Concrete - The Most Consumed Material on Earth

For thousands of years, people living in parts of the world used to high temperatures have deployed traditional passive cooling techniques in the way they design their buildings. But "modern" styles of architecture using concrete and glass often usurped local building techniques better suited to hotter climates. In this episode, we explore why that happened, and how some architects are championing traditional techniques to help keep buildings cool.

Featuring Anthony Ogbuokiri, senior lecturer in architectural design at Nottingham Trent University in the UK, Vyta Pivo, assistant professor of architecture at the University of Michigan in the US and Susan Abed Hassan, professor of architectural engineering at Al-Nahrain University in Baghdad, Iraq.
