Also analyze the characteristics of BREEAM, LEED and G-SEED certification items. As a result of examining the certification items of G-SEED, BREEAM and LEED, G-SEED has a high proportion of local items. This study proposed the G-SEED global version. Items for definition of local standards are suggested to be self-define. Items for local characteristics (climate and vegetation) are suggested to change their criteria. Items for contents of local standards and laws are able to be changed according to the characteristics of each country. Global items are maintained. The results of this study can be used as basic data for the G-SEED global version.
