A Procedure to Define the Best Design Intervention Strategy on a Product for a Sustainable Behavior of the User

This paper presents a procedure that can be used to determine what kind of design intervention strategies can be implemented by designers for the improvement of the global environmental performance during the use phase of a product, regarding consumers’ behaviors.Four design intervention strategies have to be tested on espresso coffee machine: written information, eco-feedback, objective to reach and persuasive technology. Energy and water consumption during use phase of 36 regular espresso coffee machine users will be measured during the experimentation. At this stage, a first design strategy has been tested and environmental benefits have been highlighted thanks to LCA analyzes. Users’ variables such as environmental knowledge, attitude, habits, are also measured and a statistical analysis will be conducted for the validation of the model of relationship proposed.
