• before 1997 : 3 major bus associations in Europe– Batibus Club International
• Promotion of Batibus solution• installation bus medium originally developed by Schneider Electric• especially successful in France• use especially in electrical material and HVAC appliances
– EIBA• Promotion of EIB solution• installation bus medium/protocol originally developed by Insta-Siemens-Merten• especially successful in German speaking countries• use especially in electrical material and HVAC appliances• Attempt to standardise EIB in the framework of CENELEC TC205 – only standardisation of HBES hardware requirements in EN 50090-2-2 succeeded
– EHSA• Promotion of European Home Systems• Bus medium/protocol emanating from a European project for automatic configuration of networked white (washing machine, …) and brown (video, …) goods

The road towards KNX: Convergence Process – history (2)
• ‘97 : Start of the convergence process - goals– Bundling activities of BCI, EIBA, EHSA in a new association
•A non-profit organisation with registered office in Belgium• Income : annual member contributions (staggered according to company size) – certification fees
•Members : – Manufacturers, Service Providers (e.g. telecom, …) and interested parties
(e.g. software houses, …), no licensees•organisational structure: General Assembly, Executive Board, Technical and Marketing Boards (with respective expert and working groups)

The road towards KNX: Convergence Process – history (3)
• ‘97 : Start of the convergence process - goals (ctd.)– Creation of a joint standard for a new bus system « KNX »– European Standardisation of the KNX standard by becoming co-
operation partner of CENELEC (European Committee for Electrotechnical Standardisation)
– Registration of a new trademark– Start of a Certification procedure
for KNX compatible devices
• 14 April 1999 : Founding of Konnex Association in Brussels with 9 founding members
• 20 March 2001 : first General Assembly

Konnex : current status association
• Konnex tasks around the KNX system:– Elaboration and extension of the KNX-Specifications– Technical Hotline-support– International Standardisation– Protection of the KNX (and legacy) Trademarks– Certification of KNX compatible products– Standardisation of Training documentation – Certification of
training Centres– Communication – Promotion – National Organisations– Partnerschip for Universities and Technical Institutes –
Organisation of the annual Scientific Conference

Konnex: current status association(s)• Non-commercial activities of Batibus, EIBA and EHSA by contract
delegated to Konnex : Konnex from April 2003 onwards responsible for:– Rest promotional activities for the legacy systems– Clarifications of the (frozen) legacy specifications (if still needed)– Support for the legacy systems (if still needed)– Certification procedure of the legacy systems EIB and EHS– Further granting of EIB Partnerships– all work in the legacy expert/working groups has in principle
been suspended• EIBA remains in existence however only for
– Specification, Marketing and sale of EIB/KNX tools (a.o. ETS)– Statutes have been changed to better reflect this reduction of activities
• Batibus transformed into Konnex France

Konnex: miscellaneous
• Size of the current association : – Over 90 members (also companies, which had not been a
member in the legacy associations) from such fields of application as:
• Lighting control• Shutter control• Heating, Ventilation, Airconditioning• Alarm/intrusion systems• Household appliances
– Membership for new companies now only possible in Konnex

• Referencing of EN 50090 in CEN– Will replace the ENV 13154-2 specifying the individual KNX legacy
systems• Referencing of EN 50090 in ISO/IEC SC25• Submission of additional standard parts for EN 50090 to
CENELEC BT– Radio Frequency specifications– KNX Interworking Model
• Submission of additional standard parts in CEN– KNX over IP specifications for integration into ENV 13321-2 as
successor to EIBnet IP specifications
Future scheduled standardisation work

Standards for intelligent buildings: summary• Added value of « intelligence » of buildings can only
be achieved by systems that– Are offered by a large variety of manufacturers,
preferably organised in manufacturer/standardisation associations
– Cover different application domains– Have low threshold for starting contractors and planners– Can be used for smallscale (residential) as well
commercial projects (offices, hotels, airports, …) – ensure multi-vendor and cross-discipline
interoperability– Have system and interworking requirements that are
verified through a solid certification procedure using third party test houses
– Conform to European standards as this increases user’s feeling of security/quality
