Inhabitants use energy to perform various activities of daily life in the private sphere i.e. the household scope. The activities they undertake are stochastic in nature and difficult to predict. Moreover there is a significant difference between real and theoretical uses of eco-designed products. It is therefore necessary to address the issue of measuring the real energy consumption of the inhabitants in order to identify their behaviour and decrease their environmental impact. In this paper we present an experimental study focusing on kitchen perimeter and cooking activity with two objectives: (1) ordering 20 advices to send to people by considering the perceived difficulty of practicing them and (2) identification of practice difficulties of eco-gestures by experience feedback. The aims are to get design inputs by increasing the difficulty of the activity and to identify needs related to a "weak" product design and consequently a user need to (re)design products for sustainable outcomes. Despite a low sample of 9 subjects, we get significant results allowing us to define a re-usable advices order and identify two real design needs from user feedbacks validating our approach.
