At ISH 2027, taking place in Frankfurt from 15–19 March, the focus will be on how heating, cooling, ventilation, water, lighting and building automation can work together more effectively.

The move towards greater integration reflects the growing complexity of modern buildings, with planners increasingly looking at how individual systems – including water and bathroom services – can share data and operate as part of a wider building-management system.

Building automation is at the centre of this shift. In large buildings, thousands of data points can be generated across different systems. Dr Peter Hug, managing director of the Building Automation Association within VDMA, says large buildings can have 40,000 or more data points, many located above ceilings, in basements or on rooftops.

For planners and engineers, the challenge is no longer simply specifying individual systems. They also need to consider how those systems communicate, what data they provide and how they connect to wider control and management platforms.
