Stan Krpan is the CEO of Sustainability Victoria, an organisation all about information, advice and support to tackle climate change. The whole world needs to get to zero emissions within a next few decades and there needs to be partnership between government and private organisatoins - SV are providing the vision and help for Victorians to do their bit.

Tony Frencham is a group managing director at Worley Parsons, being responsible for execution and planning for power and new energy and leadership for the global energy transition. Fossil fuels have lifted many of the world out of poverty and has helped lifted the standard of living of the Western world our ancestors couldn't even imagine. But there are new pressures today however, and we are in the midst of a major shift towards renewables in response to our new global challenges.

Martin Powell is the CEO of the Institute of Structural Engineers, and former Executive of the UK Concrete society. The role of the engineer is changing rapidly, and the one who is competent is most likely the one to stay relevant - the Institute being the largest membership organization in the world, dedicated to the art and science of structural engineering.

Tina Perinotto is managing editor, publisher and founder of The Fifth Estate, an on-line newspaper for green buildings and sustainable cities, established in 2009.

In this episode we talk about: - Connecting cities with fast rail - How automation will effect white and blue collar jobs - The worlds tallest tower, Kingdom tower to be integrated as a vertical city, a virtual reality theme park in China, and building smart utopian cities from scratch in Jeddah

It has been almost 12 months since I started the show, and I think it has come along way since the first interview with Anthony Sprigg. Thank you for listening!

Danielle Tensley Tingley is a Professor of Architectural Engineering at the University of Sheffield, her research focuses on how to reduce the embodied carbon of our buildings. Today, cement alone accounts for 8% of the world emissions - which is actually more than cars! If we are to move to a low carbon economy, we inevitably won't be able to stop just at operational energy, we will need to also find the methods to reduce embodied energy down to zero also.

David Allen is arguably the world leading productivity consultant, and author of the best selling book Getting Things Done. When you don't have an effective productivity system, you almost always feel like you should be doing something else. Allen shows that the consistent unproductive preoccupation with all of the things we have to do, is the single largest consumer of time and energy. That most lists people create, are a big blob of undoability.   

Vadim Smakhtin is the co-founder of Chronotope, who better help us understand the urban environment through advanced analysis of data, in space and time. One capability of the technology, is to take information such as our social media, put them through certain filters, and then be able to measure emotional reactions to the time of day and space.

Aarni Heiskanen is a construction innovation agent, and the author of the award winning blog, AEC Business. Typically, big construction companies will try and avoid failure, but at the cost of innovation. Aarni spends his time today consulting big construction companies on how take advantage of the potential disruption that is on the horizon.

Jon Hirshtick is the founder of Solidworks, and more recently the CEO and founder of Onshape, who are innovating in the CAD space. Jon and his colleagues noticed traditional CAD applications had a few flaws and have built a new service from the ground up, that is perhaps more suitable for projects today. 

Paolo Bevilacqua is the head of sustainability at Frasers Property. Frasers has the ambitious goal of getting all of their developments to carbon positive within ten years. This does not come without its challenges. Although there are many unknowns that they need to deal with along the way, but Paolo shows us that carbon positive is not only possible, it is also preferable economically.

Jessica is the founder and CEO of Neighbourlytics, who powered by big data, gives insights to the unique social identity of neighbourhoods. We build places for people to go to, and hopefully enjoy and interact with the space. Until now, there has been no way of measuring the social value of a place.

Nick Hewson is the design manager of Xlam, who specialise in the design and production of cross laminated timber. Steel and concrete have been the preferred construction materials, that haven't been challenged for a very long time - until now. CLT arrived and in many cases, can provide a better solution to traditional construction. It is sustainable, quicker to build and can even boost productivity.

David is the CEO of Aerofarms, the world leaders in Vertical Farming technology. The worlds population is growing and the agricultural land on the planet is fixed. To feed the worlds population we may need to build 'up' as well as out, and this is what Aerofarms are doing.

Chris Nunn is the Head of sustainability at AMP capital, who have a Real Estate Portfolio of over 23 billion dollars, and he is also the chair of the Australian Passiv Haus Association. It seems like a long journey to becoming carbon neutral, but with solid leadership from investment firms, there is good reason to be optimistic.

Kevin Kelly is the founder of Wired magazine and author of the book 'The Inevitable - Understanding the 12 technological forces that will shape our future. The buildings industry has been stagnant for many decades and ripe for disruption. Understanding the technological forces will better prepare yourself for some of the changes that are on the horizon.

Michael Rowe is a director at Ethos Urban who are a leading consultancy in urban planning.

Samir Sinha is the founder of RobonomicsAI. Today there are new emerging technologies that are undoubtedly going to have a big impact on the buildings industry. Drones, AI, VR/AR, cryptocurrencies are still in their infancies but are capable of causing major disruptions to the status quo.

John Provis is a Professor of Materials Science and Engineering and Head of the Engineering Graduate School at the University of Sheffield. Concrete to many people is a boring subject - but John is clearly passionate about the material, and determined to find ways to lower it's embodied emissions.

There have recently been a lot of changes in how we consume our energy - technologies such as solar and wind are well known and are a great alternative to fossil fuels. However, new sources of energy are appearing on the horizon. In this episode I was amazed about the research Stanford engineers are conducting about the next wave of disruptive energy technology

Daniel Vogelnest is the founder of Ninox Robotics, who are leaders in drone and robotics technology. This is technology that 10 years ago - I would have thought is science fiction. You don't just need to listen this to understand the pace of improvement - not long ago the drones used by recreational uses were huge and expensive, years later they fit in a small back and are affordable to everyone. Ninox have some of the top technology and use it for commercial use.

Graham has one of the most diverse backgrounds I have ever come across. He studied mechanical engineering in Capetown, completed a post grad in advanced engineering analysis (FEM and Structural Analysis). He has been exposed to medical, energy mining, water, advanced materials and is now in politics!
