, but the preference of the apartment home pages and the super express network is so tremendous that its distribution will keep the momentum.

In 2009, The Ministry of Land, Transport and Maritime Affairs, Korea opens apartment maintenance fee to public in "Apartment Management Info System". The high energy consumption component of apartment, which is hot water, water, electricity and heating, is released to public on this system. Through this system, apartment energy consumption and greenhouse gas emissions data can be compiled and expected to be accurately analyzed. Energy consumption and greenhouse gas emissions statistics of the apartment are collected being made to reduce energy and gas emissions. However, The accurate survey of energy consumption trends have not been accomplished. The energy consumption and greenhouse gas emissions survey in Apartment should be made first in order to reduce energy consumption. and then the correlation factors analysis which is affecting energy consumption is required. The purpose of this study is to analyze energy consumption characteristics of apartment in Bundann-gu, Seongnam, Korea in monthly, unit area and building built year basis. And then the research can be used as the basis of policy to Reduce energy consumption and greenhouse gas emissions.

The purpose of this study is to provide the feasibility of apartment remodeling types in DaeJeon City. This study was conducted by survey for the residents' perceptions of the apartment remodeling. In addition, this study estimated the cost according to remodeling types by comparing it with that other apartments in DaeJeon City. By doing so, this study evaluated the feasibility of remodeling. The results of this study are as follows: 1. Not only the level of the residents' perception but also the intention of apartment remodeling was high. 2. The cost of remodeling was similar to that of residents had answered at questionaire. Thus, the remodeling cost proven to be very reasonable. 3. The cost of horizontally expanding remodeling type was cheaper than that of moving within the same apartment complex or into the new apartment. The cost of others (duplex, expansion or reduction of household) are cheaper that of moving. But one of the difficulties in carrying out these types lies in the fact that the remodeling should be performed in the apartment complex or building. Accordingly, this study proposes that horizontally expanding remodeling type is more feasible in DaeJeon City.

This study aims to verify the effects of the apartment office managers' servant leadership on the residents' satisfactions and housing management company contract renewal ratio, and to examine whether the number of apartment units and the apartments' average size have the moderating effects upon the relationship between servant leadership and the residents's satisfaction and housing management company contract renewal ratio. For the purpose of testing the hypotheses, the questionnaire survey was conducted targeting 1,000 apartment office staffs and 8,000 apartment residents of 200 apartment complex in the region of Ulsan, Kyungnam, and Busan, and the statistical analyses were carried out for the useful questionnaires of 961 apartment office staffs and 7,119 apartment residents. The main results are as follows: First, the higher the office managers servant leadership is, the higher the residents' satisfactions. Second, the number of apartment units and the average size have moderating effects on the relationship between the office managers' servant leadership and housing management company contract renewal ratio. Finally, the summary, implications, and limitations of this study, and the future research direction were discussed in the conclusion.

Most of customer satisfaction researches that have announced by mass medium about an apartment house intend to do not fairly consider the premium of an apartment house. Thus, the researches offer the wrong information to a lots of companies and customers that want to objectively assess quality of an apartment house through comparing an apartment complex with another and construction ability of company. Therefore, this study analyzes that the premium of an apartment house affects customer satisfaction, derives indexes which affect premium of an apartment house, and do an importance analyses with each other. Then this study purposes to be of use with the foundation material for the objective index assessment of premium of an apartment house.

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.

In Korea, the apartment buildings have been constructed recently in large quantities to provide housing due to the gravitation of population towards large cities. However, because of this trend toward high-rise apartment, a number of problems are occurred such as the deterioration of comfort in the dwelling environment and the lack of solar access right in apartment buildings. In the building law, the sunshine hour and the minimal separated distance between apartment buildings as regulated as the criteria for the site planning. Most of site planners, however, designed the apartment site only following minimum separated distance. As a result, the problem of sunshine hours lack is caused and legal dispute concerning solar access right is also arisen. The purpose of this study is to improve solar access right regulation and to help site design of apartment planning. Accordingly, we execute empirical analysis based on computer simulation in order to find suitable separated distance between typically designed apartment buildings. First, we estimated sunshine hours according to independent building orientation, height, and length. Second, we calculated sunshine hours in various case of apartment arrangement; parallel type, courtyard type, tower type and etc. with various separated distance.

More than 23% of total nation's energy is consumed by residential building and 57.2% of Korean people are living in apartment. This study was carried out to two kind of process. First, after selecting one standard apartment, our research team investigate realistic energy consumption. Second, using 3-dimension heat transfer tool(TRISCO RADICON) and building energy simulation tool(Visual DOE) As a result, amount of heating and hot-water energy is composed of above 80 percent in standard apartment. And, after applying high performance technologies to standard apartment, namely, after being green home apartment, total energy consumption is reduced by54.6 percent. Also, because of energy consumption characteristics of green home apartment, for making more high performance green home apartment, especially, we have to figure out effective method to reduce electric and hot water energy.
