Colour changing shower head lights nudge Disney Hotel guests to use less water, whilst showing real-time usage.
What unsustainable behavior needs to change:
Water waste in hotels resulting from showering is a significant problem, especially when guests do not concern themselves with the extra costs. On average, hotel guests likely shower for 8-10 minutes, a significantly increased use of water as compared to a more economical 5-minute shower when at home.
This behaviour is simply bad for the environment and contributes to unnecessary water depletion. And moreover, because hotels consume thousands of litres of water on a daily basis to accommodate this increased demand, hotel operational costs are also inflated.
The Green Nudge:
As part of its ongoing mission to reduce water usage, Disneyland Paris is testing special water-saving shower heads at Disney Sequoia Lodge. These illuminated showers start with a soothing blue for the first 10 litres; switch to an encouraging green up to 20 litres; then shift to a reflective purple when the guest uses up to 30 litres; and finally signal with a bold red, when guest usage exceeds 30 litres. This clever use of universally recognized colours not only promotes shorter showers, but also merges significant behavioural change with enjoyment.
The result: The „Hydrao shower heads“ have successfully reduced water use in showers by 22% at the testing lodge. Pending their continued effectiveness, the resort plans to expand the installation of these efficient shower heads and water-saving toilets in all of Disneyland-Paris hotel rooms.
To boost conservation efforts even further, Disney-Paris ought to consider enhancing the water-light system by activating the red light earlier.
