This study examines the design intent and the construction background of the UNESCO House in Korea planned in the 1950s, with a focus on the initial plans of the House by Kuzosa Architects & Engineers in 1959. To this day, the House has been evaluated as a representative example of an office building in the 1960s, and an early case of introducing curtain walls in Korea. However, only its technical characteristics have been explored with less emphasis on further research data. This study attempts to demonstrate the social and cultural expectations and the demands of the construction of the House by examining the documents produced at the time and the initial plan. This study also highlights the fact that the House was the first project of the architect Pai Ki Hyung to realize high-rise reinforced concrete construction in Seoul's dense center. In the 1950s, the House was planned as a modern building with a complex of various cultural facilities and offices due to the character of activities of the Commission, and the lack of public cultural facilities in Korea. The plan of the Kuzosa Architects & Engineers was selected through a design competition held in 1959. The House was completed in 1967, which took about eight years from planning to completion with design modification in the 1960s. The initial plan submitted before the design modification shows that Pai used the vocabulary and logic of modern architecture and planned the House not as a simple office building but as a complex cultural facility.

G-SEED(Green Standard for Energy and Environmental Design) is the certification system to evaluate environmental friendliness of buildings for the purpose of reducing environmental burden generated from the entire process of buildings, which is classified into 4 grades according to the evaluated score. Green building certification rule regulate to get over green 2nd grade for the public office buildings of $3000m^2$ or more. However, detailed measures on the applied level of each issue to obtain targeted certification grade have not been prepared yet. For each issue, the score distribution and the ratio of score in proportion to credit were analyzed by certification grade for office buildings which get the G-SEED certification. And applied level of issues were presented for each certification grade.

This paper presents a new method for seismic vulnerability assessment of buildings with reference to their operational limit state. The importance of this kind of evaluation arises from the civil protection necessity that some buildings, considered strategic for seismic emergency management, should retain their functionality also after a destructive earthquake. The method is based on the identification of experimental modal parameters from ambient vibrations measurements. The knowledge of the experimental modes allows to perform a linear spectral analysis computing the maximum structural drifts of the building caused by an assigned earthquake. Operational condition is then evaluated by comparing the maximum building drifts with the reference value assigned by the Italian Technical Code for the operational limit state. The uncertainty about the actual building seismic frequencies, typically significantly lower than the ambient ones, is explicitly taken into account through a probabilistic approach that allows to define for the building the Operational Index together with the Operational Probability Curve. The method is validated with experimental seismic data from a permanently monitored public building: by comparing the probabilistic prediction and the building experimental drifts, resulting from three weak earthquakes, the reliability of the method is confirmed. Finally an application of the method to a strategic building in Italy is presented: all the procedure, from ambient vibrations measurement, to seismic input definition, up to the computation of the Operational Probability Curve is illustrated.

The purpose of this study is examine the characteristics of public open space in the office buildings located in urban commercial strip, in terms of its relationships to street, to building, and to order surrounding facilities. Theoretical basis of this research is that public outdoor spaces are to be the intermediate territory set between streets and a buildings. 5 commercial buildings in Seoul are selected as sample cases and they were closely analyzed in a comparative manner. Based on this comparison, several planning guidelines are suggested for the activation of the space, mainly in terms of the location of public open space in relation to street, the design techniques and devises reflecting the purpose of the space, and territorial arrangement and furniture layout, and the patterns of relationship to surrounding space and facilities.

