  • This study is an attempt to understand the floor-specific characteristics of facade road traffic noise in apartment buildings. For this purpose, it sampled a total of seven roadside apartment building complexes: three with no soundproof bar barrier installed at roadside, one with a forest buffer zone, one with a sound-absorbing hill, and two with soundproof barriers. The measured noise level was highest on the 5th floor of apartment buildings with no soundproof barrier, and the upper stories from the 5th floor showed lower-noise measurements in order. For apartment buildings with soundproof barriers, however, the noise level was lower on the 10th floor than the 5th floor. Two apartment building groups--one with a sound-absorbing hill and the other with no soundproof barrier--showed similar measurement results in the floor-specific characteristics of facade road traffic noise. This suggests that such installations have little sound insulation effect. In the apartment building complex with a forest buffer zone around it, a slight sound insulation effect was measured on the lower floors of the buildings.

  • The aim of this study is to estimate the noise exposure of roadside apartment complex according to the characteristics of apartment complex. The facade noise level of residential buildings and the ground noise level inside apartment complexes were predicted and analyzed using noise mapping based on a computerized noise model. In addition, the correlation analysis between these noise levels and the characteristics of apartment complex such as traffic volume, building coverage, the number of adjacent roads, etc. was done in a total of 21 apartment complexes. The results showed that building facade noise level and ground noise level were positively correlated with traffic volume (correlation coefficient, r=0.616~0.623) and the number of adjacent roads (r=0.340~0.496). On the other hand, they were negatively correlated with building coverage (r=-0.413~-0.477) and complex area per the number of roads (r=-0.478~-0.615).

  • The purpose of this study is to examine the characteristics by design component elements of the facade in elementary school buildings after the 7th educational curriculum. This study choose twenty five elementary school as the subjects of the study. And among many elevations of building, an elevation that is alongside of the schoolyard is chosen because this elevation has the highest visual influence on passers-by. To begin with, this elevation is divided into the roof and the surface of a wall, The roof is divided into roof styles, existence of roof and materials. The surface of a wall is divided into design principles(balance, contrast, rhythm), the formal organization(basic elements and form, and transformation of form), the ornamental composition, materials and colors. The results of the research are summarized as follows: First of all, motifs of classical architecture were well expressed in this period and postmodern tendency had been shown until 2005. After Build Transfer Lease(BTL), however, tendency of classical architecture, contrast by the size of the form and base element by point disappeared. Instead, asymmetrical and flat tendency is expressed. Also, emphasized design of the building elevation appear by basic colors of Munsell, not motifs of classical architecture.

  • Green facade has a significant impact on building's energy performance by controlling the absorption of solar radiation and improving outdoor thermal comfort through shading and evapotranspiration. In particular, since high-density building does not enough green space, green facade, and rooftop greening using artificial ground plants are highly utilized. However, the level of cooling effect according to plant traits and irrigation control is different. Therefore, in this study, the cooling effect analyzed for a total of 4 cases by controlling the irrigation condition based on hedera and spurge. Although hedera under sufficient water had the highest cooling effect(-2℃~-4℃), had the lowest cooling effect under non-irrigation(+1.1℃~+4.4℃). In addition, hedera under sufficient water had cooling effect than hedera under non-irrigation(-1℃~-8.1℃) and in the case of spurge, it had cooling effect(-0.3℃~-7.8℃) more than non-irrigation. As a result of measuring the amount of transpiration according to the light intensity (PAR) and carbon dioxide concentration conditions, transpiration of hedera was higher than the spurge (respectively 0.63204mmolm-2s-1, 0.674367mmolm-2s-1). The difference in the cooling effect of the green facade under irrigation condition was significant. But the potential cooling effect of green facade according to plants species was different. Therefore, in order to maximize and continuously provide the cooling effect of green facade in urban areas, it is necessary to consider the characteristics of plants and the control of water supply through the irrigation system.

  • This study is aimed to investigate the characteristics of the elevations in the contemporary multi-family residential buildings in Paris. The survey was performed by studying 30 buildings which had won the multi-family residential project competitions, held in Paris in 2011. Since 30 buildings in the survey will be constructed in Paris in a couple of years, current trends of the elevations of the multi-family residential buildings can be extracted. Historically and also currently, in France, the multi-family housing has been studied to solve the various social problems; especially in Paris where the historical buildings and the modern and the contemporary buildings stand together in perfect harmony. The uniform elevations of the multi-family residential buildings in Korea, have been consist problems in the country. By studying the building elevations in Paris, the solutions to solve the current problems and to improve the situation, can be found. The study will be discussed in three different categories. First of all, the volume and the mass of building in the survey buildings, will be analyzed. Secondly, the openings in the facade, such as the windows and the balconies of the survey projects, will be analyzed. Finally, the materials and the colors of the facade will be discussed. By analyzing the elevations of the multi-family residential building projects, which had won the competitions, and are soon to be built in Paris, the various experiments and the attempts in building elevations, currently happening in Paris which is mostly known as a Haussmann style city, can be presumed, as well as the willingness of the city to reserve the historic buildings in the city.

  • In this study, the colors and characteristics of Gwangbok-ro of Busan were analyzed in the standpoint of local images based on the examination of the facade designs of stores along the road of Gwangbok-ro, Busan a main street with massive population flow. To that end, the facades of stores, correlation with the city, color and locality were examined, and after the status of facade designs in Gwangbok-ro were identified through case survey by it, color images were analyzed. For color analysis, Munsell color system was used as basic tool. As a result of examining the colors in Gwangbok-ro area, the following status could be analyzed on 3 attributes of hue, brightness and chroma: First, analysis results of hue indicated that dominant color that covers 70% or more of the area represented mid brightness and low chroma in GY(36.1%) series, subsidiary color which covers 25% or more of the area mid brightness and low chroma in YR(26.5%) series, and accent color that covers less than 5% of the area high brightness and low chroma of GY(40%) series. Second, in brightness analysis, dominant color mostly represented mid brightness, subsidiary color mid brightness and accent color high brightness respectively. In particular accent color showed more intensive crowding phenomenon in high brightness. Third, as for chroma, dominant color, subsidiary color and accent color all are gathered in low chroma, however in small number of accent colors, peculiar high chroma appeared notable. In conclusion, the colors of Gwangbok-ro area analyzed based on the facade design of the stores along the road in this study were superficial colors that reflect the life of people in the area, artificial colors by improvement of the local environment. This study is meaningful in that the image of Gwangbok-ro was found through building colors in one part of the city Busan. It is judged that the study results would become useful as reference document in planning out environment colors later on.

  • Façade design makes the customer to select and remember of commercial space. Therefore, if it can be identified characteristics of perception in image evaluation, it will be possible to easy visiting space and re-selection with motivation through identity and differentiation of commercial space. For this study, cafes among commercial facilities were selected for the appreciation of the differentiated design features attracting customer's eyes through space image evaluation by gender. The followings are the conclusions drawn from the study. First, when the features of mean and deviation of [Factor 1] were employed for the appreciation of the perceptual characteristics of both men and women, it was clearly found that customers regards the facade design as a coarse one even though they are confused about whether the facade design is the straightened-up one. Second, customers perceive facade design as the one which is bright but not unique through [Factor 2] while in the process of selecting adjectives to describe it men's perception as to "being vivid but interesting" was dispersed and women's as to "Being bright" was also dispersed, too but the women perceived it as "being opaque". Third, it was revealed that the perceptual characteristics of [Factor 3] were perceived as "warm but boorish" and "warm but crude" by men and women respectively. Fourth, most (80%) of the adjectives employed for vivid description of their perception by both genders were found to be consistent.
