Effective visualizations of energy consumption in a feedback system - A conjoint measurement study

Abstract

Sustainable use of energy is one of the guiding principles of today’s society. But there is a lack of comprehensive analysis solutions for the energy consumption of private households to provide real insights. In order to provide useful information, feedback systems may be the answer. Numerous studies about feedback systems have been conducted so far and each individual component of such a system has been tested. The combination of these components leads to a dashboard for decision support of private households. Within this study the individual components were combined in several configurations and implemented as a prototype dashboard. A Conjoint measurement is used for evaluation and observation of user preferences collected in over 1,000 questionnaires. The result, an evaluated dashboard, combines several effective feedback elements based on user preferences and helps to save energy based on decision support and transparency.
