Due to the increasing use of energy-efficient buildings and modern technologies used in them, primary energy demand steadily shifts from the direct use of fossil primary energy sources for several processes such as heating, to the indirect use by electrical power consumption(for example, compression heat pumps, ventilation). The result is higher base loads and in some cases increased peak loads, something that can also be reflected in the increased energy load of the buildings. This increase signals also the increase of the so-called “Energy-Plus Buildings”.
All the above have as a consequence the steady increase of decentralized energy production. The decentralized energy production is subject to availability and due to the complexity of the distribution and supply networks is only partially predictable. Therefore, new concepts in the operation management and planning of the building management technology must be found in order to reduce the maximum supply and ensure a stable and high-quality power supply.
This project addresses the prime question regarding to what extend the load profiles can be smoothed (peak shaving) and controlled by means of new control strategies in the thermal and thus the electrical operation of functional buildings. An assessment of the possible energy saving and the associated CO2 reduction is carried out by changing the load profile. The building or a building group is upgraded to an active consumer in the electrical network.
