BED - Balancing Energy Demand with Buildings
Das Projekt BED zielt darauf ab, neue Konzepte in der Betriebsführung und Einsatzplanung der Gebäudeleittechnik von Nichtwohngebäuden zu finden, um maximale Bezugsleistungen zu reduzieren und eine hochwertige Stromversorgung zu gewährleisten.

Summary
Starting point / motivation
The increasingly spread construction of innovative buildings and the according technologies results in a shift from the use of fossil energy resources to the indirect use of electrical equipment such as compression heat pumps, ventilation etc. to meet the primary energy needs. This leads to higher base loads and partially to pronounced peak loads, which alter the load profiles of the buildings. Furthermore, there is the trend, that the number of so-called ‘Energy-Plus-Buildings' is increasing1. This results in a decentralization of the energy production, which is thereby dependent on the energy supply, and in a poorer predictability due to the complexity of the distribution and supply networks. Accompanying to this development it is therefore necessary to develop new concepts for the operation and application of the building control to reduce the maximal energy consumption to ensure a stable and high-quality power supply.
Contents and goals
This project addresses the issue of the possible extent of smoothing of load profiles (Peak Shaving) of functional buildings by new automation techniques for the thermal and the electrical operation and thus offering room for a more efficient automation. An assessment of the possible saving of energy and the subsequent CO2-reduction by the improved load profile will be carried out.
Methods of treatment
- Data analysis of the current state in terms of thermal- and electrical performance and user behaviour in ENERGYbase
- Modelling, validation and thermal simulation
- Identification and validation of balance energy potential due to scenario variation for an individual building as well as a building network
Expected results / conclusions
The result of this project will be an intelligent automation strategy which can be applied in currently used automation techniques and which serves as interface between an optimal usage of storage techniques, the optimal integration of buildings in regenerative energy systems and the structures of network operators and power suppliers.
