  • IT기술의 발달과 더불어 국내산업계는 저탄소 녹색성장에 대한 관심이 증대하고 있다. 기존 건축물들의 막대한 에너지 소비량을 보았을 때 건설산업은 이러한 동향의 중심에 서있다고 해도 과언이 아니다. 따라서 보다 효과적이고 정량화된 방법에 따라 건축물의 친환경 성능을 분석하고 관리하는 친환건설경영이 요구되어지고 있다. BIM이 가지고 있는 객체기반의 파라메트릭 모델링 기술과 생애주기관리의 개념은 친환경 건축물의 성능을 분석하고 관리하는데 유용한 도구가 될 것으로 여겨지며, 따라서 본 연구에서는 친환경건설의 필수 관문이라고 할 수 있는 친환경 인증의 평가항목에 있어서 BIM기반의 시뮬레이션 시스템을 제안하였다. BIM 기반의 친환경건축물 시뮬레이션은 친환경인증의 준비 과정 및 시공과정에서 보다 합리적인 의사결정을 지원할 수 있을 것으로 기대된다.

  • The effectiveness of Building Information Modeling (BIM) tools and processes has been recognized by the industry and owners are beginning to adopt Triple Bottom Line accounting practices, to enhance economic performance and environmental and social performance. However, the widespread and practical application of Green BIM remains largely unrealized. The authors identify that lack of understanding of the applicability of sustainability metrics to BIM design process is a significant barrier to this adoption. Through literature review this paper outlines the various sustainability metrics available to construction and elaborates on the potential of BIM for sustainable design. The paper maps and correlates applicable concepts of sustainability evaluation systems to BIM and describes the constraints in current BIM tools.

  • 최근 전 세계적으로 환경문제에 대한 관심이 증가하면서 건축분야에서도 친환경을 위한 노력이 증가하고 있다. 본 논문은 BIM 모델에 근거하여 친환경 현장시공의 위험도 관리에 관한 연구를 하였다. 친환경건축은 지속가능한 발전을 위한 건축으로 3R(Reducing environment pollution, Reducing resource use and Reducing energy source use)표준에 도달해야 한다. BIM은 3D설계, 시공, 유지관리의 효율성 극대화를 위해 건축설계를 2D에서 3D로 전환하고 수량, 공정 및 각종 분석 등의 정보를 통합적으로 활용하는 기술이다. 그리고 4D는 3D기술에 시간을 추가한 것으로써, 3D 모델이나 4D모델에 기반을 두고 있으며, 원가관리, 계획관리, 설계 및 재료관리 등이 BIM 때문에 변화하고 확대하고 있다. 이를 통해 위험관리도를 분석할 수 있다. 본 논문은 먼저 세 분야(환경요소, 자원요소, 에너지요소)에서 친환경 시공의 위험요소를 분석하고 판별하는 방법을 소개한다. 현장에서 일어날 수 있는 위험 확인은 이 공사를 통해서 위험을 판별하고 위험특성도를 찾을 수 있다. 다음으로 친환경위험과 BIM의 관계를 분석한다. 요즘은 BIM이 많이 활용되어서 쉽게 BIM 모델의 데이터베이스를 이끌어 낼 수 있고, 위험을 미리 예방할 수 있으며 옮길 수도 있다. 친환경위험의 세 분야는 분석을 통해서 개별적으로 위험관리를 할 수 있다. 친환경건물은 에너지분야 비율이 비교적 많은데 현장시공의 친환경도 비슷하다. 따라서 위험을 미리 예방하여 에너지를 절약할 수 있다. 소프트웨어를 통해 공간과 에너지성능을 잘 알 수 있고, 사용될 에너지의 전체를 계산할 수 있고, 라이프 사이클 등을 미리 알 수 있다. 그래서 4D모델이나 5D모델을 이용하면서 시공인원이 잘 판별하면 위험을 예방하거나 옮길 수 있다. 특히 시공환경 분야, 시공소음, 수질 오염 등의 문제점을 분석할 수 있다. 친환경공사는 복잡하고, 시간주기도 길어서 자원과 에너지를 많이 소모하기 때문에 친환경위험관리에 적합한 판별이 필요하며, 이를 통해 지속 가능한 발전을 할 수 있다.

  • Given the barriers to implement green building rating systems, Building Information Modeling (BIM) was suggested as an effective solution integrating information into one model and saving substantial time to facilitate certification process. Synergies between BIM and Leadership in Energy and Environment Design (LEED), the most widely used rating system, have been researched for a few decades. This paper demonstrates literature review about the development of integration between BIM and LEED. The research focuses on synergies between BIM and Green Standard for Energy & Environmental Design (G-SEED) in Korea, as one of important strategies to mitigate greenhouse gas emission. The research compares LEED and G-SEED related items based on evaluation contents. The result manifests G-SEED and LEED share many common items in different degrees. Therefore, it is entirely possible for G-SEED and BIM to adapt same developing mode of LEED and BIM. Moreover, the study measures the potential of BIM in application process of G-SEED certification by investigation of credits in LEED and G-SEED can be earned by BIM. The results of paper indicate the documentation support LEED and G-SEED may be prepared directly, semi-directly and indirectly via sustainability analyses software in BIM.

