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! 

Amphiro test

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?

01

Guests saved 17% of water during their showers

We measured the effectiveness of a technological innovation (Amphiro) on hotel guest water-saving behavior. Our findings? A -17% (-3760L) reduction in water use, -215 kWh energy reduction and 60 kg less of CO₂e emitted.

02

Hotels using this device have a low payback period: 37 months

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 annual savings of €18,49 per room with a payback time of 37 months.

03

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 hotel guests. In fact, we noticed increased guest awareness & long term behavior change; water use was reduced by -10%, even after the device was removed!
