The convergence of building services with the Internet of Things and IT-based solutions is changing the "building" system. A far-reaching networking of different sensors and actuators in intelligent buildings creates new approaches, among other things, in the maintenance of the building through data analytics methods. Intelligent buildings can use machine learning to save energy, and predictive maintenance can be used, for example, to plan elevator maintenance more proactively. At the same time, the growing system complexity of smart buildings also creates new challenges for the planner and operator of such buildings. In this seminar, you will learn how to better assess the opportunities, but also the challenges, of networking and digitization in smart buildings. You will also receive a comprehensive overview of the basics of smart buildings and smart homes, practical feasibility and the topics of data security and data protection. In the end, you will be able to understand the building of the future as part of overarching systems such as the "Smart City" or the "Smart Grid" and better assess the various technologies.
