What We Do
Astroval runs a certification programme for establishments and observation points, with three quality levels: Bronze, Silver and Gold. Each level represents a greater commitment to protecting the night sky.
We carry out technical audits to measure sky quality using professional equipment such as SQM photometers, all-sky cameras and spectrophotometers. Our measurements follow international sky-protection standards.
We promote smart lighting based on five pillars: usefulness, directionality, intensity, spectrum and timing. We advise companies and public bodies on implementing sustainable lighting systems.
We organise outreach and training activities to bring astronomy to the wider public and raise awareness of the importance of preserving our dark skies.
