Buildings and their construction account for as much as 20% of New Zealand's emissions. We're on a mission to change that.
We know with your help we can transform the way our commercial buildings are designed and built, dramatically
reducing our carbon footprint and improving the health and wellbeing of our people.
To help make it happen we run the internationally recognised Green Star certification.
“Green Star fosters smarter building, more resource efficiency, energy and water savings, lower running costs and a healthy work environment for everyone”
- Tony Moore, Christchurch City Council
Created by our friends at Green Building Council Australia and adapted for Aotearoa, Green Star is Australasia's largest voluntary and truly holistic sustainability rating system for buildings, fitouts and communities.
Green Star ratings are available for every commercial building type; from schools and hospitals, to office buildings, shopping centres, and industrial warehouses. Homes are covered by our Homestar ratings.
A building or community certified to Green Star has proven it meets best practice sustainable design and build benchmarks. With transparent, robust, and independent assessment we work to combat the risk of 'greenwashing' and distinguish those who are truly doing the mahi.
Taking up a voluntary Green Star certification demonstrates leadership, innovation, environmental stewardship and social responsibility.
Green Star continues to evolve in collaboration with the industry to ensure it incorporates new thinking, best practice, and meets the needs of the market.
There's a lot to consider when it comes to creating healthy, sustainable spaces. Green Star takes a holistic approach, considering not just direct environmental impacts like materials or water use, but broader transport, indoor environment quality, and management implications of a project.
Certifying with Green Star can help reduce not just your carbon footprint but save you money, create a healthy productive place for people, and build a better future for us all.
Green Star can also be used on large scale community development projects. Green Star - Communities rewards social sustainability initiatives alongside environmental measures to ensure the creation of prosperous, connected, truly liveable neighbourhoods.
How it works
Green Star assesses the important elements of a project's sustainability across key categories. Each category includes benchmark for a lower-carbon, healthy project. Points are awarded for successfully meeting these criteria. The total number of points awarded decides the final Green Star rating.
