Inspired by elephant ears, new wall design could help buildings stay cool and cut energy use

Drawing inspiration from the venous ears of jackrabbits and elephants, Drexel University researchers have come up with a new approach to passive heating and cooling that could one day make buildings more energy efficient. Their concept, recently published in the Journal of Building Engineering, embeds a vascular network within cement-based building materials that, when filled with paraffin-based material, can help passively regulate the surface temperature of walls, floors and ceilings.
