Products & materials
We have a FREE webinar which discusses how Products and Materials can be used in Green Star (and Homestar) projects. It also covers Eco-labels, Environmental Product Declarations (EPDs) and other related topics. Click on the red link to the right on the following link. You will have to fill in your details but the webinar is FREE. You are encouraged to view it here
We are frequently asked about how a product or building material can become "part of" our rating systems.
Green Star rates whole buildings, rather than building components such as products and materials. Under Green Star, materials that have certain attributes can receive points that contribute to the overall score of a rated building.
NZGBC does not test, review or certify products or materials. Instead, we utilise the work of third-party certification bodies and eco-labels. They test and carry out environmental assessments of products and materials that relate to the Materials category and Indoor Pollutants credit. These organisations are independent of manufacturers, suppliers and the NZGBC; they identify products that are environmentally preferable compared to similar ones on the market.
NZGBC also recognises products that are reused, have high recycled content, have stewardship programmes, and have low emissions of Volatile Organic Compounds (VOC).
If you are a product and/or materials supplier and you would like your product to be used in a Green Star project, you are encouraged to have the product either certified under one of the eco-labels listed on this page and/or generate an Environmental Product Declaration (EPD). For further information on EPDs, please read the following article.
Environmental Product Declaration: a level playing field for construction products
When certain products or materials contribute towards points in a Green Star rating, this creates valuable marketing opportunities for manufacturers and suppliers. NZGBC works with our product members to help them communicate how their products fit within Green Star.
