Title More-than-human media architecture Type Journal Article
Year 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 Streetlights in the city: understanding the distribution of Houston streetlights Type Journal Article
Year 2017 Publication Abbreviated Journal
Volume Issue Pages
Keywords Lighting; Society
Abstract There are at least 173,724 streetlights in the city of Houston, or about 15 streetlights per mile of roadway in the average Houston neighborhood. But there is wide variation in streetlight density across those neighborhoods. This report offers several important findings. First, black and Hispanic neighborhoods have higher concentrations of streetlights than white neighborhoods. Second, mixed-income neighborhoods tend to have higher concentrations of streetlights than the city’s wealthiest and poorest neighborhoods.

In the context of this discussion, we should consider the possibility that some areas of the city are overly lit in addition to being concerned about the places without enough lights. There may be a point at which having more lights actually becomes a negative. We need to get a better understanding of the lived consequences of the level of available lighting before making any further decisions regarding city streetlights.

Title Estimating the relative contribution of streetlights, vehicles, and residential lighting to the urban night sky brightness Type Journal Article
Year 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 Graph-Based Spatial Data Processing and Analysis for More Efficient Road Lighting Design Type Journal Article
Year 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 Producing uniform illumination within a rectangular area by using a nonimaging optic Type Journal Article
Year 2018 Publication Applied Optics Abbreviated Journal Appl. Opt.
Volume 57 Issue 31 Pages 9357
Keywords Lighting
Abstract This paper proposes a new design method to create a novel optical element to generate uniform illumination within a rectangular area. Based on this model, an illuminated area is irradiated by two sets of rays; the first one irradiates the target plane after refraction from the top section of the lens, and the second one irradiates from the reflection at the side profile of the lens and then from refraction at the top part of the lens. The results show that a uniformity of over 90% can be achieved.
