Integrated building energy management for the energy system of the future with electricity and gas

FZI House of Living Labs
In FZI House of Living Labs, computer science researchers work together with developers from the E.G.O.-Group to generically integrate conventional and hybrid household appliances into energy management systems. Thanks to intelligent interfaces, the devices are able, for example, to automatically respond to the decentralised energy production of various energy sources in the building and thus form the basis for additional value-added services that are related to safety and comfort.

FZI House of Living Labs offers a modern development and evaluation platform for the future components of an integrated energy management system where both electrical and thermal energy flows are taken into consideration. In the process, the intelligent control of decentralised producers, storage units and (hybrid) consumers for developing load flexibility as well as the coupling of energy management features with additional value-added services serve as important goals.

The core of the building energy management system is the Organic Smart Home software framework. Using a hardware abstraction layer and the appropriate drivers, it enables the generic integration of the various facilities and systems, regardless of the manufacturer. The software also enables external signals.

The cooperation project is focused on generically integrating household appliances by using E.G.O. communication modules that are installed directly into the existing appliances. In addition to classical protocols for building automation and adequate wireless standards, the EEBus is used for a largely standardised exchange of the applied information.

Under the project, energy efficiency focuses both on the application of electrical energy as regards variable electricity prices, performance limits, self-sufficiency and the maximum use of self-produced electricity and on the use of other energy sources such as natural gas or district heating.

With the development of hybrid household appliances, gas and electricity can be used in a parallel and coordinated manner. It is important that the implementation process be carried out with the help of electronic E.G.O. control elements for heating systems that can cover both energy sources. The specific characteristics of gas or electrical appliances are compensated in the device by corresponding E.G.O. components in order to create a degree of similarity for the user. This makes it easier to switch between different energy sources and allows the advantages of each energy source to be used efficiently. Different types of heating and output combinations facilitate adjusting the appliances in the building energy management system for an optimal output. Besides the various production systems in FZI House of Living Labs, hybrid household appliances offer excellent conditions for this purpose. Interdependencies between the different energy sources can therefore be considered while optimising energy flows in a smart building. To achieve this, it is essential that information and communication technologies which span multiple manufacturers and are as standardised as possible be developed. This should apply to the gas industry in particular.
