Since 2024, the building management department has installed approximately 2,400 kWp of solar panels on municipal roofs. The goal is to have all suitable roofs equipped with photovoltaic systems and to operate them in-house by 2030. Through direct regional marketing, the self-generated electricity remains within the city of Aachen and reduces the city’s electricity costs.

Direct marketing concept
The expansion is particularly economical thanks to the concept of regional direct marketing developed by the City of Aachen's building management.
In the regional direct-marketing model, the city of Aachen acts as the electricity supplier for its own buildings. This makes it possible to supply municipal buildings without photovoltaic systems with “excess electricity” from buildings that do have photovoltaic systems. This helps further minimize external electricity purchases and electricity costs.

This model is now attracting interest from many other local authorities across the region.
Solar Green Roofs
All roofs that have sufficient structural capacity are generally equipped with a photovoltaic system in combination with a green roof. In the context of climate-friendly construction and sustainability, this represents a win-win situation.
Examples of Implementation
Solar Green Roof on Reimser Street
Solar green roof on the locker room building at Auf der Hörn
