The Contemporary consumer society demands companies to emphasize more on the brand marketing that can deliver the brand identities distinguished from those of competing companies. In today's environment, the meaning of consumption is not only a simple purchase of a product, but also assimilation into images, experience and emotional aspects of the brand. The flagship stores of brands take the advantage of the tendency seriously and utilize the envelopes of the building as marketing catalysts to establish their brand identities. This paper aims to investigate the possibility of the architectural envelope as a marketing element to establish the brand identities, by analyzing the design techniques that enhance the visual effects utilizing innovative application of material, pattern and connection details. it is studied that the function of architectural envelope's change from past to recent date and role of architectural envelope as means of marketing for expression brand image in contemporary commerce space and elements that can be applied on architectural envelope with theoretical consideration about marketing and brand identity. Also this paper will research about experience elements because the process for consumers to recognize brand image with architecture is the process of visual experience. And through example research, this paper will study interrelationship between visual system of cognition to be expressed on architectural envelope.

본 연구는 WUFI Pro 5.3을 이용하여 한국농어촌공사에서 제시하고 있는 농어촌 표준 목조주택 설계를 기준으로 목조 벽체의 hygrothermal 거동에 대한 평가를 실시하였다. 그 결과, 2010년도에 제시된 벽체보다 2014년도에 개선된 벽체의 Total Water Contents (TWC)가 더 낮게 나타난 것을 확인하였고, 3년간의 평가에서 TWC가 일정하게 유지되는 동적 안정 상태에 도달하였음을 보아 hygrothermal 환경을 적절히 고려하는 개선임을 확인하였다. 또한 농촌지역과 어촌지역을 구분지어 hygrothermal 거동을 평가한 결과, 벽체가 해당지역의 온도보다 상대습도에 큰 영향을 미치는 것을 확인하였다. 또한, 목재 기반 재료의 과도한 수분 함량 문제는 실외마감의 재료를 바꾸는 것으로 어촌지역에도 적용이 가능한 벽체로 개선할 수 있었다. 곰팡이 성장 위험의 경우, 초기 실내 설정온도에서 여름철에 곰팡이가 성장할 가능성이 높은 것으로 나타났으며, 이를 고려하여 여름철 실내 설정온도를 변화시키는 것으로 개선되었다. 이러한 결과를 통해, 건축설계 단계에서 WUFI 프로그램과 같은 hygrothermal 거동 분석 프로그램을 이용하여 건축물의 수분에 대한 문제를 미리 분석하고 이에 맞는 벽체의 개선이 필요하다고 판단된다.

In 1999 Marmara and 2011 Van earthquakes in Turkey, majority of the existing buildings either sustained severe damage or collapsed. These buildings include masonry infill walls in both the interior and exterior R/C frames. The material of the masonry infill is the main variant, ranging from natural stones to bricks and blocks. It is demanding to design these buildings for satisfactory structural behavior. In general, masonry infill walls are considered by its weights not by interaction between walls and frames. In this study, R/C buildings with infill walls are considered in terms of structural behavior. Therefore, 5 and 8-story R/C buildings are regarded as the representative models in the analyses. The R/C representative buildings, both with and without infill walls were analyzed to determine the effects of structural behavior change. The differences in earthquake behavior of these representative buildings were investigated to determine the effects of infill walls leading structural capacity. First, pushover curves of the representative buildings were sketched. Aftermath, time history analyses were carried out to define the displacement demands. Finally, fragility analyses were performed. Throughout the fragility analyses, probabilistic seismic assessment for R/C building structures both with and without infill walls were provided. In this study, besides the deterministic assessment methodology, a probabilistic approach was followed to define structural effect of infill walls under seismic loads.

