The methods used in this study included investigation of media facades used for landmarks in downtown areas in previous studies, visits to these areas, and recording of media facades. The changes in the colors or the size of buildings were analyzed among the recorded cases and 12 of these cases were selected for further study. The sensibility preference of the media facades was evaluated by sorting the 12 kinds of media facades, and providing them as materials to a group of 60 participants (40 undergraduate and 20 graduate students majoring in architecture and design) consisting of an equal proportion of males and females. This study addressed the following four_stage questions: 1) Five questions of recognition evaluation about media facades and the cognitive evaluation items of emotional vocabulary and color preference in each research case; 2) sensibility preference items regarding the media facade color design; and 3) design evaluation items of the media facades; 4) Video clips and still images were recorded from a middle distance at 7p.m to 11p.m. in central New York, Singapore, Seoul, and Beijing. The participants looked at the changes in colors through the video clips in each case and evaluated their preferences through 23 pairs of emotional vocabulary items using system dynamics. Construction of an emotional vocabulary followed, based on previous studies about media facades and color design. To evaluate the sensibility preference and the perceived representative colors of the media facade, this study suggests new emotional responses that depended on the color emotional vocabulary of light in the LED lighting technical evaluation methodology. A media facade with a moving change of colors, unlike a fixed landscape color design, suggests a new communication method based on architectural factors. New architectural color coordination can be presented for urban landscapes at night. Designs that factor in the pedestrians' emotional vocabulary or preference should take precedence over the use of high luminance and various colors.

In case of general residential house, photovoltaic can be installed at roof, wall, and any other places. But, in case of apartment building, there has not enough roof space to install photovoltaic panels to supply enough electricity. Actually, apartment building roof and facade wall (exclude the balcony window space) is not enough space to produce and supply the electricity to residents by installing PV panel. Generally, the space of facade balcony with windows in facade wall at apartment building occupied about $70{\sim}80%$, in all facade space. So, if we could use the balcony and windows space in facade as PV to generating electricity, there could contribute the energy saying. But, PV cell is opacify. So if it installed at front window area in apartment building, residents may have displeasure for that opacity character. But the other hand, residents are not always in house especially in day time that is exactly good time for generating electricity by PV. If we can use PV at the facade balcony with window without collusion of resident's displeasure, there have good attraction to using sustainable energy. Hence, this study suggests the design of facade balcony window style PV by considering resident's living pattern in apartment building. The methods of this study are as follows. At first, this study surveyed to the residents about residential time in their home and asked user demand by Delphi survey. At second, this study designed balcony open style PV system which oriented to the user demand. At third, this study tests designed result performance by computer simulation that compared design result with old design. As a result, For the purpose of satisfying the resident demand, there designed sliding window style which slide the several door systems to the one side. That would be make balcony absolute open scenery to the residents. Hence, the designed system performance results were as follows. When we compare the small apartment and large apartment, smaller one has good performance than larger one. Because resident's residential time characteristic. And that has more good electronic performance than vertical style that is similar to roof style.

The objective of this study is to investigate the effect of building integrated PV application method on power generation. PV modules were integrated to a hypothetical apartment building facade in Seoul, Korea. Three different design options of PV panel mounted on exterior wall were developed for the analysis of cooling effects through ventilation. Numerical simulations using TRNSYS coupled with COMIS were executed to evaluate the design options. Their facade configurations are such as vertically installed PV panels with or without air gap between PV rear surface and exterior wall surface, and the tilted PV panels attached to the exterior wall at an angle of to the horizontal. Parametric results show that there is little difference regardless of the air 9ap width between PV rear surface and exterior wall surface. Special strategies which could effectively cool a PV panel to increase the electric power are required if we prefer to a vertical facade configuration in a building integrated PV installation. Consequently, it is expected that there is no reason for architect to install vertically PV panels with air gap unless active strategies are considered.

This study is to examine architectural designers' views on the correlations between components and contextual principle of the roadside building facade with the roadside building facade on the border of Asian Culture Center in Gwangju which is expected to undergo a great change by public policies. For setting direction of the roadside building management at the region examined, height of facade, advertisement/signboard, security of continuity through surface pattern management, nodes building, array of height by story, awning/arcade and locality of advertisement/signboard should be induced to design with locality and consideration of local characteristics with silhouette, window and external colors is needed for discrimination from other cities. Regarding the realization method important thing was found that the planning and implementation of architectural design guidelines, architectural aesthetics of the pre-hearing enhancement, active citizen participation, and then additional landscape screening system, incentive schemes, landscape designation of landscape zone was found to be a major realization system.

