Government efforts for green growth policy initiatives demand low-carbon technologies in the road construction industry. The purpose of this paper is to develop an algorithm of a road alignment design solution for establishing the multi-dimensional information, and to calculate carbon emission quantity due to the geometric design elements in the planning phase of road alignment. The paper developed a calculation method for carbon emission quantity by drawing a speed profile reflected in the operating speed, acceleration and deceleration, which are majors factor of carbon emissions while driving and by applying a carbon emission factor. From this effort, it enabled alignment planning to reduce carbon emission. Object-based parametric design methods of the cross-sections were proposed for alignment planning, and the paper demonstrated a BIM-based road alignment planning solution. The proposed solutions can provide multi-dimensional information on carbon emission quantity and cross section elements through driving simulation. It is expected to allow construction of eco-friendly roads by deriving optimal road alignment to minimize environmental costs.

Recently, R&D demand for environmental friendly vehicle has rapidly increased due to its global environmental issues such as global warming, energy and economic crisis. Under this situation, the most realistic alternative way for environmental friendly vehicle is a clean diesel vehicle. The common-rail fuel injection system, as key technology of clean diesel vehicle, consists of a high pressure pump, common-rail, high pressure fuel line and electronic control injector. In common-rail high-pressure fuel injection system, high pressure wave of injection system and geometry of injector elements have a major effects on high-pressure fuel spray. Therefore, in this study, the numerical model was developed for analysis about the common-rail fuel pressure pulsation by using AMESim code. We could secure stability of common-rail high-pressure fuel injection system through optimal design of fuel line.

In order to make an effective use of spatial resources in the city, detailed environmental plan strategies based on 'culture' are needed. An integral part of city spaces-'underground space' serves as one of the spatial resources with much effective usage potentials. Hence, 'underground space' needs cultural vitality. The purpose of this study is to propose an thorough indoor environmental plan guideline for the cultural vitality of 'underground space'. The methods used to conduct research include precedent study reviews and survey. Through this research, following conclusions are drawn. First, to promote cultural vitality at the 'underground space', it must be transformed into the cultural public place to be utilized for cultural activities by residents. Second, the 'underground space' requires 'concept of eco-friendly space for clean environment'. Third, 'safe environment' concept must be installed in the 'underground space' to promote the cultural vitality. Fourth, the 'underground space' requires 'complex/block level network plans between cultural spaces in addition to horizontal/vertical walking network between cultural environments in ground level and underground spaces. Fifth, the 'underground space' requires underground public cultural space plan through 'reasonable underground development with considerations of the facilities related to education, culture and history'. Sixth, 'public cultural space plan for various cultural spaces' and 'supply of space for cultural activities for residents and design plan for mutual culture exchange' are necessary.

입체녹화가 도시환경을 향상시키는 효과가 있는 것으로 알려지면서 친환경 건축물의 새로운 대안으로 부각되고 국내적용에 대한 다양한 연구가 필요해지고 있다. 본 연구의 목적은 국내외 건축물 준공사례를 대상으로 건축물 내 외부에 반영되고 있는 입체녹화의 공간특성을 조사하고 구성체계 및 디자인요소를 분석하여 친환경구성을 위한 부문별 디자인 적용요소의 발전방향을 제시하는 데 있다. 분석결과, 입체녹화는 건축물 내 다양한 외부공간을 증가시키기 위하여 대형화하는 고밀도 개발형태를 보이며 초기에는 전시, 교육 등 공공시설이 많았으나 최근에는 공동주택 사례가 증가하고 있다. 공동주거 Unit에 다양한 근접공간을 도입하고 사적 공간에서 독립적인 녹화공간을 제시하는 등 거주자의 선호조건에 따라 선택적으로 근접공간을 이용하도록 계획하는 방법은 일률적인 국내 공동주거의 디자인을 지양하고 거주자의 다양한 행위를 유도할 수 있다. 새로운 공간분위기와 다양한 옥외공간으로 인한 커뮤니티 장소들은 사회적 상호 작용을 통해 공동주거의 생활패턴을 변화시키고 새로운 마을공동체를 조성하는 방법이 될 것으로 판단된다. 또한 대지의 환경특성을 적극적으로 반영하고 건축물 형태에 자연지형과 경사로를 이용하는 경향을 뚜렷이 보이고 있어 외부공간 환경조성 디자인요소에 대한 후속 연구도 필요하다.

