The new Leipzig South Combined Heat and Power (CHP) Plant is setting a benchmark for sustainable energy infrastructure in Germany. As part of this forward-looking project, Construction Specialties (CS) supplied high-performance Rain Defence Louvres to ensure efficient airflow and protection—without compromising on design.

About the Project
Built on the site of the historic Ernst Thälmann power station, the plant combines cutting-edge Siemens gas turbines with advanced emissions-reducing technology. With over 93% efficiency, it provides both electricity and district heating to Leipzig—all while meeting strict environmental standards.

The Challenge
To maintain both functionality and aesthetics, the plant required a ventilation solution that could deliver reliable airflow, defend against wind-driven rain, and visually integrate across different parts of the facility.

The CS Solution

CS supplied its RSH-5700AL Rain Defence Louvres, tested to EN 13030 and achieving Class A rain protection at up to 3.0 m/s. A total of 245 m² of louvres were installed across the Main Power Plant, Gas Supply Facility, and Pump House—delivering consistent performance in both intake and exhaust applications.

Seamless integration

The project involved close collaboration with planners and architects to ensure a consistent aesthetic and optimal performance. The louvres were finished in various RAL colours to match each building’s design, helping unify the visual identity of the facility.

Completed in October 2023, the Leipzig South CHP Plant now plays a key role in expanding the city’s district heating network—powered by smart design and reliable ventilation from CS.

Construction Specialties’ (CS) rain defence louvres are providing airflow and maximum rain defence for one of the largest data centres in Europe.

Following a successful acquisition of Hydrokraft AS in 2022, Arkon Energy has started the development of additional infrastructure, aiming to harness the facility’s total capacity potential. Located in Glomfjord, Norway, the centre runs entirely on eco-friendly, economical hydroelectric power.

The focal point of the project was the implementation of a rain defence louvre system that would not only provide efficient intake airflow but also withstand the significant wind load requirements typical of this region. The louvre system had to be both functional and aesthetically pleasing, blending well with the existing envelope design. An additional consideration was selecting a finish that would ensure longevity without impacting cost or lead times.

After a thorough consultation process, the RSH-5700 horizontal bladed rain defence louvre from CS’ architectural range was selected. This model offered the ideal balance of performance (class A 3 up to 3.5 m/s), cost-effectiveness, and visual appeal for customer’s requirements. The final finish choice was a standard polyester powder coat in matt RAL 7035, closely matching the facility’s cladding panels. The finish was warranted for 20-years (subject to a regular maintenance schedule), following an assessment based on site’s location.

The modular nature of the RSH-5700 louvre system facilitated ease of installation, a crucial factor given the project’s scale and location. Its robust design ensured durability and longevity, vital in a region prone to high wind loads. Installed at the building’s front, the system covers approximately 580m2, serving as the primary airflow intake. This solution effectively met the dual challenge of high-level performance and architectural integrity.

Construction Specialties’ (CS) high performance rain defence louvres are providing maximum airflow and rain defence as part of an innovative cooling and power system at two, high-security, energy efficient data centres in Germany.

Controlling the temperature and humidity of the air within critical infrastructure such as data centres is an important consideration. It’s why the Noris Network’s two state-of-the-art data centres in Nuremberg and Munich have adopted an innovative Combined Energy & Cooling Cells (CECC) with KyotoCooling®, offering 70% less energy consumption for cooling and operation compared to more traditional solutions. In order to provide optimum airflow and maximum protection from wind-driven rain within the space-efficient design, the specification for both centres saw the installation of CS Rain Defence Louvres.

At the Munich facilty, CS Rain Defence RSV-5700 Louvres were installed on opposite sides of 10 towers located on the rooftop of the facility. The louvres allow efficient airflow into the towers, while preventing rain ingress on the intake side and letting the air out on the exhaust side.

Following the successful application in Munich, the same louvre model was installed at the Nuremberg South data centre, on the intake side of KyotoCooling cells.

The louvres also met the client’s high security requirements, with the RSV-5700 modules configured to provide RC2 burglar resistance class for additional layer of protection to prevent unauthorised access into the buildings.

Featuring a complex, extruded aluminium blade profile, arranged in a vertical orientation, the RSV-5700 is a space efficient louvre achieving an impressive Class A rain defence up to 3.5 m/s, combined with Class 3 airflow. Its performance has been verified in third party testing to BS EN 13030.

The RSV-5700 system is supplied pre-fabricated in sizes meeting project requirements for fast and easy installation.

With data centres a critical element of our global economy, their functionality and design must never be compromised. The installation of CS Rain Defence Louvres has ensured efficient airflow and flawless weather resistance for the long term.

CS_3In order to provide optimum airflow and maximum protection from wind-driven rain within the space-efficient design, the specification for both centres saw the installation of pre-fabricated CS RSV-5700 Rain Defence Louvres.

Featuring a complex, extruded aluminium blade profile, the RSV-5700 is a 129mm deep, single bank louvre with excellent performance characteristics. Its unique blade shape is designed to effectively separate rain droplets from the flow of air and to collect them in multiple blade channels. The vertical orientation of the blades utilises gravity to allow rain water to drain away easily, helping achieve Class A rain defence up to 3.5 m/s, combined with Class 3 airflow and spacial efficiency. The system is supplied pre-fabricated in sizes meeting project requirements for fast and easy installation.
