Abstract |
Outdoor lighting offers many benefits to its users and is often considered a necessity for an active lifestyle when living in modern society. Sustainable outdoor lighting should fulfil the functional needs of the users, be cost- and energy-efficient, and result in minimal environmental impact. So far, a limited number of studies have been able to present clear strategies on how to plan and use outdoor lighting to ensure that it contributes towards sustainable development. Therefore, this study aimed to answer the following questions: (1) How many of the previously established sustainability indicators are already used by municipalities in their lighting planning? (2) Which types of indicators are not used by municipalities? Another aim of the study was to further develop the framework of sustainability indicators by adding new indicators that were identified from lighting plans of Swedish municipalities and the existing literature. In this study, lighting master plans from 16 randomly chosen Swedish municipalities with varying population sizes were analyzed. The results show that few sustainable indicators are used by the municipalities’ lighting plans, especially in the social dimension. The existing framework of sustainability indicators was developed by adding new indicators. Furthermore, 28 new indicators were identified, eight originated from new studies and the literature, and 20 originated from the municipalities’ lighting master plans. This study shows that there is a need for guidelines and recommendations for working with outdoor lighting from a sustainability perspective, especially in the social dimension of sustainability, where most of the new indicators were identified. |

Abstract |
Urbanization continues to provide habitat for more and more of the planet’s human population. Accompanying this process are the energy, transport, and service infrastructures that support urban life. Enmeshed in these networks is artificial illumination and its unintended consequences. Light pollution, for instance, accounts for a growing global carbon footprint, yet more efficient artificial lighting methods using LEDs have resulted in increasingly higher levels of brightness at night. This is altering natural cycles of light and dark, directly impacting on the circadian rhythms of our bodies and having disastrous effects upon other species and their ecosystems. This issue of critical importance has been referred to by some scientists as a hidden global challenge but the public awareness and understanding of it is negligible. Where is design in addressing such poor performance? The growing problem of how we perceive darkness and the attempts to manage it, typically through artificial illumination, requires new design strategies to create viable alternatives to current pathways. How can we advocate for the “nocturnal commons” when the majority of society does not even know what is disappearing or understand the implications? This article proposes the concept of “Dark Design” to set out a new framework for advocacy and creativity to raise awareness of these complex issues and address them. By bringing together a diverse range of approaches, “Dark Design” seeks to establish a field for emerging principles and practices to design with darkness rather than against it. In doing so, it calls for the important and urgent need for design to commit, act and engage others in the future of our planet, its people, and non-human species. |

Abstract |
If excessive and misdirected, street lighting (SL) causes energy waste and might pose significant risks to humans and natural ecosystems. Based on data collected by an interactive user-oriented method, we developed a novel empirical approach that enables the spatial identification of over-illuminated areas in residential neighborhoods and calculation of potential energy savings that can be achieved there, by reducing excessive illumination. We applied the estimated model to a densely populated residential neighborhood in the City of Tel Aviv-Yafo in Israel, to test the proposed approach’s performance. According to our estimates, illumination levels can be lowered by up to 50% in approximately 60% of the neighborhood’s area, which is currently over-illuminated, thus leading to significant energy savings, while preserving a reasonable level of visual comfort associated with SL. |
