The key to increasing energy efficiency is the intelligent management of all energy consumers, generators and storage units in a stable and reliable overall system. The success factor is networking and the automation of all devices and systems at room level across all trades. This enables user-oriented and energy-optimized control of all consumers and storage units. Of central importance and key to implementation is the seamless integration of the established KNX standard for building system technology into the building automation system. Using the emalytics Framework powered by niagara framwork® as a practical example, the presentation will show how device, system and building data from existing and newly planned KNX systems can be integrated into the building automation system and used to optimize operational management
