Exploring Persuasion in the Home: Results of a Long-Term Study on Energy Consumption Behavior

This paper presents a seven-months field study on a persuasive ambient display in private households. The FORE-Watch aims at adjusting the consumption behavior of energy users in 24 multi-person households and persuading them to change their timing of consumption activities; half of them were shown a forecast of the occupancy rate of the local energy grid (i.e., grid status), and the other half were shown how much energy will be delivered by green sources such as windmills (i.e., green energy). Our qualitative and quantitative survey and the energy consumption data revealed that the grid status group showed a more constant behavior than the green energy, indicating that the more dynamic forecast presentation did not lead to the same type of behavior change as the static forecast presentation. Overall, the FORE-Watch aroused awareness, attention and interest through permanent presence, clear and simple information, and changed the energy consumption behavior of our participants.
