Green Building Evaluation System


New Construction
At this point, I will try to compare the criteria for achieving credits between USGBC LEED rating system and Indonesia GREENSHIP.  In the GREENSHIP, there are two rating points achievable—Design Recognition Assessment (DR) and Final Assessment (FA).
Indonesia GREENSHIP has also referred to LEED system as its fundamental basis.  For each parameter, there will some criteria and from both systems, there are some slight differences in the checklist form.  However, the criteria formed are typical.  Below table is briefly summarizing the comparison of those two rating systems.

The grayed out rows refer to applicable bonus that can be implemented in the project.  For the certification system, GREENSHIP also follows the method that is used by LEED.  It seems that the achievable points are different in each criterion therefore the point assessment are also different.  In LEED, the bonus points can be obtained in two indicators, i.e. Innovation and Design and Regional Priority.  Meanwhile, the bonus point for GREENSHIP can be obtained only from Energy Efficiency and Conservation indicator.  Since this is the bonus, the GREENSHIP system gives bonus point to the installation of on-site renewable energy system.

The design recognition is intended to the design phase of the building.  Here, the project has not been executed.  Eventually, it can be seen from the specific guideline in the portion of Materials and Resource Cycle.  The all materials criteria might not be counted since this is still only the design.  It means the DR system can be extended to the FA system after the project has been completed.

What we can conclude that, GREENSHIP adopt the LEED system in the point of parameters used.  However, the assessment points are different each other.  This comparison can be useful as the comparison of rating system assessment that is adopting LEED system as its fundamental.
