The A1 building at Auckland University of Technology (AUT) North Campus is the spearhead of AUT’s ambition to become the most energy-efficient university in New Zealand. Designed by Jasmax, A1 will be AUT’s lowest carbon and most energy efficient structure, building on a legacy of highly sustainable development for this ‘University of a Changing World’.
That commitment to sustainability and waste reduction is carried through all aspects of the project, including the construction process.
‘I think it is widely understood that construction and demolition make up around 50 per cent of what goes into our landfills,’ says Annie Day, Group Environmental Manager at Naylor Love. ‘Our ambition with the AUT North Campus project was to have a zero-waste worksite, and obviously recycling plays a huge part in that.’
Scaling up the programme
’Both AUT and Naylor Love were looking to lead the way in keeping waste out of landfill, and Auckland Council came in with funding for the project,’ says Aidan Hill, GreenStuf’s Technical and Sustainability Manager. ‘With GreenStuf going into all the external walls, incorporating the Takeback programme ensured product stewardship for all the insulation.’
After its initial trial at Manurewa High School’s new Business Hub in 2020 proved a success, the GreenStuf Takeback scheme was implemented on a much greater scale at the A1 project, an entire new build using sustainable engineered timber, along with the full refurbishment of an existing four-level building.
‘One of the main things we learned on the pilot programme was that the subcontractors have to be on board,’ says Annie. ‘It’s a new world for everybody, and the Takeback programme is ground-breaking in showing how effective recycling can be for the construction industry. It just needs the right kind of training for the teams on site.’
