AquaLuce is an eco-friendly design solution which aims to build environmental awareness and encourage water saving. The product takes a completely new, innovative and exciting approach for sustainability and responsible consumption of natural resources. AcquaLuce calculates the amount of the water flows from the tap per handwash, with its flow calculator located under the sink flange, and transmits this amount to LED card by converting data to an equivalent color value, so that the LEDs change color from green to red according to the water consumed. AcquaLuce expresses water consumption visually that draws attention to sustainability and environmental awareness, and also puts forward a fun and meaningful solution.
