 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
Contemporary of Future-Proofed EV Infrastructure DABv1, DABv1.1 October 2022 17 - Sustainable Transport Low Emission Vehicle Infrastructure
Approved Ruling:

The NZGBC defines electric vehicle charging infrastructure as the provision of a standard domestic, commercial or industrial power outlet, or wiring to enable the future installation of electric vehicle charging equipment without the electric vehicle charging equipment itself being installed at the time of practical completion, thus making the project electric vehicle ready in the future.

 

For projects registered under the Green Star - Design & As Built v1.1 and earlier versions, 5% of the car parking spaces provided with the electric vehicle charging infrastructure as a minimum must have:

  • At least 2 car parking spaces provided with an electric vehicle charging unit with a dual-port; or
  • An industry-standard socket outlet to facilitate recharging an electric vehicle;

and;

  • Has communications capabilities that may be used to enable a load management system.

This TC applies only if the calculation requires two or more EV spaces. For small projects requiring one EV space, a single port charger can be installed. This charger must comply with the bottom two bullet points above. If two or more spaces are required, the first two must meet the three bullet points above, and additional spaces only need wiring for future chargers.
