In the quiet Alsatian town of Colmar, badminton players at the Gymnase du Grillenbreit are growing increasingly frustrated with a recurring technical issue that interrupts their matches and training sessions: the gymnasium’s lighting system shutting off prematurely due to misconfigured access badges.
According to multiple local players and club officials who spoke on condition of anonymity, the problem has persisted for several months, disrupting evening play when natural light fades and artificial illumination becomes essential. The issue stems from the building’s automated lighting controls, which are tied to a badge-based access system designed to conserve energy by turning off lights when no authorized presence is detected.
However, players report that the system frequently misreads occupancy — particularly during doubles matches or when athletes move between courts — causing the lights to extinguish mid-rally. “You’re in the middle of a point, smashing for the winner, and suddenly it’s pitch black,” said one regular user of the facility. “It’s not just annoying — it’s a safety hazard.”
The Gymnase du Grillenbreit, operated by the Ville de Colmar’s sports department, serves as a key hub for amateur and competitive badminton in the Haut-Rhin region. It hosts weekly league matches, youth training programs, and regional tournaments sanctioned by the French Badminton Federation (FFBaD). With over 150 registered players using the facility weekly, according to club estimates, the lighting failures have tangible consequences for participation and performance.
Technical staff at the venue acknowledge the issue but cite budget constraints and outdated infrastructure as barriers to a quick fix. “The lighting system was installed over a decade ago and integrates with a legacy access control platform,” said a municipal facilities manager during a recent community meeting. “We’ve received complaints, and we’re looking into recalibrating the motion sensors and adjusting the timeout settings, but any significant upgrade requires budget approval that hasn’t come through yet.”
Players have attempted workarounds, such as tapping badges against readers more frequently or stationing someone near the sensor zones, but these are inconsistent and disruptive to play flow. Some have resorted to bringing headlamps — a makeshift solution that draws bemused glances but underscores the seriousness with which they take their sport.
The situation highlights a broader challenge faced by many municipal sports facilities across France: balancing energy efficiency initiatives with the operational needs of user groups. Although automatic lighting controls reduce costs and environmental impact, their effectiveness depends on proper calibration for the specific activities they serve. Badminton, with its rapid lateral movements and intermittent player positioning, presents unique challenges for occupancy detection systems designed for steadier foot traffic.
Local badminton clubs have formally requested a meeting with Colmar’s sports services department to discuss potential solutions, including temporary overrides during booked hours, manual lighting controls for scheduled events, or a phased upgrade to more responsive sensing technology. As of late April 2024, no timeline for intervention has been publicly announced.
For now, the shuttlecocks keep flying — but only as long as the lights stay on.
Next checkpoint: The Ville de Colmar is expected to review facility maintenance requests during its quarterly sports infrastructure meeting in mid-June 2024, where the Grillenbreit lighting issue may be formally addressed.
