*4.2. Determination of the Physical Characteristics of the Available Industrial Systems*

Once the available industrial systems and the relevant implementation objectives in the production facility have been defined, the way each system consumes energy needs to be understood. Hence, the system needs to be energy transparent. An initial understanding of the energy consumption of the industrial system is achieved through its physical characteristics. The physical characteristics from an energy transparency perspective are [14]:


For appropriately defined industrial systems, the physical characteristics can be easily inferred from surveying the technical specifications of the system's components. The physical characteristics provide an initial level of energy transparency and hence a very superficial overview of the available EFMs and, up to this point, theoretical EFP.
