| Summary: | The building sector, due to the significant energy and environmental footprints it creates, needs to adopt sustainable approaches to help prevent global warming and climate change. Sustainable Building (SB) rating systems have been developed around the world as a method to promote sustainability in this sector. Water is one of the most vital natural resources, and is extensively consumed in the building sector. This article examines the coverage of water-related aspects in 11 prominent SB rating systems under the three key sustainability dimensions: environmental, economic, and social, using a comprehensive coverage analysis approach. Findings highlight a wide range of variation between the examined SB rating systems in terms of water attributes being assessed, water assessment criteria used, the optimal number of these criteria, and the weight assigned to them. Results also show that in general, most of the examined systems exhibit low representativeness and comprehensive coverage of major water subcategories and themes related to sustainable buildings. However, some moderate to high comprehensive coverage was found in water attributes that focus on the environmental and social aspects. The results indicate that representative and comprehensive coverage of social-related water attributes are less than that of environment-related water attributes. The results also highlighted the effectiveness of using coverage analysis techniques as a systematic and efficient way to assess comprehensive coverage of water criteria in SB rating systems.
