Energy savings with new lighting system in Selva di Val Gardena
The Wolkenstein Ice Rink in South Tyrol is used for training sessions, Alps Hockey League matches and figure skating competitions. The municipality of Wolkenstein commissioned ewo to replace the rink’s lighting system, with without changing the preexisting luminaire positions: Previously, the hall had 1000 W standard luminaires, but they became old and outdated, requiring repair three to four times a year.
An additional requirement was to reduce energy consumption. The new luminaires were to have an average illuminance of 850 lux, with uniformity of U1 0.7 and U2 of 0.6, irrespective of installation height, operating at 5700 K and CRI ³ 90.
To meet these requirements, 40 R–System gen3 R2 floodlights were used, all the same size and equipped with the same lenses. The driver was mounted to the luminaire body and the luminaires demonstrated excellent thermal regulation performance.
The AH02 symmetric lenses are ideal for lighting interiors, making them perfect for this project. As always with ewo products, other lenses can be used in the luminaires, in combination if necessary, such as those with asymmetric distribution for multidirectional illumination.
The lighting system was also equipped with Smart Lighting, allowing it to illuminate the ice rink with a variety of different dimming levels, switching scenes depending on use. Replacing the existing luminaires not only improved the uniformity of the light, but also reduced energy consumption by 20%.
