In preliminary works, an impact network has been created,
which describes the existing impact relations in a generic
process step, following the principles of LPS. In the first step
of the methodology, the energy oriented value stream analysis
creates transparency over a considered process chain and
identifies energy waste potentials. Following, the house of
energy productivity helps to derive energy productivity
measures. The implementation of these measures is simulated
with a generic system dynamics model in order to identify
impacts on LPS target figures including energy intensity.
Finally, this important information is used in an extended
economic efficiency calculation, which supports the user of
the methodology with the decision, whether the measure
should be implemented or not
