Environmental impact of non mobile electr(on)ic products is mostly due to energy consumption in use phase. Along with the growing concerns on energy supply, it explains the increasing interest on efficient management of energy during use of electr(on)ic equipment. This papers introduce a new indicator to follow the in use energy consumption from the earliest design stage to the beginning of the manufacturing stage. Energy in use is characterized by lifetime by power. Lifetime is defined as sequences of function and power as sequences of stable power consumptions of sub-assemblies. The use of the indicator is simulated in the redesign of a set top box.
