KNX: 10 strong points (2)
One common design and commissioning tool• ETS™ Engineering Tool Software• Easy Mode mechanisms however allow linking without ETS for simple functions
and smaller scale installations Common Training
• Network of more than 250 independent KNX training centers in 49 countries worldwide
Product Certification• Products with KNX Trademark have been positively tested by third parties
Internationally standardized• CENELEC EN 50090 – CEN 13321 - ISO/IEC 14543-3 – GB/T 20965
Large service network of qualified contractors/designers/integrators• More than 37500 KNX partners in 121 countries worldwide

The KNX Standard – recent evolutions
Extending KNX’ USPs also to KNX RF• KNX RF Multi Channel Extension
I. Making it less susceptible to interference in the used frequency band• KNX RF+ Extension
I. Integrating KNX RF devices more easily with ETS into existing installations
• KNX Flexible Easy Mode channels
I. Make this configuration mode also the preferred choice for smaller scale (starter) installations and mobile devices
Securing KNX Frames• Necessary system extension for smart metering/smart
grid realizations• Encryption and Authentication possible for all KNX
media• Including specification for configuration of secure devices
(with ETS)

ETS – recent evolutions
The ETS App Concept• Presented at light+building 2012• Launched in May 2012 with ETS 4.1 version• Reasons:
I. Do not confuse newcomers with unnecessary (complicated) functionality
II. Not all functionality desired by ETS users can be realized on the association budget
III. Allow specific design tools for KNX installations for different markets, but keep ETS as only download engine
Internationalize use of ETS: 17 supported languages! Future ETS
• ETS 5 – scheduled launch light+building 2014I. support all KNX media, including KNX RF
II. Do away with MS SQL database for storing project data

Lowering barriers for KNX newbies (1)
KNX eCampus• Getting Started with KNX and ETS before going to 5 day course• Free of charge Web based Training Scheme to acquaint oneself with
- KNX Technology (Topology, Communication Media, …)- Setup of ETS- Working with ETS (creating new project, establishing links, downloading, …)
• For each chapter: exercise and test• At end: eCampus
certificate and ETS Lite Version
Available in 10 languages > 1000/monthly registered
eCampus users

ETS App ‘Online Catalogue’• This was then:
- ETS End User version is not shipped with databases of available KNX products
- ETS user can not start work immediately must find the ETS databases via the web sites of the different KNX solutionproviders
• Now also- KNX Manufacturers can upload product databases for their available
products on KNX server- Differentiation of product databases for different markets/languages
possible- Installed App can retrieve product databases directly from the KNX server
• Price- Totally free of charge for KNX manufacturers and registered ETS users

Scientific studies (HS Bremen, TU Trento)• Up to 50% energy reduction compared to conventional installation techniques in a
well insulated building Calculate effect of KNX on energy efficiency by tools of KNX members KNX controlled HVAC applications
• KNX Room Controllers• KNX Schedulers• Presence Detectors• Window Contacts• C02 sensors
KNX Controlled Lighting• Daylight intensity sensors• Presence Sensors

KNX City: vision = reality
Buildings
Energy efficient buildings with KNX are the
basis for sustainable cities
Mobility
The eCar is an integral part of the intelligent
building based on KNX
Infrastructure
Individual homes and buildings are
interconnected through KNX
Energy production
Renewables are an integral part of the
intelligent building based on KNX
