Green Star Technical Clarification Rulings
Technical Clarifications for Green Star represent our answers to Technical Questions submitted by projects, and provide further guidance and reference to others. The list is regularly updated.
There are two types of Technical Clarifications listed in the table below:
General Clarifications
These are extensions to the guidance provided in the Submission Guidelines. They clarify and sometimes supersede the original Credit Criteria or
Compliance Requirements. General Clarifications set precedent for future project teams to follow. Should a project team wish to apply a general clarification to its project, there is no requirement for further Technical Questions to be submitted. NZGBC Assessors will also use them as precedents to assess submissions.
Project Specific Clarifications
These are published as references for other projects but, unlike General Clarifications, they do not set precedent. They often relate to special
situations where multiple prerequisites exist for a particular project and are less likely to reoccur to another project. Therefore, rulings set for Project Specific Clarifications are often conditional and will likely vary for other projects. Each project still needs to submit its own Technical Questions and provides evidence relating to its own building in order to have a similar ruling approved for that specific building.
Should you wish to apply any Technical Clarification for legacy rating tools to your projects, please submit a Technical Question to the NZGBC to
explain why and how it applies. You can access the online Technical Question form here
| Technical Question Title | Tool Version | Date Released | Credit Name | Sub-credit Name | TC Link |
|---|---|---|---|---|---|
| Clarification of Credit 25.2 - Stormwater and Pollution | DABv1 | April 2020 | 25 - Stormwater | Stormwater Pollution Targets | Link |
|
Approved Ruling: The credit introduction states “25.2 STORMWATER POLLUTION TARGETS Where criterion 25.1 has been achieved, one (1) additional point is awarded where it is demonstrated that all stormwater discharged from the site meets the required pollution reduction targets for the identified contaminants of concern when compared to untreated runoff in accordance with the following requirements.” Table 25.1 Pollution Reduction Targets lists several pollutants including Zinc and Copper. It has been determined that if a project team can provide evidence as to why the building and its associated site will not generate these pollutants they are not required to include them in the model. For example, if it can be shown that a steel roof has been appropriately coated to remove the likelihood of zinc runoff than the project would not need to include Dissolved Zinc in the model. Please submit a TQ to NZGBC with supporting documentation if this is to be pursued. |
