By combining performance, efficiency, and environmental stewardship, the project aims to set a benchmark for responsible and future-ready ski slope lighting.
IMPORTANT CONSIDERATIONS FOR EXISTING LIGHTING Do You Really Need to Re-lamp? If you are operating with existing metal halide, high pressure sodium, or even LEDs, you may be able to lower costs by changing the way your lighting is implemented. These technologies are associated with high in-rush current ; the electricity required to turn on. In-rush current affects your entire electricity bill by increasing “demand charges” imposed by most utilities. In some cases, you can reduce the impact of in-rush by staggering the way fixtures are turned on. There are also capacitor discharge systems that can “shunt” electrical spikes. See section on energy for more details. Design Guidelines and Technical Criteria Proper lighting is essential for night skiing/riding safety, performance, and enjoyment. This section provides comprehensive guidelines and technical criteria for designing sustainable slope lighting systems that ensure optimal visibility while minimizing environmental impact. By integrating standards from the National Ski Areas Association (NSAA), Illuminating Engineering Society (IES), Fédération Internationale de Ski (FIS), and the International Organization for Standardization (ISO), we gain insights on ambient light management, and advanced lighting technologies. This handbook is written to provide a benchmark for energy-efficient, visually effective, and ecologically responsible slope illumination. 1. Illuminance Criteria Illuminance, measured in lux (or foot-candles in the U.S., where 1 fc ≈ 10.76 lux), refers to the amount of light falling on a surface. For ski slopes, emphasis is generally on vertical illuminance —the light striking a vertical plane facing up the slope— which is critical for skier visibility. The following criteria, based on the IESNA RP-6-01 standard developed with the NSAA, apply to recreational skiing :
• Maintained Average Vertical Illuminance: 5 lux (0.5 fc)
