What Is KNX?

KNX is the worldwide standard for home and building control. Whether in a residential, commercial or industrial building the automation of heating, air-conditioning and lighting systems is essential for energy efficiency and maximising user convenience and safety. This is where KNX comes in. The KNX system allows all components to communicate together creating a dynamic building management system. With over 450 manufacturers conforming to the KNX standard the flexibility and choice available is unmatched.  

This future-proof system is not only beneficial to architects, designers and contractors during all stages of a project but also the building owners and end users upon completion. The benefits of using a KNX system include:  

  • - Lower operating costs
  • - Time saving installation
  • - Project scalability
  • - Increasing end user wellbeing
  • - Carbon emissions reduction
  • - Reduced wiring

Automated control of the following applications is possible with a KNX system:


Blinds & Shutters


Energy Management


Monitoring Systems

Remote Control


Audio / Video

KNX for:

Home Owners

The public demand for building automation is now common place in the residential sector. With a KNX system this can not only be achieved easily but cost effectively. With simplistic installation, complete home control can be realised maximising user wellbeing and energy efficiency. With the user-friendly KNX interface you can control a vast array of applications with a touch of a button, in or out of the home.

• Benefits for user wellbeing

Enhancing user wellbeing is a clear advantage of a KNX system. All devices in your home can communicate offering complete control and personal specification. With pre-set scenes you can tailor your home to meet your regular and changing needs. Want to settle in for the night and watch a film, activating your movie scene can dim the lights, close the blinds and switch on the tv all with one touch of a button. Or heading out for the night and plan to come home later than normal, boost your heating on your way home and switch on the outside lights so your driveway and front door is well lit when you get back.

• Benefits for energy saving

With a KNX system you can maximise the energy efficiency of your home. No-one wants to spend money heating or cooling their home when they aren’t in, and with a KNX system you don’t have to. For example, with presence detectors communicating with your heating / cooling system the temperature in individual rooms can be controlled automatically to ensure there is no energy wastage on uninhabited areas.

• Benefits for security

Feeling safe and secure in your home is important for everyone. With a KNX system you can actively monitor your entire home or specific areas at home or on the move. We have all had the panic of feeling like we have left the iron on after leaving the house. With a KNX system you can simply log into your home control interface and double check, and even switch specific plugs off remotely if needed. When you are away for the weekend or on holiday you don’t want to rely on your neighbours to keep an eye on your house. With a KNX system any water / gas leaks are recognised and reported instantly, long before irreparable damage can occur. Or your garage, front door or a window are opened or broken without approved entry, an email alert will be immediately sent you to report the incident.

• Future-proof

One of the main benefits of the KNX system is the future-proof nature of its infrastructure. With both forward and backward compatibility you can confidently commit to a KNX system in the knowledge that your system will not be obsolete in a few years, a common problem with single brand control systems. With easy system alteration procedures, you can also add upgrades or change the functionality of the system to accommodate varying requirements without extensive redesign or retrofitting. This not only increases the life-cycle but also cost effectiveness of the system.


One of the most important factors with building control and automation is knowing that support is always to hand and that the system will not be obsolete in a few years’ time. With KNX this is guaranteed as there are approved and trained companies all around the world offering support at all levels for projects small and large, from a small house to an international airport.

With over 450 manufacturers conforming to the KNX Worldwide Standard all KNX products guarantee forward and backward compatibility. This means you can specify KNX solutions with the knowledge that you not only have the flexibility of extending or modifying installations easily but that every product meets the highest level of production and quality control.


Control systems are a vital part of the modern building or home. They are a highly cost-effective way of preserving energy, provide added value for the developer and offer an enhanced experience for the end user. Control systems are now required by legislation, such as the building regulations Part L, and many of these requirements can now be met using the KNX standard.

A key advantage for the developer in choosing a KNX system is the open protocol control infrastructure. Comparing this to a proprietary control solution where you are restricted to one brand which can be problematic for the life-cycle of the proprietary system, the KNX system future-proof.

Integrators / Contractors

By choosing the KNX Standard as the backbone for your control solution, you open a world of opportunities. Some of the most highly respected electrical manufacturers in the world are committed to KNX meaning you can offer your clients a whole spectrum of future-proof control solutions.

As the KNX system covers such a diverse range of applications it means your cabling network can be much simpler. A single twisted pair cable can often suffice, with multiple elements all operating together on a single network. This combined with the option to use various communication media, such as IP and radio frequency in one system, a KNX installation overcomes problematic standard wiring restrictions common in certain buildings.

A number of manufacturers have also developed ‘gateways’ to other control protocols, such as DALI (Digital Addressable Lighting Intelligence) as additional options to expand the capability of the KNX system.

Assisted Living

KNX can help to provide the exact type of support needed in everyday life. It is ideal for the elderly living at home as well as for applications within properties such as residential care homes, nursing homes and other multi-occupancy accommodation. The KNX system not only increases user well-being and allows for optimised room conditions but increases the level of security, safety and emergency response that can be installed, within both private and communal spaces.

With regular alterations in room/area function and inhabitants with fluctuating levels of health the adaptability of the KNX system is a clear advantage. With minimal alteration the functionality of a device, room or system can be changed ensuring an optimised level of support is always provided.
