Energy is at the centre of sustainability and has a considerable effect on ecological, social and economic dimensions. As high-energy company with an energy demand of approximately 1,000 households, we recognised the tremendous potential for sustainable actions and started the project LÜDECKE energy campus in 2020.
The Concept “LÜDECKE Energy Campus”
The LÜDECKE energy campus represents a milestone in the development of our company. At the beginning of the project, LÜDECKE was exclusively dependent on external energy supply sources. The building as well as the surrounding rental units were equipped with four separate electrical connections and the heat supply consisted of six partly outdated oil and gas boilers.
Long before the energy crisis in 2022, LÜDECKE drew up a comprehensive concept for a sustainable and future-oriented energy supply at the Amberg site. Within the Green Company Concept, this included the following requirements: in-house energy production, a central heat and cooling supply as well as the modernisation of the entire energy system.
Moving gradually towards a sustainable Future
As a first step, we renovated and enforced the roofs. Subsequently, a photovoltaic rooftop system was installed with a performance of almost 1 mwp. Simultaneously, all buildings of the campus were integrated into the company network via an underground power grid.

The next step was to replace five outdated heat generators with a central solution: an approximately 500 kw cogeneration unit in combination with an absorption cooling unit.

To use electricity surpluses reasonably for heat production, we additionally installed a 100 kw heating cartridge as well as a heat pump. Due to complex power grid work, all buildings were connected to the central supply system via local heating pipes. An energy monitoring system as well as a load management system monitor the consumption and deploy controllable consumers profitably.
Improvement of Energy Efficiency
Significant decrease from purchased energy. To some part, energy is fed into the grid via the energy production facilities. | All these actions led to a considerable improvement regarding energy efficiency. Moreover, the LÜDECKE energy campus is a huge step towards energy independence and supply security by local energy producers. In total, the project took three years from the planning phase to completion. In this period, a new production hall was built using a wooden hybrid construction which accommodates the new energy centre. |
The LÜDECKE energy campus considerably strengthens the positive development of our company in all three areas of sustainability. By implementing an advanced energy system, LÜDECKE is well-prepared for all coming challenges and can look ahead with strong confidence.
