THE 55-STOREY Evolution Tower has made a dramatic entrance onto the Moscow skyline – not least for its innovative lighting.
The 255-metre skyscraper is, say the developers, the largest and most efficient all-LED illuminated office building in Russia.
It also features one of the most sophisticated lighting control systems on the planet.
But it’s the dynamic and innovative media facade – believed to be the biggest in Asia – that’s the real eye-catcher.
The project presented the design team some significant initial challenges, not least the combination of a square central concrete core with a floor plate that changes on each floor thanks to the spiral shape of the tower.
‘The challenge we set ourselves was to develop a creative interior lighting design with high visual comfort for employees while achieving an operational load of under 5W per square metre’, says lighting designer Dean Skira.
‘As most rooms are neither rectangular nor square, and the inclination of the glass facade is different on each side of the building on each floor, the concept was for the use of discreet low-glare fittings'.
These are carefully arranged to achieve the uniformity required by the client in the work areas.
It was also important that the illumination from interior lights couldn’t be viewed directly from the outside.
This allowed a clear view of the content on the dynamic media facade.
'We developed what we consider the most sophisticated control system possible’, says Skira.
A Lutron Quantum system is connected to a network of wireless window sensors which track how sunny or cloudy the day is, the shade from other buildings and sun reflection from the Moskva River and other building exteriors.
It also takes information from thousands of occupancy and daylight sensors on all floors.
The system then uses advanced algorithms to control the Dali-dimmable luminaires and the custom roller window blinds to maximise visual comfort and minimise energy use.
It features local and centralised control so the system can be overridden to suit individuals’ preferences.
The result is an extremely visually comfortable interior which delivers an operational load of just 4.8 W/sq m on an installed load of 12W/sq m, a remarkable 60 per cent reduction.
The Evolution Tower is located in downtown Moscow in an area of high visual stimulation and a suitable environment for a dynamic exterior with engaging and harmonious content.
Because of the unique spiral shape and the extremely harsh climate in Moscow (which varies from -40C in winter to 40C in summer) it was not possible to use any equipment on the exterior of the façade.
‘Instead, we designed a special fitting – which represents one pixel of the media facade – to be mounted on the interior window frame mounted flush to the glass’. says Skira.
It was carefully designed so that there is no spill light to the interior and only becomes visible only from the exterior.
Each fitting uses RGBW LED technology to allow infinite scenes. In total, there are 3,500 luminaires representing pixels.
Cabling is hidden inside the railings of the shades so they also become invisible.
