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 |

| Removing the Source of Pollutants | DABv1 | March 2023 | 9 - Indoor Air Quality | Exhaust or Elimination of Pollutants | Link |

Approved Ruling: For the purposes of credit criterion 8.3A - 'Removing the Source of Pollutants' in Green Star - Interiors and 9.3A 'Removing the Source of Pollutants' in Green Star - Design & As-Built, where printing and/or photocopying equipment are present within the building, the Blue Angel certificate issued in accordance with one of the following test standards can be used to demonstrate compliance with the credit criterion:
The standard UL 2819 is recognised in Design & As Built NZv1.1 as a Greenguard certificate and should be issued in accordance with the test standard. Compliant test standards RAL-UZ 171 and GGPS.003. in Design & As Built NZv1.0 are still acceptable. Note: Testing of Emissions in Clause 5.6 of EC-24 requires testing in accordance with RAL-UZ-171 or RAL-UZ-205 and so ECNZ certification also meets the requirements of Credit 9.3 of the Design & As Built NZv1.0 tool. |
