Result of the study The utilisable literature sources clearly indicate significant potential for optimisation regarding reduction of the energy consumption by the use of modern electrical installation systems:
The average value of all the sources results in a saving potential in the range of:
Room heating control:
approx. 14 - 25 %
approx. 7 - 17 %
approx. 9 - 32 %
approx. 25 - 58 %
approx. 20 - 45 %
In total, this results in an average energy saving by general measures and optimisation of the control engineering in the order of approx. 11 to 31 %.
The corresponding maximum values of the different areas recorded in the literature in the study can be seen in the following diagram.
