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 new 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 pre-fabricated CS Rain Defence louvres.
At the 11,000m2 Munich East data centre, 270m2 of CS Rain Defence RSV-5700 louvre modules, powder coated in RAL 7016, Anthracite Grey, were installed on opposite sides of 10 towers located on the rooftop of the facility. Each tower is housing two autonomous combined energy and cooling cells featuring the rotating Kyoto wheels. CS louvres allow efficient airflow into the cells, while preventing rain ingress on the intake side and letting the air out on the exhaust side. This free flow of air for more than 90% of the year is combined with a power supply from renewable resources to provide energy efficient IT.
Walter Hochstein from CS Germany said: “Due to the very high performance requirements, both in terms of volumetric airflow for the energy-saving cooling system and rain protection, the CS RSV-5700 louvre was selected after successful project specific testing by the building owner.”
Following the successful application at the Munich East facility, 348m2 of CS Rain Defence RSV 5700 louvres were installed at the Nuremberg South data centre on the intake side of KyotoCooling cells. A metallic powder coat finish RAL 9006, White Aluminium was specified to match the exterior façade of the building.
Supplied with bird guards, the prefabricated Rain Defence louvres installed in both facilities also met the client’s high security requirements, with the RSV-5700 providing RC2 burglar resistance class and the required additional layer of physical protection – alongside perimeter protection and video surveillance – to prevent unauthorised access into the buildings.
Featuring a complex, extruded aluminium blade profile, the high performance RSV-5700 is a single bank louvre that is more slimline when compared to other rain defence louvre solutions in the marketplace.
The unique blade profile shape creates the effect of tangential separation to force air entering the louvre to change direction and rain droplets get separated out in the process, collected and drained away.
Its integral front lip gutter and secondary gutters are designed to catch and direct rain water to the cill, providing maximum defence against water penetration whilst maintaining good airflow characteristics.
The vertical orientation of the blades utilises gravity to allow rain water to drain away easily, helping achieve an impressive Class A rain defence up to 3.5 m/s, combined with Class 3 airflow and spatial efficiency.
The system is supplied pre-fabricated in sizes meeting project requirements for fast and easy installation.
All CS louvres are tested at BSRIA to EN 13030:2001 ‘Ventilation for buildings. Terminals. Performance testing of louvres subjected to simulated rain’ to ensure they provide the optimum balance of airflow and rain defence under real world conditions to meet project requirements.
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 at the Noris Network’s data centres in Nuremberg and Munich has ensured efficient airflow and flawless weather resistance for the long term.
