October 12 KNX: The worldwide STANDARD for Home & Building Control
European Standardization (1)
• CENELEC (1)
• European Committee for Electro-technical Standardization
• Responsible committee = Technical Committee (TC) 205
• Scope: Home and Building Electronic Systems
• Standard series for home and building control = EN 50090
• KNX Association • Cooperating Partner to CENELEC = important player in the field of
home and building control
• Possibility to submit standardization proposals without need for New Work Item proposal by national committees
• Before 2003: EN 50090-2-2 • Only existing part of EN 50090 series documenting hardware
requirements
• EMC, Electrical Safety, Environmental conditions
• System independent

European Standardization (2)
• CENELEC (2)
• Since 2003: • approval of European TC 205 national mirror committees of
• KNX media (TP, PL, RF)
• KNX protocol (LL, NL, TL, A(I)L)
• Management procedures
• KNX Interworking model and KNX standardized data types
• All part of the EN 50090 series
• Since 2010: • Out-phasing of EN 50090-2-2
• Replacing by new standard series EN 50491
• EN 50090 becomes fully KNX – EN 50491 collects hardware requirements for any HBES solution, even systems that are not EN 50090 compliant

European Standardization (3)
• CEN
• European Committee for Standardization
• Responsible committee = Technical Committee (TC) 247
• Scope: Building Automation Control Systems
• Currently standardised systems • LON: EN 14908 series
• BACnet: ISO 16484 series (see worldwide ISO standardization)
• KNX
• Extend of KNX standardization • EN 13321-1
• EN 50090 series referenced as standard also for BACS
• EN 13321-2
• KNXnet/IP tunnelling and routing protocol
• Transmission of KNX frame encapsulated in IP frame
• Part in turn referenced in the EN 50090 series
• EN15232
• System independent standard documenting impact of use of BACS on energy efficiency of buildings
• As KNX = BACS standardized system, indirectly KNX = solution to fulfil EN 15232 standard

Standardisatie
EN50491
Alleen hardware requirements, geen protocol
Geen storingen, geen veiligheidsproblemen
EN15232
EN50090 is een protocolserie die toelaat te
voldoen aan EN15232: energiesparen
<Joost Demarest>
< KNX Association cvbar>
Page No. 13
October 12 KNX: The worldwide STANDARD for Home & Building Control
Standardisatie
EN50090: één protocol Eenvoudiger, goedkopere en verdere integratie van
toepassingen: verdere automatisatie en besparing,
verdere comfortverhoging
Aanvangsfase
Vermijd duurderde, langere integratie van incompatibele
systemen.
Onderhoud, evolutie, uitbreiding
Stabiliteit: betere garantie van flexibilitiet naar de toekomst
Interworking: uitzonderlijk hoog niveau van
samenwerking produkten van verschillende fabrikanten
KNX: één enkel tool
