지구온난화로 인한 온실가스 배출 감소에 대한 관심도가 증가하고 있으며, 이 중 온실가스 감축 계획으로 에너지 소비 감소 계획이 제안되고 충족을 위한 건축물이 열관류율 기준이 강화되었다. 한국에서는 소비되는 전체 에너지 중 약 25%는 건축부문에 사용되고 있으며 건물 에너지 소비량 감소를 위한 열전도율이 낮은 건축자재 또는 단열재 개발이 요구되고 있으며, 열전도율이 낮은 목재의 활용 사례도 증가하고 있다. 또한 내부 마감재로 사용될 경우 건물 에너지 소비가 최대 7%까지 감소된다는 선행연구 결과를 바탕으로 본 연구에서는 일반적으로 실내마감재로 사용되는 3가지 유형의 마감재(시멘트, 오동나무, MDF)에 따라 열전달특성 및 열용량을 비교하였다. 본 연구를 통하여 열 이동은 복사열의 형태로 전달되며 오동나무 마감재 사용시 에너지량과 열전달량이 가장 많은 결과로 실내 마감재로 목재 사용 시 건물 내부의 에너지 효율을 향상시킬 것으로 판단된다.

With the development of cities, the density of the population is continuously increasing as buildings become larger and more high-rise, but since the Haeundae residential complex fire in Busan in 2010, there has been a growing need to meet the fire protection performance of buildings as large-scale fires continue to occur every year. On the other hand, fire doors, which are one of the fire protection performance of buildings, have been judged unqualified in 82% of cases when fire doors constructed on the actual site were inspected after completion. The reason for this is that paper honeycomb and glasswool, which are used as core materials for fire doors, absorb moisture, reducing thermal insulation performance, and sagging due to increased weight, leading to performance degradation due to warping in empty spaces. To overcome these problems, research is underway to apply lightweight aerated concrete, an inorganic material, as a core material. Therefore, in order to select a blowing agent that produces stable bubbles prior to the production of lightweight bubble concrete for application as a fire door inner core, this study examined the physical performance according to the type of blowing agent and dilution concentration, and the following conclusions were drawn. Compared to vegetable bubbles and independent bubbles, synthetic bubbles have 3~8% higher thermal conductivity than independent bubbles, but 3~6% lower slurry density than vegetable bubbles, and 2~13% higher compressive strength, which is thought to be an improvement of synthetic bubbles.

최근 친환경건축물인증제도, 주택성능등급표시제도를 비롯하여 실내공기환경에 대한 기준, 친환경상품인증기준 등 환경관련 제도 및 규정이 마련되면서 공동주택의 신축 및 리모델링 공사에 이에 대한 고려가 필요한 상황이다. 특히 공동주택 리모델링 공사는 거주자가 사전에 정해진 상태에서 공사를 진행하므로 이들에 대한 의견수렴과 사용되는 소재에 대한 요구분석이 신축에 비해 중요하다는 특성이 있다. 하지만 현재 국내에서 시행 중에 있거나 최근 완료된 리모델링 공사의 시공자는 친환경 소재 적용에 대한 거주자의 적극적인 의견수렴 과정이 미비하였고, 친환경상품인증원의 최우수 등급을 받은 친환경 제품을 거주자의 요구에 의해 적용한다기 보다는 공동주택의 홍보의 일환으로 사용하고 있는 실정이었다. 또한 공동주택 리모델링 거주자는 친환경 제품의 인증기준에 대한 이해가 부족하여 친환경 제품의 등급을 맹목적으로 신뢰하는 경우가 있었고 적용되는 친환경 소재에 대한 요구가 매우 정성적인 특징이 있다. 따라서 공동주택 리모델링 거주자의 친환경 소재에 대한 요구사항을 조사하고 이를 정량적으로 분석하여 만족도를 극대화 할 수 있는 친환경 소재를 리모델링 공사에 적용하여야 한다.

If you compare recent works in small commercial places along with the terms such as Post-Modernism, Late-Modernism, and Dismantling, to those of 60's and 70's, you will discover for sure that recent works try to model individually with 'surface'. Expressing the responses to the multilateral cultural desires is available through the organization of surface, so are the re-presentationsof classic notions by adding decorations to the vertical walls, which are different from modern constructions that have persisted on only space itself as a main point. These trends are various organizing techniques with forms, decorations, materials, color etc. and made the surface modeling develop. What a 'surface element' means as a concrete notion in a design process in a commercial place is enormous. So, it implies lots of notions and logic, and can be a strong message-conveying means as well as an expressional language. At this point of view, the research was limited to Facade, which is treated as a creational object to a designer all the time in order to study what kind of system the surface organization has in a small commercial place. This is to find out what kind of system the designer uses to make the spatial images, orders and forms through surface, but ultimately it is to discover the designer's basic tecniques that he or she uses when planning. To sum up, we have studied the meanings of the composition and the changes of the organization of Facade to analyze the organizing techniques in Pasad in a small commercial construction which designers planned as material. We have also investigated the organizing techniques of surface by examining and analyzing the elements of Facade organizing techniques, i.e. its form, decoration, material, pattern and color.

본 연구에서는 공사현장에서 사용하고 있는 칼라 부직포의 화재위험성을 평가하기 위하여 콘칼로미터와 수직화염전파성 실험을 실시하였다. 그 결과 칼라 부직포는 표변에 화염이 착화가 되는 것이 아니라 용융이 된 상태에서 가연성가스가 발생되어 착화되는 연소형태를 보였다. 수직화염전파성 실험의 경우 가열강도에 의해 칼라 부직포가 수축 및 파단되어 화염이 전파되지 않을 정도로 열에 매우 취약하였다. 총방출열량은 2.66 MJ/$m^2$로, 건축물 실내마감재료 난연성능평가의 준불연재료(10분), 난연재료(5분) 8 MJ/$m^2$ 이하 기준에 규합되지만 이것은 내장재의 기준으로 칼라 부직포가 난연성능을 가지고 판단할 수 없으며 외장재에 대한 난연성능과 실험방법에 대한 기준이 마련되어야 한다고 판단된다.

