Norms are, by nature, voluntary application dispositions; anyhow, complying with
norms constitutes the best guarantee in the choice of a product for designers,
installers and end users. In fact, norms are “state-of-the-art” developments in their
technology sector and precisely define quality, performance and safe conditions of
use for a product. Beyond safety norms regarding all products, the systems for the
control of houses and buildings are more often requested to integrate energetic
efficiency models, consistently abiding to recent tendencies aiming at global
system-envelope system efficiency, more so than seek optimization of single parts.
KNX represents an open and interoperable system for the automation of houses and
buildings, normed at global level thanks to its conformity with international (ISO/
IEC 14543-3), European (CENELEC EN 50090, CEN EN 13321-1 e 13321-2), Chinese
(GB/Z 20965) and American (ANSI/ASHRAE 135) norms.

ISO/IEC 14543-3
Information technology - Home electronic system
(HES) architecture
In sight of the great interest towards KNX compatible products and the technology by them consolidated well beyond European
markets, the KNX Association took all necessary steps to obtain approval of its own KNX standards at international levels. At
the end of 2004, active CENELEC member countries proposed the European EN 50090 norm for ISO/IEC standardization. In
November 2006, the KNX protocol and all transmission media (TP, PL, RF and IP) became approved and published under the
international ISO/IEC 14543-3-x normative.
EN 50090
Home and Building Electronic Systems (HBES)
In December 2003, the KNX protocol and the two TP (twisted pair) and PL (power line) transmission media were approved by
the European national committees and ratified by the CENELEC Bureau Technique under the European EN 50090 norm. The
transmission medium KNX RF (radio frequency) was approved the month of may 2006.

Product and system requirements
Since KNX supplies more and more technical specifications used not only for the automation of electrical devices, but also
for HVAC (Heating, Ventilation and Air Conditioning) applications, the KNX Association submitted its specifications to CEN
for publishing a European normative for building control systems. CEN accepted the proposal and KNX specifications where
published by CEN as EN 13321-1 and EN 13321-2.

Control network HBES technology
specification - Home and building control
The great interest demonstrated by China for KNX products and technology was the main reason for the KNX Association
to have the international ISO/IEC 14543 norm translated into Chinese. The Chinese standardization committee SAC TC 124
introduced the KNX standard into China and adopted it under the GB/Z 20965 norm in July 2007.
ANSI/ASHRAE 135
BACnet - A Data Communication Protocol for
Building Automation and Control Networks
(ANSI Approved)
Even the interfacing of KNX with other automation systems is now internationally standardized: the norms US ANSI/ASHRAE
135 and ISO 16484-5 support mapping between KNX and BACnet.

The EN 50090 norm
The European EN 50090 norm “Home and Building Electronic Systems (HBES)” was
developed at CENELEC from the TC 205 Technical Committee, specifically established
in 1996 to write norms covering all relevant aspects of electronic systems dedicated
to the control of homes and buildings. Parts of the norm were progressively released
and published by the standard committee of several European countries giving birth
to the national norms about the electronic systems for homes and buildings.
Beyond the requirements for the development of HBES systems and components,
aimed at builders, the norm also defines the criteria for designing, installing and
testing an HBES system. The KNX standard is entirely compliant with the EN 50090
norm.
