Sustainability performance assessment of green roof systems using fuzzy-analytical hierarchy process (FAHP)

Green building practices are gaining in popularity as a means to mitigate environmental and human health impacts of construction and development. Green buildings incorporate environmentally responsible and resource-efficient technologies to reduce environmental impacts over their life cycle. Recently various environmental assessment methods have been developed to assess the environmental performance of green building technologies. Methods developed to date are, however, insufficient for accurate quantitative estimation and evaluation of triple-bottom-line (TBL) sustainability performance objectives (i.e. economic, environmental and social) in the context of green building technologies. Moreover, selection processes for these technologies often involve significant uncertainty and subjectivity. As a result, currently available approaches to estimation of sustainability performance over a technology's life cycle may be unreliable and misleading. This paper aims to remedy some of the shortcomings in current a...
