  Title Upgraded Rig Lighting Improves Night Time Visibility While Reducing Stray Light and the Threat to Dark Skies in West Texas Type Conference Article
  Year 2015 Publication Society of Petroleum Engineers Abbreviated Journal Soc. Petrol. Engr.  
  Volume Issue Pages  
  Keywords Lighting; outdoor lighting; petroleum; oil and gas; lighting engineering  
  Abstract McDonald Observatory, part of the University of Texas at Austin, is a world-class astronomical-research facility representing hundreds of millions of dollars of public and private investment that is increasingly threatened by nighttime lighting from oil-and-gas-related activities in and around the Permian Basin. Established in the remote Davis Mountains of West Texas in 1932, the observatory is home to some of the world's largest telescopes and it has continued as a world-renowned research center. Dark night skies are crucial to its mission. Since 2010, however, the sky along the observatory's northern horizon, in the direction of the Permian Basin, has been steadily and rapidly brightening, due to new exploration for oil and gas. The pace has been accelerating: More than 2,000 applications were filed over the past year to drill in the region. In 2011, the State of Texas enacted a law that instructs the seven counties surrounding McDonald Observatory, an area covering some 28,000 square miles, to adopt outdoor lighting ordinances designed to preserve the dark night skies for ongoing astronomical research at the observatory. Most had already done so voluntarily, but additional effort is needed throughout the area to address fast-moving energy-exploration activities.

A joint project between McDonald Observatory and Pioneer Energy Services (PES) has demonstrated that many of the adverse effects of oilfield lighting can be mitigated, without jeopardizing safety, through proper shielding and aiming of light fixtures. Beginning July, 2013, PES granted the observatory access to a working rig, Pioneer Rig #29. Every time the rig moved to a new location, there was an opportunity to install shields, re-aim floodlights, and evaluate effectiveness.

This joint project demonstrated that, in many cases, nighttime visibility on the rig can be significantly improved. Many light fixtures, which had been sources of blinding glare due to of lack of shielding, poor placement, or poor aiming, were made better and safer, using optional glare shields that are offered by manufacturers for a variety of fixture models. Proper shielding and aiming of existing fixtures improves visibility and reduces wasted uplight. New lighting systems that take advantage of light-emitting-diode technology also promise better directionality, reduced fuel consumption, and darker skies overhead.

The oil-and-gas industry has been lighting its exploration and production activities in much same way for more than 100 years, with little to no consideration of environmental impacts. The opportunity exists to adopt new lighting practices and technologies that improve safety, reduce costs, and help preserve our vanishing night skies so that important ongoing scientific exploration can continue.

  Title Illuminance Reconstruction of Road Lighting in Urban Areas for Efficient and Healthy Lighting Performance Evaluation Type Journal Article
  Year 2018 Publication Applied Sciences Abbreviated Journal Applied Sciences  
  Volume 8 Issue 9 Pages 1646  
  Keywords Instrumentation; Lighting; Planning  
  Abstract Big lighting data are required for evaluation of lighting performance and impacts on human beings, environment, and ecology for smart urban lighting. However, traditional approaches of measuring road lighting cannot achieve this aim. We propose a rule-of-thumb model approach based on some feature points to reconstruct road lighting in urban areas. We validated the reconstructed illuminance with both software simulated and real road lighting scenes, and the average error is between 6 and 19%. This precision is acceptable in practical applications. Using this approach, we reconstructed the illuminance of three real road lighting environments in a block and further estimated the mesopic luminance and melanopic illuminance performance. In the future, by virtue of Geographic Information System technology, the approach may provide big lighting data for evaluation and analysis, and help build smarter urban lighting.

  Title An investigation of LED street lighting's impact on sky glow Type Journal Article
  Year 2017 Publication Abbreviated Journal  
  Volume PNNL-26411 Issue Pages  
  Keywords Skyglow; Lighting  
  Abstract A significant amount of public attention has recently focused on perceived impacts of converting street lighting from incumbent lamp-based products to LED technology. Much of this attention pertains to the higher content of short wavelength light (commonly referred to as “blue light”) of LEDs and its attendant influences on sky glow (a brightening of the night sky that can interfere with astronomical observation and may be associated with a host of other issues). The complexity of this topic leads to common misunderstandings and misperceptions among the public, and for this reason the U.S. Department of Energy Solid-State Lighting Program embarked on a study of sky glow using a well-established astronomical model to investigate some of the primary factors influencing sky glow. This report details the results of the investigation and attempts to present those results in terms accessible to the general lighting community. The report also strives to put the results into a larger context, and help educate interested readers on various topics relevant to the issues being discussed.

  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 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 On the impact of safety requirements, energy prices and investment costs in street lighting refurbishment design Type Journal Article
  Year 2018 Publication Energy Abbreviated Journal Energy  
  Volume in press Issue Pages in press  
  Keywords Lighting; Economics; Energy; Planning  
  Abstract Street lighting is an indispensable feature for the night landscape of cities. It is important for road safety, users visual comfort, crime prevention and to augment the perceived personal safety. Realize and maintain an adequate street lighting service is very expensive for municipalities with significant impact on their budgets. For this reason, special attention should be paid to the design of new street lighting systems and to the refurbishment of existing ones, since many of them are inadequate. In light of this it is very important to implement street lighting designs that fulfil lighting requirements avoiding energy waste and light pollution and, at the same time, result economically sustainable for municipalities. In this paper, an original step by step methodology for the lighting, energy and economic analysis of street lighting refurbishment designs has been introduced and explained in detail. The methodology is suitable for use in cities of different sizes. As an applicative example, the methodology has been tested in the town of Pontedera (Italy) and the results are discussed, also providing a sensitivity analysis of the economic feasibility with respect to the variations of electricity prices and investment costs.
