Energy Efficiency Enabled by Systematic Integration of End Con- Sumers by Using an Innovative Interface

The present study draws attention to increasing energy efficiency in private households enabled by systematic integration of end consumers by using an innovative interface. The object of investigation is referred to technical and social requirements towards a consumer interface to present energy consumption. As the success of interfaces is a question of consumer-friendly design it was questioned what are the technical requirements, the consumers’ expectations and to what extend do they meet. Therefore N=48 students took part in a user experience study. They were asked to complete an online questionnaire including different visualizations for energy consumption on a mobile interface. The results showed that different forms of visualizing energy consumption have different effects on the evaluation, user experience and in the end on the transparency of energy consumption. The present findings suggest that further investigation on specific design aspects of energy consumption is necessary.
