Shorter showers living lab

How can we motivate guests who don't pay the water and energy bill to consume less hot water?

Together with Innovation Lighthouse, Wageningen University & Research and valuable contributions from other partners, The Student Hotel hosted a living lab to find an answer to the question how to influence behaviour if financial incentives are not an option. The outcome: all you need is a little nudge!

How can we motivate people who don’t pay water and energy bills to consume less without using financial incentives?

What did this project find?


Guests saved 17% of water during their showers

We measured the effectiveness of a technological innovation (Amphiro) on guest water-saving behavior. Our findings? A 17% reduction in water use and 60 kg less CO₂e emitted per room in one year as a result of the energy saved on heating water.


Hotels using this device have a low payback period

We produced new practical insights for organizations who want to stimulate savings in cases where users don’t pay for utility bills. The findings above translated into a payback period of around 3 years in the Netherlands. This could be less in other countries with higher water & energy prices!


Giving real-time feedback really works to reduce water use

We show that interventions providing real-time feedback help to significantly reduce costs, carbon emissions and contribute to the education and behavior of tenants. In fact, we noticed increased awareness & long term behavior change; water use was reduced by -10% for longer term guests, even after the device was removed!
