  Title Energy Efficiency Considerations for LED-based Lighting of Multipurpose Outdoor Environments Type Journal Article
  Year 2015 Publication IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensingournal of Emerging and Selected Topics in Power Electronics Abbreviated Journal IEEE J. Emerging and Sel. Topics in Power Elec.  
  Volume PP Issue 99 Pages 1  
  Keywords Lighting; LED lighting; LED; optimization; lighting technology; lighting design; energy; energy efficiency  
  Abstract Nowadays street lighting accounts for 53% of outdoor lighting use and the market is continuously increasing. In the context of rising energy prices and growing environmental awareness, energy efficiency is becoming one of the most important criteria for street lighting systems design. LED-based lights have become the primary option for replacing conventional light bulbs, being digitally controllable, small, highly efficient, and cheap to manufacture. Advanced control strategies adapted to ambient conditions are needed to combine low energy consumption and high quality light ambience according to changing specifications. This paper describes an outdoor lighting solution aimed at energy efficient performance in the context of multipurpose outdoor environments, where control is crucial in achieving efficiency improvements. The work addresses efficiency at the component level, by optimizing the performance of LED drivers, and at system level, defining the control strategy and associated hardware infrastructure. The approach designed was tested in a real environment. The performance of the lighting installation was assessed using the web-based monitoring application, providing real-time consumption information and aggregated historical data.

  Title Light Pollution Index (LPI): An Integrated Approach to Study Light Pollution with Street Lighting and Façade Lighting Type Journal Article
  Year 2012 Publication The Journal of the Illuminating Engineering Society Abbreviated Journal  
  Volume 9 Issue 2 Pages 127-145  
  Keywords Planning; Lighting  
  Abstract Rather than being complementary, street lighting and façade lighting are typically designed independently of each other. As a result, light from street lighting luminaires might spill onto building façades and influence characteristics of the façade lighting including required light levels and color. Conversely, façade lighting might reflect onto the street and contribute to the street illumination. This manuscript presents an integrated approach to analyzing the interaction between the street and façade lighting in consideration of light pollution control. A generic street model with various calculation grids was studied. It was found that a moderately lit façade contributes to a horizontal illuminance of 5 lux or more on the street and a vertical illuminance of 4 lux or more 1.5 m above the sidewalk. An over-illuminated street may result when both street and façade lighting exist without reference to each other. The size of the light-pollution calculation grid and the use of a 3-D illuminance graph were studied. It was found that fluctuations in the calculated amount of light pollution could occur unless the size of the pollution calculation grid is large enough to capture all of the upward flux. A method of achieving the optimal size of the calculation grid is demonstrated. Shortcomings of using light pollution percentage as a light pollution index are highlighted and an alternative light pollution index is proposed.

  Title Sustainable outdoor lighting for reducing energy and light waste Type Conference Article
  Year 2016 Publication 9th International Conference Improving Energy Efficiency in Commercial Buildings and Smart Communities Abbreviated Journal  
  Volume Issue Pages 202-213  
  Keywords lighting design; lighting technology; light pollution  
  Abstract The lack of lighting planning for internal and external illumination of buildings contributes to wasting energy and to the issue of light pollution. This will be demonstrated with research from the ground and by analysis of images, taken with detectors on satellites, the International Space Station or planes. Besides large area floodlighting from airports or sports facilities, facade illumination is the most important contributor. The effects of malpractice versus sustainable lighting planning solutions will be demonstrated with some examples in cities like Bonn, Strasbourg, Athens and Thessaloniki. Further examples in the countryside will demonstrate lighting practice in the German star park Biosphere Reserve Rhön. Facade lighting planning, considering optimal alignment, the intensity and the colour quality of the illumination, will contribute to reducing light pollution and thus waste of energy and will increase human comfort at the same time.

Experience shows that unilateral promoting energy efficiency will finally result in more extended use of energy, which is known as rebound effect. In addition the small size and long lifetime of the modern solid state lighting will result in an increased use even in remote places thereby emitting more artificial light into the natural night. This does not only affect the energy use, but also the biological rhythms of animals and human beings.

More interdisciplinary criteria for a sustainable lighting with reduced light pollution will be discussed based on the observations including data provided by the EU-network “Loss of the Night”-Network (EU-COST Action ES1204 LoNNe).

  Title Sky glow and outdoor lighting trends since 1976 at the Lowell Observatory Type Journal Article
  Year 1990 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal PASP  
  Volume 102 Issue Pages 481  
  Keywords Skyglow; Lighting  
  Abstract Urban sky-glow (light pollution) trends, recorded photoelectrically in intermediate-band b (472 nm) and y (551 nm) filters at the original site of the Lowell Observatory on Mars Hill near downtown Flagstaff, Arizona, reflect not just the population growth of the surrounding city but also some ameliorating effects of lighting controls and a changing mix of outdoor lighting sources. Since 1976 the sky brightness increased in b but has been virtually constant in y. New ordinances limit lighting growth near observatories and require monochromatic low-pressure sodium luminaires for most applications.
