Using a suite of rating toolkits developed for different building types and functions, buildings are evaluated to assess the environmental impact of their site selection, design, construction, and maintenance.
- The Green Star suite of rating tools was designed by the NZGBC in partnership with the building industry to match the key phases in a commercial office building life cycle – from offices and retail centres to hospitals and public buildings. They’re used to:
- Establish a common language and standard of measurement for green buildings
- Promote integrated, whole-building design
- Raise awareness of green building benefits
- Recognise environmental leadership
- Reduce the environmental impact of development
Credits are awarded within each of the categories based on the building's environmental merits. They take into consideration the unique development requirements and impacts of each sector.
Points are then weighted and an overall score is calculated, determining the project's Green Star rating.
Possible Ratings:
- 4 Star Green Star Certified Rating (score 45 - 59) signifies 'Best Practice'
- 5 Star Green Star Certified Rating (score 60 - 74) signifies 'New Zealand Excellence'
- 6 Star Green Star Certified Rating (score 75 - 100) signifies 'World Leadership'
