When it comes to the future of air conditioning, energy and building technology, efficient connecting with security technology must be discussed.
On the first day of the conference, this professional commitment was followed by many interested listeners and active co-discutants from the industry.
The presentations of the 4th Intersec Forum and the discussion sessions chaired by Bernhard Heuvelmann will be summarised here for you briefly:
Semantic interoperability: Platforms & protocols
„Interoperability of intelligent systems in buildings“
Peter Kellendonk, Chairman of the Board of Management of the cross-industry network EEBUS, looked to the topic from the overall perspective of power supply in times of the future comprehensive electric mobility: "All current systems for controlling energy consumption in buildings become obsolete when electric cars are parked and charged in their garages.”
The global expansion of electromobility and renewable energies is leading to major challenges in the operation of buildings. At the Intersec Forum 2019 of Messe Frankfurt, Peter Kellendonk estimated that around five million electric cars would be registered and 20 million heat pumps installed in German households by 2025. An overload of the house connection points is pre-programmed. "In the future, the secure operation of buildings will only be guaranteed if heating, air conditioning and building technology are coordinated with electric vehicles and the power grid," said Kellendonk. This requires a standardised language such as EEBUS, with which all energy consumers and suppliers exchange information. The devices in the building are controlled by the in-house energy management system (EMS). The interface to the energy supplier is via a Smart Meter Gateway. Since each building will have individual energy supply requirements, there will no longer be transfer points with fixed connection lines in the future, but variable limits.

„Interoperability in security technology: control of different systems via a single platform“
A security management system provides a homogenous platform for recording and processing security-relevant events from different parts of the building. Kai Eckstein, Key Account Manager at Advancis Software & Services, cited safety & security installations, building automation systems and communication systems as examples at the Intersec Forum 2019 of Messe Frankfurt. The challenge is to combine the different, partly proprietary, partly standardized protocols and interfaces on a homgenous interface with ergonomic user interfaces.
"The aim is not to abolish existing protocols, but to integrate security-relevant events," says Eckstein. On top of which come the various data formats of Internet of Things (IoT) applications, so that there will still be a lot to do in the future.
„Interoperability and cyber security of connected heating/clima automation solutions (HVAC)“
"Modern connected buildings, right through to IoT and cloud applications, generate considerable added value for everyone involved," stated Bernard Doerstel, Senior Vice-President of ABB and Busch-Jaeger at the Intersec Forum of Messe Frankfurt. At the same time, he pointed out the risks: "To ensure that this value added is not destroyed by hackers, the issue of cyber security must be taken into account from the outset.”
In building automation, numerous devices from the field to the management level are already connected to each other and to the Internet or cloud, and the trend is rising. The likeliness and opportunities of cyberattacks on components, networks or the cloud are continuously increasing. According to Doerstel, it is therefore important to integrate cyber security into the planning process right from the start. Standards and norms such as IEC 62443 provide assistance in this respect, but even then there is no hundred percent-certainty. "The hunt between hackers and security experts will continue in the future," said Doerstel. Cyber security is not a state or a goal, but a continuous process.

Q & A session with the speakers on “Semantic Interoperability: Platforms & protocols”, Chaired by: Bernhard Heuvelmann
The final discussion on Tuesday morning at Messe Frankfurt's Intersec Forum 2019 – chaired by Bernd Heuvelmann – focused on the topic of interoperability. According to the participants, the starting position in Germany and Europe is not bad. More than 95% of the systems are ready to be integrated by using open standards such as KNX, OPC or BACNet.
An even simpler integration is desirable, comparable to the connection of devices to a PC. Above all, it is important to implement user requirements and ensure simple operation. Use case scenarios should be used to check this and not individual data points "from below". The participants agreed that digitisation and the growing market expectations exert great pressure on the further development of building automation, including the implementation of smart buildings.