Bird collisions with glass are a substantial source of human-caused avian mortality. It has been estimated that between 100 million and 1 billion birds die in collisions with windows every year, and bird-window collisions can have a particularly serious impact on populations because glass is dangerous for strong, healthy, breeding adults. The purpose of this study are to address the bird-window collision issue and to provide suggestions for bird-safe development by reviewing precedent studies on bird collision and analyzing bird-friendly design guidelines. Typically reflections of the sky, clouds or trees on glass, green plants in lobbies, and lights attract and confuse both migrating and resident birds. Therefore birds fatally fly into the glass because they do not recognize that reflections are false and that glass is a barrier. Many cities such as Toronto, Chicago and New York have made efforts on reducing the bird collision by encouraging the creation of environmentally conscious and bird-safe buildings. The USGBC also introduced a bird-safety credit as part of its environmental certification process, called LEED. The results of the study presented that architects and builders can help reduce or prevent bird from collisions in both new construction and existing structures with creative use of design elements. The measures to reduce bird collisions include using glass with an embedded pattern, opaque or translucent films, decals, dot patterns, awnings, louvers, and grilles. Turning off lights after midnight during the spring and fall migrations can be part of the solution as well. In order to reduce bird mortality, the most important thing is to generate awareness of the issue among designers, builders, as well as the public. Also local governments need to develop bird-friendly design guidelines and planning mechanisms to encourage bird-safe development and building operation.

Purpose: Korean society has already entered an aged society but there aren't many evidence-based studies on the elderly-friendly design elements in the apartment environment, which is the main residential type in Korea. The main purpose of this study is to verify the necessity and expandability of the outdoor environment design in the public rental apartment complex through the evaluation of the effectiveness and satisfaction of SMG(Seoul Metropolitan Government) Cognitive Health Design Project in GR 1 apartment complex. Methods: The research subjects were GR 1-complex as experimental group and the nearby Wolgye Deer 1-complex as control group, both public rental apartment and located in Seoul. As a research method, the survey was conducted before and after the implementation of SMG project for residents of the apartment. A total of 200 preliminary surveys and 203 post surveys were conducted. Results: As a result of this study, residents' accidents related safety have decreased, and both the frequency of use and satisfaction of most facilities have increased. It is noteworthy that the increase in cognitive items in the post-survey. Also, 74.5% of the residents evaluated that the complex was better to live after the project was implement. Implications: The fact that the preliminary surveys were not conducted for the same person is considered as the limitation of the study, but it is meaningful in that it systematically assesses the effectiveness of the project on the cognitive health of the outdoor residential environment towards age-friendly city.

기후변화에 관한 파리협정(Paris Agreement)은 우리나라의 친환경정책에 많은 영향을 미칠 것으로 보인다. 그동안 건설공사의 설계단계에서 탄소발생량을 줄이기 위한 친환경설계가 적용되어 왔다. 그러나 친환경건축물 인증에 해당하는 프로젝트 외에는 소극적 적용에 그치고 있다. 설계에 친환경요소를 반영하기 위해서는 현재 100억 이상 모든 건설공사의 기본설계 및 실시설계단계에 적용되고 있는 설계VE(Value Engineering) 제도를 활용할 필요가 있다. 하지만 현재 적용되고 있는 VE Job Plan은 친환경 요소를 일부 반영하는데 그치고 있으므로 그 효과는 미미할 수 밖에 없다. 따라서 기존 VE 기법에 친환경요소를 반영한 새로운 형태의 친환경VE 기법의 개발이 필요하다. 연구의 결과 환경비용의 개념은 회계학적으로 정의되고 그 비용의 산정은 이산화탄소 배출량을 기반으로 하는 탄소세, $CO_2$배출권 거래가격, 지불의사금액, 탄소생산성 개념을 이용하는 방법이 많이 사용되고 있었다. 그러나 설계단계에서 친환경VE에 활용하기 위해서는 탄소생산성 개념을 포함한 새로운 개념의 모델이 필요하다. 새로운 개념의 친환경VE모델은 $CO_2$배출량과 잠재적환경오염지수를 사용하는 모델이다. 본 연구에서는 친환경VE의 한 축을 담당할 환경비용에 대한 개념과 친환경가치모델을 정립하고자 하였다.
