The New Zealand Green Building Council (NZGBC) is the country’s leading not-for-profit organisation championing the quality built environment. The Council achieves this through setting standards of best practice through green building rating tools; education and training for all areas of the building industry value chain; and providing access to networks, information and resources for our members to lead the market.

NZGBC oversees NABERSNZ , Homestar and Green Star, the award winning certifications for New Zealand homes and buildings.

Green Star is an independent rating system that assesses buildings’ sustainability attributes across a range of criteria. It is the pre-eminent system used to rate commercial buildings in New Zealand. Existing Green Star rating tools are available for offices, education and industrial buildings, and custom tools can be developed for specific one-off projects. Ratings range from 4 Green Star (best practice) to 6 Green Star (world leadership).

Homestar is the comprehensive, national, independent system that rates the health, comfort and efficiency of New Zealand homes, on a scale of 1-10, at both the Design and Built phase. A 6 Homestar rating or higher provides assurance that a home will be warmer, healthier and cost less to run than a typical new home. Homestar ratings are assessed by qualified professionals and certified by the New Zealand Green Building Council. Ratings take into account energy, water, waste, ventilation, health and comfort, and other environmental factors.

NABERSNZ is the industry standard for benchmarking and improving office building energy performance in New Zealand. It is licensed to the Energy Efficiency and Conservation Authority and is administered by the NZGBC.

NZGBC is a member of The World Green Building Council consisting of approximately 75 national Green Building Councils (GBCs), making it the largest international organization influencing the green building marketplace. Globally, GBCs partner with industry and government to transform their building industries through the adoption of green building practices.
