When we conduct our experiments in Cobham, we pay a lot of attention at the quality of the feedback we provide to users in laboratories. This is extremely important for the successfulness of the proposed tools aimed to aid saving energy in household electricity consumption. If we look at the literature, we can find several recommendations to implement these feedbacks. For instance, this article by Corinna Fischer provides a set of interesting recommendations. Above all, the most successfull feedback combines the following features:
it is given frequently and over a long time, provides an appliance-specific breakdown, is presented in a clear and appealing way, and uses computerized and interactive tools.
