EEBus

EEBus is a new data communication standard forming the interface between in-house communication and the energy supplier. The standard is currently under development. It connects the IP world of the smart grid and smart phone to automation and communication networks in the home and building area. For this purpose, EEBus supplies an application-neutral standardized interface.

EEBus is initially bridging the following three standards:

• ISO EN 16484-5 (Data Communication Protocol – BACnet)
• IEC 14543-3 (Home and Building Electronic Systems – KNX)
• EN 14908-1 (Control Network Protocol – LON)

Devices and systems utilizing the EEBus standard have to comply with the international and national regulations imposed by implemented communication protocols, such as the selection of frequencies or EMI / EMC limitations. Grid connected system elements must prove compliance to the applicable grid code(s).

The EEBus services by TÜV Rheinland can support you with

• Faster time-to-market through interoperable system elements.
• Competitively positioning your products with our independent third party test mark.
• Extensive one-stop shop services, especially for certain use cases identified by industry specialists.

Our experts are happy to answer your questions and provide you additional information on EEBus. Contact us!

We are currently involved in developing specifications for EEBus-compliant technology. Further details about our services will be provided upon the International Electrotechnical Commission (IEC) release of the EEBus standard.

Our future services will consist of the following steps:

• Compliance testing of devices against the technical standard (based on test standard)
• Interoperability testing
• Co-existence testing (with other, similar systems)
• Performance testing

EEBus is suitable for various applications and functions in both home and building automation and control. These areas include:

1. Energy management

• Load shift
• Demand response
• Source combination optimization
• Storage management
• Heating / cooling management

2. Room climate management

3. Position lighting management

4. Condition-triggered functionality

• Heating-off, if windows are open (indicated by position sensors)
• Light on/off based on room occupation (presence sensor based)
• Combination of natural and LED light for selected luminescence
• Price-signal driven utilization of feasible loads
• Windowshade closure in case of hailstorm

5. Use case implementation

• Optimized light / humidity supply to room flora
• Occupant-requested room climate establishment
• Ambient-assisted living functions
• Energy-optimization planning
• Comfort vs. cost optimization

If you have any questions concerning EEBus, please do not hesitate in contacting us. We are available around the clock, seven days a week.

EEBus is the result of the “Smart Watts” subproject, part of the German promotional program E-Energy.

Hence, the EEBus Initiative e.V. was formed to provide decision-makers, innovators and others a platform upon which to bundle their interests and competences in order to create sustainable solution spaces. The initiative is based on a networking concept according to the standards.

The EEBus Initiative e.V. is a registered, non-profit association actively representing the interest of the association and its members in activities such as standardization and research projects in order to lay the foundation for a comprehensive brand, crafts and market connectivity. The goal of the initiative is the continuous development of EEBus as a standardized and consensus-oriented smart grid and smart home networking concept.
