The aim of the project was to improve water efficiency at home through targeting behavioural change. The design was based on a set of criteria, which were: the product had to produce just-in-time prompts, quantify water saving, and conform to the user's use habits.
The design is called Lumo, a tap ware range that combines functional beauty and intuitive software to motivate mindful water usage and improve water efficiency at home.
The design was motivated by the need to provide immediate feedback on water usage. As the bathroom is typically used as a place for people to relax, it was important to ensure that the design was simple and that the feedback did not disrupt the user.
A simulation of the light feedback was then created to test its effectiveness. A set of 7 light sequences were used in the test. Respondents were asked to talk about how they felt about each iteration. Below are some comments made about the chosen concept.
“I like the simplicity. I want to race it.”
“Makes the most sense and the mapping is clear.”
“Looking at the light flow down is calming but
also tells me I’m running out of water to use.”
Lumo is a tap ware range that combines functional beauty and intuitive software to motivate mindful water usage and improve water efficiency at home. Tap ware has an active role to play in the way we use water. As the bathroom is a space we use every day, Lumo gives a better opportunity to foster behavioural change of water use in the modern household.
Lumo is responsive, producing clear, immediate feedback on water use in the form of light signals; ubiquitous through integrating smart technology and connectivity to other devices; and is self-powered for easy maintenance. It enables users to become more aware of and understand their water usage, offering a way for them to make lasting changes to their consumption habits.
We use an average of 85 litres of water in the bathroom every day on just the tap and the shower. With Lumo’s just-in-time prompts and effective water usage, users can save up to 60% of water use daily.
Target water use its based on recommended water usage and is calculated on a per-use basis, which includes 90 second breaks within each session of use. To tailor to individual needs better, users are also able to set their own targets through an app. Quotas will be presented to the user upon the provision of their household size, location, and number of fixtures. Usage is then tracked accordingly.
