Label Office Labelling is the order of the day. Formally we know about energy labels and safety labels, but in our daily lives, we put labels on each other every day. Labelling and being labelled costs us more energy that we would like. In the Label Office, we play with the phenomenon “labelling” and the term “energy” in a humorous way in order be aware of what labels do with your energy level.
