An energy saving of around 65 percent in the operating state, calculated on the entire lighting, is the result of the complete conversion from halogen lights to energy-saving LED lights at Lake Constance Airport Friedrichshafen.
The halogen lights installed in the past, for example, consumed around 100 watts per light on the center line of the slopes, while LED lights with the same function and intensity consume around 25 watts. That would be due to the fact that LED lamps have a higher efficiency, as they say. Unlike halogen lamps, they do not get warm and thus use the energy with less loss. At the official start of construction in May of this year, the first of a total of 857 underfloor lights embedded in the ground were replaced by LEDs in night shifts. Of these, 366 were renewed on the taxiways and 491 on the runway. The runway lighting was only replaced during night work, while the taxiways were mostly in cordoned-off construction areas during the day.
“After converting the apron lighting to LED, purchasing electrically powered baggage tractors and switching from hall lighting to LED, I am delighted that we have been able to complete another climate protection project. The installation of a total of 857 underfloor lights went according to plan thanks to good coordination with the service providers and construction companies. The lower traffic due to the Corona has made implementation easier. It was a mammoth task, because a total of 1.229 fires were expanded. Due to the higher light intensity of the new fires, it was possible to dispense with double fires in certain areas without loss of intensity. This and, above all, the lower power consumption of the LED lights lead to significant energy savings at the airport, ”says airport managing director Claus-Dieter Wehr.
