Examination of the literature on green school rating systems from six countries that have rating systems in place reveals that each of the rating systems has its own theoretical framework and unique features, and the way schools are ranked varies among the systems (Mogensen and Mayer, 2005; Chan et al., 2015). Eco- Schools, LEED for School, BREEAM Education 2008 (BREG, 2008) and the Australian Green Star Education v1 (GBCA, 2015) use a grade rating system; but the Japanese Comprehensive Assessment System for Building Environmental Efficiency (CASBEE, 2012) and the China Society for Urban Studies (CSUS, 2011) use a complete degree-rating system. Even though there are differences in the way schools a ranked, these standards invariably reflect sustainability requirements of environmental protection and the so called ‘‘four savings” of land, energy, water and material (Zhao et al., 2015).
