2.2. Energy oriented value stream mapping and house of
energy productivity
The idea of the first step of the methodology is to choose a
certain process chain and create transparency about
production and energy data. From a state of the art research it
is obvious, that the value stream mapping and its
energetic derivatives are appropriate to support this
idea. The existing value stream methods were evaluated and
extended by a detailed analysis of the electric power for all
existing operational states in production. During the
traditional value stream analysis the user of the method is free
to collect all the production data which he or she attaches
importance to. In the energy oriented value stream mapping of the methodology, the user gets a list of production data, which
is due to collect. This list contains all actuating, endogenous
and exogenous figures from the LPS impact network. As a
result, the energy oriented value stream mapping provides all
values needed for the impact network and all the energy data.
Its transparency gives an overview of the existing energy
waste potential as well.
