Title Experimental Study of the Levels of Street Lighting Using Aerial Imagery and Energy Efficiency Calculation Type Journal Article
Year 2018 Publication (down) Sustainability Abbreviated Journal Sustainability
Volume 10 Issue 12 Pages 4365
Keywords Remote Sensing; Lighting
Abstract This article describes an innovative method for measuring lighting levels and other lighting parameters through the use of aerial imagery of towns and cities. Combined with electricity consumption data from smart electricity meters, it was possible to measure the energy efficiency of public lighting installations. The results of this study also confirmed that lighting measurements, installation material, luminaire position, and electricity consumption data can be easily integrated into geographic information systems (GIS). The main advantage of this new methodology is that it provides information about lighting installations in large areas in less time than more conventional procedures. It is thus a more effective way of obtaining the data required to calculate the energy efficiency of lighting levels and electricity consumption. There is even the possibility of generating street lighting maps that provide local administrations with up-to-date information regarding the status of public lighting installations in their city. In this way, modifications or improvements can be made to achieve greater energy savings and, if necessary, to correct the distribution or configuration of public lighting systems to make them more efficient and sustainable. This research studied levels of street lighting and calculated the energy efficiency in various streets of Deifontes (Granada), through the use of aerial imagery.

Title The LED Paradox: How Light Pollution Challenges Experts to Reconsider Sustainable Lighting Type Journal Article
Year 2019 Publication (down) Sustainability Abbreviated Journal Sustainability
Volume 11 Issue 21 Pages 6160
Keywords Energy; Lighting; Society
Abstract In the 21st century, the notion of “sustainable lighting” is closely associated with LED technology. In the past ten years, municipalities and private light users worldwide have installed light-emitting diodes in urban spaces and public streets to save energy. Yet an increasing body of interdisciplinary research suggests that supposedly sustainable LED installations are in fact unsustainable, because they increase light pollution. Paradoxically, blue-rich cool-white LED lighting, which is the most energy-efficient, also appears to be the most ecologically unfriendly. Biologists, physicians and ecologists warn that blue-rich LED light disturbs the circadian day-and-night rhythm of living organisms, including humans, with potential negative health effects on individual species and whole ecosystems. Can the paradox be solved? This paper explores this question based on our transdisciplinary research project Light Pollution—A Global Discussion. It reveals how light pollution experts and lighting professionals see the challenges and potential of LED lighting from their different viewpoints. This expert feedback shows that “sustainable LED lighting” goes far beyond energy efficiency as it raises complex design issues that imply stakeholder negotiation. It also suggests that the LED paradox may be solved in context, but hardly in principle.

Title A Multi-Criteria Assessment Procedure for Outdoor Lighting at the Design Stage Type Journal Article
Year 2020 Publication (down) Sustainability Abbreviated Journal Sustainability
Volume 12 Issue 4 Pages 1330
Keywords Lighting
Abstract This paper presents an attempt at a unified approach for the assessment of outdoor lighting solutions at the design stage. First of all, the lighting criteria for different types of outdoor lighting installations have been carefully described. Despite the differences in criteria, it is possible to find a common ground for the assessment of lighting solutions at the design stage. This is based on the need for the assessment of lighting solutions to be included in the requirements for the luminous environment, light pollution, and energy efficiency. The review and analysis of the standards and reports allows an experimental procedure to be created, the main aim of which is to find the best and most sustainable lighting solution for any outdoor situation. The procedure was tested by the example of an analysis of parking lot lighting solutions. In the case analyzed, 120 solutions were considered. It appeared that, in only 65 cases were the requirements referring to both lighting condition and light pollution met. Finally, based on the lighting energy efficiency assessment, ten solutions were selected as the most suitable. Furthermore, only one solution out of the ten was the most beneficial, taking into account the extra criterion of basic economic cost. The case study confirms that the assessment procedure allows the most beneficial solution to be selected, taking into account the luminous environment, as well as light pollution and energy efficiency criteria. The proposed multi-criteria assessment procedure may be used as a valuable tool by lighting designers to select the most beneficial solution in order to meet the needs of safety, visual efficiency, and comfort, as well as taking into account light pollution and energy efficiency restrictions.

Title Public street lighting service standard assessment and achievement Type Journal Article
Year 2015 Publication (down) Socio-Economic Planning Sciences Abbreviated Journal Socio-Economic Planning Sciences
Volume 53 Issue Pages 14-22
Keywords Lighting
Abstract Nighttime lighting is an important public service that impacts human activities and promotes transportation and pedestrian safety. Of course, such services are not free and have been found to have negative impacts on the environment. Responsible stewardship of the built environment requires that efficiency and care in the delivery of services be taken, particularly in the context of sustainability concerns. A significant problem with existing urban infrastructure systems like street lighting is that they have evolved over time using rule-of-thumb planning standards. Given this, systematic assessment and re-evaluation offers much potential for enhancing the spatial efficiency of infrastructure but also the opportunity to explicitly account for environmental impacts in combination with safety and security. This paper applies a methodology for studying lighting in urban areas based upon the use of spatial analytics, including GIS and spatial optimization. Findings and results are reported for a study area in San Diego, California, highlighting current system configuration issues, method development and the potential long term benefits of systematic analysis of public sector services.

Title Changing the colour of night on urban streets – LED vs. part-night lighting system Type Journal Article
Year 2019 Publication (down) Socio-Economic Planning Sciences Abbreviated Journal Socio-Economic Planning Sciences
Volume in press Issue Pages 100692
Keywords Energy; Planning; Economics; United Kingdom; LED; Lighting
Abstract Many cities in the United Kingdom are upgrading the streetlights to white light-emitting diode (LED) lamps for reducing the electricity costs and attaining the sustainable energy solutions. Installation of LED lamps on urban street requires higher installation costs and a long-term period to payback benefits of replacing outdated streetlights in terms of energy savings and costs. To achieve the short-term energy efficiency of urban street lighting, city councils sometimes adopt the part-night lighting system particularly in the residential areas. The Coventry City Council recently replaced 29,701 existing sodium lights with LED lamps. This paper performs the economic analyses to understand the feasibility of two street lighting systems: LED lamps and ‘part-night’ lightings on the Coventry streets during the twenty-year period assuming the return period of investment is twenty years. The projection of energy consumption and costs for LED lamps and part-night lighting systems shows that electricity can be saved by 44% and 21% comparing to current electricity usages, respectively. Considering the budgetary constraints of Coventry City Council, this paper concludes that the part-night lighting system may be beneficial in short-term period, but it is economically feasible to replace the existing lower efficiency lights with LED lamps.
