Götaplatsen in Gothenburg has been named as the winner of the Swedish Light Award. According to the jury reasoning light setters have coordinated the need for security, performance and experience, and fortified the site's ranking with this skillful lighting design. They have created a urban space where the ambition to direct light has succeeded so well that it feels as light HAS always been there.
In 2011 Götaplatsen, which is one of Sweden's most famous places underwent a facelift with a focus on lighting. The vision was to create a beautiful room, reinforcing buildings around the site and do Götaplatsen to a venue evenings.
- The price is really a recognition of the changes at Götaplatsen. After 20-30 years of discussions now the square got the light it deserves. Today, people still linger on Götaplatsen for a theater to talk and socialize. Earlier they searched the most rapidly away from the dark place, says Ingemar Johansson from the Traffic Office in Gothenburg City.
The prize was awarded for the 19th time in the Light Day on 20 September in Stockholm.
Lighting system and fittings are carefully integrated into the site's architecture. Electrical installations are executed with great finesse and coordinated the need for security, performance and experience, besides fortified the site's ranking with skillful lighting design. Götaplatsen has become a urban space where the ambition to direct light has succeeded so well that it feels as light has always been there.

Feedback from the ESOLi project on intelligent street lighting
The European project, ESOLi (Energy Saving Outdoor Lighting), which aims to promote intelligent solutions for street lighting, held a conference in Frankfurt on the 17th of April 2012. Sabine Pillar, from the Berlin Energy Agency tells us what was discussed.
What knowledge has the ESOLi project gathered on intelligent street lighting (ISL), and how can this help municipalities?
The project offers information and advice to municipalities on specific public lighting issues and supports them by developing a series of practical tools. Now we are in the second part of the project duration and some of the results achieved include a best practice catalogue, over 30 national workshops, and an international conference training seminar. This year we will organize 2 study visits and 14 training seminars on ISL all over Europe.
What are the major challenges faced by cities in implementing intelligent street lighting?
Usually the biggest obstacle is that municipalities do not have sufficient funds to face the initial investment in ISL, although a lot of them are aware of the long term benefits. The public lighting systems are very often old, and ISL requires renovations and high investment costs.
The payback period is variable but usually more than 5 years, depending on many factors, although savings on the electricity bill and on lower maintenance cost are immediate, as are the social/environmental benefits. An uncertainty factor for decision makers is the abundance of offered technologies and they often lack sufficient information to make their choice. Additionally, there are several concerns regarding LED technologies.
What were the trends in ISL as highlighted by the conference?
An increasing number of municipalities are now replacing their old fashioned and inefficient street lighting by LED street lighting systems.
The trend is going towards implementing so called “smart or intelligent lighting systems”, providing the respective quantity of energy needed at the particular time and location.
What were the conclusions of the conference?
From the practical point of view, the conclusion is that a lack of knowledge and experience in the modernization of street lighting systems constitutes a barrier for many municipalities and communal energy suppliers. To overcome existing restraints, it is important to involve both groups of actors - the municipalities and the utilities - in the project planning process for future innovative projects on street lighting.

