KNX and BACnet

Two ComplementaryOpen Standards

Standardized Mapping KNX to BACnet

BACnet and the KNX Association have agreed upon a standardizedmapping for the two open standards. The Mapping facilitates thepreferred implementation of both communication standards inbuildings: BACnet for the building automation and KNX for thebuilding management systems. The mapping is documented inannex H.5 of the BACnet standard.

The KNX-protocol has been standardised as the Home and BuildingElectronic Systems (EN 50090) and is therefore the basis for efficientbuilding management. The KNX standard fulfils the most importantpreconditions: unified commissioning tool and transparent communicationbetween local actuators and sensors. The main advantages of the KNXprotocol are threefold: full Interoperability, product quality and highestfunctionality for standardised and complex applications.

BACnet as global standard for building automation has proven itsstrengths for the automation of primary supply systems. The same goesfor the integration of systems of different application domains as regardstheir functional interaction and comfortable, common visualisation.BACnet can also ensure data management as a means to optimiseenergy, resources and operational costs of a building.The combination of KNX with BACNet standard is not entirely new.To name but a few reference projects in which this combination wasalready successfully used: the Neues Kranzler Eck in Berlin, the StihlAG factories in Waiblingen (Germany) and the Saint Olavs Universityhospitals in Trondheim, Norway.

The standardized mapping between BACnet and KNX significantlyfacilitates the development of products to ensure a seamlessinfrastructure, from room automation up to the overall buildingmanagement system. The basis for the relationship between KNX andBACnet lies in the comparability of KNX functional blocks and BACnetobject types, while KNX data points correlate one-to-one to BACnetproperties. The KNX functional blocks and the BACnet object types haveidentical semantics as regards data structure: in this way, properties can

be easily exchanged.The mapping principles are documented in annex H.5 of theANSI/ASHRAE standard 135 entitled Using BACnet with KNX. Thisdocument is identical to the world standard DIN EN ISO 16484-5.

Due to the standardized mapping it is possible to develop standardizedlow-cost interfaces able to connect building systems engineering andbuilding automation and their individual strengths. This constitutes anirresistible offer for the realisation of an overall building managementsystem. This is the best prerequisite to continue to also in the future
