Digitalization in buildings and sites is advancing rapidly. Whether through new technologies such as IoT, BigData, Artificial Intelligence, BIM, etc. or due to the incentives of new framework conditions, such as the Energy Strategy 2050 or the revision of the CO2 law, which among other things aim to decarbonize the building stock.

To ensure that the new technologies can be used to achieve the desired goals, fundamental questions about interoperability, data protection and cyber security - which are increasingly acting as barriers - must be increasingly addressed. Existing barriers to system integration should be identified and addressed in a practical manner. The interdisciplinary cooperation of the individual trades, disciplines and technologies must be brought into focus in order to achieve the desired quality, security and effectiveness in the use of technology.

As part of the "Connectivity in Buildings" project, existing specifications such as standards, norms or guidelines are analyzed for existing gaps, overlaps and ambiguities, and the necessary overview is provided in the complicated standards landscape (big picture). Where possible, existing international specifications and regulations are also taken into account.

The interests of all relevant stakeholders and in particular of the building operators are just as important as the technology and are identified in a market and needs analysis on the subject of connectivity in buildings. They will be contrasted with the existing regulations and influencing factors, and the consequences in terms of gaps and necessary regulations will be derived from this. In the future, a guideline based on the project results should combine existing regulations into a comprehensible whole and supplement them where necessary. It should serve as a sustainable basis for improving cross-disciplinary understanding of digital functions and processes between the trades, disciplines and technologies in the building and for strengthening networking within the stakeholder groups.