European local authorities for intelligent public lighting: success of the ESOLi conference at Light+Building Frankfurt!
On Tuesday 17 April 2012 a full room of participants listened with interest to the presentations about energy saving public lighting projects all over Europe. The ESOLi conference, supported by the Association of Municipalities of the FrankfurtRhineMain Region, attracted local authorities from several European countries.
As Sabine Piller (Berlin Energy Agency) explained, the ESOLi project - co-funded by the Intelligent Energy Europe programme of the EU - aims at underpinning the diffusion of the energy saving technologies in the field of intelligent public lighting in Europe. The advantages of these “intelligent” technologies are numerous, of which the most important are that they lead to remarkable energy saving with a consequent reduction of CO2 emissions, electricity and maintenance costs. Besides, these installations can open the way towards a “smart city” and a sustainable urban future.
The speakers talked about the advantages and the environmental and economic benefits of adaptive lighting with intelligent control, illustrating in detail the lessons learnt in Oslo (Norway), Düsseldorf (Germany), Ljubljana (Slovenia), Göttingen (Germany) and Gothenburg (Sweden).
The Municipality of Oslo presented their experience which began over ten years ago, when a centrally controlled adaptive road lighting system, based on two-way wireless and e-communication, was introduced. The 10.000 intelligent light points lead to 70% lower energy consumption. The long-term goal of the Municipality of Oslo is to implement this dynamic street lighting system in all the new installations of the city. Another Scandinavian example from Gothenburg showed similar success: 60% less energy costs and a more environment-friendly city, thanks to the 2500 intelligent light points installed. The project, realized with the contribution of the Climate Investment (KLIMP) won the acknowledgement of the Swedish Environmental Protection Agency as best practice example to be followed.
Then it was turn of the municipalities of Düsseldorf and Göttingen to illustrate their successful examples: the installation of a traffic controlled street lighting system along the airport feeder road, and a sensor controlled public lighting system in a residential area, respectively. A Southern European example was presented by Ljubljana, which with its 4000 intelligent light points registered energy savings up to 58%.
After the presentation of these encouraging experiences, the participants could learn interesting information about the LUCI network (Lighting Urban Community International) which is an international forum of cities for learning and exchanging knowledge about urban lighting strategies and for promoting successful initiatives and best practices of cities around the world.
As a conclusion, a fact worth meditating on: if all public authorities in Europe switched to “intelligent” systems, like adaptive street lighting and intelligent control, Europe could gain more than 60% of energy savings!

ESOLi: paving the way for outdoor intelligent lighting systems
The ESOLi (Energy Saving Outdoor Lighting) project, supported by the Intelligent Energy - Europe program of the European Union, has just completed its first year of activities.
The ESOLi consortium consists of 16 organizations from 14 European countries representing street lighting operators, energy agencies, local authorities, key actors, industry representatives and consultants. It plans to assess energy savings in different settings, help coordinate procurement initiatives, speed up the development of legislation and standards, and draw up a list of customers' requirements in order to foster the extended use of intelligent lighting systems in outdoor areas and remove barriers for a large scale technology roll-out.
This year, project partners will organize workshops in 14 countries followed by advanced training seminars for lighting professionals.
LUCI member, the City of Gothenburg, one of the project partners, will be the host of the mid-term project meeting in May 2011 to discuss the results so far.

ESOLi: Energy consulting for municipalities
- EU-project ESOLi designed to support municipalities with energy saving
- Reduction of energy consumption of about 38 TWh/a is possible
Berlin, 7th June 2010
There are 80 million street lights across Europe. Nowadays energy consumption for street lighting in Europe is about 60 terawatt hours (TWh) per year. According to the European project “E-street” 63.7 % or 38 TWh of the European energy consumption in outdoor lighting could be saved by switching to intelligent systems like adaptive street lighting and the use of LEDs (Light-emitting-diodes). Seeing that energy demand causes high costs for municipalities the new program Energy Saving Outdoor Lighting (ESOLi) offers advice to municipalities on specific issues and support by seminars, a best practice catalogue, a benchmarking tool for end-users and case studies.
To overcome concerns about the performance and reliability of new technologies, financial obstacles and lacks of information the European Commission launched ESOLi in the framework of the Intelligent Energy Europe program. The Berlin Energy Agency Ltd as responsible project coordinator and 15 project partners out of 14 countries constitute the consortium of ESOLi. The program’s specific goals are: transfer of knowledge, establishment of a comprehensive network of key actors in the field and development of innovative financing schemes.
Information for key actors in municipalities like a market research and best practices are to be presented on the upcoming project website www.esoli.org in the course of the next months. In addition the website offers advice to municipalities on specific issues, calculation tools and contact details for further information.
