Heating, cooling and dehumidifying air in buildings currently consumes one sixth of all the energy used in the world. With the "Cleanair" system Professor Matthew Johnson of the University of Copenhagen has created a device that cuts building energy use by up to 25%.
In a real-world test 40 different compounds were removed from a new office building at the University of Copenhagen within minutes of switching on the device.
Every second we pump air into our houses that is too hot, too cold or too moist. And then we spend billions of kilowatts treating that air; cooling it, heating it or dehumidifying it. If we could clean the air, we could recycle air that already has the perfect temperature
