The main purpose of this research is to understand how the problems, which existing letter-shape houses have, are solved in Unjoru which is one of the letter-shape houses. Furthermore, there is the secondary purpose which is to realize the architectural characteristics of Unjoru through the process from the composition of rooms and buildings to the method of structure and roof formation. This research was approached in terms of architectural design, and as the result, the problems of the existing letter-shape houses was resolved by literally converting the shape of outdoor space to 品-shape form. Moreover through the result, it was recognized that the 占-Shape plan was flexible in responding to the demand of the times, such as the order of precedency within men and women and each generation. In addition to the previous results, it was confirmed that the location of major rooms was also decided by considering the interrelationship with natural environment of surrounding area. Also, in the whole proportion of building's plan, each building, such as ㄷ-shape Anchae and big-sized and middle-sized Sarangchae having 丁-shape form, and major rooms in the each building have proportion system such as 1:1, 3:4, $1:\sqrt{2}$, and 3:5 as aesthetic numerical value. Finally, it was understood that the architectural intention had double-sided characters, one side was authority and dignity in the aspect of shape and another side was practicality in aspect of inner housing life.

그리스의 극장은 인공적으로 구축된 최초의 극장이며, 로마의 극장은 그리스의 것을 모방하여 독창적 형태로 발전시킨 것으로 이 두 극장의 형태와 관습이 현대에 이르기까지 많은 영향을 끼치고 있다. 두 극장을 비교해 볼 때 다음과 같은 차이점을 발견할 수 있다. 극장이 설립된 목적과 기능 면에서 볼 때 그리스 극장은 종교적 목적에서 기인한 것이나 로마의 극장은 오락적 목적에서 기인한 것이다. 극장의 형태 면에서 볼 때 그리스 극장은 완전 노천 구조로 위엄 있고 웅장한 것이었으나 로마의 극장은 무대에 지붕을 포함하고 있었으며 화려하고 장식적인 것이었다. 극장의 성격 면에서 볼 때 그리스 극장은 민주적이었으나 로마의 극장은 계급적이었다. 그리스, 로마극장은 그 시대의 사회적 특성 및 연극적 특성에 따라 서로 구별되고 있지만 그리스 로마 고전극이 유럽 연극에 있어 하나의 원천이 되고 있는 것처럼 이 두 극장도 역시 하나가 되어 현대 극장의 원천이 되고 있다.

Renzo Piano was first introduced to us when he got together with Richard Rogers and won the Grand Prize on Center George Pompidou Competition in Paris. Since then, he designed number of world renowned museum architecture such as Menil Collection & Museum, The Cy Twombly Gallery, Beyeler Foundation Museum, and most recently the New Pavilion of High Museum of Art. His museum design, in particular, showed very consistent feature which is differentiating the 'Served Space(exhibition area) and the Servant Space(service core or mechanical system area)'. In addition, the way he treats natural light as a special feature within his museum space was nicely done and it is remarkable both in design and engineering side; he always designed a very unique roof structure system to give life and to simulate emotion of light within the space. These are just a few points of his special design characteristics which differentiate him from the rest of the architect working today. While interested by works of Renzo Piano, we found that his work had very close relationship to Louis I. Kahn's design. Specially the way Renzo Piano differentiating serving and servant space and the way he treating natural light. Therefore, the purpose of study is focused on providing typology of museum exhibition organization as well as finding evidence of Louis I. Kahn's influence and concept he has shown in his museum projects through actual site visits and reference research. The method of research was as the following; first to find typology and its characteristics of exhibition space organization of all Renzo Piano's museum projects. Secondly to distinguish projects which show 'differentiated servant and served space'. As the result of this study, it was clear that Renzo Piano had influence of Louis I. Kahn on adopting 'Servant and Served Space' concept. But the research concluded with the facts to approve the uniqueness of Renzo Piane's design concept.

The purpose of this study is to examine the characteristics of space design appearing in facade and interior composition factors of buildings in the colonial period in Indonesia. Research method is a field study, and subjects of the study is 14 buildings built in the colonial period located in Jakarta. The research result is as follows. First, Facade is divided into C type (colonial style), CT type (colonial style + traditional style), CA type (colonial style + art deco style), and CTA type (colonial style + traditional style + art deco style). Among them, CT type which shows both a colonial style and traditional style accounts for the most. As for Java traditional style mainly shows Joglo roof style and bratticing decoration on top of gates, and the colonial style presents both an Amsterdam canal housing style such as narrow Facade and unusual Gable, and a classical style such as pediment, entablature, and columns. Second, interior space is divided into C type (colonial style), CT type (colonial style + Indonesian traditional style), A type (art deco style), and CA type (colonial style + art deco style). Among them, CT type was also accounted for the most. Selected traditional style is a shape of bratticing decoration on top of gates and a shape of tenon of Joglo housing structure. Colonial style showed classical style such as exposed crossbeams, columns, and pilasters, and as for unique decoration, there are Ancona decoration and Delft tile decoration. On one hand, art deco style used typical art deco factors such as contrast of various materials and complementary color or golden color use as well as zigzag or vertical lines and geometric ornament by combining with colonial style or traditional style. It is expected that such research result will be a practical reference data when Korean construction companies or interior design companies advance Indonesia.

