Since the 1970's, UNESCO and ICOMOS have adopted or emphasized on the principles of historic preservation. One of them is what to require a repair have not to be repaired beyond the limits of the features and techniques to have been born in those days of establishment. On the premise, this paper is to examine the materials and technique of lime plaster work in order for roof ridge, and for bond paste of stones and bricks in government constructions in the late of Joseon dynasty(17~19c). The result of this examination will come up with a basic conformity in the case of repairing the building established in the late of Joseon dynasty. This paper is carried out for the proper repair and restoration of architectural cultural properties. Construction reports and other documents in those days are examined for the study. Following conclusions have been reached through the study. The components of old plaster mixtures which agglutinate stones each other were quicklime, perilla oil, and paper fiber. The components of old plaster mixtures which point joint of black bricks consisted of slaked lime, perilla oil, paper fiber, and cereal starch. These components were the same as coat surface of roof ridges. In the case of times, one of the following sand, white clay, sap of boiled elm bark was added to these components for the purpose of high efficiency. These materials and techniques which applied to plaster work of those buildings had developed in the process of making royal tombs. But these materials and techniques were quite different from the present.

This study is to comprehend the interior space of the Royal Palace in the 15th Century, the early years of Joseon Dynasty. The subject of this study is limited to the center of the Royal Palace, that is Jeongjeon(正殿, the royal audience chamber) and Haengrang(行廊, which encloses Jeongjeon on four sides and has many rooms). It is very important to understand the usage of the interior space because the architectural space consists of the space unified by the organic function of the interior and the exterior space. But there are few studies on the interior space of Jeongjeon and Haengrang at the Royal Palace. Therefore, the purpose of this study is to understand the interior space of those buildings. The result of this study is following. Haengrang has several uses such as a night duty room, a storehouse, a government office or a banquet hall etc. So the interior spaces were finished with various methods that were suitable for the use of each room, and the material of the floor were the ground, Maru(the wooden floor) or Ondol(the Korean traditional heating system) There were held many kinds of ceremonies in Jeongjeon, and the government officials could not enter the inside of that building and took part in the ceremony on the front court of Jeongjeon, except the men performing the ceremony. But the high ranking officials could enter the inside when King gave a banquet and there, they prostrated themselves before King. They sat down with their legs crossed on the ground floor instead of sitting on a chair. When King held tea ceremony with Chinese envoys in Jeongjeon, they sat on Gyoui(交倚, a kind of armchair). Then, the government officials performing the ceremony in Jeongjeon prostrated himself around the King and the Chinese envoys and others stood around them.

Since the 1970's, UNESCO and ICOMOS have adopted or emphasized on the principles of historic preservation. One of them is what to require a repair should not be repaired beyond the limits of the features and techniques which had been adopted in those days of establishment. On the premise, this paper is to examine the materials and technique of wall plaster work in the government building constructions in the Joseon dynasty. The result of this examination shall come up with a basic conformity in the case of repairing the building established in the late of Joseon dynasty. This paper is carried out for the proper repair and restoration of architectural cultural properties. Construction reports and other documents in those days are examined for the study. Following conclusions have been reached through the study. The materials and technique which applied to wall plaster work in those days were quite different from the present. The technique that was used to wall plaster of government buildings in those days was not a lime wall plaster, but sand coat one. The kinds of material for setting of the sand coat wall plaster had been revised with the change of the times or constructions. The main kinds of material were composed of sand, white clay, paper fiber, and cereal starch. However, the present materials were composed of sand, white clay. Therefore, the present materials and technique which applied to wall plaster work for the repair and restoration of architectural cultural properties have to be revised and corrected.

In 1990s, as the extreme weather events according to the global warming climate change are occurred frequently all around the world and the scale of the damage increases, the developed countries are promoting various policies for reducing greenhouse gas emissions setting the goal of greenhouse gas reduction with the level of State and local government. Especially for the greenhouse gas reduction of buildings and the inducement of eco-friendly design, the green certification system is strengthened with the assessment of energy and greenhouse management, and recently, according to the policy change of climate and energy, the certification system expanded from the buildings to the level of city and district is piloted. So this research is to understand the main contents and the assessment system of domestic green building certification system implemented in March 2013 in response to the policy change of climate and energy and to suggest the basic data for the improvement of present domestic greenhouse certification standard through the analysis of actual certification and the main case analysis of international green certification system. Recently in developed countries, in 1990s, for the reduction of building's greenhouse gas emission and the inducement of eco-friendly design, from the building of LEED, BREEAM, DGNB to the level of city and district such as LEED Neighborhood Development, BREEAM Communities, DGNB Stadtquartiere, the system is expanded and piloted. On the contrary, as for the domestic standard of green building certification system, the distribution ratio according to the assessment items in each category consists of the assessment system based on the buildings, and just the simple adjustment of some items and the improvement of weighted value are performed. Actually, as a result of selecting the 30 districts of apartment housing with the most certification performance by use among the 49 buildings certified by Institute of Land & Housing from December 2014 to July 2016 and analyzing the assessment score, the certification level is determined by the sectors of high distribution like indoor environment and energy not by the ineffective sector of external environment with low distribution so this system has a limitation to perform the practical means for the policy change of climate and energy. Thus for the national green building certification standards, the assessment system in the sector of external environment is to complemented and furthermore, reflecting domestic reality, through the introduction of certification system and the assessment system with the level of city and district, this system should be improved to meet the international certification standard.

As the number of small households (1 to 2 persons per household) in Korea gradually increases, so does the importance of housing supply policies for small households. In response to the increase in small households, the government has been continuously supplying urban housing for these households. Since housing for small households is a sales and rental business similar to apartments and general business facilities, it is important for the building owner to calculate the project's estimated construction duration during the planning stage. Review of literature found a model for estimating the duration of construction of large-scale buildings but not for small-scale buildings such as urban housing for small households. Therefore this study aimed to develop and verify a model for estimating construction duration for urban housing at the planning stage based on multiple regression analysis. Independent variables inputted into the estimation model were building site area, building gross floor area, number of below ground floors, number of above ground floors, number of buildings, and location. The modified coefficient of determination (R_a²) of the model was 0.547. The developed model resulted in a Root Mean Square Error (RMSE) of 171.26 days and a Mean Absolute Percentage Error (MAPE) of 26.53%. The developed estimation model is expected to provide reliable construction duration calculations for small-scale urban residential buildings during the planning stage of a project.

Many countries have carried out various policies about sustainable building to protect the earth against the global warming and environmental pollution. Korea government has also executed the Green Building Certification System. In order to keep the performances of certificated buildings sustainable, the effective building maintenance is quite necessary. Meanwhile, the foreign green building certification systems have considered the building maintenance as one of the most important items to keep the building performance effective. However, Green Building Certification Criteria(GBCC) of Korea has not had the sufficient criteria for the maintenance of green building. Therefore, The purpose of this study is to find direction for the improvement of management categories of Korea Green Building Certification Criteria. For this aim, GBCC was compared with the foreign certification systems such as LEED, BREEAM and CASBEE.

Because energy consumption of the construction part is very high, there is a growing need to introduce environment-friendly buildings. Therefore Green Building Rating System is enacted in Korea. Though environment-friendly factors such as green area affect the apartment housing price, there's no saying whether Green Building Rating System directly affect the apartment housing price. The purpose of this paper is to estimate the impact of Green Building Rating System on an apartment housing price. The analysis result demonstrated that Green Building Rating System don't affect the apartment housing price. This result means that there is a problem with the effectiveness of Green Building Rating System. The government ought to institute incentive program to ctivate the market of environment-friendly building.