Cityschumers experience the urban with the visual perception while walking an average speed of 4km per hour. At this time, recognition of the color field accounts for more than 70%. Therefore, in this paper the environmental color of urban street is examined by dividing the pedestrian visual field area. In the urban street, the area of the visual field area of the pedestrian is divided into Ground Plane, Roadside, Canopy and Building Wall. In addition, we observe and color survey the environmental color of Exhibition Road, which is the northern side space of South Kensington in London, which adopted the world's first shared space. The color of the visual filed area was dominated as YR, GY, Y, PB. The Ground Pland was dominated by the YR. The reason for this is that the color of the floor has changed due to the shadows of surrounding architecture and facilities. Roadside was dominated in various ways such as GY, BG, PB, B and P. Canopy was mainly composed of PB, GY, etc. It was found that the material color of the lower part of the architecture was reflected. The architecture wall was affected by the reflectance and absorption rate of the transparent material. The first image that comes to mind when thinking about the urban is the street where pedestrians walk, feel and enjoy themselves. Therefore, it is suggested that various policy frameworks for managing and managing urban planning professionals may be different from the perceptions of pedestrians active in mega cities.

20% of total energy use to sustain temperature of building inside. In this reasons, researchers effort to improve the thermal insulation capacity with new wall system. Using appropriate materials and consisting new wall system should considered in energy saving design. OSB(Oriented strand board), Larch lining board used to consist wall system. $2{\sim}6$ Larch lining board has tongue & groove shape for preventing moisture. Comparing with gypsum board and green timber lining board as interior sheathing material, temperature difference of Green timber wall system was bigger than temperature difference of gypsum board wall system. This aspects indicate that Green timber wall system was revealed higher thermal insulation property than gypsum board wall system. Gypsum board portion transfer heat easily because temperature difference gradient of gypsum board wall system was smaller than OSB wall system. Total temperature variation shape of G-4-S and G-6-S show similar model but, temperature variation shape in green timber wall portion assume a new aspect. The purpose of this study was that possibility of thermal insulation variation and new composition of wall system identify to improve thermal insulation performance. In the temperature case, this study shows possibility of improving thermal insulation performance. Humidity, sunshine and wind etc. should considered to determine building adiabatic properties.

Diagrid structures have been introduced as a fairly modern lateral load-resisting system in the design of high-rise buildings. In this paper, a novel diagrid system called tube-in-tube diagrid building is introduced and assessed through pushover and incremental dynamic analyses. The main objectives of this paper are to find the optimum angle of interior and exterior diagrid tube and evaluate the efficiency of diagrid core on the probability of collapse comparing to the conventional diagrid system. Finally, the seismic performance factors of the proposed system are validated according to the FEMA P695 methodology. To achieve these, 36-story diagrid buildings with various external and internal diagonal angles are designed and then 3-D nonlinear models of these structures developed in PERFORM-3D. The results show that weight of steel material highly depends on diagonal angle of exterior tube. Adding diagrid core generally increases the over-strength factor and collapse margin ratio of tall diagrid buildings confirming high seismic safety margin for tube-in-tube diagrid buildings under severe excitations. Collapse probabilities of both structural systems under MCE records are less than 10%. Finally, response modification factor of 3.0 and over-strength factor of 2.0 and 2.5 are proposed for design of typical diagrid and tube-in-tube diagrid buildings, respectively.

As the air pollution progresses, the pollution degree of the indoor air quality is increased, and when the pollution degree of the indoor air quality is increased, it causes respiratory diseases and skin diseases. In addition, volatile organic compounds are released from the materials used for architectural interior decoration, and volatile organic compounds are the main cause of polluting indoor air quality. In order to improve indoor air quality, we tried to secure indoor air quality pollution by using photocatalyst which has the function of decomposing harmful substances. photocatalyst is a material that promotes chemical reaction by absorbing light. The photocatalyst used in the experiment was TiO₂, In this study, an adsorption type hardener for reducing volatile organic compounds was prepared by photocatalytic reaction. the formaldehyde and CO₂ concentrations of the cured products were analyzed according to the TiO₂ content.

본 연구는 장애인의 이용도가 높은 환경을 개선하고자 하는 궁극목표를 위한 단계적 연구 중 '국외법규 고찰 및 사례분석'에 관한 것이다. 이를 위해 장애인 복지에 관한 규범과 기술적인 기초를 북구에서 가장 먼저 미련하였던 스웨덴을 연구대상으로 하여 건축법규와 장애인 관련 지침을 고찰하고 스톡홀름과 오슬로의 교통시설의 환경디자인 요소를 분석하였다. 그 결과, 스웨덴의 건축법규(BBR 94)는 그 기본 개념이 접근성 안정성 효율성에 있으나, 의무사항으로 규정된 항목이 매우 적고 구체적인 세부지침도 미흡하였으며, 국립 스웨덴 장애인 연구소에서 더욱 상세한 세부지침을 제공하고 있었다. 사례분석 결과,4개의 대상시설이 정도와 방법의 차이는 있으나 건축법규에서 의무화하거나 권장하고 있는 사항보다 실내 환경에서의 접근성 적용성 안정성 이동성 지원성에서 치수 색채 재료 조명 등의 세부요소를 이용하여 다양하게 해결안을 모색하고 있는 것으로 평가되었다.
