Comparative Analysis of LEED, BREAM, and DGNB as Green Building Rating Systems for New Construction Category. Case Study: Greenship

Environmental issues such as high carbon emissions from building activities increased the urgency of green building application. The system that is used to assess the performance of green buildings is called Green Building Rating Systems (GBRS). GBRS have spread in various parts of the world, from Europe to Asia. However, existing studies on comparisons of GBRS are limited to weight analysis of the most recent version of manuals. Therefore, the purpose of this paper is to fill the gaps in the comparative studies of the Green Building Rating System, especially regarding changes in indicators, underlying issues, and potentials for future developments.

This writing specifically contains a comparative analysis of the International GBRS (BREEAM, LEED, DGNB) with the GBRS from Indonesia (Greenship). LEED-based comparisons were made by reviewing the indicators and sub-indicators of each GBRS from the instruction manuals. The result of this comparison shows that the disclosure of the number of points is a crucial aspect in the assessment process. This study also shows that the high cost of certification does not always indicate a for-profit institution. In addition, every GBRS that is compared has room to grow, especially from other GBRS.
