The EEI Market Transformation Research Team worked with UC Davis Housing and Facilities Management to conduct an experiment aimed at reducing energy and water use in on-campus housing. The Team deployed Hydrao smart showerheads that monitor water use and provide feedback to users. The showerheads have built-in colored lights, which are programmed to illuminate during the shower and change colors based on the volume of water that has passed through the nozzle. The showerheads were installed in the bathrooms of two residence halls, serving 400 students. Average shower length decreased by 1.5 minutes and 92% of users who responded to a survey at the end of the study reported using the lights to time their showers.
