Thanks to its many rare and vulnerable animal and plant species, Zuidhoek in the municipality of Nieuwkoop in the Netherlands is part of the Natura 2000 network. In 2011 the municipality decided to convert Zuidhoek into a residential area by building 89 houses after assessing the environmental impact this. The research showed that it is an important feeding area for some rare bat species.

the overall

objective was to increase the quality of the darkness and I wanted to find the best light source to achieve that."

Customer challenge


The outcome of the research showed that it is an important feeding area for some rare bat species.


Therefore, before proceeding with the housing program, they had to put some conservation measures in place. This had to include lighting that would not disturb the nocturnal feeding and nighttime activity of the bats.


The right lighting


“The key aspect of the project was to create a natural landscaping concept in which the housing program does not impact local wildlife.” said Robert Jan Vos, the Lighting Design Consultant who made the lighting plan for the residential area.


To further optimize light levels, the municipality installed the Interact City remote light management system to ensure that light is only on when it’s needed. They can now use the scheduling function and set up an annual dimming calendar. The software also enables the municipality to become more proactive in terms of fault detection and maintenance operations. Moreover, it allows fast response to citizen complaints, for example if the brightness of a certain fixture needs to be reduced. Following the successful implementation of the system in Zuidhoek, the municipality is planning to extend it across other areas of Nieuwkoop.


Fully compliant with nature conservation objectives

The application of the dedicated light recipe supports the municipality’s housing program 
in Zuidhoek while enabling the creation of an ideal infrastructure that complies with the directives of Natura 2000.

Maximum flexibility and optimized efficiency

Enabled by the Interact City lighting management software, the municipality has complete 
flexibility to set up dimming schedules and an annual dimming calendar. These ensure that artificial lighting is only used when it’s needed, thereby optimizing energy efficiency.

Creating a livable space for all inhabitants

The new lighting solution ensures bats living in the area are not disturbed by the color and 
wavelength of artificial lighting. At the same time it provides good visibility and an optimal sense of safety for residents.

Operational excellence

Also thanks to the Interact City lighting management software, the municipality can now proactively respond to citizen feedback on the lighting, easily adjust dimming levels of individual fixtures, and perform proactive maintenance.
