Connected Solar Lighting : a reliable response to the sustainable development, savings and aesthetics challenges of our times

Edouard Warnier, Global Solar Lighting Business Manager at Schréder

Solar lighting can be the reliable answer to the main concerns of cities regarding energy bills, the beauty of public spaces, and reaching their sustainable development targets. Solar lighting also comes with intelligence, allowing cities to become smarter, with solar poles sending a strong signal from elected officials to citizens.

Istanbul, with its rich culture, is as intriguing and historically significant as it is energetic and contemporary. Located on two continents, Istanbul has been the capital of two strong empires for sixteen centuries, Eastern Roman and Ottoman. Its cultures and traditions blend East and West, Mediterranean and Anatolian. 

The city’s growth was primarily fueled by the building of electricity infrastructure, which promoted industrialization and urbanization. Today, Istanbul is one of the world’s megacities, with a population of 20 million. Istanbul is a crossroads of ideas, with a multicultural touch and a vibrant environment anchored in humanity’s past while looking forward.

Green Istanbul, founded in 2019, takes the responsibility and challenges to operate the metropolis through an innovative approach to municipal governance that seeks to develop city infrastructure by recovering tradition while envisioning a sustainable future.

The feeling of safety in urban spaces – Children’s and young people’s perspective

The impact of urban lighting is significant on us – it either supports our dark time activities or it makes them difficult and unsafe. Helsinki emphasizes the urgent need to solve problems that children and young people have in the dark periods of the day and the year. The improvement of lighting is one tool in creating safer and more secure environment for all ages, but specially for the inhabitants under 18. A certain small square in the urban renewal area in the east of Helsinki is most often described as “horrifying”, or “better always to avoid passing through”. At the edge of this problematic square there is the popular local youth center and a library. Our project develops the means to listen to the true experts of this neighborhood – the young and the local actors – and based on this knowledge build better urban lighting. This project is part of a pilot that begun in March 2024. With the name of this project district is Kontula, translatable as “Home” or “Homestead”, we aim to improve the surrounding so that it would better match its name!

The Partnerships of Safe and Sustainable Darkness

Henrika Pihlajaniemi, Associate Professor at University of Oulu

For decades, the development of lighting has meant increasing the amount of light. As a result, over-lighting in urban areas has become a global problem. However, the observed adverse effects of over-lighting on the well-being of people and nature, as well as the growing energy consumption, are turning the focus in planning urban environments from the quantity of light to the quality of light. Targeted quality features in the design include, for example, the harmonious matching of light shades and intensities to the environment, and the ability to adjust the light according to the need for use. The goal is not to reduce the amount of lighting everywhere, but to find an ecologically, socially and economically sustainable balance between light and darkness. Today’s technology provides many opportunities for measuring and regulating lighting, but it is also important to increase understanding of how people experience and value different lighting conditions in urban space. Then the amount of light can be reduced and still maintain a positive and safe experience of the environment. By adjusting lighting levels, for example, more space can be created for architectural and experiential lighting, which have been found to support the experience of a safe and comfortable city.

The presentation showcases two European Regional Development Fund projects where the University of Oulu has collaborated with the City of Oulu to research and develop ways to create good and safe experiences of darkness in various urban environments, supporting the well-being of people and nature. In the projects, evaluated models of co-design, implementation and partnerships of urban lighting and urban darkness are created. The projects study methods to evaluate plans and dark-time urban environments from the perspectives of environmental quality, users’ experiences, and sustainability. The multidisciplinary composition of the research group brings perspectives and methods from architecture, lighting design, art, humanities, as well as industrial engineering and management into the implementation of the research.
