The digital twin is a digital image of tangible or intangible objects. But there are also digital twins of processes or services. In manufacturing, for example, digital images of machines over their entire life cycle are an established procedure and enable more efficient, more flexible and faster production. In construction and smart building management, the digital twin is the cornerstone for automated processes, energy savings and predictive maintenance. To implement a digital twin, large amounts of data from the physical twin are collected with the help of IoT products and platforms and then processed in a clear, vendor-neutral and uniform manner. Based on the data, users can use the virtual model for simulations, find and correct functional errors, and also derive predictions about future behavior. The valuable findings from the digital world can then be transferred one-to-one to the real object. Building operators can monitor and control structures in real time. This also makes automated service processes in facility management possible. The forward-looking technology of the digital image of a building enables the networking of complex building structures in functional buildings and opens up new ways in building optimization. With the aedifion cloud platform, you can quickly and easily obtain a holistic operating picture of your building and digital twins of your facilities. Thanks to its smart plug-and-play approach, the platform helps you to bring your entire building technology into the cloud in the shortest possible time, thus creating maximum data transparency. You can reduce energy consumption and CO2 emissions as needed and automate processes with the help of artificial intelligence.