기후변화 문제를 해결하기 위해 세계 각국은 온실가스 감축 의무를 이행하기 위해 노력하고 있다. 건물부문은 국가 온실가스 배출량의 약 25%를 차지하며, 향후 40%까지 증가할 것으로 전망하는 만큼 정부는 에너지 절감 계획에 대한 정책을 수립하여 추진 중이다. 건물부문의 에너지 절감을 위한 정책의 일환으로 녹색건축인증제도 시행을 통해 보다 에너지 절감형 건축물 설계와 시공을 유도하고 있다. 본 연구는 G-SEED 인증 건축물과 비인증 건축물의 에너지 소비량에 영향을 미치는 원인에 대한 분석과 결과를 바탕으로 현행 제도의 실효성과 문제점을 파악하고 향후 G-SEED 제도의 개선 방향에 대해 논의하고자 한다. 이를 위해 서울시에 소재하고 있는 인증 업무시설 135동과 비인증 업무시설 142동을 대상으로 건축물 정보와 에너지 소비량 데이터를 수집하였으며, 분석결과 다음과 같은 결론을 도출하였다. 인증 업무시설은 비인증 업무시설에 비해 연간 50% 이상의 에너지 절감효과가 있는 것으로 나타났다. 계절에 따른 에너지 소비량은 난방 도일과 높은 상관관계가 있는 것으로 나타났다. 사용승인연도가 높을수록 인증 업무시설의 에너지 소비량은 감소하며, 비인증 업무시설은 오히려 증가하는 경향을 보였다. 규모와 인증등급에 따른 에너지 소비량은 상관관계가 미미한 것으로 드러났다. 본 연구는 이상의 분석을 통하여 G-SEED 인증제도 개선을 위한 기초자료로서 의의가 있다. 또한 건축물의 에너지성능 기준이 강화되는 추세를 감안하여, 분야별 점수를 공개적인 자료로 전환하는 것을 제시한다.

As ongoing construction of a new municipal government building leads to the destruction of the interior of the Kyungsung Municipal Government Building(currentlySeoul Metropolitan City Hall) despite its enormous historic value, this study aims to identify the unique features of spatial composition and interior design of the Kyungsung Municipal Government Building, which is widely known as a typical example of public architecture of the 1920s. The primary goal is to perform a systemic arrangement of its interior data and define the modern historic implications of its interior design, thereby laying the foundation for a compilation of the history of modern interior design. From a historical perspective, the Kyungsung Municipal Government Building-an explicit symbol of Japanese colonial supremacy-has served as the administrative hub of a hugecity for 19 years during the Japanese colonial rule and for 64 years following Korea's independence from Japan. From the perspective of architectural history, it also represents modern transitional buildingsin their shift from historicism into modernism, as manifested by its reasonable placement of interior space matching well with topographical form, easy access by citizens, open office space, and, excluding decoration, a simple and non-authoritarian exterior. Its interior design style follows Western historicist architecture, whereasits simple interior decoration embodies expressive characteristics of pragmatic simplicity. Such elements are notably found in the Grand Central Hall, the Municipal Head's Reception Room, and the Grand Conference Room.

This study was to assess the lifetime cancer and non-cancer risk of exposure of worker and user at public facilities in Korea to volatile organic compounds (VOCs). We measured the concentrations of two aldehydes and five VOCs in indoor air at 424 public buildings that 8 kinds of public facilities (70 movie theaters, 86 offices, 86 restaurants, 70 academies, 22 auditoriums, 30 PC-rooms, 30 singing-rooms and 30 bars) all over the country. There were estimated the human exposure dose and risks with averages of the using-time and frequency for facility users and office workers, respectively. Carcinogens (formaldehyde, acetaldehyde, and benzene) were estimated the lifetime excess cancer risks (ECRs). non-carcinogens (toluene, ethylbenzene, xylene, and styrene) were estimated the hazard quotients (HQs). The average ECRs of formaldehyde and benzene for facility worker and user were $1{\times}10^{-3}{\sim}1{\times}10^{-4}\;and\;1{\times}10^{-4}{\sim}1{\times}10^{-5}$ level, respectively, in all facilities. HQs of four non-carcinogens did not exceed 1.0 for all subjects in all facilities. The estimated ECRs for restaurant and auditorium were the highest, and the PC-room and bar were the next higher facilities. Furthermore, people in a smoking facility had the highest cancer risk. Higher ECRs of formaldehyde and benzene were observed in indoor smoking facilities such as restaurant and auditorium. Higher HQs of toluene and xylene were observed at the restaurant and office building.
