Monitoring of Environmental Light

Luxembourg and Naturpark Our

For the City of Luxembourg, and the Naturpark Our in the northern part of the country, we operate a long-term comprehensive monitoring of environmental light. This includes, amongst others:

  • Night-time cartography of selected sites
  • Detailed analyses of sensitive objects, like illuminated landmarks and industrial plants
  • Supervision of lighting refurbishments
  • Contributaions to workshops and symposia aimed interested and involved parties
  • Operating an All-Sky-Camera continuously recording the nightly sky quality

Estimating potential Light Emissions

For a road construction project in the canton St. Gallen, we estimated prospective light emissions by street lighting and car headlamps. Thus, the project was optimized at an early stage in order to reduce unwanted brightening of neightbouring areas.

Light Mapmaking

Night-time light maps and reports were produced for:
  • Winterthur, Solothurn, St. Gallen
  • Sargans, Ruswil, Birmensdorf, Aeugst a. A., Hausen a. A., Hünenberg, Volketswil, Menziken
  • Toffen (inspections und darkness measurements)
Is this relevant for your municipality? Yes! Since 2021, supervision and potential limitation of light emissions has been federally recommended for all municipalities in Switzerland. Inquire now!

Quantifying Glare Effects

We developed a procedure to reliably quantify nightly glare effect by light sources, using only consumer-grade digital cameras. This puts aside the need of expensive equipment and specific instrumentation.