  • Today, there is a growing need of environment-friendly buildings, so-called 'green', facilities, and energy saving buildings to decrease environmental pollutants released into cities by construction activities. Green-Building Information Modeling (Green-BIM) is a purpose-built solution which supports to forecast energy consumption of 3-D model of a building by augmenting its primary 3-D measurements (width, height and depth) with many more dimensions (e.g. time, costs, social impacts and environmental consequences) throughout a series of sequential phases in the lifecycle of a building. The current study was carried out in order to integrate vegetation systems (particularly green roof and green wall systems) and investigate thermal performance of the new Sainsbury's building which will be built on Melton road, Leicester, United Kingdom. Within this scope, a 3-D building model of the news Sainsbury's building was first developed in $Autodesk^{(R)}$ $Revit^{(R)}$ and this model was then simulated in $Autodesk^{(R)}$ $Ecotect^{(R)}$once weather data of the construction site was obtained from $Autodesk^{(R)}$ Green Building $Studio^{(R)}$. This study primarily analyzed data from (1) solar radiation, (2) heat gains and losses, and (3) heating and cooling loads simulation to evaluate thermal performance of the building integrated with vegetation system or conventionally available envelops. The results showed that building integrated vegetation system can potentially reduce internal solar gains on the building rooftops by creating a 'bioshade'. Heat gains and losses through roofs and walls were markedly diminished by offering greater insulation on the building. Annual energy loads for heating and cooling were significantly reduced by vegetation more significantly through the green roof system in comparison to green wall system.

  • Recently, sustainable building design, a growing field within architectural design, has been emerged in the construction industry as the practice of designing, constructing, and operating facilities in such a manner that their environmental impact, which has become a great concern of construction professionals, can be minimized. A number of different green rating systems have been developed to help assess that a building project is designed and built using strategies intended to minimize or eliminate its impact on the environment. In the United States, the widely accepted national standards for sustainable building design are known as the LEED (Leadership in Energy and Environmental Design) Green Building Rating System. The assessment of sustainability using the LEED green rating system is a challenging and time-consuming work due to its complicated process. In effect, the LEED green rating system awards points for satisfying specified green building criteria into five major categories: sustainable sites, water efficiency, energy and atmosphere, materials and resources, and indoor environmental quality; and sustainability of a project is rated by accumulating scores (100 points maximum) from these five major categories. The sustainability rating process could be accelerated and facilitated by using computer technology such as BIM (Building Information Modeling), an innovative new approach to building design, engineering, and construction management that has been widely used in the construction industry. BIM is defined as a model-based technology linked with a database of project information, which can be accessed, manipulated, and retrieved for construction estimating, scheduling, project management, as well as sustainability rating. This paper will present a framework representing the building knowledge contained in the LEED green building criteria. The proposed building knowledge framework will be implemented into a BIM platform (e.g. Autodesk Revit Architecture) in which sustainability rating of a building design can be automatically performed. The development of the automated sustainability rating system and the results of its implementation will be discussed.

  • Since the importance of eco-friendly architecture is rapidly increasing, BIM receives significant attention as an alternative that would derive the practical results and apply the design values of eco-friendly design elements to the architectural design process. Therefore, this study establishes an Integrated Design System based on Green BIM by applying the eco-friendly design values logically and systemically. The study also proposes practical case studies to examine the possibility of application. As a result, the framework of Green based Integrated Design System(gbIDS) and a prototype of Web-based gbIDS were developed to improve the working environment of small architectural firms.

  • Green Infrastructure has been considered as one of strategies for flood mitigation in cities. Although, the diverse benefits of green infrastructure implementation are studies, there is a lack of research on the relationship between spatial composition and configuration of green infrastructure and urban flood mitigation. To address this gap, this study 1) utilized high-resolution satellite imagery to analyze spatial composition and configuration of green infrastructure in highly developed seven cities in South Korea, and 2) conducted an empirical analysis to find the relationship between economic losses from flooding and spatial patterns of green infrastructure and development patterns. The results of this research will be helpful for urban planners to prepare green infrastructure implementation guidelines for effective urban flood mitigation.

  • This paper describes the application of the three sustainable design elements for a residential project in the county of Los Angeles, USA. The first design element is the green building design in which a base model will be created using the Autodesk REVIT MEP program for the analysis by Building Information Modeling (BIM) for the energy analysis modeling process to determine the energy savings for each of the recommended design features. The second element is the Low Impact Development design for the site design using specialty material and structural devices for infiltration and recycling of storm water for reuse. The third element is the application of drought tolerant plant species in the site's landscaping design as a means to conserve water. The construction cost associated with the application of these three elements will be reviewed to determine the practicality and effectiveness of this sustainable design approach.
