A Study on the Direction of Revision for Green Building Certification Criteria on Office Building - Focused on the Comparison with LEED and BREEAM -

Abstract

The objective of this study is to propose the direction of revision for Green Building Certification Criteria(GBCC) on office building with comparison analysis to LEED(USA) and BREEAM(UK). Korean GBCC has been developed for both residential and non-residential building, and GBCC for office building has been becoming a reference for other non-residential building. In this paper, Korean GBCC for office building was reviewed to find out current problems, and compared to foreign certifications to propose improving points for sustainable architecture with reliability. Before compared with LEED and BREEAM, the definition and the design methodology of sustainable building were reviewed and objectives and practical contents of GBCC were figured out Korean and foreign certification criteria have been analyzed as TBL. The result shows that item number and flexibility of GBCC were not sufficient to become a guideline for architects. Korean and foreign certification was focussing on environmental sustainable matter. Social sustainable matter were not widely considered and mainly focussed on improvement on interior environment. Consequently, new contents on social aspects were required in to current GBCC for sustainable architecture. Many of Korean architects were putting effort on achieve green building certification to accomplish sustainable architecture. GBCC could be a role as guideline well as certification criteria. More contents on social aspects, detailed certification standard, and flexible items are needed for better system on sustainable architecture.
