We use individual approach, that is based on a customer’s segmentation. We consider that everyone has its own motivation factors, such having fun, learning or collecting reward points. Firstly, our objective is to challenge people to achieve their objectives by following these specific motivation factors. Secondly, the efficiency indicators value the efforts of individual client. Finally, this green nudge approach motivates energy consumers in his energy efficiency efforts and strengthens its loyalty to his energy supplier. This is based on win-win benefits, proposed to both energy consumer and energy utility. Our architecture is capable to determine important socio-economic factors, that are important for consumption profiles definition and individual motivation approach.
