Energy efficiency is vital to improve energy security, environmental and social sustainability, and economic performance. Improved energy efficiency also mitigates climate change by lowering greenhouse gas (GHG) emissions. Buildings are the single largest industrial consumer of energy and are therefore key to understanding and analyzing energy consumption patterns and the opportunities for saving energy at the district level in urban environments. This study focused on two representative boroughs in the major metropolitan area of Seoul, South Korea as a case study: Gandong-gu, a typical residential district, and Jung-gu, a typical commercial district. The sources of the energy supplied to the boroughs were determined and consumption patterns in different industry sectors in Seoul used to identify current patterns of energy consumption. The study analyzed the energy consumption patterns for five different building categories and four different sectors in the building using a bottom-up energy modeling approach. Electricity and gas consumption patterns were recorded for different building categories and monthly ambient temperatures in the two boroughs. Finally, a logarithmic equation was developed to describe the correlation between commercial activity and cooling energy intensity in Jung-gu, the commercial district. Based on these results, recommendations are made regarding the current energy consumption patterns at the district level and government energy policies are suggested to reduce energy consumption and, hence, greenhouse gas emissions, in both commercial and residential buildings.

A simple analysis of atmospheric sulfur dioxide($SO_2$) pollution in industrial region was investigated using badge type passive samplers. It were set up in 76 locations and the $SO_2$ distribution evaluated along the boundary of land use type. It changed considerably both monthly and seasonally. Soil samples were also collected in 120 locations to investigate influence of sulfur dioxide pollution on soil and heavy metal distribution in the study area, where the sulfur dioxide pollutants from industrial area could affect the soil environment of near residential and green areas. The relationship between the $SO_2$ concentrations in the atmosphere and heavy metal(Cu, Pb) concentrations in the soil were analyzed, by using the correlation coefficient values and the results were 0.17 and 0.08 in industrial area. And this study indicated that the atmospheric pollution in industrial region affect the level of the soil pollution adjacent to the residential and green area. The study result may be used to define correlativity for establishing an exposure index. It will subsequently be used for a more precise assessment measuring the exposure of plants and inhabitants, for the purposes of a study en effects on health.

The purpose of this study was to investigate the characteristics of leisure behavior and preference for leisure environment of the five-day workweek company employees according to gender for developing leisure facilities in residential community planning. The questionnaire survey was used. The subjects of questionnaire survey were 338 staffs of 7 companies, who were living in apartment complex. The questionnaire consisted of way of life about leisure, leisure necessity, actual condition and need of leisure spaces, and leisure satisfaction. Frequency, percentage, and mean, ${\chi}2-test$, t-test, and factor analysis were used for data analysis. The major results were as follows. 1) In terms of leisure time in weekend, the available leisure time distribution, and leisure cost, there were not difference between men and women. 2) After five-day workweek, the men and women showed to increase their leisure activities and to engage in diverse forms of leisure. Also, they showed an increased desired ratios in participating in each leisure activities. 3) Leisure was necessary to strengthen the unity of family and cultivate the sentiment. 4) Even though current main area for leisure were in their house, men were likely to change them from in the house to around and near their house. And they needed leisure facilities which was closer to their house. 5) The degree of satisfaction of leisure facilities in residential environment was low and there were not difference between men and women. This result implicated to improve and develope leisure space and facilities near the residental environment for promoting leisure behavior of both women and men. In particular it is necessity to create the good atmosphere of leisure facilities for women.

