Building automation is on the rise. Systems are becoming more and more advanced and offer more and more service functions. The added value is created thanks to IT-based systems that go beyond what building management systems have been able to offer so far.
It is generally accepted that buildings can be used more efficiently by intelligently interpreting usage data. Existing spaces can be used more efficiently through smart, innovative technology. Energy can also be used more effectively. An investment in smart, innovative technology may then be recouped within a few years. By applying smart and innovative technologies, workplaces can be made more attractive. This has a positive impact on employee productivity. All these factors contribute to a major shift from conventional architecture to “Smart Buildings”. German professor Michael Krödel has published a study on Smart Building trends and made a comparison between different wireless standards for home and building automation. Various IoT options have been mapped out in a methodical manner:
– What sensors are there?
– What connectivity needs does each type of sensor have?
– What protocols for wireless and IoT are there?
– How do those protocols match sensor requirements?
Professor Krödel's findings are clearly presented in a matrix in the report.
In the study, Professor Krödel states that a distinction must be made between room automation and facility automation on the one hand, and value-added services in “Smart Buildings” on the other. The typical space automation and facility automation scenarios are intended to optimize lighting, shading, and HVAC according to temporary requirements. They represent a relatively simple step towards more “intelligent” solutions. Conventional technologies provide little support for more complex, adaptive or self-learning solutions. So-called bus systems rely on a combination of device parameters and interaction between sensor and actuator. This simplifies implementation but does not create truly “smart” buildings. More advanced scenarios require controllers to be programmed.
