Why Use KNX?

Landscape_merged
KNX is an international building control standard that enables the integration and programming of a range of products from many manufacturers using a single software tool.

KNX is the world’s only open standard for building control and automation and can make major energy savings of up to 60%, significantly reducing the carbon footprint of a building. This is truly green sustainable technology that can be applied to small and large buildings alike.

KNX the Standard is approved as:

  • European Standard (CENELEC EN 50090 and CEN EN 13321-1)
  • International Standard (ISO/IEC 14543-3)
  • Chinese Standard (GB/Z 20965)
  • US Standard ( ANSI/ASHRAE 135)

The standard has been adopted by many international manufacturers who together provide a vast array of KNX certified products for a range of building control applications including lighting, HVAC, intruder alarms, audio visual systems, household appliances, blinds/solar control and automatic window control, facade management, energy management and control, metering, monitoring applications.

The main advantages of KNX are:

  • It is an International Standard and therefore future proof
  • By product certification, KNX guarantees interoperability and interworking
  • KNX can be used for all applications in home and building control and fit for use within buildings of all types
  • KNX supports several Communication Media
  • KNX can be coupled to other systems
  • KNX is independent from any hardware or software technology

Choosing from this pool of technology,KNX Integrators, KNX Specifiers and KNX Developers can build entire control solutions by bringing together a variety of off-the-shelf components which are truly interoperable and are programmed using the ETS software tool.   As the products all ‘speak the same language’ and can operate together across the same network, this results in less cabling and higher functionality.

Since KNX covers such a diversity of applications using one standard, it means that cabling network can be much simpler.  KNX controlled devices are generally based around the standard green KNX/EIB bus cable (i.e. twisted pair) but can be run across radio bus (wireless), ethernet (structured cabling), fibre optics and occasionally power line.

KNX is increasingly being heralded by specifiers and end users as a highly desirable open solution for any building control application. The drawbacks of proprietary solutions or various hardware-based controls are being increasingly recognized.  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 couple of 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.

For the developer control systems are a vital part of the modern building or home. They are a highly cost-effective way of preserving energy and provide added value for the developer and an enhanced experience for the building users.

In terms of energy conservation, it is vitally important to make the most effective use of the world’s limited energy resources.  A control system is a highly cost-effective way of ensuring energy use is conserved.  For instance, a KNX lighting control system can be simply configured to only put the lights on when someone is present in the room, and can monitor natural daylight levels to dim or turn the lights off when enough ambient light is present.

When it comes to user experience, technology is moving very rapidly, as indeed are users’ expectations.  In the residential market, features we might expect in a high specification hotel are finding themselves installed in residential developments.

Facilities managers in commercial premises are being provided with ever more sophisticated solutions for the control of their environments.

Flexibility is a particularly strong benefit of a KNX solution.  Needs change within a building’s environment and a flexible control solution allows these changes to be made with minimal disruption. Modern buildings are always being adapted and changed to suit the occupants’ current needs and business activities. With this in mind, the control system needs to be flexible.

With KNX, problems of the past such as disruption, rewiring, wastage or added hardware are no longer a concern – with KNX a system can be simply reprogrammed by an engineer with a laptop. Now project briefs can be more guideline based, since the control systems provide the flexibility to cover a wide range of needs at little or no extra cost.
