OSTRAVA, Czech Republic – Anolis LED fixtures are illuminating both interior and exterior of the central feature at the Nova Karolina Shopping Center in Ostrava. The requirement was for a fixture bright enough to register during the day, and the entire installation also had to be energy efficient and “green.”

OSTRAVA, Czech Republic – Anolis LED fixtures have been specified and installed to illuminate both interior and exterior of the central feature at the Nová Karolina Shopping Centre in Ostrava.
The new 100 million Euro development is one of the largest inner-city development projects in the country. The multi-level environment was designed by architect Har Hollands from Dutch company T+T Design, working with Czech architects K4 from Brno.
The frustum (truncated triangle) shaped centerpiece creates a sense of drama and spectacle right at the heart of the busy shopping space.
Hollands proposed an initial lighting design for the 36.5 by 35 meter conical shape which has a height of 22 meters, and for specification of the right fixtures, main construction contractor Gemo recommended Anolis.
Anolis’ Brand manager Petr Kolmacka produced several options – all of them energy efficient – to achieve the dynamic effect that Hollands wanted. The requirement was for a fixture bright enough to register during the day, and the entire installation also had to be energy efficient and ‘green.’
Mikolaa Parma, head of the Anolis Research Lab at their HQ in Valasske Mezirici, produced detailed visualizations and data for both interior and exterior systems, complete with customized elements to get the exact effects and coverage from the available positions for the lights.
The interior is illuminated with 32 pieces of Anolis ArcPad 94 RGBW EPS, a special fixture with a separate (rather than integral) power supply. These are positioned on four ledges at ceiling height around the base of the space, and the beams focused to cross one another and wash up the space, giving a smooth, even coloration right up the fascias, with eight ArcPad 94s per side.
With all 32 ArcPad 94s on at full, they use 8.5 kW of power, however the standard power consumption (for 97 percent of the running time) is just 4kW for all fixtures on – which is definitely carbon conscious.
Another stipulation was that the lighting scheme should generate minimal heat and not increase the need for extra air conditioning. The Anolis LED scheme once again ticked that box.
Added to that is the long lifetime and the minimal maintenance required, which was essential as the fixtures are difficult to access. They also had to be tightly focused to allow the bottom sections on all four sides of the cone to be used for a projection show that runs all day.
Two standard colors – blue and white – have been programmed initially, representing the corporate colors of the Czech owners / managing company MULTI Development.
Exterior
Outside, 16 ArcPad Xtreme RGBW units with custom optics (half fitted with 23 degree optics and the other half with asymmetric 23-6 degree lenses.) are lighting the exterior of the centerpiece on all four sides – so it can be seen from several kilometers away.
They are positioned on the roof of the complex, approximately 12 meters away, programmed to run five-minute alternations of the same blue and white sequence of colors. These color combinations are not the only ones. Combinations of 16.5 million colors can be selected and the time sequences can also be adjusted if needed.
Both inside and out installations have their own control PC-based Robe CyberCue architectural system controls, which are run in stand-alone mode. The exterior scheme is triggered by a light sensitive sensor when it becomes dark, and the interior lighting switches on when the building opens to the public each day.
Petr Kolmacka remarks, “I am extremely proud to be involved in this project. Anolis is a Czech brand seen in some of the highest profile installations worldwide, and so it is special to see it in action on its home territory. It’s also good that proper attention is being given to the importance of lighting in Ostrava’s on-going redevelopment plans.”
