Title (down) What is French about the “French fear of darkness”? The co-production of imagined communities of light and energy Type Journal Article
Year 2019 Publication Journal of Energy History Revue d'Histoire de l'Energie Abbreviated Journal
Volume 2 Issue Pages
Keywords History; Society; Energy; Lighting; France
Abstract This essay takes expert assumptions about light preferences as a starting point for a historical inquiry into what I call imagined sociotechnical communities of light and energy. My argument is that historical energy supply systems produced these imaginaries and vice versa, shifting the scales at which public lighting was envisioned and darkness was acceptable. While in the 17th C. dark streets were the norm and even the illumination of single streets was publically contested, innovators of the 18th C. imagined gas light and energy on an urban scale. In the 20th C., electric lighting promoted electrification and the electricity supply systems in countries like France allowed experts to think and standardize lighting at a national level. In the 21st C. the expert imaginary of a light-loving French people is challenged by public environmental concern.

Title (down) What Happens in the Shadows: Streetlights and How They Relate To Crime Type Journal Article
Year 2017 Publication Abbreviated Journal
Volume Issue Pages
Keywords Crime; Lighting
Abstract After finding in a previous report, “Streetlights in the City: Understanding the Distribution of Houston Streetlights,” that the city of Houston’s more than 173,000 streetlights were not evenly distributed throughout the city, this next report answers the question: do places with more streetlights have lower crime rates?

The findings complicate the common perception that more streetlights lead to fewer crimes. While there was some evidence that a particularly high density of streetlights can provide protective benefits, excluding those extremes provides a much muddier picture, suggesting that crime is a reflection of other neighborhood contexts. As such, cities should be cautious in expecting direct reductions in crime with the introduction of more streetlights.

Title (down) Visual wayfinding for partially sighted pedestrians – The use of luminance contrast in outdoor pavings Type Journal Article
Year 2018 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology
Volume in press Issue Pages in press
Keywords Lighting
Abstract An increase in the number of partially sighted people is one of the effects of population ageing. These people have great difficulties in gathering wayfinding information to move independently in an unfamiliar environment. Guide paths based on the luminance contrast between a strip and surrounding surfaces can be an effective device for mitigating these difficulties, but information provided by the scientific literature on guide paths cannot be usefully applied to the naturally coloured paving materials most commonly found in pedestrian urban spaces. This paper presents a simplified method for measuring the luminance contrast between a guide strip and its background using combinations of naturally coloured paving materials.

Title (down) Use of Space Syntax Technique to Improve the Quality of Lighting and Modify Energy Consumption Patterns in Urban Spaces Type Journal Article
Year 2018 Publication European Journal of Sustainable Development Abbreviated Journal
Volume 7 Issue 2 Pages 29-40
Keywords Lighting
Abstract Urban lighting is one of the significant issues that urban designers and architects are facing, and it has received a special attention in recent years. Urban lighting pursues critical goals such as preserving the livability of the city during nighttime, providing a sense of security, maintaining the city‟s readability, etc. Use of incompatible patterns for lighting design wastes significant amount of energy annually. A master lighting plan for urban areas should be recommended to achieve these goals and prevent wasteful energy use in lighting. One of the solutions for designing an appropriate plan is to notice the pedestrian traffic pattern in the city by considering space syntax model and integration maps analysis. In this research, one of Tehran‟s regions has been chosen and its integration map has been generated using appropriate software. Tehran is selected as case study of this research while the results might be applied in other similar cities especially in developing countries. First, based on the integration degree of the passages which reveals pedestrian traffic pattern and considering recommended illuminance standards, the average required lighting has been determined. Second, comparing the measured lighting intensity and the standard amounts reveals the correlation between the presented urban lighting and energy consumption model. Eventually, different solutions for appropriate urban lighting design based on acceptable energy consumption patterns have been suggested.