With the increasing demands of 3D spatial information in urban environment, the importance of point clouds generation techniques have been increased. In particular, for as-built BIM, the point clouds with the high accuracy and density is required to describe the detail information of building components. Since the terrestrial LiDAR has high performance in terms of accuracy and point density, it has been widely used for as-built 3D modelling. However, the high cost of devices is obstacle for general uses, and the image-based 3D reconstruction technique is being a new attraction as an alternative solution. This paper compares the image-based 3D reconstruction technique and the terrestrial LiDAR in point of establishing the as-built BIM of outdoor structures. The point clouds generated from the image-based 3D reconstruction technique could roughly present the 3D shape of a building, but could not precisely express detail information, such as windows, doors and a roof of building. There were 13.2~28.9 cm of RMSE between the terrestrial LiDAR scanning data and the point clouds, which generated from smartphone and DSLR camera images. In conclusion, the results demonstrate that the image-based 3D reconstruction can be used in drawing building footprint and wireframe, and the terrestrial LiDAR is suitable for detail 3D outdoor modeling.

The greenhouse type metal structures are increasingly used in modern construction of livestock farms because they are less laborious to construct and they provide a more favorable microclimate for the growth of animals compared to conventional livestock structures. A key stress factor for metal structures is the wind. The external pressure coefficient ($c_{pe}$) is used for the calculation of the wind effect on the structures. A high pressure coefficient value leads to an increase of the construction weight and subsequently to an increase in the construction cost. The EC1 in conjunction with EN 13031-1:2001, which is specialized for greenhouses, gives values for this coefficient. This value must satisfy two requirements: the safety of the structure and a reduced construction cost. In this paper, the Navier - Stokes and continuity equations are solved numerically with the finite element method (Galerkin Method) in order to simulate the two dimensional, incompressible, viscous air flow over the vaulted roofs of single span and twin-span with eaves livestock greenhouses' structures, with a height of 4.5 meters and with length of span of 9.6 and 14 m. The simulation was carried out in a wind tunnel. The numerical results of pressure coefficients, as well as, the distribution of them are presented and compared with data from Eurocodes for wind actions (EC1, EN 13031-1:2001). The results of the numerical experiment were close to the values given by the Eurocodes mainly on the leeward area of the roof while on the windward area a further segmentation is suggested.

Unlike Urban building, horticultural facilities has a lot of heat loss through plastic or glass covering material which could be much influential to growing plant and consuming energy for heating greenhouse. In many cases, heat loss from a break of cover, a gap of joint sealing, the entrance to greenhouse and windows for ventilation are the main factors considered in calculating the heating load for horticultural facilities. however the normal observation through human eye and digital camera could not recognize where the heat loss occurred. but the infrared thermal image camera with detecting thermal difference could be very effective for noticing heat loss by analyzing infrared thermal image. In this study, greenhouse structure, covering material, internal and external provisions for Horticultural facilities were surveyed in different sites and Infrared thermal camera shooting and image analysis were performed for auditing heat loss from cultivation facilities The results from this study were that unexpected heat loss had been noticed in 7 representative cases of greenhouse such as side wall covered with single or double plastic, and the joint of horizontal thermal curtain, roof without horizontal thermal curtain, entrance to greenhouse, windows for ventilation. the most important factors for keeping heat energy were whether the horizontal thermal curtain with multifold thermal material was installed or not. The internal or external covering using multifold thermal curtain proved to be the most effective ways to keep heat energy from losing through heat transmission, heat radiation. from inside to outside the horticultural facilities.

Recently, high-rise apartment is being briskly built but there are problems such as lack of ventilation, stack effect and much energy consumption. Therefore It is recommended to develop a Small Wind Power System Combined Ventilator as a solution to solve these problems. The purpose of this study is to provide basis for Small Wind Power System Combined Ventilator in super high-rise apartment. This study conducted CFD simulation (Star-CCM) according to the shape of structures, building height and distance of two structures to identify the effect of wind speed increase when the structure is installed. As a result, pyramidal type was best suited for increase of wind speed. The best place was the front of the roof to main wind direction, and the best building height was 200m rather than 300m. If two or more small wind turbines combined ventilator are installed closely, vertical position to main wind direction is recommended. Horizontal position must necessarily be avoided, but height difference between two blades more than 3m showed good performance.