Housing Re-Development business is to improve the environment of old residential area and secure insufficient infrastructure facilities for the public, and to provide housing of fine quality for the individuals and it is taken as an opportunity for the individuals to be able to increase their property. However, it is true that the benefits from the redevelopment has not offered to the original dwellers who has lived there for a long time. This research studies the related systems of the Rental House Redevelopment Supply Service and is to present the schema to raise resettlement rate through the investment on the rate of tenants who chose the rental house and their specific characters. This study is to present the reform measures about the following 3 problems, on the basis of prior theoretical studies which deals with the common factors having low rate to move in the rental house of the tenants. (1) Physical side, the problem of supply structure, which is not appropriate Housing Supply Structure, (2) Psychological side, the problem of socially excluded rental house residents (3) Economical side, low re-settlement rate of tenants caused from the unreasonableness of the estimated rental value. This study presents that the compulsory rental housing supply rate should be changed to the gross area not from the number of households, and the supply of rental houses should correspond to the household size of tenants through prior demand survey. Secondly, it proposes the housing complex layout for intermixing to solve the social problems to allow a housing for sale and rental houses mixing in a building. And it proposes that the rental value should be calculated considering the neighboring value and in the long run, it should be calculated considering the tenants' income instead construction cost estimate. Also, it should be arranged to provide an opportunity to create income through resident welfare center improvement and provide self-sufficiency functions leading residents to participate in the residential area's repairing and maintenances.

In order to examine theoretical underpinnings of preference for built forms, 129 subjects are asked to rate a series of 9 slides of residential houses depicting a wide range of architectural styles on a 5 point scale, for coherence, complexity, excitement, familiarity, and natural harmony, respectively. Based on Lee's (2002a, 2002b) two previous studies addressing the issue of aesthetic beauty evaluation for man-made creatures (e.g., residential housing scenes), this study summarizes several meaningful findings. As reported by all the subjects, first, both "desire to visit" and "desire to live in" turned out to be a good predictor of preference as the two measures are highly correlated in statistically significant levels (99.9%). People who desire to visit a spot are more likely to desire to live in it. Second, Pearson's correlations showed that coherence is the opposite end of complexity. The more likely a housing setting is hanging together, the less likely it looks to be complex. Overall, though, it is not clear that the two variables work directly in that way, as weighted on preference ratings. That is, coherence and complexity are likely to be totally two independent systems that affect the ratings of preference. Third, both excitement and environmental sensitivity (e.g., harmony of a house with its surrounding nature) most highly account for the preference for various housing scenes, while familiarity has only a little effect on preference ratings. Possibly, people like or dislike a visual thing, no matter how much they are familiar with it. Finally, this study suggested that design professionals could communicate effectively with their clients if sets of visual standards as an appropriate communication tool for better design are properly established.

This paper presents the results of a case study of a dispute for the damage of the right to sunshine between B and W Apartment Complex in the N city. Recently a number of disputes for the right to sunshine increase in urban areas because the residents' demand for pleasant residential environment is getting stronger. In particular, problems related to sunshine, which were not recognized during the construction, have come up to the surface over time as people's concern over residential environment is growing. According to a recent interpretation of the right to sunshine in urban areas, moreover, there have been a series of legal decisions starting that damage of the right to sunshine to neighboring apartments must be indemnified for even if the violating apartment was designed and constructed legitimately according to relevant construction laws applied when the building was constructed. Thus this study examined the effects and the scope of damage on the right to sunshine through a case study in order to provide basic materials necessary to rope with related civil affairs.

The purpose of this study is to evaluate a method for the measurement of N,N-Dimethylformamide (DMF) and to apply the method to the ambient air samples. For the determination of DMF together with other general VOCs (e.g., benzene, toluene, and xylenes), adsorption sampling and thermal desorption with GC/MS was used in this study. The sampling and analytical approaches tested in this study showed a good repeatability and linearity with lower detection limits of less than 0.35 ppb. Field measurements were carried out at three industrial sites (Daegu-Seongseo, Siwha and Banwall industrial complexes) and one residential site in Daegu city during a period from October 2006 to November 2008. DMF was detected in 71.8% of the total samples from the Seongseo industrial complex, well known for textile industry. In contrast, DMF was detected in only 20.4% and 12.9% of all the samples from the other two sites in Banwall and Siwha industrial complexes, respectively. This implies that sources of DMF should be strongly associated with textile industry. The mean concentration of DMF also appeared to be the highest in Seongseo site (5.95 ppb), followed by a residential site in Daegu (3.28 ppb), Banwall (0.88 ppb) and Siwha (0.55 ppb). In this study, we demonstrated the environmental significance of DMF in urban ambient air. To our knowledge, the DMF measurement introduced in this paper is the first case of an official report in Korea.

