This study reveals the status, perceptions, and future directions associated with green building within construction-related companies. A survey research method was used to capture current experience levels and capabilities of companies with regard to green construction. Expectations and perceptions about the future of the construction industry with regard to green building were obtained from construction-related companies recruiting from the Myers-Lawson School of Construction at Virginia Tech from 2006 and 2008. The findings of this study support the growing importance of green building as a component of the whole construction market and provide a benchmark against which to measure future changes in the industry over time.

With the mounting concerns over environmental issues, green construction is gaining a place in the global construction industry. However, rare research has been conducted to analyze green construction projects, especially in the aspect of project schedule performance. As a result, this study aims to investigate the degree of project delay in green building construction, analyze the factors affecting schedule delay of green building projects, and finally provide recommendations to improve schedule performance of green building project. To achieve the objectives, a comprehensive literature review was carried out, followed by a survey conducted with 30 companies that provided data from 220 traditional and 96 green building projects. The analysis of the responses identified that 15.9% of the traditional building projects were delayed while 32.3% of the green building projects were completed behind schedule. Furthermore, the amount of the delays in green building projects was an average of 4.8% of their planned schedule. The top 5 critical factors that can cause delay in green building projects were identified as: (1) speed of decision-making by clients; (2) speed of decision-making involving all project teams; (3) communication/coordination between key parties; (4) level of experience of consultants; and (5) difficulties in contractors' project financing. Lastly, a list of recommendations was introduced, aiming to reduce schedule delay in green building construction projects based on the observations. This study will serve as s a base for further research on the enhancement of green building project schedule performance.

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.

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.

In recent years, the demand for green buildings is growing fast due to legislative and social pressures. Construction organizations, which play an important role in promoting building industry growth, are facing with challenges on how to adapt themselves to enhance sustainability of the buildings. In this paper, the green value chain and system frameworks, an extend application of Porter's value chain and system models, are introduced. Based on deep analysis of the green value chain and system frameworks, a revolution model for construction organizations towards green building is created. Management factors critical for a successful green building project, at the firm and project organization level, are extracted. Furthermore, external critical relationships are also identified. Fully understanding of these management factors and the model can help and enable practitioner to know what new capabilities should be deployed and developed in the long run for maximizing sustainability.

The construction of green building has distinct charicteristics by work classification by applying green technologies. Thus if the new technologies are applied to construction, unskiiled worker can experience construction time delay, reconstruction occurrence and quality decrease because of mistakes during the construction and work progress. For this background, we establish the work progress manual to secure quality and performance during the construction phase of green building and provide method to be used in the construction sight operation.

Green building information used by the AEC industry is diverse and extensive), causing difficulties for personnel regarding the collection and utilization of information in the form of inaccurate searches about related laws, inefficient management of searched information and overlapping works. Therefore, this research aims to propose a law search system utilizing metadata for more accurate and efficient searches of green building information. The proposed system is expected to contribute to improve productivity of construction projects by reinforcing the accuracy and efficiency of searches for the collection and utilization of green building information.

In the United States, the implementation of the LEED green building rating system has dramatically changed the construction industry to motivate construction participants to employ green building approaches into projects. The objectives of green building rating systems are to achieve the triple bottom line benefits including economic, social and environmental benefits that are able to not only provide an excellent amenity to building users, but also to reduce environmental problems associated with buildings and accomplish financial benefits. Since the implementation of green building features has many benefits, the purpose of this study is to identify occupants' satisfaction of green building and the transformation of occupants'' attitude toward sustainability by conduct an in-depth case study of the cutting-edge green building project located in Atlanta, GA, USA. Based on this case study, it is possible to suggest construction participants in Korea to identify how green building can improve occupants'' satisfaction of the building and change their attitude toward sustainability.
