5. LEED-EB and Green Globes CIEB: Rating Sustainable Reconstruction

摘要

When green building rating programs were launched about a decade ago, their pri mary objective was to reduce environmental impacts from new construction. Over time, as the U.S. Green Building Council's LEED system and the Green Building Initiative's Green Globes program evolved and expanded, the focus started shifting to exist ing buildings, either for ongoing sustainable operations and maintenance-office fitouts, hotel room renovations, lighting upgrades, etc.-or for more wholesale repurpos ing-more elaborate reconstruction, adaptive reuse, reno vation plus addition, etc. In recent years, certifications for existing buildings have rapidly outpaced those for newly built ones, according to both the USGBC and the GBI.
