Independent advice on building controls and the Dutch BACS requirement

Degero advises owners and managers of offices, hospitals, schools, museums and other non-residential buildings in the Netherlands on building management systems (BMS), building controls and the Dutch BACS requirement (GACS). Founded in 2008 by Tim Grootes, based in Krommenie, north of Amsterdam. Degero is not an installer: no hardware sales, no brand commission, no installation revenue.

The Dutch BACS requirement explained Contact Degero

When Degero is a good fit

  1. You own or manage a non-residential building in the Netherlands and want to know whether the BACS (GACS) requirement applies, and what needs to happen. Start with the requirement explained.
  2. An existing BMS (for example Priva, Siemens Desigo, Honeywell, Sauter or Webeasy) does not work as agreed: comfort complaints, faults or unexplained energy use.
  3. An installer has sent a BMS or controls quote and you want an independent second opinion before signing.
  4. Your organisation has no controls specialist of its own and wants ongoing technical oversight at a distance.

Not a fit: if you are looking for an installer who supplies or mounts BMS hardware.

Services

All services are delivered in the Netherlands. Detailed service pages are in Dutch; you can contact us in English.

For international owners, funds and property managers

Many Dutch offices, logistics buildings and hotels are owned by foreign investors and managed from abroad. The Dutch BACS requirement sits with the owner, also when the building is leased. Degero can act as your independent technical counterpart in the Netherlands: we check what the installed systems really do, document the evidence, and review installer proposals before you commit.

GACS Scan app (Dutch-language)

GACS Scan is a self-scan app for iPhone and Android. You walk through the building, photograph rating plates and BMS screens, and record evidence along the RVO checklist. The app tracks outputs, photos and open items and produces an A4 report. Download, walkthrough and preview are free; the report is unlocked in the app. It is indicative evidence, not a certificate, an inspection or an RVO statement.

The app is currently available in Dutch, in the Dutch App Store and on Google Play.

About Degero

Tim Grootes, founder of Degero

Tim Grootes started Degero in 2008 in Krommenie. Since then he has worked with owners, facility managers and installers on building controls, building management systems and GACS, having worked on both sides of the table: as client and as installer.

Degero is not a brand shop. The question is always whether the technology in the building does what was agreed: what is installed, what is already measured, and who acts on a deviation. Decisions and evidence stay usable for the owner, the building manager and the contractor.

  • Since 2008 in Dutch non-residential buildings.
  • No hardware sales, no commission on any brand.
  • Works with what is installed: Priva, Siemens, Sauter, Honeywell, BACnet, KNX, Modbus and more.

Frequently asked questions

What does Degero do?

Degero is an independent consultancy for building controls, building management systems (BMS) and the Dutch BACS/GACS requirement in non-residential buildings in the Netherlands. Degero assesses, specifies, guides and checks; the installer carries out the work.

Does Degero sell or install BMS hardware?

No. Degero sells no hardware, takes no commission on brands and has no installation revenue. That is why we can say that optimising the existing system is enough, when it is.

Which systems does Degero work with?

With whatever is installed, including Priva, Siemens Desigo, Honeywell, Sauter and Webeasy, and open protocols such as BACnet, KNX and Modbus.
