Alongside the increasingly larger domestic construction projects is the gradual rise in construction waste. Consequently, serious environmental problems emerge. The increase in demand for housing remodeling due mainly to the increase in national income and improvement of quality of life is the main reason for the increase in construction waste. This study was conducted as the basic study for the prevention and reduction of construction waste generated by apartment remodeling; it aimed at identifying the remodeling items and reasons. Toward this end, this study targeted apartments at least 15 years old and conducted a questionnaire survey to determine the remodeled sections and remodeling reasons. As a result of the questionnaire survey, the bathroom, floor finishing, and kitchen furniture recorded the highest ratios in remodeling. Old materials, aesthetic motivation, and pleasant living space composition were cited as the major remodeling reasons. This study is significant as a basic study for generating environmental and economic profits through systematic waste management. Further studies should develop guidelines suitable for construction waste reduction and recycling in line with the construction and demolition phases in case of remodeling.

The purpose of this study is to provide necessary information for the establishment of remodeling range needed first to support the future remodeling of rural housing. For this, this study examined landscape characteristics of rural housing such as an outer wall, a roof, a fence, and a gate which are main elements of forming the landscape of a rural village and rural residents' perception for remodeling. The results were as follows. The subject rural housing mostly had a timber structure and a masonry structure. Common roof types were a hip-and-gable roof and a gable roof. Frequent materials were a panel, a tile, and slate and common colors were primary colors such as reddish brown, black, and gray. A fence made of cement blocks and finished by a white paint was often found. A closed gate with iron frames was common. A standup kitchen and a flush toilet inside the house were common. The family members of rural residents were mostly two including a farmer husband and his wife. Elderly people of sixty and over were the most common. For residential environment satisfaction, a half of respondents were not unsatisfied with residential environment mostly due to an old house. Most respondents who were not satisfied with residential environment had high perception for the need of remodeling. The most commonly asked remodeling part was a roof, followed by a toilet, and an outer wall, indicating that the need of exterior remodeling was higher than that of interior remodeling. For a remodeling method, a total improvement was preferred. Although some rural village housing was improved by support of the government, local governments, or social groups, there are still many old houses. As this co-existence of improved houses and old houses hinders the landscape of rural village, it is necessary to give a support. But rural residents' requests should be first actively reflected to establish a guideline of supporting rural house remodeling.

Markets for the apartment remodeling projects will be a major portion of the construction industry in near future. However, only partial remodeling works in the apartment were done so far. This situation caused bad impact to expand the remodeling markets and less profits of the remodeling projects. In order to solve this problem, many other researches were done previously to Improve profits of the apartment remodeling projects. However, the results are too theoretical to implement them and Improve profits. In this research, profitability influence factors that are possible to improve effect of the remodeling works are selected and analyzed through several studies. Then, correlation analysis is performed between the improvement level in the remodeling projects and the numerical profitability based on actual cases. The result clearly shows that some improved remodeling items are strongly related to the profit. These results lead us to the strategy to follow for the purpose of increasing profits of the remodeling projects.

As people pays more attention to remodeling as a method to effectively improve, maintain, and manage building properties, it is important to ensure the economic feasibility of remodeling compared to reconstruction, instead of focusing on systematic regulations. In order to identify core technologies, the study set criteria to survey cost of a remodeling project by analyzing current status of remodeling projects. Based on the criteria, the study calculated average construction cost for five remodeling projects that were conducted recently, compared the cost with new construction projects, and examined major level works that are essential in a remodeling project. Based on the major level works, the study conducted interviews with construction experts to draw core technologies in design, structure and construction of a remodeling project.

