Title Graph-Based Spatial Data Processing and Analysis for More Efficient Road Lighting Design Type Journal Article
Year (down) 2018 Publication Sustainability Abbreviated Journal Sustainability
Volume 10 Issue 11 Pages 3850
Keywords Lighting
Abstract The efficiency and affordability of modern street lighting equipment are improving quickly, but systems used to manage and design lighting installations seem to lag behind. One of their problems is the lack of consistent methods to integrate all relevant data. Tools used to manage lighting infrastructure are not aware of the geographic characteristics of the lit areas, and photometric calculation software requires a lot of manual editing by the designer, who needs to assess the characteristics of roads, define the segments, and assign the lighting classes according to standards. In this paper, we propose a graph-based method to integrate geospatial data from various sources to support the process of data preparation for photometric calculations. The method uses graph transformations to define segments and assign lighting classes. A prototype system was developed to conduct experiments using real-world data. The proposed approach is compared to results obtained by professional designers in a case study; the method was also applied to several European cities to assess its efficiency. The obtained results are much more fine-grained than those yielded by the traditional approach; as a result, the lighting is more adequate, especially when used in conjunction with automated optimisation tools.

Title Estimating the relative contribution of streetlights, vehicles, and residential lighting to the urban night sky brightness Type Journal Article
Year (down) 2018 Publication Lighting Research & Technology Abbreviated Journal Lighting Res & Tech
Volume Issue October 2018 Pages
Keywords Remote Sensing; traffic; Roadway lighting
Abstract Under stable atmospheric conditions the brightness of the urban sky varies throughout the night following the time course of the anthropogenic emissions of light. Different types of artificial light sources (e.g. streetlights, residential, and vehicle lights) have specific time signatures, and this feature makes it possible to estimate the amount of brightness contributed by each of them. Our approach is based on transforming the time representation of the zenithal night sky brightness into a modal expansion in terms of the time signatures of the different sources of light. The modal coefficients, and hence the absolute and relative contributions of each type of source, can be estimated by means of a linear least squares fit. A practical method for determining the time signatures of different contributing sources is also described, based on wide-field time-lapse photometry of the urban nightscape. Our preliminary results suggest that, besides the dominant streetlight contribution, artificial light leaking out of the windows of residential buildings may account for a significant share of the time-varying part of the zenithal night sky brightness at the measurement locations, whilst the contribution of the vehicle lights seems to be significantly smaller.

Title More-than-human media architecture Type Journal Article
Year (down) 2018 Publication Abbreviated Journal
Volume Issue Pages
Keywords Architecture; Lighting; Planning
Abstract We consider some of the planetary conditions and global circumstances that both research and practice of media architecture are embedded within, such as climate change, pollution, resource consumption, and loss of biodiversity. While there has been a notable increase in emphasis on participation and engagement in design and use, with the aim to increase the involvement of diverse and often marginalised citizens, a human-centred approach to media architecture comes with its own set of problems. In this paper, we want to draw the attention of the media architecture community to the fallacy of human exceptionalism and anthropocentrism. We present a critical review of examples of media architecture projects and installations that question our understanding of urban space as separate from nature, and designed primarily for humans and just humans. Informed by studies in disciplines such as science and technology studies, critical geography, urban planning, and interaction design, we use insights derived from our review to discuss ways towards a more-than-human approach to media architecture. We conclude by proposing for discussion nascent design considerations for media architecture to go beyond the needs of just humans and to consider new ways to appreciate and cater for our broader ecological entanglements with plants, animals, and the environment at large.

Title Application of power line communication technology in street lighting control Type Journal Article
Year (down) 2018 Publication International Journal of Design & Nature and Ecodynamics Abbreviated Journal Int. J. DNE
Volume 13 Issue 2 Pages 176-186
Keywords Lighting
Abstract Rapidly increasing usage of telecommunication systems causes new transmission technologies and networks to emerge. Not only the efficiency, reliability and accessibility of the network are important, but also the economic issues. One cost-effective solution could be power line communication (PLC) technology, which transmits data using the existing electricity infrastructure. The application of this communication technique is an attractive and innovative solution for the realization of smart cities and smart homes. With intelligent control networks, energy savings can be optimized and the operating as well as maintenance costs can be reduced. Since outdoor lighting systems are the major consumers of electricity, to create a modern, energy-efficient city, intelligent street lighting control is needed. This paper provides an overview of power line communication principles including the theoretical background of data communication, modulation techniques, channel access methods, protocols, disturbances and noises. Furthermore, in order to highlight the benefits of a PLC-based street lighting control system, a pilot project will be presented.

Title Use of Space Syntax Technique to Improve the Quality of Lighting and Modify Energy Consumption Patterns in Urban Spaces Type Journal Article
Year (down) 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.
