Glossary

Open interfaces refer to standardized technical access points that allow different systems to communicate and exchange data. They enable interoperability between hardware, software, and cloud services without relying on proprietary or manufacturer‑specific systems. Open interfaces are typically based on established protocols such as MQTT, BACnet, or Modbus and make it possible to provide data in a structured, secure, and reproducible manner. As a result, they form the foundation for scalable data architectures in which building information can be efficiently processed and reused.

In the building sector, open interfaces play a key role because modern buildings integrate numerous trades, manufacturers, and systems: building automation, HVAC, IoT sensors, energy generators, and digital services such as ESG reporting or FM software. However, many existing buildings still have isolated systems that are difficult to connect. Open interfaces solve this problem by enabling interoperability across all trades, ensuring data accessibility, and supporting portfolio‑wide scalability and comparability.

With its software solution, aedifion relies entirely on open interfaces, creating an interoperable digital ecosystem for commercial buildings. The platform can integrate data from almost any building system, regardless of manufacturer, age, or protocol. Through standardized APIs, data are automatically transferred from building automation, sensors, energy systems, and other sources into the cloud‑based Data Lake, where they are structured and made available for analysis, AI, and optimization. At the same time, aedifion enables external partners such as FM software, ESG tools, or digital services to securely access relevant data. This makes aedifion’s cloud platform the central data hub that connects systems and enables the seamless use of digital methods throughout the entire building operation.
