  Title Gazing Up: An Exploration of Municipal Night Lighting Practices Amongst Six Canadian Municipalities Type Manuscript
  Year 2014 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords light pollution; public policy; Canada; outdoor lighting; municipal  
  Abstract Light pollution is broadly defined as the unnecessary illumination of the nocturnal environment. Light pollution is a pervasive phenomena shown to have harmful consequences for both the biotic and abiotic components of an ecosystem. While some municipalities have begun to address the environmental and economic costs of light pollution, most have not. The goal of this study was to investigate current municipal night lighting practices for six selected Canadian municipalities with the aim of determining their policies and practices for night lighting. Semi-structured interviews with key informants were conducted and analyzed using a mixed methods approach that included a thorough literature review. The results indicate that rising energy costs, aging infrastructure and the lighting industry are driving the majority of changes taking place in adapting municipalities while most municipalities remain content with status quo. The research conducted led to guideline improvements for municipal night lighting in today’s municipalities.

  Title Observing other pedestrians: Investigating the typical distance and duration of fixation Type Journal Article
  Year 2014 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technologying Res & Tech  
  Volume 47 Issue 5 Pages 548-564  
  Keywords traffic safety; pedestrians; roadway lighting; visibility; light at night  
  Abstract After dark, road lighting should enhance the visual component of pedestrians’ interpersonal judgements such as evaluating the intent of others. Investigation of lighting effects requires better understanding of the nature of this task as expressed by the typical distance at which the judgement is made (and hence visual size) and the duration of observation, which in past studies have been arbitrary. Better understanding will help with interpretation of the significance of lighting characteristics such as illuminance and light spectrum. Conclusions of comfort distance in past studies are not consistent and hence this article presents new data determined using eye-tracking. We propose that further work on interpersonal judgements should examine the effects of lighting at a distance of 15 m with an observation duration of 500 ms.

  Title A study of atmosphere perceptions in a living room Type Journal Article
  Year 2014 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology  
  Volume 47 Issue 5 Pages 581-594  
  Keywords lighting; indoor lighting; perception; Chinese; Dutch; aesthetics  
  Abstract An experiment has been carried out to investigate the effect of lighting on the perception of atmosphere in a living room, using three types of light sources: halogen, fluorescent and LED lamps. In a psychophysical experiment, 29 native Chinese observers assessed eight lighting conditions having different luminances and correlated colour temperatures. For each condition, 71 scales were employed using the categorical judgment method. Factor analysis identified two underlying dimensions: liveliness and cosiness. This agrees with those found by Vogels who used Dutch observers to assess atmosphere perception. Both observer groups also agreed that an increase of luminance would make the room more lively. However, there were also some disagreements such as a higher CCT source would make the room more lively for Chinese observers but less lively for Dutch observers.

  Title Demographic effects of artificial nighttime lighting on animal populations Type Book Chapter
  Year 2014 Publication Environmental Reviews Abbreviated Journal Environ. Rev.  
  Volume 22 Issue 4 Pages 323-330  
  Keywords diurnal; lighting; night; nocturnal; light pollution; light at night; Photoperiodism; demography; demographics; population dynamics  
  Abstract Artificial lighting, especially but not exclusively through street lights, has transformed the nighttime environment in much of the world. Impacts have been identified across multiple levels of biological organization and process. The influences, however, on population dynamics, particularly through the combined effects on the key demographic rates (immigration, births, deaths, emigration) that determine where individual species occur and in what numbers, have not previously been well characterized. The majority of attention explicitly on demographic parameters to date has been placed on the attraction of organisms to lights, and thus effectively local immigration, the large numbers of individuals that can be involved, and then to some extent the mortality that can often result. Some of the most important influences of nighttime lighting, however, are likely more subtle and less immediately apparent to the human observer. Particularly significant are effects of nighttime lighting on demography that act through (i) circadian clocks and photoperiodism and thence on birth rates; (ii) time partitioning and thence on death rates; and (iii) immigration/emigration through constraining the movements of individuals amongst habitat networks, especially as a consequence of continuously lit linear features such as roads and footpaths. Good model organisms are required to enable the relative consequences of such effects to be effectively determined, and a wider consideration of the effects of artificial light at night is needed in demographic studies across a range of species.

  Title Solid state lighting review – Potential and challenges in Europe Type Book Chapter
  Year 2014 Publication Renewable and Sustainable Energy Reviews Abbreviated Journal Renewable and Sustainable Energy Reviews  
  Volume 34 Issue Pages 30-48  
  Keywords Lighting; solid-state lighting; LED; lighting technology; review; Europe  
  Abstract According to IEA estimates, about 19% of the electricity used in the world is for lighting loads with a slightly smaller fraction used in the European Union (14%). Lighting was the first service offered by electric utilities and still continues to be one of the largest electrical end-uses. Most current lighting technologies can be vastly improved, and therefore lighting loads present a huge potential for electricity savings.

Solid State Lighting (SSL) is amongst the most energy-efficient and environmentally friendly lighting technology. SSL has already reached a high efficiency level (over 276 lm/W) at ever-decreasing costs. Additionally the lifetime of LED lamps is several times longer than discharge lamps. This paper presents an overview of the state of the art SSL technology trends.

SSL technology is evolving fast, which can bring many advantages to the lighting marketplace. However, there are still some market barriers that are hindering the high cost-effective potential of energy-efficient lighting from being achieved. This paper presents several strategies and recommendations in order to overcome existing barriers and promote a faster penetration of SSL. The estimated savings potential through the application of SSL lighting systems in the European Union (EU) is around 209 TWh, which translates into 77 million tonnes of CO2. The economic benefits translate into the equivalent annual electrical output of about 26 large power plants (1000 MW electric). Similar impacts, in terms of percentage savings, can be expected in other parts of the World.
