Tygron presents colliding stars in Noordwijk

Colliding stars in Noordwijk

Colliding stars? Has the ESTEC center in Noordwijk observed something special in the universe or has a difference of opinion arisen among Dutch celebrities in the area?

None of this. Council members of Noordwijk have something else in mind when they talk about stars: the 2030 Noordwijk Environmental Vision.

Noordwijk is ahead of many municipalities as it has already set up a vision regarding the Environmental Act.

Seven stars have been defined in this vision representing Noordwijk. To find out how this vision can be applied in practice, council members, civil servants and a number of citizens/partners of the city participated in the workshop ‘Impact tests’.

These are the 7 stars:

  • Energetic society
  • Fabulous sports opportunities
  • Attractive and rustic village centres
  • Appealing surroundings
  • Opulent nature
  • Versatile economy and tourism
  • Excellent accessibility

Why an impact test?

In an impact test for the Environmental Act, topics from the Environmental vision or an Environmental plan are reviewed against real cases. The purpose is to test whether the intended vision effectively works as soon as the Environmental Act has taken effect. So this is actually some sort of simulation. There is no fixed format for an impact test; the vision may for example be tested in a role play or in a debate.

The city of Noordwijk asked Tygron to look after all the specific aspects and the effects of the impact-test workshop.

Real time

A real case was reviewed against seven stars in the ‘Impact-Test Workshop’.

Tygron distilled a review model from the Environmental Vision so as to review three scenarios for a re-development location in Noordwijk against four indicators/topics (must comply with the housing vision, noise levels, spatial quality and amount of traffic.

During the evening, the effect of a scenario on the indicators in respect of the original situation was calculated in real time. These indicators are related to one or several stars. Eventually, the score for 7 stars could be visualized in a clearly organized table.

Interactive discussion

With the Tygron Platform, participants were able to set up a clear and unambiguous picture of what happened during the execution of a certain scenario. The model has been built from key data (such as key administrations and the Actual Elevation Model for the Netherlands) and enhanced with the municipality’s own data (such as the traffic model for Noordwijk).

The 3D image made immediately clear to the participants what the urban development plan was going to look like and the impact such a plan may have on the environment. An interactive and vibrant discussion developed from this. And the participants felt like they had landed in 2021, the year when the Environmental Act takes effect, because an integrated consideration of the physical surroundings can be made based on digital instruments and centrally opened-up data.


Of course there was a plethora of different opinions and a lively discussion kicked off: about the mutual relationship among the stars, the testing method, the impact of a scenario on the stars, the use of digital tools and so on.

All in all a successful workshop!
