Two big construction projects in New Zealand aim for our Green Star certification, the Zero Carbon Bill moves a step closer to becoming law, global renewable electricity supplies are tipped to grow 50% by 2025, the largest 3D printed building in the world has opened in Dubai, and momentum increases for building prefabricated homes in NZ. These stories and more in our regular round up of green building and climate change news from here and around the world.
A new hospital building planned for Taranaki is aiming for a 5 Green Star Certification, NZ Doctor reports. The head of the Taranaki DHB says hospital buildings are the single greatest government building energy consumer in New Zealand so the project represents an opportunity to reduce the DHB’s carbon, water and energy footprint. The 5-star rating will also help improve the wellbeing of the building's users, reduce how long patient stay and improve staff productivity.
