Vienna – AUSTRIA

A place Vienna is the national capital, largest city, and one of nine states in Austria. Vienna is Austria’s most populous city and the 6th-largest city by population in the European Union, with about 1.9 million inhabitants. The city is the cultural, economic, and political centre of Austria. It is known for its high quality of life: in 2005, the Economist Intelligence Unit ranked the city of Vienna first among the world’s most livable cities.

A need The city of Vienna decided to convert 160,000 fixtures from traditional light sources to energy-efficient LED luminaires as part of its Smart City Framework Strategy, which aims to reduce the city’s energy consumption by 30% by 2030 and by 50% by 2050. The Department of Public Lighting drew up the requirements for a new luminaire. In addition to reducing energy consumption, facilitating maintenance, and preserving the environment, a key factor was the ability to light the many different sites and districts in the city - that need multiple lighting distributions - with one unique design.

A Schréder STUDIO solution Schréder STUDIO rose to the challenge by developing a bespoke luminaire, called Vienna Round, to meet all of the strict criteria. A specific variant was necessary for the catenary installation. At the same time, two different sizes have been installed on the street poles - 66,500 large models and 33,500 small models - to suit the different needs throughout the city. They have created a harmonious aesthetic coherence, both by day and at night. Fitted with the latest LEDs and technology, the energy-efficient Vienna Round is compatible with the city’s own management system. The lighting is dimmed according to preconfigured scenarios to reduce energy consumption while guaranteeing visibility during the night. Indeed, the city has managed to reduce its energy consumption by 65%. This futureproof luminaire also integrates sensors that detect vehicles and people so that the lighting can be automatically adapted to what is needed. Made of recyclable materials and fitted with interchangeable components for easier and more cost-effective maintenance management, the Vienna Round will play its part in helping the city to build a circular economy. The city is delighted with the new lighting, which ensures intelligent and responsible management of its lighting infrastructure while upholding the high-quality public lighting that its citizens have come to expect.