Purpose : Improvement of indoor thermal comfort and reduction of the energy consumption in building can be obtained by applying a double skin facade system. In order to achieve effectively this purpose, design team would have to perform easy and appropriate performance analysis for making better design decision during the design process. Method : This paper focus on the natural ventilation performance of a multi-story type double skin facade with main causes which are pressure difference according to the wind and temperature difference between indoor and outdoor (Buoyancy Effect). Using this main causes, the natural ventilation ratio of wind effect-to-buoyancy effect in cavity of multi-story type double skin facade were analyzed through the performance analysis results of CFD (Computational Fluid Dynamics) simulation. Result : When the wind velocity was 2m/s, the ventilation rate in the cavity was highest. If wind velocity was slower than 2m/s wind velocity, buoyancy effect has more influence on the ventilation rate in the cavity, and if wind velocity was faster than 2m/s wind velocity, wind effect has more influence on the ventilation rate in the cavity.

The purpose of this study was to investigate the influential factors of space marketing, and then to empirically analyze how they were reflected on the facade elements of sports stores. In order to achieve such a purpose, the research was firstly based on the perspective of space marketing to extract various features into 4 types of factors, namely sensuous factors, differentiated external appearance factors, image-associating factors and story-creating factors. Secondly, this study extracted the elements of facade design for sports stores including architectural elements, visual elements and display elements. Thirdly, it clarified the correlation of the influential factors of space marketing with the external space elements of sports stores. Fourthly, the qualitative analysis method was applied to analyze eight selected cases in Busan and eight selected cases in Fukuoka, Japan in order to explore the various different methods of expression of facade design. Lastly, the study found that the stores in Busan mostly take advantage of contrasting effects to deliver a strong visual impression to customers in the sensuous factors. Besides, the facade shapes in Busan were designed to be straight in order to enhance the main doors with its distinguished formative features to maximize the effective expression of the differentiated external factors, along with other expression methods of the image associating and story creating factors. This was done to associate with the brand identity in comparison with the stores in Fukuoka.

Korean commercial architecture is based on two distinctive characteristics of western modern architecture: grid frame structure and free facade. However, the original facade of the building disappears as numbers of commercial advertisements and signboards representing inner programs cover up the original facade. This is a unique feature of commercial architecture in Korea which I would call the surface phenomena of Korean commercial architecture. Common criticism on this type of building is that too many and too big signboards infringe upon the original pure facade of the architecture. Underlying assumption here is that signboards and commercial ads are inessential and decorative elements simply attached to the original pure facade of modern architecture. However, in this paper, I argue that commercial decorations is an essential aspect of korean commercial architecture rather than an inessential decorative element attached later to the essential facade of architecture and that it reflects the historical specificity of cultural and architectural modernity of Korea And thus, the surface phenomena of Korean commercial architecture should not be judged based upon the aesthetic paradigms of either western modern or postmodern architecture. Rather, it can be argued that surface phenomena of Korean commercial architecture is a reflection of a modernity beyond the paradigm of western modernism and postmodernism. The agenda of Korean commercial architecture is then not simply to restrict or to control signboards on the building facades with the intention to clean up facade of the building but rather to integrate the signs and commercial ads with the structure of architectural surface.

Recently a number of media facade buildings making beautiful cityscape landmark has been increased in Seoul. However, indiscreet adaptation of media facade cause problems such as light pollution and poor city image. This paper was to investigate luminous characteristics of media facade building. Five representative media facade buildings in Seoul have been selected. The CS-100 and ProMetric-1400 were used to measure the luminance and color temperature of the facades. The measurement points were located at the opposite spot of the building. The results showed that maximum media facade luminance of such buildings exceed Seoul design guideline. Also, color temperature with over 5,500[K] that exceed the design guideline were mostly used in all the facades.

The purpose of this study is to derive the design characteristics of the pattern, which can effectively support the building facade design and to analyze the correlation of their characteristics. This paper deals with five different design patterns suggested by Ben Pell. They are the applied pattern, perforated pattern, layered pattern, casting pattern, and tiled pattern. This paper analyzes the design characteristics of the applied pattern, which shows the highest point in the previous survey. The 'continuous' has a high emotional correlation. The high correlation with the emotional word 'continuous' and 'regular' was derived. The final emotional design characteristic is 'continuous-discontinuous', and 'irregular-regular'. and these emotional words can be summarized as the relatively highest correlation. In this paper, it is worth analyzing design characteristics of building facade by a support of digital technology and discussing utilization of design characteristics derived.
