TUBULAR LED luminaires which mimic the look of bare fluorescent lamps have proved successful at uniting a listed 1960s swimming pool and a modern extension.
The lighting at the swimming complex in Dresden, Germany, combines the old and new fabric of the building, while reliably satisfying the needs of both competitive and recreational swimmers for good visibility.
With the construction of a new competition hall and the renovation of the old hall from 1969, Dresden has the second largest swimming complex in Germany.
With its sweeping roof made of prestressed concrete, the old swimming hall is one of the outstanding examples of East German architectural modernism and has been a listed building since 2008.
The necessary renovation proved to be difficult, as it was the only hall with a 50-metre pool and was therefore indispensable, especially for competitive sports in the city.
The solution: The construction of a new 50-metre indoor swimming pool in the immediate vicinity.
IIn conjunction with the neighbouring diving centre, the consortium of Code Unique Architekten and Dähne Architekten created a completely renovated and extended swimming centre with central access in their roles as general planners.
For the lighting of both the new and the renovated swimming pool hall, the designers needed luminaires that could permanently withstand the special ambient conditions in pools such as heat, humidity and a corrosive atmosphere containing chlorine, while at the same time meeting the special lighting requirements of swimming.
In the renovated hall, the lighting is integrated into the rhythmically structured, restored original ceiling cladding made of metal grids and panels.
For this purpose, the designers chose Zug LED tubular luminaires from Norka in the special length of 1,200 millimetres, in keeping with the existing ceiling louvre structure.
As is customary in swimming pool construction, the lighting is positioned to follow the pool contours so that maintenance can be carried out easily.
As slim, linear light sources, these luminaires emphasise the elegance of the 1960s roof construction, breathing new life into the spirit of this architectural era.
Two each of the total of 172 tubular luminaires are combined in a mounting frame; 30° lenses focus the light and allow it to be directed onto the relevant area in use.
With polymer as housing material and special mounting elements, also made of polymer, corrosion is not an issue even in swimming pool air containing chlorine.
The designers used more than 300 of the flat, rectangular München LED luminaires in the new 2016 building to match the functional, sporty and elegant interior design with exposed concrete surfaces and differentiated white tones.
As recessed luminaires, they are mounted flush with the ceiling – both in the competition pool and in the training pool area with its charming maritime wall mosaic, which was saved from the demolished old building.
In the competition hall, asymmetric beam versions produce illumination levels of up to 500 lux at water surface level from the pool periphery, thus meeting the requirements for international sporting events.
The efficient LED luminaires have DALI-interfaces for integration into the control technology of the entire building, which means brightness levels for training, school and recreational swimming can be reduced as required – as well as saving energy.
München LED luminaires are also installed above the spectator stands, in this case, however, with medium beam characteristics and concealed behind a white ceiling louvre.
This protects the audience from glare and creates a softer lighting character that separates the two zones of the room to suit their purpose.
The colour temperature used throughout the room is 4000K, which harmonises perfectly with the daylight entering through the large window areas.
To ensure that this harmonious atmosphere is not spoiled by a fussy ceiling, the safety lighting in the swimming pools is not provided by separate luminaires but is integrated into the general lighting system.
For this purpose, some of the luminaires were equipped accordingly and connected to the central battery.
