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 download the Technical Question form here

The C and D Waste Reporting Criteria requires Waste Contractors to provide weigh bridge receipts as part of the audit to receive the Compliance Verification Summary. The C and D Waste Reporting Criteria does not require Reprocessing Facilities to be audited or to have a weigh bridge (please see the C and D Waste Reporting Criteria definition section for further clarification of these terms). Waste contractors transporting C and D waste to reprocessing facilities which do not have weigh bridges can provide alternative methods proving the load from the construction site goes directly to the reprocessing facility. One way of proving this can be a GPS track of the waste contractor vehicle from the construction site to the reprocessing facility, such as E Road. A Waste Contractor taking material to a Waste Processing Facility will require weigh bridge receipts as per the C and D Reporting Criteria. |
