Abstract:This research addresses the issue of excessive water consumption in toilet flushing, specifically in dual-flush toilets. This study was commissioned by the University of Twente's campus facility management (CFM). The study uses nudging techniques to influence the flushing behavior of users, focusing solely on norm-setting nudging techniques. It aims to answer the question: to what extent can nudging influence the toilet flushing behavior of the Zilverling community. The Button Nudger including a button press registration setup was created to convey the nudging message and to measure which flushing button was used. A zero measurement and intervention measurement were conducted to find out whether the implementation of The Button Nudger had an effect on flushing behaviour. It was concluded that it is plausible that norm setting nudging can influence toilet flushing behavior within a certain group of the Zilverling community. A user evaluation revealed that approximately 20% of participants felt influenced to alter their flushing behaviour, but also highlighted the need for improvements in the perceived privacy, intrusiveness, and design of The Button Nudger. While there is uncertainty on the lasting effects on water conservation, the study suggests that norm-setting nudging is promising when implemented to stimulate correct toilet flushing behaviour.
