  Title Responses of insectivorous bats and nocturnal insects to local changes in street light technology Type Journal Article
  Year 2019 Publication Austral Ecology Abbreviated Journal  
  Volume 44 Issue 6 Pages 1052-1064  
  Keywords Animals; Mammals; Bats; Chalinolobus gouldii; Miniopterus schreibersii oceanensis; Australia; LED; lighting; street lighting  
  Abstract Artificial light at night is a pervasive anthropogenic stressor for biodiversity. Many fast‐flying insectivorous bat species feed on insects that are attracted to light‐emitting ultraviolet radiation (10–400 nm). Several countries are currently focused on replacing mercury vapour lamps, which emit ultraviolet light, with more cost‐efficient light‐emitting diode (LED) lights, which emit less ultraviolet radiation. This reduction in ultraviolet light may cause declines in insect densities in cities, predatory fast‐flying bats, and some edge‐foraging and slow‐flying bats. Capitalising on a scheme to update streetlights from high ultraviolet mercury vapour to low ultraviolet LED in Sydney, Australia, we measured the activity of individual bat species, the activity of different functional groups and the bat and insect communities, before and after the change in technology. We also surveyed sites with already LED lights, sites with mercury vapour lights and unlit bushland remnants. Species adapted to foraging in cluttered vegetation, and some edge‐space foraging species, were more active in unlit bushland sites than in all lit sites and decreased in activity at lit sites after the change to LED lights. The change to LED streetlights caused a decrease in the fast‐flying Chalinolobus gouldii but not Miniopterus schreibersii oceanensis, the latter being more influenced by seasonal and environmental variables. Insect biomass was not affected by changing light types, but instead was negatively correlated with the moon's percentage illuminance. Changing streetlights to LEDs could result in a decline in some insectivorous bats in cities. This study confirms that unlit urban bushland remnants are important refuges for high bat diversity, particularly for more clutter‐adapted species and some edge‐space foraging species. Preventing light penetration into unlit bushland patches and corridors remains essential to protect the urban bat community.

  Title Economic feasibility of energy efficiency improvements in street lighting systems in Rome Type Journal Article
  Year 2017 Publication International Journal of Energy Economics and Policy Abbreviated Journal  
  Volume 7 Issue 1 Pages 190-198  
  Keywords Economics; Energy; Society; LED lighting; LED; real options  
  Abstract This study evaluates an investment project concerning the redevelopment of the public lighting of the Municipality of Rome. In particular, we consider the replacing of the traditional lamps of the system with LED lamps. We consider the factors that affect this kind of project: the cost of energy, the manteinance cost, the investment cost and the Weighted Average Cost of Capital (WACC). Our results underline the reduction of energy consumption and of the maintenance costs, lower emissions of CO2 into the atmosphere, the reduction of light pollution, the positive effects on road safety and the indipendence by incentives.

  Title Lighting and Power Upgrade Recommendations for U.S. National Park Service Caribbean Units Type Journal Article
  Year 2019 Publication National Park Service Caribbean Units Abbreviated Journal  
  Volume Issue Pages  
  Keywords Lighting; Conservation; Ecology; Skyglow; Planning  
  Abstract The U.S. National Park Service (NPS) maintains and operates numerous park units along the Eastern Seaboard of the United States, extending into the Caribbean to Commonwealth territories like Puerto Rico and the U.S. Virgin Islands (USVI). Several of these units were in the direct path of hurricanes Irma and Maria during the 2017 hurricane season and suffered considerable damage, including power outages, structural damage, and destroyed equipment. In February 2018, a task force deployed to three locations in the Caribbean to assess hurricane damage to the existing lighting systems and energy infrastructure. The primary objective was providing related recommendations for resiliency upgrades to the lighting and electrical supply systems, with special added emphasis on the numerous goals, objectives, and requirements of the NPS (such as protecting night skies, wildlife, wilderness character, cultural resources, etc.). Numerous opportunities exist for simultaneously increasing resiliency and preserving natural environments within these sensitive locations, and technological approaches that work in the extreme conditions encountered here should readily translate to many other less complex sites across the greater park system. Ultimately, care and attention to detail in implementation are the most important underlying requirements for success across the myriad needs likely encountered at these sites, once commitment to resolving them has been secured

  Title A decision support system for assessment of street lighting tenders based on energy performance indicators and environmental criteria: Overview, methodology and case study Type Journal Article
  Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 51 Issue Pages 101759  
  Keywords Lighting; Policy  
  Abstract While LEDs are now the most efficient light sources, their adoption in the road lighting design has been delayed due to a variety of reasons such as malpractice, huge number of inappropriate luminaires, missing technical information and ineffective policies. An example is the, low luminous efficacy values, which confuse the decision makers for national roads. The new part of EN13201-5 describes many energy performance indicators, which are still not used in street light projects or in lighting simulation tools. The aim of this paper is a) to present the significance of using these indicators through a decision tool, capable to evaluate a number of lighting designs in a lighting tender and b) to propose an evaluation method as part of a future energy policy including environmental criteria. A case study is also presented. The results show that the aforementioned decision tool is necessary in order to evaluate the ranking of the corresponding offers. Thus, increased energy savings could be achieved together with environmental benefits. In the case examined, the best solution resulted in 72.1% energy savings and CO2 emission reduction.

  Title Lighting of urban green areas – the case of Grabiszyn Park in Wrocław. Searching for the balance between light and darkness through social and technical issues Type Journal Article
  Year 2019 Publication E3S Web of Conferences Abbreviated Journal E3S Web Conf.  
  Volume 100 Issue Pages 00049  
  Keywords Society; Lighting  
  Abstract Illuminating the urban green spaces could lead to conflicts of spatial, technical and social nature. This relatively new, though already global, problem is expected to grow bigger with the further increase of urban areas artificial brightness. The case of Grabiszyn Park in Wrocław is an example of how difficult it is to find a balance between big-city lights and a natural darkness. The situation is even more difficult if the light is not legally recognized as a significant source of air pollution and direct nuisance at the legal level. The aim of the paper is to recognize the broader perspective of urban greenery lighting issues, global recommendations basis and the local awareness. The authors also made an attempt to analyze and assess the project implementation, as well as to characterize the components of the quality of an urban green areas lighting.
