This study was to analyze the architectural characteristics and facade construction of brick masonry auditorium through the Auditorium of Namsan Primary School in 1936. The results of this study were described separately as follows. 1. The auditorium is located away from the school buildings, and its plane is a chamber of rectangle type with an entrance installed on each of the four sides. 2. The external appearance is Renaissance eclectic style, laid red bricks on the lower wall of the window and having a mansard roof. The front and the rear are symmetric with respect to the projected wall at the center. 3. As to the structure of the building, a concrete lower wall was built on the concrete continuous footing, and the brick wall was constructed on the lower wall. The roof is queen post roof truss, and the wall girders were installed on the brick wall. 4. The auditorium has had a number of repairing and maintenance works, which changed the roof and windows outside and the floor, walls, ceiling, etc. inside. 5. The decorative elements of external appearance include lower wall, brick wall, entrances, windows, roof, and dormer windows. The brick wall gives verticality and solidity to the surface of the wall, and the lower wall and wall girders are connected like a cornice of the wall.

Double skin facade(DSF) ventilated by fans consists of a normal external and an internal envelope. In this glass layer, the installed fan replaces an air inlet for the control of air flow through the cavity. The purpose of this paper is to investigate physical theory and to analyze the applicability of fans installed in a DSF. The experiment was conducted in 2 rooms. One room has a DSF with installed fans and the other one has a typical window. The room ventilated through a DSF which fans are installed was always kept warmer than the other room, ventilated directly from the outdoors. The average increase of the supplied air temperature through the DSF ventilated by fans was $6.54^{\circ}C$ at 78CMH, $6.2^{\circ}C$ at 95CMH, and $3.7^{\circ}C$ at 120CMH. As a result, the DSF with installed fans was appropriate for installation in rooms. It supplies outdoor fresh air heated through a cavity and ventilates a constant air volume.

This study derives the characteristics of the private external space planning in multi-family housing through the analysis of the good case built after 2000 in Europe. First, the cases were categorized into block or block perimeter, linear and point type to examine the relationship between the type of building in urban context and the location of private external space. By block or block perimeter and linear type, private external spaces are planned in the inner courtyards or open space between buildings used as common space for residents, inducing communications between neighbors. And the direction of private external space depends on the arrangement of the building mass in urban context. In the classification as point type, there are many cases, where private external spaces are arranged in all directions, connected almost all interior spaces. Second, based on the above results, the planned characteristics of the private external space are derived by dividing it into three categories: intermediated space between inside and outside, intermediate space between private and public /individual and collective space and the identity of the intermediate space. (1) In most cases, direction, size of enclosed area and location of private extern space is designed to fit the surrounding context, so residents can perceive as much of the assets of the surrounding environment as possible, and it can be used as an extended area of living space. In another cases, it is divided into various sub-areas to experience the spatial transition from inside to outside or vice versa. 2) The private external space, which is placed in a courtyard or in a collective open space, is partially enclosed and blocked, allowing interaction with the neighbors without pressure. Along the street, they are designed to allow residents to experience the vitality of the city and to be formative element of the facade, which could confidently reveal the lifestyle and taste of residents. 3) By some of point types, which facade is three-demensional layer as a habitable external space, the private external space is very flexible for use. This intermediate space is composed of diverse spaces for various needs, or it has generous size with positional conditions connected with all interior spaces to be used multi-functional.

미디어파사드는 건물 외벽을 스크린으로 삼아 영상을 투사하는 것이다. 미디어파사드는 도시 공간에서 고도의 시장 경쟁 상황에 지쳐있는 수용자의 문화적 감성을 회복하며, 도시미학으로 발전하였다. 그래서 도시가 주제가 되기도 하고 투사 대상이 되기도 하면서 영상디자인으로 재해석 될 수 있다. 문화적인 면에서의 미디어파사드는 예술적 가능성과 공공성의 강화가 논의되고 있다. 가장 고려해야 할 부분 중의 하나는 건물 또는 투사 대상 주변과 소통되는 미디어가 되어야 한다는 것이다. 2014 광화문 미디어파사드, 2014 세종문화회관 미디어파사드, 2013 남산 미디어파사드 등의 도시경관 미디어파사드를 비교분석 결과 모티브, 컨셉, 스토리, 투사형태 등 네 가지 영상디자인 구성요소를 도출할 수 있었다. 캔버스와 극장 스크린을 박차고 나아가 새로운 기술적 장르로 자리매김 하고 있는 미디어파사드는 앞으로도 한 차원 높은 도시의 상징적 예술행위로서 메시지와 테마 그리고 기술적 진보를 담아내야 한다. 본 논문은 상징적인 도시경관 미디어파사드의 비교분석을 통하여 영상디자인의 구성요소를 도출하고자 하였다.

In recent years, the number of high-rise buildings has been on the rise. As buildings have become larger in scale, significantly different issues related to their construction and maintenance have emerged. In addition, the automation and mechanization of the cleaning work for the curtain wall, one of the most frequently-performed tasks in building maintenance, is required as a fundamental measure. For this reason, a guide-rail type cleaning robot system is emerging as one of the measures in response to external factors, including gust. The major objective of this study is to propose an economic feasibility forecasting model and to apply the a building facade cleaning robot which is now under development.

As residents and building owners demand maintenance that is required to achieve sustainable building performance, efficient building management methods are required. Even though the demand for maintenance systems is increasing, current maintenance work for high-rise buildings mostly uses conventional ropes and gondolas that pose a high risk of accidents and exhibit poor performance and efficiency. Thus, there is an urgent need to develop an automation robot system that can reduce accidents and improve the maintenance efficiency of the conventional high-rise building façade maintenance system. As a preceding work for the development of an automation robot system, this study classified and analyzed the work processes of actual construction sites and proposed basic techniques for the work mechanisms of the robot system by investigating the motions of cleaning workers.

Corner cut, corner chamfered or a building shape change are adopted in the design of tall buildings to achieve aerodynamic superiority as well as response reduction. Kikuchi et.al pointed out that large negative peak external pressures can appear near the inside corner of set-back low rise buildings. It is therefore necessary to pay attention to facade design around steps in building surfaces. Peak wind pressures for corner cut or corner chamfered configurations are given in the AIJ code. However, they cannot be applied where there are many variations of vertical and horizontal steps. There has been no previous systematic research on peak wind pressures around steps in building surfaces. In this study, detailed phenomenon of peak wind pressures around steps in buildings are investigated focusing on vertical and horizontal distances from the building's corner.

Wind tunnel model tests were conducted for a residential apartment block located within the complex terrain of The Hong Kong University of Science and Technology (HKUST). The test building is typical of medium-rise residential buildings in Hong Kong. The model study was conducted using modelling techniques and assumptions that are commonly used to predict design wind loads and pressures for buildings sited in regions of significant topography. Results for the building model with and without the surrounding topography were compared to investigate the effects of far-field and near-field topography on wind characteristics at the test building site and wind-induced external pressure coefficients at key locations on the building facade. The study also compared the wind tunnel test results to topographic multipliers and external pressure coefficients determined from nine international design standards. Differences between the external pressure coefficients stipulated in the various standards will be exacerbated when they are combined with the respective topographic multipliers.
