New gymnasium in Delkenheim: starting signal for a modern sports center!

New gymnasium in Delkenheim: starting signal for a modern sports center!

The Karl Gärtner School in Wiesbaden is about to take a big step into the future. On November 4, 2025, the magistrate decided to replace the existing sports hall, which can no longer be renovated, with a modern double-deck gymnasium. This new building not only brings a breath of fresh air into the creative sports landscape, but is also a response to the growing demand that has arisen due to the primary school's permanent 3.5-speed all-day operation.

The new sports complex is being realized in close cooperation with the Delkenheim gymnastics club. Construction on the gymnasium is scheduled to begin next year, with commissioning scheduled for 2027. In total, the new building, including demolition costs, will cost around 10.52 million euros. Here, a good hand is invested in the local sports infrastructure.

Sustainable energy supply in focus

A special highlight is the integration of a photovoltaic system into the new building. This measure was coordinated with the Environment Agency and is classified as climate-relevant in order to support the CO₂ savings goals. The installation of solar systems on the roofs of municipal buildings, as is also advocated in the current planning context, brings many advantages and is viewed as economically attractive. Such measures not only contribute to climate protection, but also improve the municipalities' land footprint and reduce electricity costs in the long term.

Public construction sites such as schools and gyms are ideal for using renewable energies. They have large, easily accessible roofs that are often already maintained. This means that the high electricity consumption of public buildings can be efficiently covered during the day, resulting in a quick amortization of the investment. This is an important step on the path to an energy self-sufficient municipality that should be actively supported by citizens and companies.

A look at the challenges

Despite the positive aspects, there are also hurdles in expanding photovoltaic systems. Fluctuating feed-in tariffs, a lack of personnel capacity or expertise, as well as monument law requirements often limit the options of municipalities. Clear political will and forward-looking planning are required here to fully exploit the benefits of these sustainable energy projects.

With the new sports building and the sustainable energy supply planned in parallel, Wiesbaden is laying the foundation for a sustainable community. The involvement of citizens and the use of local cooperative models could further strengthen the project and increase acceptance among the population. Any measure that reduces CO₂ emissions is not only good for the individual wallet, but also for the environment.

Overall, there is a lot to do, but the course is set correctly: building the new sports hall is not just a sporting project, but also an ecological one.
