The Static! project, developed by the Interactive Institute, aimed to
investigate how interaction design could increase users awareness of how
energy is used in order to stimulate changes in user behaviour.
Several
products were prototyped as part of the Static! project, one of which
was the Disappearing Pattern-Tiles.
The Disappearing Pattern-Tiles act as a
subtle yet effective reminder of energy and water use. Decorated with
heat-sensitive thermo-chromic ink, these highly patterned tiles
communicate heat loss generated during prolonged showering visually by
fading over time, the longer one showers the less decoration on the
tiles.
You can find further examples of products designed to raise
awareness of energy use on the Static! website
