Much has been made of the changes over time to apartment complexes during the era of rapid development in Korea. This study aimed at analyzing the chronological changes since the 1970s in the laws and regulations governing outdoor space and the residents' appreciation of outdoor space in Daejeon's apartment complexes. The results of this study can be summarized as follows: 1. Similar changes can be found throughout Daejeon's apartment complexes. As time has passed, the building-to-land ratio and the floor-to-land ratio have deceased. The high density trend of apartment complexes has continued until very recently. 2. Although residents' satisfaction with outdoor space around apartments has improved, land for athletic and commercial spaces still remains at its lowest level. Therefore, these kinds of spaces need improvement. 3. Comparing the characteristics of outdoor space in apartment complexes from the 1980s to present indicates that current apartment residents are much more satisfied with the outdoor space, but are conscious of the lack of adequate facilities for the elderly and the handicapped people, and of the hiか density of their apartment complexes. Therefore, these essential consciousness should also be further improved. 4. The residents are gradually becoming aware of changes to the outdoor space that have occurred over time in the apartment complexes, such as in the areas allowed to parking, pedestrians, and athletics. 5. These chronological changes relate to the residents' interest in the changes that have occurred to the outdoor space, especially the convenience of parking, the color of the buildings, the form of the buildings, and the shape of the roofs.

The purpose of this study is to survey the outdoor living space of apartment housing complexes in Daejeon area and to find out the degree of satisfaction, the frequency of use, the preference of facilities and the degree of importance. This study insists that the recognition about the residents' changing demands and interests be considered more important than the aesthetic design. Moreover, it can be proposed as the basic resource which can be used for the social demands. Therefore, various perspectives about the outdoor living space of apartment housing complexes can play an vital role in improving the design process and developing better residential environment.

This study is to analysis the characteristics of electric power consumption of apartments complex in Korea. This study shows the pattern of electric power consumption and correlation of each apartment complex's completion year monthly and timely. With this result, we are able to predict the demand pattern of electricity in a house and make the schedule by demand pattern. It is expected this data is used as reference of electric consumption of Daejeon area to operate the simulation tools to predict the building energy. The yearly data of 10 apartment complexes of 2010 are analyzed. The results of this study are followed. The averaged amount of electricity consumption in winter is higher as summer because of the high capacity of heating equipment. All of the house has electric base load from 0.26kWh to 0.5kWh. The average of the electricity consumption of month is shown as 310.2kWh. A week is seperated, as 4 part such as week, weekend, Saturday and Sunday. During week, the average of timely electricity consumption is shown as 0.426kWh. The Saturday consumption is 0.437kWh. The Sunday is 0.445kWh. The peak electricity consumption in summer and winter is measured. The peak consumption on summer season is 1.389kW on 22th August 64% higher than winter season 0.887kW on 3rd January.

The overall aim of this study is to mitigate urban environmental problems. In particular, to reduce the effects of urban heat island phenomenon which is one of the urban planning perspective. This study focused on the analysis of the relationship between the urban heat island effect and the thermal and wind properties. To do this analysis, water space was virtually made at Yeol_Mae village Apt. Because it is very difficult to set up water space for the existing apartment complexes due to realistic constraints. This study, therefore has a strong sort of guidelines to create water space for newly formed city. It was based on the concept of virtual city through an in-depth analysis on reduction of urban heat island effects for the existing apartment along with creation of water space. To analysis site, Envi-Met Model developed by Michael Bruse was used. The results are as follows. The temperature went from 298.9K to 297.82K and The wind speed went from 1.42m/s to 1.43m/s. The results are slight in this study because creation of water space is planned to a small area of an apartment complex. But if the water space would be applied to a whole city, the mitigation effect of urban heat island would be bigger.

In this study, we analyzed space heating and domestic hot water(DHW) charges from 2017 to 2018 for 151,206 households in 202 apartment complexes built from 1997 to 2016, in order to evaluate the effectiveness of Korea's insulation standards reinforcement. The applied insulation standards were revised three times(in 1987, 2001 and 2010). We used the Anderson-Darling test to review the normality of the space heating and DHW charges. As a result, each p-value was greater than 0.05 and it followed the normal distribution. The annual average space heating charges per unit area of apartments with the 1987 insulation standards were 5,237￦/㎡a in 2017 and 5,328￦/㎡a in 2018. The heating charges with the 2001 standards were 4,827￦/㎡a in 2017 and 4,817￦/㎡a in 2018. Compared to previous standards(1987 standards), heating charges decreased by 7.8% and 9.6%. Also the heating charges with the 2010 standards were 3,683￦/㎡a in 2017 and 3,734￦/㎡a in 2018. Compared to previous standards(2001 standards), heating charges decreased by 24.3% and 21.5%. On the other hand, compared to each previous standards, DHW charges were decreased by 12.2%, 13.6% or increased by 4.6%, 6.9%, which means there's no correlation between insulation standards reinforcement and DHW charges.

This study examined the effects of apartment complex management and residential quality on the residents' residential satisfaction and recommendation intentions. A survey was conducted on the residents of an apartment complex in Doan, Daejeon. Statistical analysis was analyzed using the SPSS 25.0 program. Exploratory factor analysis (EFA) was carried out to verify the validity of the measurement tools for apartment complex management, residential quality, living satisfaction, and recommendation intention. The Cronbach's α coefficient was evaluated to verify the reliability of the measurement tools. Multi-regression analyses were conducted to verify the research hypotheses. As a result, the following main results were derived. First, maintenance factors and living management factors among apartment complex management factors were found to have a significant effect on the residents' residential satisfaction. Second, among the factors of residential quality in apartment complexes, convenience, safety, comfortability, and economy had a significant effect on residential satisfaction. Third, residential satisfaction had a significant effect on the recommendation intention. Overall, the factors of apartment complex management and residential quality affecting residential satisfaction and recommendation intentions were derived.
