FUZZY GREEN CONSTRUCTION FOR MEASURING ENVIRONMENTAL PERFORMANCES OF CONSTRUCTION PROJECTS

In the last three decades the Indonesian construction industry has gradually answered to demands for more environmentally responsible industry, where sustainability initiative has evolved from sharing idea amongst academia and professionals to real on-field implementation of green concept. While the application of the concept of green buildings has become a common practice in the building and housing sector, efforts to expand the application of green principles and sustainability to also cover the stages of the construction process only proceed slowly. One challenge is the lack of understanding from construction practitioners and project owners about the benefits of the green process, which is caused by the unavailability of metrics to assess the performance of green measures in construction projects. Such condition makes it difficult for the construction industry to promote the idea of green construction. This paper will discuss the development of instrument to measure the environmental impact of construction process in building construction process. This instrument is arranged in the form of a hierarchical structural system that addresses seven environmental aspects of construction work, that adopts fuzzy concepts to better accommodate human subjective assessments of resource use and other practical aspects of construction during the construction implementation process.