The purpose of this study was to investigate the policies related to residential remodeling for elderly households of Korea and Japan. Documentary research methodology was used in this study. The major results of this study are as follows: 1) It is not enough that the housing policy of elderly households prepare institutions and standards for aging society in Korea. 2) Residential remodeling projects by this time were not to improve residential environment of elder]y households but to support only a few low income elderly households in Korea. 3) Housing policy of elderly households consisted of design and remodeling standards for barrierfree of new housing and housing stock, housing financing, human resource network, and educational program of housing remodeling in Japan. 4) Central government and local self-governing body have support system which is systematic and that is helpful to those elderly households who needs housing remodeling in Japan. 5) It is needed that local self-governing body frame a policy of residential remodeling for elderly households. And central government and local self-governing body prepare the policy of financial support and contents of residential remodeling for elderly households according to the level of housing quality and residents circumstances. And they have the education system for specialist of residential remodeling for elderly households and clarify the standards of residential remodeling for elderly households. 6) In-depth analysis study is need to find a suggestion in many cases of advanced nations.

Due to economic or environmental reasons, green remodeling projects for old buildings are being actively carried out. Meanwhile, in the process of performing the green remodeling, the plan of green remodeling including passive and active elements has been decided based on the subjective experience and knowledge of engineers currently. Therefore, in this study, an ontology-based green remodeling decision-making support model, which can analyze the properties of old buildings and suggest appropriate remodeling plans, was established. In the developed model, once the basic properties of a building are entered, an appropriate remodeling plan composed of passive and active elements can be provided. By utilizing the results developed through the research, it is expected that it will be possible to support decision-making on more objective and appropriate remodeling alternatives development through web-based meta data search in accordance with the accumulation in remodeling cases.

More than 50% of the existing buildings in Korea are over 15 years old. Therefore it is necessary to be held reconstruction or remodeling deteriorated buildings more efficiently. Especially, since remodeling project reserves existing structures, it requires less period of project and construction period compare to reconstruction. It is possible to minimize uncertainty in communication between participants and able to manage information and construct efficiently in remodeling projects. This paper is first step of integrated BIM-based whole lifecyle management of apartment remodeling process. It suggests 3D laser scanner specification factors and site constraint factors for mapping between two groups. Therefore it will contribute to develop mapping algorithm of two groups and find optimal combination for apartment remodeling.

The purpose of this study was to provide the fundamental data for the effective housing remodeling plan. Through the questionnaire survey, the actual conditions of remodeling in apartment housing were investigated. And as the result of statistic analysis, the relationships between characteristics of remodeling and building life-cycle, and family life-stage, were found out. The major findings of this study are as follows; 1) Most of apartment residents have remodeled the family living space and private living space. In detail, they performed remodeling frequently the change of finishing materials, facilities and equipments, and the change of the location of curtain wall ＆ storage fixtures. 2) It might be predicted that the building life-cycle was influential variable to predict apartment residents' remodeling. Therefore, in planning the support service for the remodeling, the building life-cycle should be taken into consideration.

The rebuilding method for old apartment housing blocks has merits of providing new buildings and larger private living spaces. However, it causes many serious urban problems, such as shortage of infrastructure capacity, traffic congestion, reduction of building life, and deterioration of open space quality. Nowadays, remodeling is accepted as a way of overcoming such negative effects of the rebuilding method. This study focuses on the various techniques of remodeling. The results of this research are as follows; First, old apartment blocks provide poor level of service in general, so they have problems of bad accessibility, deterioration of facilities, and degraded landscape. In many cases, there is a hindrance from walking freely and security problem due to illegal privatization of public spaces. Second, various remodeling techniques are required to meet residents' different needs. The residents of apartment housing value private space above public space, and show low level of willingness to pay cost for remodeling. Third, based on these findings, some remodeling techniques are suggested - integration of a space to another, expansion of spaces, connection of spaces, reuses of roofs and walls, relocation and renovation of paths between buildings, and so on.

As hospitals change continuously and rapidly, the way of growth and change becomes another important factor in the design of a hospital. The hospitals are adapted for the continuous growth and change during their life span. But the hospitals built in 1970's and 80's have been expanded and reconstructed without any plan of growth and change. So, there is required to the architectural planning on the remodeling and modernization strategy of general hospitals. The purpose of this study is to provide the fundamental data for the reasonable design planning and the basic principles of the construction plan in the hospital remodeling. Thus, this study is to investigate and analyze the characteristics of hospital remodeling, the remodeling planning, and the scheduling process in terms of construction. As a result, this study would apply to design guideline for the remodeling of general hospitals.
