Korea has achieved a rapid economic development and with the increase in population and national income and the expansion of social and economic activities, energy consumption has rapidly increased too. Energy consumption per head has constantly increased and currently, power consumption per head is 7.5 times bigger than in 1985. Buildings occupy 25% of total energy consumption and especially, 50% of total energy is consumed for heating and cooling. In this situation, multi-family housing, which has constantly been increased, has an energy saving rate of 1.9%, which is the lowest level and this makes the government's energy policy for sustainable energy system development useless. Besides, energy consumption leads to secondary problems, such as air, water and marine pollution and heat pollution and wastewater/drainage and the increased use of fossil fuel is a fundamental reason for ozone layer destruction and global warming. Therefore, efficient energy consumption plans are required. This study aims to analyze energy performance in each block type of high-rise and diversified multi-family housing that accounts for 60% of all the housing forms, depending on the variations in stories through BIM-based energy simulation. For this study, four representative block types were selected, based on the multi-family floor plan, which is certified for energy performance evaluation and they were applied to the floor plan of a multi-family house that is scheduled to be built. Then BIM modeling was conducted from the fifth story to the 40th story at an intervals of 5 stories and based on the finding, energy characteristics of each block type and energy performance depending on the variations in stories were analyzed. It is considered that this would serve as objective data for block type and block story decision of energy performance-based multi-family housing.

During the initial design stage of apartment complex, the photovoltaic(PV) system has been considered as an alternative of renewable energy system and planned to install at the rooftop floor level in general. The electric power generation characteristics can be influenced by the block layout, building orientation and roof top structure because of azimuth angle, tilt angle, and partial shading. This study aims to investigate power generation characteristics of photovoltaic system in apartment buildings by considering the partial shading conditions due to the block layout, building orientation and roof-top structures. For the photovoltaic module arrangement planning in rooftop floor level, shading areas were firstly analyzed due to the adjacent building structure. And the annual and seasonal power generation of PV system were analyzed through the PVsyst simulation results. The results show that shading period at the roof top surface can be increased due to the parapet and water tank. Initial design power capacity can be decreased by considering the daily insolation period and distance between PV modules through the shading simulation. As the number of PV modules decreases, the annual power generation can be decreased. However annual power generation per unit area of PV modules can be increased and performance ratio can be increased above 80%. Also the power generation of PV system can be critically affected by building orientation and the performance ratio can be drastically decreased in east-oriented buildings due to the shading problems caused by adjacent structures at roof top level such as parapet and water tank.

This study examines the impact of residential environmental satisfaction on AIP(Aging in Place), and analyzes how their relationship differs depending on housing characteristic variables (ownership type, housing type, and residential area). For this purpose, as of November to December 2020, a questionnaire analysis was conducted on 373 adult males and females residing in Busan and Gyeongnam. The results of this study are summarized in two ways as follows. First, the higher the satisfaction with the residential environment, the higher the AIP. Second, it was analyzed that the positive relationship between satisfaction with the residential environment and AIP was higher in ownership than in rental cases, and further decreased in detached houses compared to apartment houses. In addition, compared to other regions, metropolitan cities or small and medium-sized cities had a higher positive (+) relationship between satisfaction with the residential environment and AIP. This study will provide important implications for policymaking related to population and urban planning.

10 sites in building development areas were selected and the noise level were measured by the apartment floors of apartment complex. With the fitted regression analysis, the distribution ratio($R^2$) and correction coefficient(r) was 25%(0.5) in the NIER('87) and 7.5%(0.274) in the NIER('99), respectively. The measured values of the noise level on the seventh floor of complex did not show a good agreement with the predicted noise level in the NIER('87, '99) formula. However, the developed formula demonstrated that the measured values were reasonably close to the predicted values, indicating the validity and adequacy of the predicted models with the fitted vs residual analysis in the 95% of confidence interval and 95% of predict interval. The results suggested that application of this development model obtained by the results according to the apartment floor can be improved in road traffic noise.

This study focuses on the regeneration of multi-dwelling residential estates located already in built-up areas. This study focuses on policy measures and surveys of remodeling and analyses the likelihood of remodeling and prospect of it. These major findings were diseased: First, people have changed their propensity about renewing their residences from reconstruction to remodeling. This would account for the likelihood of remodeling and its popularity. Second, unlike the stronger demand for remodeling, over half of people respond express that they are reluctant to pay the costs involved in renewing the public spaces of their apartment complexes. This argues that it would be necessary to review policy measures in other countries. Reducing financial burdens of those who are willing to remodel their residents and to trigger their participations. In addition, the costs should be saved from the outset of constructing new buildings. With the suggestions drawn in this study, the remodeling should be regarded as a considerable measure to renew the residential areas, especially where the area is already built-up and the development density is severely limited.

The residential mobility and the housing choice procedures play a significant role on households welfare. This procedure consists of $\circled1$ Moving motives step, $\circled2$ Housing search step, $\circled3$ Assessment of housing alternative step, $\circled4$ Choice and evaluating after choice step, $\circled5$ Intention to move step. There are linkages with each step. The higher the level of moving motives, the higher the level of housing search efforts. The higher the level of housing search efforts, the higher the level of housing alternative evaluating. The higher the level of housing alternative evaluating, the higher the level of housing satisfaction after they choose a house. The higher the level of housing satisfaction after they choose a house, the lower the level of intention to move. So the whole procedure of housing choice among consumers has a main streaming throughout the steps.
