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

| C&D Waste Points when Delivering an Integrated Interiors and D.A.B Building | DABv1 | April 2021 | 22 - Construction and Demolition Waste | Construction and Demolition Waste | Link | |||||

Approved Ruling: How do I calculate C&D Waste points when delivering an integrated Interiors project within a Design & As Built building? Fixed Benchmark Pathway (22A) Projects teams delivering a Green Star rated Interiors project within a Green Star Design & As Built rated base building may aggregate the base building and fitout construction and demolition waste to determine the maximum waste allowance based on the combined GFA and NLA. Up to one (1) point for the base building (GFA) and up to three (3) points are awarded for the fitout (NLA) where the construction and demolition waste going to landfill meets a fixed benchmark, defined in kilograms of waste per square metre in the Construction and Demolition Waste Fixed Benchmark pathway. Points are awarded based on the maximum waste allowance calculated using the combined GFA and NLA: (GFA x targeted waste benchmark) + (NLA x targeted waste benchmark) = cumulative waste total. Points are awarded in accordance with the waste benchmarks for a typical building, and typical fitout as per the table below; Design & As Built (base building) Interiors (fitout)
Please note only one innovation point is available and that points may be pro-rated in between benchmarks. Percentage Benchmark Pathway (22B) Projects teams delivering a Green Star rated Interiors project within a Green Star Design & As Built rated base building may aggregate the base building and fitout construction waste when targeting a percentage benchmark. Up to one (1) point for the base building (GFA) and up to one (1) point for the fitout (NLA) is awarded where at least 70% of aggregated base building and fitout waste, generated during construction and demolition, has been diverted from landfill (waste reported in kilograms) as defined in the 22B Construction and Demolition Waste - Percentage Benchmark pathway.
