The measure is intended to protect the climate and promote biodiversity
Since April 1, 2026, Darmstadt has switched off the exterior lighting of public buildings during the summer months. This regulation applies annually until September 30 and is part of the city's adopted lighting guidelines.
The Wedding Tower, the Ludwig Monument and the Güterbahnhof Memorial are exempt from the shutdown.
Contribution to species and climate protection
Artificial light disrupts the natural day-night rhythm and poses a threat to many animal and plant species. Insects, in particular, are attracted to light sources, lose their orientation, and often die. Birds, too, can be disturbed by light and are more likely to collide with obstacles. Bats avoid illuminated buildings as habitats, while small mammals and amphibians rely on darkness to protect themselves from predators.
Environmental officer Michael Kolmer emphasizes that the protection of darkness is an important component of species and habitat protection and has long been underestimated.
Energy savings through reduced lighting
In addition to its ecological benefits, the measure also contributes to energy savings. Switching off the facade lighting saves approximately 30,000 kilowatt hours of electricity annually. This also reduces the emission of climate-damaging greenhouse gases.
Appeal to citizens
The city is also calling on private households, businesses, clubs, and churches to reduce or switch off their outdoor lighting wherever possible. Information and tips on how to implement this can be found in the city's lighting guidelines, which are available online
