Comfort and energy efficiency realization by the usage of open technologies for home and building control.

Over the last 70 years, technologies have developed in a swift manner. Phones, with higher capacities than the computers, which have been used for the landing on the moon, are now state of the art and further developments can be experienced everywhere day by day. This technological development covers also the electrical components in houses and buildings, dealing with all sorts of applications, such as lighting, shutter control, heating and air-conditioning, as well as security and comfort.



Why Building Automation:


Whilst conventional switching is commonly used for the residential sector, the complexity of those conventional installations escalates rapidly, once further functions, such as simply the switching with two different light switches, shall be realized. Further extension of even higher complexity requires additional devices, such as relays and timers, with additional wiring for each new component.


Needless to say that commercial buildings, such as hotels and offices face higher requirements and complexity, in order to accommodate the needs for each user. Catching up with the technical developments, commercial buildings are becoming increasingly modern, offering automated functions which are taken for granted. The answer, in order to realize the all these automated functions without spending too much time and invest in any vast amount of additional wiring, is building control, in particular with KNX.


The open KNX technology for home and building control found its way into everyone’s life in the year 1990, at which actuator and sensors, each provided with a microchip, are connected via a bus cable. The success of this technology was determined by the possibility to control everything, which runs on electricity in a building as well as its flexible and easy way to program the whole installation. Reprogramming instead of conventional rewiring showed a new dimension in the maintenance of houses and buildings, including conversion of rooms for other purposes, which would require adjusted functions.

What is a standard in the field of home and building control:


In order to transfer control data to all building management components, a system is required that does away with the problems of isolated devices by ensuring that all components communicate via one common language, a so-called “Standardized Open Technology”. Open-Source and Open-Technologies have already proven themselves to serve the users, but also the developers, the best, in order to realize solutions for the needs of everyone. Available free of charge, the openness of KNX has been brought to the world of home and building control.


KNX is based on more than 25 years of experience in the market, amongst others with its predecessor systems ‘European Installation Bus (EIB)’, ‘European Home Systems (EHS)’ and ‘BatiBUS’. Combining all forces, the powerful KNX technology was created in 1990. Opening the doors to this open technologies for manufacturers and installers allowed standardization bodies to implemen
