One of the challenging environmental issues faced by the electr(on)ic industry is the development of energy efficient products during their use. Indeed, regulations, standards, and consumers have always growing expectations on this aspect. Nevertheless, tools to support design for energy efficiency in use are scarce and do not always give an appropriate answer to the challenge. This paper presents a new methodology based on the calculation of an indicator that enables a design team to drive

The indicator combines the power of components with time spent by these components to do their jobs, in order to lead to energy consumption estimation. When used for design purposes, the method can provide the team with a relevant analysis of the energetic performances of the product, including modes, jobs and scenarios variations. This analysis can lead to product's hot spots and eventually to design strategies. A case study on an existing electr(on)ic equipment is proposed for illustration purposes.
