In this publication, A. Bejan draws attention to the emerging literature and physics principle (constructal law) that provide the scientific foundation for sustainability. He shows that the sustainability need is about flow: the flow of energy and the flow of water through the inhabited space.
All the flows needed for human life such as transportation, heating, or cooling, water are driven by the purposeful consumption of fuels, and this is why the wealth of a country (the GDP) is directly proportional to the annual consumption of fuel in that country.
Sustainability comes from greater freedom in changing the organization – the flow architecture – that sustains life. Greater freedom to change the design (from water and power to laws and government) leads to greater flow, wealth, life and staying power, i.e. sustainability