This project addresses the product identification and design application of corrugated products for kinetic architectural applications. Initially, an architectural approach to product identification was carried out with the end goal of demonstrating application design principles of numerous novel architectural examples from the forest products industry. A design and prototyping stage followed demonstrating such application design principles and functional analysis on various novel architectural examples. The results of coupling product identification with proven application advantages will be of potential value not only to architecture but also to other designers in the arts and sciences. The general motivation for the research arises out of a growing interest corrugated and paper products to be ideally suited for various architectural applications for their unparallel environmental benefits. Applications in architecture that use fewer resources and that adapt efficiently to complex and changing conditions are particularly relevant for an industry (architecture) that is increasingly aware of its environmental responsibilities. Corrugated and paper products are highly under-utilized by the building industry as design choice material for both interior and exterior applications. An increased awareness of the benefits of corrugated and paper products coupled with a process of designing for the total use and reuse will prove to be a valuable means by which issues of energy efficiency and environmental quality of buildings could be enhanced to be more efficient, affordable, and therefore reach a broader audience of users.

The purpose of this study is to reevaluate the performance of Hanji as a architectural material. Recent studies report that one of the causes of the Sick-HouseㆍSick-Building Syndrome is due to the contaminants from interior materials and the lack of ventilation. In this study, the properties of Hanji are investigated. The major focuses of this research are (1) how efficient the Hanji is for ventilation of the house and (2) whether the usage of Hanji brings required ventilation volume to the house. According to the test results, differential pressure in the air and the amount of ventilation showed linear relationship. Test results differ from various kinds of Hanji. Since houses usually have double window system, Hanji can be used to the windows system, especially for inner part of double window system. It is suggested that the combination of Hanji windows for the inner part and glass windows for outer part is very effective, and offers a solution to improvement of indoor air quality and the lack of ventilation with passive ventilation that has less energy consumption.

Wood plastic composite (WPC) is a green composite made of wood flour and thermoplastics to provide better performance by removing the defects of both wood and plastics. However, relatively low thermal stability and poor fire resistance of wood and plastics included in WPC have been still issues in using WPC as a building material for interior applications. This study investigated the effect of environmentally-friendly flame retardants (EFFRs) on the mechanical, thermal, morphological, and water absorption properties of wood flour (WF)/talc/polypropylene (PP) composites in comparison with neat PP. The whole EFFRs-filled WF/talc/PP composites showed higher values in flexural strength, flexural modulus, and impact strength compared to neat PP. In thermal properties, aluminum hydroxide (AH)-filled composite showed a $36^{\circ}C$ reduction in maximum thermal decomposition temperature ($T_{max}$) compared to neat PP, but magnesium hydroxide (MH) played an important role in improving thermal stability of filled composite by showing the highest $T_{max}$. From this research, it can be said that MH has potentials in reinforcing PP-based WPCs with improvement of thermal stability.

Korean traditional houses have been developed in harmony with natural environment and comfortable indoor condition by using the natural resources including building layout, space composition and materials. Originally Korea traditional architectures have used wood lintel constructions and loess walls through the many years. Theses loess have many strength such as highly heat capacity, controling of humidity, a deodorant than any other materials. Nowaday it is recommended to use exterior and interior walls in loess wall to meet the eco-friendly materials to improve our residental environmental. Thus this study aims to research the sound insulation performance of traditional loess brick wall varied with thickness, thermal insulation materials and cavity wall. The sound insulation performance of these loess walls are compared with other masonry wall's and sound insulation performance of th walls were tested in anechoic laboratory to measure the sound transmission loss of these walls.

This study was carried out to explore a new application of traditional Hanji and obtain fundamental properties for producing Hanji wallpaper by incorporating ceramics from wood and rice-husk as an interior building material. The results of properties determined were summarized as follows: The addition of ceramics in Hanji paper reduced its apparent density, but increased bulk density due to the ceramic particles distributed on the surface and inside the fiber of Hanji wallpapers. In particular, woodceramic particles were specifically distributed on the fiber surface, while particles of rice-husk ceramics were permeated into the inside surface of fibers. The density of rice-husk ceramics were greater than that of woodceramics. The physical properties of Hanji wallpapers, such as breaking strength, wet breaking strength, burst strength, tear index and folding endurance were deteriorated with the addition of ceramics. However, the addition of woodceramics in the Hanji wallpaper resulted in better strength in most cases than that of rice-husk ceramics, except tear strength. Therefore, an optimum addition level of woodceramics into the wallpaper was found to be 5% on the basis of intensity. The addition of ceramics also prolonged the combustion time because it lowered air permeability and brightness of the wallpaper.
