Stadtwerke Eichstätt achieved significant energy savings by equipping an underground parking garage with intelligent LED lighting. By replacing more than 145 fluorescent tubes with LED luminaires of the highest energy efficiency class, the annual electricity consumption of the lighting system is reduced from 45,000 to around 11,000 kilowatt hours. This project is supported by supplying the properties of the Eichstätt diocese with Green Electricity-certified green electricity. Part of the costs for the conversion were thus borne by subsidies from the Green Electricity Label. With the label, a fixed amount is invested in new energy transition projects for each kilowatt hour of green electricity consumed. To date, the Green Electricity Label has enabled more than 1,400 projects to be implemented with over 75 million euros in funding.

"The retrofit is a more than sensible investment from an ecological point of view," emphasizes Wolfgang Brandl, Managing Director of Stadtwerke Eichstätt, presenting the new lighting system. Thanks to intelligent motion detection, the lamps are only dimmed up to full power when the garage is in use. The lights are networked with each other via Bluetooth and share the signals they receive. This creates a kind of swarm intelligence, Brandl explains. This technically more sophisticated solution leads to a minimization of the duty cycle and maximum energy savings, he adds. The project saves around 1.8 tons of CO2 per year.

As part of the implementation of its Climate Offensive 2030, the Diocese of Eichstätt has been purchasing Green Electricity Label-certified green electricity from Stadtwerke Eichstätt since 2015. With the climate offensive launched in 2013, the Diocese of Eichstätt aims to reduce its carbon dioxide emissions by 25 percent by 2020 and by 50 percent by 2030.
