NZGBC is committed to setting standards of best practice and leadership through the development of environmental tools for buildings in New Zealand. Green Star is a comprehensive, national, voluntary environmental rating scheme that evaluates the environmental attributes of New Zealand's buildings using a suite of rating tool kits developed to be applicable to different building types and function.
The tools are developed by the NZGBC in partnership with the building industry to:
The Green Star suite of rating tools was designed to match the key phases in a building life cycle:
Design > Built
The tools address the needs of specific building types, such as office buildings, industrial buildings and education buildings, in the design phase and following construction, in the Built phase.
The current tools assess the environmental impact that is a direct consequence of a building's site selection, design, construction, and maintenance. The framework has eight separate environmental impact categories plus an innovation category.
Credits are awarded within each of the categories based on the building's environmental merits in a range of areas and 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.
