 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
Minimum Requirement as Pre-requisite to Other Credits (credit 22.2) DABv1 May 2021 22 - Construction and Demolition Waste Reporting Accuracy
Approved Ruling:

This TC is released to supersede the previous TC issued in May 2020 for credit 22. 

The Design and As-Built and Interiors tool, Construction and Demolition waste Credit 22 has a minimum requirement that must be met BEFORE the other credits can be approved.

The “Reporting Accuracy" credit criteria states the following: “The minimum requirement is met where the waste contractors and waste processing facilities servicing the project demonstrate compliance with the Green Star Construction and Demolition Waste Reporting Criteria.” Environmental Choice New Zealand (ECNZ) issued (EC-59-19) Construction & Demolition Waste Services specification (found here https://environmentalchoice.org.nz/specifications/ec-59-19/ ) fulfils the Reporting Criteria minimum requirement.

Therefore, if all the associated waste contractors and waste processing facilities are awarded a licence under this specification then the project meets the minimum requirement for this credit.  

Projects using ECNZ-licensed waste contractors also qualify for 1 credit related to 70% diversion from landfill, provided the ECNZ audit is completed withing two months after Practical Completion of the project in accordance with clause 6.3 c) of EC-59-19.
