Our annual Products and Materials Forum offered a packed programme with useful updates for product and material suppliers, designers and specifiers. Attendees got an in-depth briefing on how products and materials are recognised in the Green Star and Homestar rating tools.
Jack Bright, Scheme Manager of the Envirocon Product Stewardship Scheme
New Zealand produces an estimated 270,000 tonnes of waste ‘wet concrete’ each year. It’s enough to build seven sky towers. Envirocon is New Zealand’s first construction related product stewardship scheme Accredited by the Minister for the Environment. We’re reimaging how waste concrete is dealt with by upcycling this resource in to innovative concrete products such as the Stonebloc and Interbloc wall systems. View his presentation

Andrea Davison, Technical Manager – Special Projects at the New Zealand Green Building Council gave us an overview of how products and materials can help a project achieve innovation points in Green Star through Life Cycle Assessment, Environmental Product Declarations, designing for waste minimisation and best practice waste management.

Thorough ▪ Comparable ▪ Comprehensive ▪ Robust. These are key features of an Environmental Product Declaration (EPD). Together they allow end users to fairly assess the impacts of different products, similar to a nutrition label.
However, EPDs are only one of the tangible outputs from undertaking a Life Cycle Assessment (LCA) study. It is the process itself that creates most business value, by contributing to increasing revenue, reducing cost, enhancing brand and reducing risk.
Barbara Nebel, Managing Director, thinkstep Ltd shared industry examples of how LCA can be a catalyst for innovation, identify cost and efficiency opportunities, identify risk in the supply chain, and support sales process. View her presentation
Thanks to its uniform and predictable properties, steel components are essential elements for engineers when designing structural systems for seismic loads and resilience.
Nick Carman, Structural Engineer, Holmes Consulting discussed the many ways steel is used in seismic systems, both big and small, and how this can be considered in the new Green Star Innovation Challenge for Earthquake Resilience. View his presentation
With around half a million tonnes of construction and demolition waste going to landfill in Auckland each year, now is the time to take another look at those demolition materials that would otherwise go in a skip. Buffie Mawhinney and Mark Roberts from Auckland Council presented two case studies where demolition materials have been reused with some unexpected results. View their presentations
