The paper proposes an alternative approach to well-known feedback solutions, such as visual displays or warning sound messages, to make users perceptually aware of the energy consumption occurring when using a product. The approach is grounded on the use of multisensory feedback interfaces that are designed to make the user experience the consumption process directly during the interaction with the product. Such multisensory feedback should be intended as indications, rather then alarms, so as to naturally guide users towards a more sustainable behaviour. The daily task of opening the fridge door has been used as case study. All the steps followed to ideate and test the effectiveness of the designed multisensory interfaces are discussed. The results demonstrate how even simple stimuli, such as a gradual colour change of the fridge cavity from a cold to a warm one, may be able to reduce the time users keep the fridge door open.
