We’re using more energy and in the UK a lot of this goes into heating or cooling our homes but can we use natural processes to make this happen? Laura, Rwayda and Antonia discuss how using traditional clay in the Caribbean keeps houses cool while a smart architect in India has used fundamental physics to achieve the same feat.

Fact check: Building houses out of clay in the Caribbean The science behind why clay is cooler than concrete Using thermodynamics and natural wind direction to keep a house in India cool What makes a passive house
