Abstract

This case study presents the design and evaluation of an end-user energy consumption display for an energy+ house. The goal of our application is to give an easy overview over the power balance and to provide the user with the necessary information to understand specific consumption patterns. We defined the unit of Counter Entropy points and used it to create several visualizations showing the consumption of appliances, climate control, and lighting. Our evaluation showed that users easily understand where the currently consumed power is sourced and which factors influence the overall power consumption.
