"The plan was to save 35 % of energy, but we have achieved over 70 %."
The renovation project
Since 1994, the halls at the main site in Neuss have been heated with a central hot air system using a gas-powered hot water boiler system, which resulted in high energy costs. In order to achieve the company's own ambitious climate targets and increase efficiency, it was decided in 2021 to convert to a modern, decentralized heating system. In collaboration with the engineering firm Enviconsult, a heat demand analysis was carried out and a concept was developed to switch off the old boilers and introduce modern infrared heating.
Requirements and implementation
ATN has been using decentralized infrared heaters from KÜBLER in one branch since 2017. Due to the different areas of use in the halls, the decision was also made in 2021 for a system that can specifically control individual heating zones. Convenient control and high energy efficiency were also important. After reviewing various offers, KÜBLER was again chosen because its system and the CELESTRA digital control system were convincing.
Technical solution
Due to the low ceiling heights, PRIMA infrared systems were installed in the halls and PRIMA plus. These systems offer high infrared efficiency and a good price-performance ratio. The system is controlled by CELESTRA, which automatically optimizes heating operation in the heating zones. The WinTec extension module enables remote control and TorOff reduces energy losses when the hall doors are open. The EMMA energy management system ensures real-time transparency and provides relevant data for reporting, e.g. in accordance with DIN EN 50001.
Results
Since commissioning in September 2022, expectations have been exceeded. The conservative target was 35 percent energy savings, but over 70 percent was achieved. Energy consumption fell from 1,996 MWh in 2021 to 565 MWh in 2023, representing a saving of 1,431 MWh per year. In addition, 97 MWh of electricity and 344 tons of CO₂ were saved. Lutz Obladen, Head of Facility Management at ATN: „The switch to decentralized infrared heating technology is a milestone in achieving our climate goals!“
Experience and conclusion
The old heating system caused high costs and environmental pollution. The new infrared heating system from KÜBLER enables targeted control of the heating areas and significantly reduces energy consumption. The cooperation with KÜBLER was successful, the installation went smoothly and during operation. The employees are satisfied and the system works perfectly. Obladen emphasizes: "The bottom line is that I would do everything exactly the same again."

Ludwigshafen, August 2020 | Decentralized infrared radiant heating systems are the technology of choice in tall buildings with ceiling heights of over 4 meters. Here, they are often functionally superior to alternative heating systems. Their efficiency is so high that they have been able to exceed climate protection requirements for years, even without the integration of renewable energies. They also offer clear advantages in terms of investment costs, as studies have shown. With the entry into force of the GEG, high-efficiency technologies such as decentralized infrared heating systems are finally finding their way into legislation.

The traditional Grün-Weiss Mannheim club is one of the largest tennis clubs in Baden. The club has two of its own tennis halls and thus offers continuous training opportunities for the players. However, heating the two halls from 1952/53 and 1972 was increasingly becoming a financial burden for the club. Between 30,000 and 35,000 liters of heating oil per year were consumed [...]

The old hall heating system consumes too much energy. And it is becoming increasingly unreliable. Good reasons to finally tackle heating modernization and replace the old system with a modern, energy-efficient one. But the expense seems high and is often shied away from. Yet today there are alternative solutions that can also be very interesting from an economic point of view.
