Altar architecture is a kind of sacrificial building, mainly formed in altar. Central architecture of Altar architecture is relatively simple. However, various attached building are necessary for worship. Among them, Sinsil which is a place to seal a God's tablet, is very important. The central government of the Joseon Dynasty attempted to define the local sacrificial system and make it customary as a way to strengthen the centralization based on Confucianism. Nonetheless, the altar architecture of the province without detailed regulations, were managed and underwent repairs according to the political situation of the state and local circumstances. Sinsil, which is an important component of the altar architecture, best reflects this situation. Therefore, it was possible to grasp the situation of the altar architecture of the province in the Joseon Dynasty by analyzing the Sinsil through various documents. As a result of analysis, it was divided into six types. In addition, It is also found that there are temporal relation between these six types.

This paper investigates the characteristics of preservation of Korean modern architecture through Western historic preservation theories and philosophies. This research focuses on the Japanese Government-General of Korea (1926-1995) which was built in 1926 and used as the chief administrative building in Seoul (Keijo in Japanese) during the Japanese colonial period (1910-1945). After Korea was liberated from Japanese rule in 1945, this building was used until 1995 for the South Korean National Assembly, the United States Army Military Government in Korea, and the National Museum of South Korea. Although it served a variety of roles, this building was the most controversial case of historic preservation in Korean modern architecture. To analyze the peculiarities and characteristics of Korean modern architecture and its preservation, this research applied Western historic preservation theories, not exclusively from classical historic preservation theories developed by Viollet-le-Duc and John Ruskin, but also from modern historic preservation theories by Theodore H. M. Prudon, Daniel Blunstone, and Frances A. Yates. This cross-cultural and comparative study of historic preservation helps identify Korean modern architecture's characteristics. It can also be a useful reference in finding the origins of Korean modern architectural identity.

Purpose: The purpose of this study is to develop and apply an environmental impact assessment program for apartment building elements, based on the building materials of the LCI DB, which can link the LCA results of building materials and buildings. Method: For this purpose, a framework for building elements was established, and several building material combinations were developed. In addition, the LCA method for quantifying environmental load emissions from the building materials of each site was applied to establish an environmental impact database of the building materials of the LCI DB. Result: An environmental impact assessment program, based on a Microsoft Excel worksheet, was developed for apartment building elements. This program can link the environmental impact assessment of building materials and building units. To validate the program evaluation results that were obtained in this study, a comparative analysis was carried out using the results of existing evaluation methods. The error rate was estimated to be 5% for environmental impact assessment using existing evaluation methods.

In super-tall building construction projects, schedule risk factors which vertically change and are not found in the low and middle-rise building construction influence duration of a project by vertical attribute; and it makes hard to estimate activity or overall duration of a construction project. However, the existing duration estimating methods, that are based on quantity and productivity assuming activities of the same work item have the same risk and duration regardless of operation space, are not able to consider the schedule risk factors which change by the altitude of operation space. Therefore, in order to advance accuracy of duration estimation of super-tall building projects, the degree of changes of these risk factors according to altitude should be analyzed and incorporated into a duration estimating method. This research proposes a simulation model using Monte Carlo method for estimating activity duration incorporating schedule risk factors by weather conditions in a super-tall building. The research process is as follows. Firstly, the schedule risk factors in super-tall building are identified through literature and expert reviews, and occurrence of non-working days at high altitude by weather condition is identified as one of the critical schedule risk factors. Secondly, a calculating method of the vertical distributions of the weather factors such as temperature and wind speed is analyzed through literature reviews. Then, a probability distribution of the weather factors is developed using the weather database of the past decade. Thirdly, a simulation model and algorithms for estimating non-working days and duration of each activity is developed using Monte-Carlo method. Finally, sensitivity analysis and a case study are carried out for the validation of the proposed model.

BIPV system that can alternate building envelope by making materials of PV module should be considered in initial design step for applying PV system efficiently in office building. Mean while, area of the building skin also increases as the number of floors increases, but the valid area that can apply BIPV system in effect decreases relatively. Despite of this weak point, installing BIPV system is still being evaluated as the only measure left that can reduce electronic energy consumption in the building. Therefore, the impact on building energy consumption according to the increase of the number of floors when BIPV system is applied in the building was analyzed. And it will be used as basic information for application of BIPV in office building. Conomic about application of BIPV is interpreted to be secured within the 10 story high. Forover the 11 floors, the methods of increasing the contribution ratio produced by BIPV system through the optimization of install angle and increase in install area of south, high efficiency should be considered. The ways to reduce basic load by integrated design with another renewable energy besides BIPV should be found. Later, the study on the total building energy comsumption with PV generation according to the various type of the basic load and ratio of the width and depth will be performed based on this study.

Recently, as a new perspective to view the architecture in relation to global environmental problems, interest in environmental architecture that conforms to the surrounding environment and nature with nature has been expanded as a part of the natural ecosystem, rather than seeing the building as an independent entity. Traditional Korean architecture creates a comfortable indoor environment by appropriately using the natural energy around, ranging from the arrangement of the building and the space composition to the use of detailed materials and to harmonize the artificial architectural environment without harming the natural ecosystem. The purpose of this study is to propose a method to apply the environmental control techniques of traditional buildings to modern buildings. As a research method, the characteristics of Korean traditional buildings according to the climatic characteristics of Korea were recognized through existing literature data and when applied to methods of traditional buildings, ventilation systems, control through eaves, and humidity control using Hanji the effect of energy load control on traditional buildings was analyzed and identified through existing literature. After analyzing the problems of modern architecture, we analyzed the effect of the environmental control system of traditional architecture on modern architecture. Simulation results show that the application of the environmental control system of traditional buildings to modern buildings reduces the cooling and heating load of modern buildings and has an effect on humidity control. This study suggests that quantitative energy saving will be possible if the environmental control techniques of traditional buildings are appropriately applied to modern buildings.

So far we have investigate and analyzed the actual conditions of building maintenance in Korea and compared the building maintenance laws and systems between Korea and other countries. Now, based on the results from such comparison and analysis, this study proposes the following ideas for improvement: 1) As we can learn from domestic and foreign case studies, in the existing built-up areas becoming obsolete, many building owners remodel their buildings illegally in reaction to current economic and social changes. Therefore, for efficient maintenance of buildings, it is required to improve building maintenance systems by formulating information about inspection items, inspectors, supervisors, inspection costs and intervals of reporting results, depending on how large the buildings are and what they are used for. 2) In addition, to ensure the success of a building maintenance system, it is necessary to keep and manage a history of building maintenance thoroughly and introduce a certification program which gives an appropriate grade to maintenance performance and commits the government to expand their public roles and supporting policies, as widely used in some foreign countries. Further, in keep the building maintenance system secure, there should be a nationwide consensus as well as a favorable evaluation from building owners and manager, and all related people.
