For example:
LEED Canada – Regional Priority Credit “Durable Building”
To minimise materials use and construction waste over a building’s life
resulting from inappropriate material selection or premature failure of
the building and its constituent components and assemblies.

• Beyond what is currently defined in Green Star
• Broader sustainable development principles: social,
economic and cultural
![Page 13: Green Star Rating System - nzgbc.org.nz](https://reader034.fdocuments.net/reader034/viewer/2022052105/6286d6c8ba0ed66dfc365cc3/html5/thumbnails/13.jpg)
Open-ended subject areas which:
• Identify an issue for research and exploration but don’t
specify how to achieve it
• Offer minimum requirements for evidence
• Reward projects for incorporating strategies that address
the identified issue.
![Page 14: Green Star Rating System - nzgbc.org.nz](https://reader034.fdocuments.net/reader034/viewer/2022052105/6286d6c8ba0ed66dfc365cc3/html5/thumbnails/14.jpg)
• Adaptation & Resilience
• Contractor Education
• Culture, Heritage & Identity
• Financial Transparency
• Market Intelligence & Research
• Marketing Excellence
• Material Life Cycle Impacts
• Social Return on Investment
• Environmental Product Declarations
• Earthquake Resilience
• Circular Economy (in development)

AIM:
To assess and reduce the environmental
impacts of building materials for the
whole building over its entire life cycle.
![Page 16: Green Star Rating System - nzgbc.org.nz](https://reader034.fdocuments.net/reader034/viewer/2022052105/6286d6c8ba0ed66dfc365cc3/html5/thumbnails/16.jpg)
Criteria:
1 point is available where a whole-of-building,
whole-of life cycle assessment for the project is conducted.
Up to 5 points are available where the results are compared to a reference case.
Points are awarded based on the extent of environmental impact reduction in six
categories when compared to the reference building.
An additional point is awarded where the LCA includes reporting against 5 additional
impact categories.

AIM:
To encourage the use of products and
materials for which life-cycle information
is available.
“EPD, underpinned by life cycle assessment (LCA), can provide an optimal
approach to a more robust and consistent evaluation of the environmental
performance of New Zealand buildings across the life cycle.” – BRANZ report
![Page 19: Green Star Rating System - nzgbc.org.nz](https://reader034.fdocuments.net/reader034/viewer/2022052105/6286d6c8ba0ed66dfc365cc3/html5/thumbnails/19.jpg)
Criteria:
Up to 2 points are awarded where a minimum of 2 permanently installed products
hold a current EPD. The benchmarks for achievement are as follows:
• 1 point where 2 different products hold current EPDs
• 2 points where 6 or more different products hold current EPDs
• All products must be sourced from different manufacturers.
• Product-specific EPDs are recognised as one whole product.
• Industry-wide EPDs are valued as one half of a whole product
• At least one product (for one point) or two products (for two points) must be a
product recognised within the Green Star Materials category credits.

AIM:
To encourage and recognise projects that
employ strategies to mitigate the impact
of earthquake and seismic movement
over the life of a building.

AIM:
To encourage design for waste
minimisation, adoption of a circular
economy model, and best practice waste
management.
