Title Epilogue. Field notes from the end of the world: Light, darkness, Energy, and endscape in polar night Type Journal Article
Year 2019 Publication Journal of Energy History Abbreviated Journal (up)
Volume 2 Issue Pages
Keywords Darkness; Lighting; Society; Psychology
Abstract This personal essay describes light(s) and darkness(es) in Longyearbyen, Svalbard (Norway) during polar night in January 2019. Drawing on autoethnographic methods, I also seek to describe how I experienced the remarkable lightscapes and darkscapes of the far north during winter. I suggest how the history of energy in Longyearbyen has both shaped and been shaped by the “extreme” light/dark cycle of the high Arctic. In the process, I develop the concept of “endscape” to characterize vestiges of a landscape that has been, and will continue to be, transformed by global climate change, and will eventually disappear. This recent experience illustrates the potential of experiential, reflexive ways of contending with light/dark. It also draws attention to tensions in the academic study of light/dark and the history of energy, and how they play out in practice, in the context of a conference held in a remote location that requires scholars to contribute to the continued extraction of fossil fuels –something that most would otherwise decry. I suggest that Longyearbyen is a useful case study for other endscapes in the early 21st C.

Title Adaptive Mechanism for Smart Street Lighting System Type Journal Article
Year 2019 Publication Smart Intelligent Computing and Applications Abbreviated Journal (up)
Volume 160 Issue Pages 69-76
Keywords Lighting
Abstract The adaptive street light has the ability to adapt to the motion of cycles, cars and pedestrians. It uses motion as well as light sensors to detect the traffic and light around. It dims when there is no movement on the road, and is brightened when there is any activity. Smart street lights are very dissimilar from the old methods of lighting. It is an automated system that will be able to automate the streets. The main objective of these lights is to decrease the utilization of power, while no activity is detected on the street. It will be switched ON while there are pedestrians and cars on the street or else they will get dimmed to 20% of the brightness. The proposed approach gives a method to conserve power by using the PIR sensors to sense the incoming traffic and hence turning ON a cluster of lights surrounding the traffic. As the traffic is passing by, the street lights left behind will dim on its own. Hence, a lot of power can be conserved. Also, during the day time when there is no need of light the LDR sensor will sense the light and the light will remain switched OFF. This smart street light system comes under the domain of smart city.

Title Home Sweet Home. Connecting the dots for healthy evening residential illumination Type Journal Article
Year 2019 Publication ARC Lighting In Architecture Abbreviated Journal (up)
Volume Issue Pages 55-60
Keywords Lighting; Human Health
Abstract During the twentieth century, lighting designers would commonly use incandescent light sources for residential homes as they provided a visual comfort, with high quality colour rendering properties, along with relaxing ambient atmosphere. Unfortunately, it’s now difficult to buy incandescent light sources because they have been banned in many countries (https://bit.ly/2GwN2Wv). This article addresses some of the challenges in regards to health, brought about by the changeover to new LEDs and other related technologies, and tries to offer some context on how to keep up with these rapid transformations. While we know it’s necessary to limit blue-rich light at night (as it prevents melatonin production and impaires nocturnal sleep), and that it’s important to maximise exposure to the blue wavelength of light in the morning (to trigger circadian timing, increase alertness), there are other issues that are misunderstood and often ignored. This includes flicker from LEDs and electromagnetic fields (EMFs), which can be produced by smart home lighting technology.

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 1911 Publication University of Illinois Bulletin Abbreviated Journal (up)
Volume 9 Issue 8 Pages Bulletin No. 51
Keywords Lighting; Energy; Economics; Planning
Abstract It is the purpose of this bulletin to make available information concerning street illumination. The suggestion which led to this compilation came from the many inquiries received by the Electrical Engineering Department each year from those interested in framing ordinances permitting corporations or individuals to operate street lighting systems. An attempt has been made to present this information in such a form as to be readily understood by the general public, without requiring any special technical knowledge. The data have been compiled from reliable sources, and checked in many instances by tests conducted by the writers.
