Sometimes solutions to modern challenges come from something as old as dirt – literally. The innovative, heat-regulating Austria Pavilion is constructed entirely from humankind’s oldest building material: loam, a soil of sand and clay. The dozens of cones that make up the pavilion use thermodynamics to pull in cool air from below and push warm air out the top, providing a natural climate-control mechanism. Their elegant blend of simplicity and ingenuity makes the pavilion both a calming oasis and a perfect place to explore innovations such as the heartbeat installation, which transforms your heart pattern into a dynamic digital projection.
