A Living Lab

to Encourage Short Showers

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!
