What Is the KNX Smart Building Standard?

KNX is a worldwide standard for home and building automation, developed and maintained by the KNX Association. It allows products from different manufacturers to work together seamlessly on a single installation — a concept known as interworking.

Unlike proprietary systems, KNX is open and manufacturer-independent. This means:

  • Any certified KNX device can communicate with any other certified KNX device
  • You are not locked into a single vendor
  • The system can be expanded, modified, or upgraded at any time

Today, KNX is recognized as a standard by major international bodies and is used in projects ranging from small apartments to large commercial towers.

A Brief History: From EIB to KNX

The KNX Association was founded in 1990 in Brussels, Belgium, under the name EIB Association, with the goal of promoting smart homes and buildings and introducing the European Installation Bus (EIB) system.

In 1999, a major merger took place with two other European associations — BCI (Batibus) and the European Home Systems Association (EHS). This merger led to the creation of a unified standard and the renaming of the organization as the KNX Association.

International Activities of the KNX Association

To achieve its goals, the KNX Association carries out extensive activities at the international level. These activities ensure that the standard remains open, reliable, and globally recognized.

A) Technical Development and Standard Promotion

The association continuously works with its members (manufacturing companies) to develop and improve the KNX standard and to promote it worldwide.

B) ETS Software Development

ETS is the common, manufacturer-independent software for designing, configuring, and commissioning all KNX devices. Developing and supporting this software is one of the association’s most central activities.

C) Certification and the KNX Logo

Through rigorous testing procedures on manufacturers’ products, the association grants the KNX logo to compliant products. This logo guarantees the product’s quality and its interoperability with all products bearing the KNX logo.

D) Training and Certification

By providing educational documentation and certifying accredited training centers around the world, the association trains skilled professionals and standardizes technical knowledge in this field.

E) International Standardization

One of the association’s most significant achievements is the recognition of KNX by major international standardization bodies — including CENELEC (EN 50090), CEN (EN 13321), ISO/IEC (14543-3), the Chinese National Standard (GB/T 20965), and ASHRAE (ANSI/ASHRAE 135).

Today, the KNX Association hosts more than 500 member companies from around the world — a clear reflection of the industry’s broad adoption of this standard.

F) Developer Support

The association provides technical support and consultation for companies intending to develop KNX-compatible products.

G) Promotional Activities

Participation in international exhibitions, publication of brochures, website launches, and other marketing measures to showcase the capabilities of the KNX system.

Key Benefits of the KNX Standard

The KNX standard delivers measurable benefits across safety, energy efficiency, flexibility, comfort, and future-proofing — all supported by a global ecosystem of certified products, qualified professionals, and hundreds of thousands of installed projects worldwide.
