Specify Sustainable Building Materials with NBS Chorus The NSW and federal governments will invest up to $2 billion over 10 years to reduce emissions in New South Wales—making it the most comprehensive, fully-funded plan in Australia. The production and use of construction materials is responsible for 10 per cent of the state's total annual emissions. Given the manufacturing of traditional steel, concrete and aluminium produce high levels of carbon dioxide, cutting these levels is a priority in the state government’s plan to reach net-zero emissions by 2050. And when it comes to innovative technologies NBS Chorus is at the forefront as the...

In fact, AC is booming in nations across the world: it’s predicted that around two thirds of the world’s households could have an air conditioner by 2050, and the demand for energy to cool buildings will triple. But unless the energy comes from renewable sources, all that added demand will generate more greenhouse gas emissions, which contribute to global warming –...

How to print a building: the science behind 3D printing in construction Building sites are going to look a bit different, in the future. Shutterstock. Seyed Ghaffar, Brunel University London It’s often claimed that 3D printing – known in the trade as “additive manufacturing” – will change the way we live. Most recently, a team from Eindhoven University of Technology announced plans to build the “world’s first” habitable 3D printed houses. But it’s one thing to build small, prototype homes in a park – it’s quite another to successfully use additive manufacturing for large scale projects in the construction sector....
