Public rental housing is constructed, owned, and managed by the public sector. The public institution for the public rental housing controls the whole building life cycle from the construction to the demolition. The construction company for the house built for sale is strongly interested in the cost for the initial investment, while the public institution is more focused on the maintenance cost for the preservation of the buildings Nevertheless, the maintenance cost of the public rental housing has been only managed as the accounting factor without the systemic research and analysis on the actual condition. This paper shows how expenses are related to the degree of obsolescence and presents the differences of the maintenance costs by the housing area and expenditure trends (vs time) of the maintenance costs, through analyzing time series data of public rental housing maintenance cost. Further, this paper helps understanding the causes of the differences of the maintenance costs by housing areas and characteristics of the expenditure trends. After all, this paper contributes to the improvement of the reliability and the practicality for the Life Cycle Cost modeling and the maintenance cost estimating.

Because of its physical characteristics, earthquake has a great impact on a wide area in a short time, so it needs a resilience based seismic countermeasures to restore the community function. For this reason, in this study, the seismic damages of urban buildings were assessed stochastically by virtual earthquakes using public data information and disaster management program(Ergo-EQ). A geographical map reflecting geological characteristics of the target area was created with the buildings and topographic data in Dalseo-gu, Daegu City. In addition, an integrated database including building characteristics was modified to be linked with the Ergo-EQ program. The seismic damages for the buildings were evaluated through the exceedance probability of four different damage levels. From the damage results, it can be identified not only the seismic damage of each building, but also the major factors affecting earthquake damage.

The purpose of this study is to comprehensively analyze which kind of factors have an effect on the number of users in the public libraries. For this, this study analyzed various factors, such as personnel, collection, budget, event, influenced on the number of their users of 55 public libraries in Seoul. The results of this study indicated that the number of users in the public libraries is influenced by the number of their seat, librarian, the building size and the number of librarian. Besides, the result of multiple regression analysis to verify these regression models was revealed that the factor influenced on the number of users of public libraries is only the number of seat. The result of this study is expected to practically use in establishing the plan to increase the number of their users in public libraries.

As buildings are changing variously from the side of use, efficiency and size, the construction qualities are more importantly recognized. Supervision system was enacted in the Residential Building Law in 1990 and responsibility supervision system in the Construction Engineering Management Law in 1994, respectively. However, recently revised supervision system in 2003 has some limitations: the present problems of appointing supervisor, disposing the supervisors, supervisor's works. Therefore, the aim of this study is to improve the present supervision system for mix-use residential building. By implementing the proposed revised supervision system, it will be able to expect quality improvement, confidence of the owner and the user, development of construction technology, and increase international competitiveness of supervision company.

The purpose of this study is to analysis of convenience facilities for disabled in the municipal buildings. The physically disabled based on comparative analysis of disabilities code in Korea. For this objective, the code and guideline were analysed, and based on the analysis the checklist was developed for field observation. Convenience facilities ought to consider various aspects like size, and spatial composition of facilities, safety factors. and the present conveniences facility regulation. The research was conducted for municipal buildings located in Jeonbuk province. The procedures for research was made to investigate the finding of architectural related code and faculty standards. The results of investigation should be complemented and clarified guidelines in terms of accessibility and convenience which in detail. If the disabled would be convenient to use municipal buildings facilities, there should be no difficulties. As a result, convenience facilities for disabled in the municipal buildings has been improved that the design concept for the disabled person in general architectural planning.

Recently the renewable energy has been used widely and the importance of renewable sources is bigger than before. So the government enforced a law to the public buildings to install the renewable energy facilities. The capacity of facilities is 5% of total construction cost until April 13, 2011. Since then, the government changed the law from 5% of total construction cost to 10% of predicted energy usage because of the practical use of the renewable energy facilities. So, in this study, the comparative analysis is conducted according to the law to the building installed PV system through the EnergyPlus simulation.

The energy used in Korea is strongly dependent on that produced by foreign countries. Accordingly, saving energy is more important than ever, because of the rise of international oil prices and depletion of oil resources. The development of energy efficient buildings is required especially for public buildings in Korea. In this study, the energy use of public buildings is identify. Then, the analysis of energy usage through regional offices in Busan City offers energy performance for public buildings.

The purpose of this research is to analyze the publicity of the private open space of high-rise office buildings in seoul. The contents of this research consist of two main parts. The first part is to classify the personal behavior's characteristics and to investigate the user's satisfaction of the publicity in the private open space through the case study of samples in seoul. The second part is to analyze the correlations between the personal behavior's characteristics and the user's satisfaction of the publicity in the private open space of high-rise office buildings. In conclusion, this research will contribute to establish the planning methods of the private open space of high-rise office buildings and to promote the quality of urban residential environment in Korea.
