This study aims to propose the comprehensive evaluation of performance multi-family housing. Most of the existing studies for the reproduction have evaluated by the safety of structure. Therefore those pass over the functional factors which is important for the evaluation of residential qualities. This study represents that the reproduction renovation should not be secured the safety of structure but established the quality of lift. And questionnaire asking expert's opinion also supplemented. As a result, the item for examination and the weight for evaluation are suggested in functional deterioration. The results of this study are summarized as follows: 1. Existent redevelopment criteria are not appropriate to decide the environmental comfort, the vital function of housing and the residential management finance. 2. The future criteria have to evaluate the existing environmental comfort, be reconstructed to put first general deterioration. 3. Evaluation elements was extracted throughout the document research, evaluation elements analysis system was separated in residential area, suburb of dwellings, community, and housing complexity environmental assesment, 4. Each category of influence ratio was extracted to assess total deterioration throughout the expert question survey. 5. Each category analysed (1) $0{\sim}30%$: function is good (unnecessary to improve) (2) $31{\sim}40%$: average (necessary of partial improvement) (3) $41{\sim}59%$: bad (necessary of total improvement) (4) $60{\sim}100%$: the worst (unable to improve throughout the repair)

Since 1980s' Korea had a great change on the housing culture by the supply of multi-family housing stock both on the macro-social and micro-social aspects. The purpose of this study was to examine the changes and the characteristics of housing environments which were estimated its modernization, and to examine the personal life under the change of housing environments. So I would like to revaluation the characteristics of modernization between the 1980s' and 1990s'. Therefore references were made to various papers, reports, the statistical data, newspaper reports, advertisements and magazines during that period. As a result, this paper came to the remarks as follows: 1. The success of modernization on the housing environments since 1980s' was the Quantitative growth of housing supply by multi-family housing. In spite of this, the Quantitative growth of housing supply and the improvement in Quality like housing space per person had the characters which was 'out of valence on the division'. 2. The Qualitative improvement of modem housing life by the development of housing industries could be said the improvement owing to develop of facilities and equipments. The introduction of up-to-date facilities and equipments realized the convenience and the rationality of living in the house. Although the improvement on the physical things deteriorated the modernized spaces to uniform things by commercial strategies. 3. The life in the multi-family housing which gives protection to personal privacy was settle down on the extremely individualized life without common things within the neighbors. Multi-family housing which was a production of process of modernization came true the growth in an appearance and the variety in the inside, but for the aspect of residents' everyday life in the multi-family housing, the Korean traditional relationship was collapsed and a sense of incompatibility within the residents was created.

Construction of Multi-Family Housing(MFH) was rapidly spread in the 1990s, it has been mostly passed more than 20 years and it is faced to aging time. Remodeling has emerged a major issue in the construction industry as an alternative of improvement and recovery the initial performance of the deteriorated MFH. But, Many decision-makers are struggling to determine whether to conduct a remodeling because of profitability. In this context, this research was conducted as the following steps to achieve this research goal, i) remodeled MFH cases and comparative cases were collected, ii) the price information based on three time frames (i.e., before remodeling, after remodeling, and present) was collected, and iii) the relative price variation of the remodeled cases was analyzed and finally it is revealed that there are four patterns of price variation.

In Korea, most of the historic city became a deteriorated area with low-rise settlement. It is revaluated as a s great potential in spite of slum clearance and redevelopment for a long while after 1970s. A great achievement for low rise multi family housing, in spite of these social change, is not easy to find the cases and social commonness. In the view points, this article deals a ideal model in historic areas, and the model should be get the understanding from the people, because acceptance from people is the beginning for making historic housing areas. The facade model for evaluation prepared as three types, and responses for the models processed by AHP(Analysis Hierarchy Process).

As the construction of multi-family housings, especially apartments, has been increased since 1970s, the multi-family housing becomes one of the main housing types in Korea. With the increase of multi-family housings, managing them becomes an important issue. Since 2010, the government has made a lowest price award system by a competitive bid compulsory to promote the development of housing management systems. Although competitive bids were implemented, the maintenance company was finally selected by the price without any other consideration. Consequently, the quality of management service was not enhanced. The purpose of this study is to suggest the improvement scheme of multi-family housing management system. In this study, the bidding data of "K-apt", the bidding method and the successful tendered price are analyzed. The results of analyzing bidding materials, the proportion of applying a lowest price system was 67.7%. Also many diverse ways to select the best management company were used, but most of these ways were violate the law and guidelines of Ministry of Land, Transport and Maritime Affairs. It meant that the lowest price award system was not implemented by strict standards and didn't correspond with the needs of residents of apartment. This condition made the housing maintenance quality low and deteriorated the management industry development. To enhance this condition, a new standard to select the management company, which are included contents of quality of managing quality, management expenses and companies' soundness, is necessary.

This study is aiming at estimating the demolition cost of deterioration housing by the rational method in order to provide for the demolition and new build project of the rental multi-family housing of LH. We investigated the actual state of demolition construction and work process of small size housing, and analysed an actual condition of estimation for the demolition cost through an advice by the expert of construction cost estimate. Furthermore, the 'estimation standard for the predetermined amount', 'estimation standard for the disposal cost of construction wastes' and precedent studies in public construction work were considered. As one of results in this study, cost accounting system, breakdown system and construction cost for the demolition work based on the standard of estimate were proposed and the predetermined amount of demolition construction for the multi-family housing with 2 or 3 floors could be produced by them. Eventually, It is estimated that the demolition cost per a multi-family housing is about 18,331,000(won) and 104,000(won) per floorage($m^2$). To the details, the result indicated that the direct demolition cost needs about 14,339,000(won) per a multi-family housing and the consignment disposal cost of wastes needs 3,992,000(won) per one. The results of the study will be used as the fundamental data to estimate the project cost in the phase of budget establishment for demolition and new build project of the deteriorated rental multi-family housings, and also cost accounting system of demolition construction and breakdown system are expect to be used effectively at the ordering of public construction work.

As climate change is becoming the main issue, various efforts are focused on saving building energy consumption both at home and abroad. In particular, it is very important to save energy by maintenance, repair and rehabilitation of existing multi-family housing complex, because energy consumption in residential buildings is not only forming a great part of gross energy consumption in Korea but the number of deteriorated complexes is also sharply increasing. However, energy saving is not considered as a main factor in decision making on rehabilitation project. Also, any supporting tool is not appropriately prepared in existing process. As the first step for development of decision support system on rehabilitation, this paper developed a breakdown structure, which makes clusters of multi-family housing complexes. Decision tree, one of data mining methods, was used to make clusters based on the characteristics and energy consumption data of multi-family housing complexes. Energy saving and CO2 reduction will be maximized by considering energy consumption during rehabilitation process of multi-family housing complex, based on these results and following research.
