Abstract: This paper explores the effect of different forms of real-time feedback with upper limit goals on water consumption using data from two different devices. One device provides threshold based feedback, indicating when specific thresholds are reached while the other provides granular feedback through a meter which displays the consumption level at 0.1 litres intervals. While current data indicates both devices result in similar reductions in consumption, the threshold based device shows an aggregation of showers ending at the start of the second last threshold before the goal at 20 litres. The aggregation happens right after a noticeable change occurs on the granular device’s display when the 15 litres goal is surpassed. This thus indicates that a well-designed threshold based system providing less information may achieve better results when the goals are similar in resource conservation due to consumers being rationally inattentive.
