2. Introduction
An Intelligent building is the one which provides a productive and cost-
effective environment through optimization of four basic elements:
structure, systems, services and management, and the interrelationship
between them.
It is a type of building that uses both technology and process to create
an environment that is safe, healthy, and comfortable to everyone.
3. Smart/Intelligent buildings:
A smart building is equipped with
• a communications network
• linking sensors
• domestic appliances, and
• other electronic and electric devices
that can be remotely monitored, accessed or controlled, and which provide
services that respond to the needs of its inhabitants/users.

5. What is KNX?
• A truly open system for control in homes & commercial buildings
• Reliable technology for more than 20 years
• More than 10 million installed nodes in tens of thousands of
installations
• Supported by more than 300 members of the KNX Association
• “Programming” by the Engineering Tool Software ETS
7. A KNX highlights
• One touch control
• Lighting
• Dimming
• Curtains
• Air Conditioning
• Security
And more….
Scenes to suit your mood
• Presentation
• Projector
• All On
• All Off
8. System Description Overview
• A bus cable a twisted pair of wires,Ethernet, RF and power line are
also supported.
• Open bus topology, no end-of-line resistors, length of a bus line
including spurs is a
• maximum of 1,000 m
• Approx 15,000 devices on one KNX system.
• Each device gets an individual (physical) address, by which it can be
parameterized and polled.
• The functional assignment between each single device (object) is
achieved by the assignment of group addresses.
15. Advantages of KNX
• One Tool – the Engineering Tool Software ETS™!
• Fit for use in all applications in home and building control!
• Support for different transmission media
• Support for different configuration Modes
• Easy coupling to other systems
• KNX is independent from any hard- or software technology
16. Conclusion
KNX system offers a lot of benefits for operating in modern
residential and commercial buildings. KNX power supply is
a key unit and device to run the KNX system smoothly.
Another KNX unit to enable the electrical devices is an
actuator made with mechanical relays. A well designed KNX
actuator should subject to the corresponding standard
depending on applications to ensure a long and stable
operation with minimized maintenance and service.
