GACS obligation: quick scan and guidance

Find out whether your building meets the building automation obligation, and what is needed if it doesn't.

In short

The essentials at a glance

Since 1 January 2026, non-residential buildings in the Netherlands with a heating, air-conditioning or combined ventilation system of 290 kW or more must have a building automation and control system (GACS). From 2030 this applies from 70 kW. Hasibo assesses compliance with a GACS quick scan and guides implementation.

Basis: Dutch Bbl building decree, EU EPBD

What is a GACS?

A building automation and control system (GACS) automatically monitors and controls a building's technical installations, such as heating, cooling and ventilation. It must continuously monitor, compare and analyse energy use and flag deviations. The obligation stems from the EU EPBD directive and is laid down in the Dutch Bbl.

1
Inventory
We map the installations and their rated output and check which control and monitoring systems are in place.
2
Assessment
We assess whether the building falls under the obligation and whether the current system complies.
3
Action list
You receive a clear list of missing elements and next steps.

Implementation guidance

Building not compliant yet? We turn the quick scan into a feasible implementation plan, coordinate with suppliers and installers and take care of documentation. Optionally combine it with the commercial energy label.