Most of the Korean apartment complexes are considered as gated communities having characteristics such as self-sufficiency in service provision, self-governance and exclusiveness. Today the exclusionary features of apartment complexes are reinforced by a new practice of erecting gates against pedestrians in addition to the existing walls without considering implication of the practice over neighborhoods. Three groups of residents, those who live in low-rise residential areas without walls, apartment complexes with walls and apartment complexes with walls and gates were surveyed to measure the impact of the new exclusionary practice of gated communities on social sustainability of neighborhoods. Gates turn out to improve social sustainability indicators related to life quality but lower social cohesion of neighborhoods by lowering inclusiveness indicator considerably. The new apartment complexes with increased exclusiveness shake the established order of co-existence between low-rise residential areas and apartment complexes and strengthen spatial and social segregation within neighborhoods.

It is important for urban planners and policy makers to understand complex, diverse urban demands and social structure, but this is not easy due to lack of data that represents the dynamics of residents at micro-geographical level. This paper explores how to create population data at at a micro-level by allocating population data to building. It attempted to allocate population data stored in a grid layer (100 meters by 100 meters) into a building footprint layer that represents the appearance of physical buildings. For the allocation, this paper describes a systemic approach that classifies grid cells into five prototypical patterns based on the composition of residential building types in a grid cell. This approach enhances allocation accuracy by accommodating heterogeneity of urban space rather than relying on the assumption of uniform spatial homogeneity of populations within an aerial unit. Unlike the methods that disaggregate population data to the parcel, this approach is more applicable to Asian cities where large multifamily residential parcels are common. However, it should be noted that this paper does not demonstrate the validity of the allocated population since there is a lack of the actual data available to be compared with the current estimated population. In the case of water and electricity, the data is already attached to an individual address, and hence, it can be considered to the purpose of the validation for the allocation. By doing so, it will be possible to identify innovative methods that create a population distribution dataset representing the comprehensive and dynamic nature of the population at the micro geographical level.

This thesis attempted to generate ideal tea culture space that connects environment and culture. Therefore, this examines: First, history of tea and the characteristics of tea culture space from Gochosun to modern times was reviewed Second, psychological factors (spirit of tea) of Korea tea culture space were reviewed. Third, the connection between the concept of tea culture space and Human Ecosystem Model by was analyzed. Also, this thesis examined how the culture of ecosystem and why tea culture space is needed. because tea includes varieties of ingredients for protecting environmental pollution. Finally, tea culture spaces were reviewed each region during Chosun dynasty, and tea culture space of recent tea users. In order to study tea culture space, complex residential area and single residential areas were compared. The useful of tea culture space as a ecological space was also examined. To achieve the purpose of this study, related literatures were reviewed, and investigations of museums and a survey on modern living space were also conducted. The results show that the space of our tea culture were affected by nature worshipping of Gochosun, Buddhism of Koryo, and Confusianism of Chosun with 'Pungryu', the idea that enjoys nature, thereby applying environment-friendly ecological beauty to their living space and life. The cultyral space in Korea is composed of natural environment such as mountain, sea, rock, or trees and artificial environment such as pond or pavilion. In the future, oriental culture with metaphysical value will lead the world culture, and especially, tea culture would play an important role regardless of nationality, race, religion, and ideology. Therefore, establishing a tea culture space in a living space would be the fundamental methods that would be able to settle down such tea life into our daily life. Our attempts to create ecological tea culture space as a integrated cultural space of natural, artificial, and human behavioral environment will contribute to enhance our quality of life.
