On this latest episode of How to Build a Better World, our managing editor Tina Perinotto talks to Mathew Nelson – the first Oceania chief sustainability officer at EY – about what’s getting big Fortune 500 companies ticking on the climate question. For someone at the big end of town, leading the sustainability team at a company that’s 300,000 strong globally, he’s remarkably down to earth and happy to share practical insights into the big questions around our transition to low or zero carbon...
NEW PODCAST: On this latest episode of How to Build a Better World, our managing editor, Tina Perinotto, spoke with Paul King from Bentley about how new technology like building information models (BIMs) and digital twins can help designers and engineers make better choices about building design and maintenance. It’s an exciting world that is starting to look a bit like the sci-fi image we read about in stories about gaming or fiction. A parallel universe in cyberspace that we can – hop...
In our latest podcast, our managing editor, Tina Perinotto, spoke with Alan Pears about how he got started in the sustainability and energy efficiency space, and the “big challenge ahead of us”. Alan Pears is probably Australia’s favourite, most trusted and reliable “go-to” authority on energy efficiency. And no wonder. He’s been around since the dawn of the environmental movement in the 1970s and initiated many of its big leaps forward. While a lot has changed since then, Alan’s...

In our latest podcast, our managing editor, Tina Perinotto, spoke with Dan Hill all about his new role at Melbourne University’s School of Design. Dan Hill’s got a bit of a fan club in Australia. So there was no surprise that the announcement in April that he was to be director was well received. (No pressure, Dan.) It’s a job that’s lured him back to Oz after more than 10 years away, during which his City of Sound blog kept tabs on his projects in Scandinavia, the UK and Italy. M...

As a senior research fellow at Deakin Univers...
On our latest podcast, our managing editor, Tina Perinotto, spoke with Beck Dawson, who has been Sydney’s chief resilience officer since 2015. Her role basically involves worrying about the potential disasters that might befall Australia’s biggest city, and how to build resilience in the community… just in case. It’s a big job. In Beck’s case it involves 33 councils in Sydney as well as state government, business and the community, and plenty of links to resilience experts in other cities a...

Paul headed up his company Exergy fo...
Infrastructure work is going regional – in water, sanitation, roads and bridges – says Kaushik Chakraborty senior vice president, Asia Pacific & Japan with Bentley Systems in this podcast.

The trend is reversing the previous super trend that had captured demographers for decades. Host: Tina Perinotto Produced by: The Fifth Estate The Fifth Estate website: www.thefifthestate.com.a...

After 30 years Dave Higgon reckons he’s the longest serving employee relations manager in Australia. He started his career as a bricklayer for his father, before taking up small subcontracting work on the New South Wales north coast and into Queensland. In the early 80s, Higgon became an organiser for the Building Workers Industrial Union, where he developed a strong interest in social justice issues, then joined Multiplex, where he “inherited” responsibility for dealing with social pro...
Nathan Hage is neither a developer nor an energy expert, nor anything else you might think would be crucial to retrofitting a group of 45 flats in Sydney’s inner south with solar and EV charging. He works in logistics, but the one qualifier that he firmly holds is that he’s a resident of the Zinc Apartments, and perhaps through his enthusiasm, the job fell to him to manage this ambitious project. Host: Tina Perinotto Produced by: The Fifth Estate The Fifth Estate website: www.thefifthe...
