Building Rating Systems
The New Zealand Green Building Council’s Green Star NZ rating system is used to assess the environmental impact of offices against eight environmental impact categories, plus innovation. Within each category, points are awarded for initiatives that demonstrate a project has met sustainable development objectives during the different phases of a building’s development (design, fit-out and operation). Points are then weighted and an overall score is calculated, determining the project’s Green Star NZ rating – 4 Star = Best Practice, 5 Star = New Zealand Excellence, and 6 Star = World Leadership.
Although a relatively new initiative, Green Star NZ is being widely recognised and accepted by the construction industry. Owners, operators, and their clients and tenants are being driven by the desire for “green certification” of a building, which will provide opportunities for the sustainable attributes of cement and concrete to be recognised.
