Renaud Noret is project director within the architectural firm Valode et Pistre. “No architectural project is done without thinking about the issues of global warming” “The objective is to respond to the effects of heat waves, but also to reduce the energy consumption of the building,” he says.

Noret details the new materials and techniques used for new buildings in Paris and around the world. He says: “Some buildings are now designed in rammed earth, using raw earth bricks which have excellent insulation qualities”
