A mathematical model is developed in order to describe the network configuration and heating distribution to a Central District Heating System for an Urban Residential Community. The purpose of using this model is to optimize operating costs and to distribute heat to the Residential Community efficiently. In particular, because of the inherent nonlinearity and dual optimization of the problem a dyamic programming approach is taken. It is turned out that the optimal cost of the system is a strong non-linear function of the network. In particular, it is found that increasing N, the number of houses, may not necessarily imply increased costs. It is felt that past failure of producing economical systems may be due to the improper attention given to the network.

ERV system has installed in almost newly constructed residential building in Korea. Heat recovery features of ERV can be possible to decrease the heating and cooling load caused by ventilation. However, in case of the outdoor condition is favorable to control the indoor air, the heat recovery function of ERV does more harm than good in term of cooling load. In this study, the ERV with economizer cycle control for residential building is suggested and the performance of the suggested system will be analyzed using TRNSYS.

In Korea, it is necessary to improve the performance of buildings with respect to the energy efficiency while improving the quality of occupants' lives through a sustainable built environment. During the design and development process, building projects must have a comprehensive, integrated perspective that seeks to reduce heating, cooling and lighting loads through climate-responsive designs. The aim of this study is to assess the optimal window-to-wall ratio of multi-rise residential units in the early design phase in Korea. The study analyzed the variation of annual heating and cooling energy load in two apartment prototype units located in Seoul city using different WWRs. The analysis was conducted using Autodesk Ecotect Analysis 2011 tool. The study found for total annual building load reductions WWR on the south and north face should be studied independently based on the room function. It also found reducing the WWR for bedrooms and windows on the northern façade resulted in reduced total annual building load.

As a lifeway and social change, the neighborhood build up around elementary school based on Perry's Neighbourhood Unit becomes change. Elementary School does not function as a center of residents' activity or community any longer. Activities occurred near the school move to the community streets that many facilities are distributed to, while utilization of facilities near schools becomes lower. On the bases of the current states, this study aims to draw a practical neighborhood center of residential areas by case study. The research is being mainly about low-rise residential areas in Seoul which includes one elementary school at least. In order to deduct the center of neighborhood, the survey takes two steps. At the preliminary survey, conduct the observation and do an interview to investigate awareness and actual status. Also to analyze practical center, do a main survey about land value, pedestrian volume, distribution of public transit and facility density. The research result shows that there is another activated center street not nearby elementary school in every case. This study assumes that the neighborhood center is not limited around elementary school and could variously build up by circumstances. It has significance that we present a question about the traditional theory and also could be references of the future city maintenance in the long term.

As the living standard of citizens are improving and the demand for the quality of life is increasing, the demand for the facilities of welfare and convenience for varied ages rises. Besides, our residential environment is faced with the need for changing into the environment of integrated function of living, which holds health, leisure, culture, education, welfare, etc. Considering the present reality requiring the augment of welfare facilities due to our aging society, community integrated facilities are needed, which can contain welfare service for home-living citizens within residential circle and can accept diverse needs of residents. Accordingly, the study began in order to suggest a better direction for community integrated facilities' plan that considers all age brackets for aging society. The study is to figure out way of thinking what community space of 3 age cluster middle-age in the 30s~40s, preparatory senior citizen in the 50s and old age brackets in the 60s~70s. As methods for attaining the aim of this study, surveys of documents and questionnaire survey were simultaneously used. The result of the study, investigating the importance of a community among the members in the residential complex, showed that all the age groups have highly perceived its importance. All the age groups responded that leisure are important to the elderly. It indicates that importance of their social relations are within the residential environment and it proves that there is lack of facilities for leisure activities of residents in apartment house.

The objectives of this study are to illustrate an alternative housing type responding to the social requirements and customers' needs, to suggest the improvement plan for the related laws and regulations through survey of the actual condition for housing buildings such multi have been raised in classification due to that the existing law systems including the current use classification of residential buildings have been defined unclearly. Especially, various social problems have yielded in line with emergence of the housing type which is not legally classified as residential however used for the living purpose practically. Current zoning planning and related law system have rigidity. So, It is required to introduce a flexible classification system which protects the residential environment based on the housing purpose, function and habitability and provides correspondence between residence and ownership/management method. The legal classification system should be revised in a way that the housing use classification corresponds with the zoning system through breakdown of the use classification system

Uncomfortable feelings of occupants by indoor floor impact noise in a residential building are not accurately represented by the floor impact noise from a standard impact source. It is due to the characteristics of standard impact sources, which are different from the impact forces produced by occupants. It varies significantly by impact source, and it is not easy to be replicated for testing. As a result, the indoor floor impact noise under different acoustic conditions cannot be directly compared. Using frequency response function(FRF), which represents the input-output relationships of a dynamic system, it is possible to examine the characteristics of the system. Especially, FRF can predict the response of a linear dynamic system subjected to various excitation. To determine the relationship between impact force and the corresponding response of dynamic system in residential building, the acceleration response of a concrete slab and the floor impact noise in the living room, produced by bang-machine and rubber-ball excitation, were measured. The test results are compared to the estimates based on FRF and impact force spectrum.

The purpose of this study is to find out a way to apply the strength of American homeowners association to Korean housing management system through literature review on the legal basis, organizational composition and functions, and management models of homeowners association. Following is distinctive characteristics of American homeowners association. 1) Homeowners association is a juridical entity which 'Condominium Act' obliges residents to join. 2) The board of directors is decision maker. The covenant, however, gives residents right to act in committees. 3) Homeowners association has self-governing functions such as management of common spaces, permission of new construction and taxation. 4) Types of management are volunteers' self-management, association-employed management, full agency management, and some mixed types. Residents pay management charge by month or by quarter. This study suggests as follow. 1) It is needed for Korea to legislate the law to regulate the management system of detached houses. 2)Management system of Korea can be more efficient with volunteers' committees for active participation. Above all, architectural control committee is essential in the circumstance that reform of apartment is popular these days. 3) The management entity is recommended to have some self-governing function to talk about taxation policy with local governments.
