GModG · Offices

Lighting control for offices
and administration under the GModG.

Half-empty floors, meeting rooms, long corridors: offices burn a lot of light nobody needs. With sensors on the luminaires, you meet the lighting requirement and hardly notice it day to day.

Larger office buildings can reach the GModG's 70 kW threshold through their central heating or air-conditioning system. Under § 8 GModG the owner is responsible, even if the building is let.

How control works in an office

  • Presence per area: light follows the workplaces actually in use, not the whole floor.
  • Daylight: artificial light is turned down near windows.
  • Corridors and stairwells: base light instead of darkness.
  • Meeting rooms: scenes can be called up with the WP108E wall switch.
  • Quiet installation: sensors sit on or in the luminaire. No ceilings are opened for new control cables.

More than light: occupancy data

The sensors show which areas are used and when. This helps with hybrid working, cleaning and deciding how much space you really need. See Offices and workplaces.

Let buildings

In commercial leases, the contract determines whether costs can be passed on. See Lighting control in let commercial buildings. Changes when tenants move are done in minutes via app, or we take care of them under a maintenance contract.

As of November 2026. General information, not legal advice. The wording of the law is what counts.

FAQ

Frequently asked questions from offices

Will the light keep going off if I sit still at my desk?

That is a common problem with badly adjusted or simple motion detectors. Presence sensors also detect small movements, and the hold time can be adjusted. See Lights keep turning off in the office.

Do tenants have to tolerate the installation?

In Germany, generally yes, as the toleration rules also apply to commercial premises. See the guide on commercial lease costs. Not legal advice.

Do the sensors suit our luminaires?

That depends on the driver. You need a dimmable driver with 0-10 V or DALI. Send us a photo of the rating plate and we'll check it free of charge.

Can users still switch the light themselves?

Yes, for example with a wall switch. We define this per area.
