Anolis helps Ostrava create new identity

Once a heavily industrial city, Ostrava in the Czech Republic is reinventing itself as a centre of innovation and creativity. Anolis was on hand to provide the illumination.

An energy saving Anolis LED lighting scheme has been installed to highlight the famous City Hall Tower in Ostrava, the third largest city in the Czech Republic and the administrative hub of the Moravian-Silesian region.

The city has a strong commercial heritage based on the heavy industries that grew up around its high quality black coal deposits, discovered in the late 18th century. More recently it has launched a big initiative to clean up the environment and control the many years of accumulated pollution, reinventing itself as the ‘City of Colours’, highlighting its equally rich history as a centre of innovation, creativity and education (as a major university city).

This, the city’s first civic lighting scheme, is part of the process of helping to create a new cultural identity for Ostrava. Its numerous creative and entertainment-based activities include a high profile annual arts festival and four leading theatres; its sporting achievements offer up famous football and ice hockey teams.

Ostrava City Hall in Masaryk Square is the largest such municipal building in the Czech Republic with the highest tower at 85.6 metres high, and was inaugurated in 1930.

The tower’s unique steel frame is clad in copper and weighs 155 tonnes. An observation deck at 73 metres offers commanding views of the city, and there is also a clock on each of the four fascias just below the viewing platform.
Anolis proposed that the four fascias of the tower were each illuminated with a single Anolis RGBCW ArcPad Xtreme, one of the most powerful Anolis LED flood fixtures currently available.

According to the company, just one ArcPad Xtreme is all that is needed to evenly light the entire surface area of each elevation – even given the challenging texture of the copper cladding for illumination. These are washed with a selection of colours, including the standard day-to-day selection which is a combination of eight cyan, blue and white scenes, based on the colours of Ostrava’s logo and other colours stipulated in the client’s specifications.
The City Hall also has the flexibility to change the colour of the Tower for special occasions like festivals and other public events.

The Anolis ArcPad Xtreme is a special outdoor fixture with two independent LED modules. The LEDs are densely populated, providing a bright light output, and an IP 67 rating makes it appropriate for exterior applications.
Secured around the top of the observation deck are 20 units of Anolis ArcLine Outdoor Optic 40MC (multi-chip), so the top can either be matched or contrasted in colour to the elevation of the tower.

Two Anolis ArcPower 360 drivers power the LED units, which are controlled by a Cyber Cue system, pre-programmed with the sequences that change every 30 seconds.

The lighting is programmed to switch on at dusk and off at dawn, and runs through the night.
