The house of energy productivity offers general guidelines
for the deduction of specific measures to improve energy
productivity based on the identified energy waste. Every
measure must be positioned into a portfolio to identify its
impact on the two dimensions of the energetic approach and
the consideration level (fig. 5). The energetic approach
describes whether the measure has an impact on power, on
time, or on both. With the consideration level the
differentiation between an impact on one single process step
or on several process steps or the whole process chain is
made. Further information about the second step of the
methodology is given in [14].
