Title Optimization of Urban Street Lighting Conditions Focusing On Energy Saving, Safety and Users’ Needs Type Journal Article
Year 2018 Publication Contemporary Urban Affairs Abbreviated Journal
Volume 2 Issue 3 Pages 112-121
Keywords (up) Lighting; Economics; Planning
Abstract The outdoor lighting constitutes a significant part of the night activities of people in contemporary cities. Nevertheless, in many cases, this may result in the increasing and irrational use of it affecting the users of public areas, the environment and driving safety. The subject of this paper is to extend the discussion on the subject, to provide answers and to suggest methods for the improvement of the existing conditions in urban street lighting through the use of new technologies and smart lighting management systems, with the aim of achieving a smooth relationship between the user’s needs, safety, sustainability, quality of life and energy saving.

Title LEDs for photons, physiology and food Type Journal Article
Year 2018 Publication Nature Abbreviated Journal Nature
Volume 563 Issue 7732 Pages 493-500
Keywords (up) Lighting; Human Health; Plants; Review
Abstract Lighting based on light-emitting diodes (LEDs) not only is more energy efficient than traditional lighting, but also enables improved performance and control. The colour, intensity and distribution of light can now be controlled with unprecedented precision, enabling light to be used both as a signal for specific physiological responses in humans and plants, and as an efficient fuel for fresh food production. Here we show how a broad and improved understanding of the physiological responses to light will facilitate greater energy savings and provide health and productivity benefits that have not previously been associated with lighting.

Title An investigation into the risk of night light pollution in a glazed office building: The effect of shading solutions Type Journal Article
Year 2018 Publication Building and Environment Abbreviated Journal Building and Environment
Volume 145 Issue Pages 243-259
Keywords (up) Lighting; Planning
Abstract Light pollution has been recognised as a major environmental problem in urban areas at night. This study presents an investigation into the impact of seven various shading solutions on the risk of light pollution caused by indoor artificial lighting in a fully glazed office building. Radiance, a ray-tracing package, was adopted to calculate external illuminances produced by indoor lighting applications at various positions. It has been determined that: 1) A glazed façade could become a critical source of light pollution or obtrusive light (sky glow and light trespass) due to applications of indoor lighting at night; 2) A light shelf could perform well on the protection of both light trespass and sky glow; 3) A large overhang and horizontal louvre could effectively lower the risk of light trespass, but would possibly cause the deterioration of sky glow; and 4) No significant impact of short overhang and vertical louvre can be found on the two aspects of light pollution. This study exposes a significant implication; apart from their principal functions, the shading devices applied in a largely glazed building may require a new role in controlling obtrusive light in cities at night.

Title A Novel Illuminance Control Strategy for Roadway Lighting Based on Greenshields Macroscopic Traffic Model Type Journal Article
Year 2018 Publication IEEE Photonics Journal Abbreviated Journal IEEE Photonics J.
Volume 10 Issue 1 Pages 1-11
Keywords (up) Lighting; Planning; Economics
Abstract Most street lights currently deployed have constant illumination levels or vary

based on a predetermined schedule. However, with advances in lighting controls, intelligent transportation systems, and the efforts of transportation agencies at regional and national levels to better sustain and manage the transportation system by monitoring the roadway network, many different types of real-time traffic data are available; which enables the implementation of a traffic responsive outdoor light system. The International Commission on Illumination (CIE) has proposed a class-based lighting control model based on a number of roadway parameters, some of which are traffic related. However, the adaptation of the available traffic data to the existing model is not obvious. In addition, the CIE model can be improved to better reflect traffic characteristics to increase energy efficiency of the overall street lighting system. The intention of this research is to quantify the relationship between real-time traffic, and roadway lighting and to develop a control strategy based on real-time traffic data in order to reduce light energy consumption, enhance safety, and maximize throughput of the roadway. Significant energy savings were observed when the proposed control strategy was implemented in two case studies using available lighting and traffic data for Washington, DC, and Montgomery County, MD, representing urban and rural roadway networks, respectively.
