It is well known that the building sector plays an essential role in Chinas total energy consumption and promoting green building could be one solution to reduce the energy consumption and overall emissions of greenhouse gases.In the whole supply chain of the building sector,there are various parties or stakeholders involved in,e.g.the developer,architect,engineers(mechanical/electrical/civil),contractor,consultants,facility company,owner etc.Thus,it becomes important to understand the relationships among these stakeholders,the mechanisms of motivations and initial barriers towards green buildings.This paper presents a case study of a building in the City of Shanghai with the highest rating in Chinas green building standard.The building integrates office and lab spaces.Several stakeholders who worked on this office building project were interviewed,including staff from the developer,architect,engineer,facility manager and two users.The same set of interview questions were asked but modified according to the interviewees background.Then,using a system dynamics approach,a causal loop diagram was built based on interview materials using Vensim(R).The results are expected to produce a holistic picture of efficiently promoting green buildings in China by listing the locations of barriers along the supply chain and possible solutions.In the future,more case studies are going to be explored and comparison with buildings in the UK will be carried out.
