UBC Campus Outdoor Lighting : Challenges and Opportunities Khalid, Mustafa; Yong, Melissa; Lin, Tingli

Abstract

The objective of our report is to stimulate discussions with regards to campus outdoor lightings. This report: • provides a brief historical overview of the evolution of artificial light, • examines the current technological trends of outdoor lighting, • outlines some of the potential negative impacts of outdoor lighting, and • provides recommendations for campus stakeholders and future policy makers to implement. The significance and importance of light in our lives is undeniable. Light provides us with more than just an illumination in the dark. Its significance is evident from history and in modern day researches done on the subject of light. The white light we see is a combination of a spectrum of colours and this spectrum is further reflected in the many ways light affects people, nature and the world. Recent advancements in technology, from more efficient lighting components to increasingly sophisticated controls, offer attractive opportunities for making the most of outdoor lighting systems. Hence, the team makes the case for the University of British Columbia to shift to using LED technology. The team recommends before determining what type of lighting should be installed or retrofitted, it is important to ask the basic question: Is Lighting needed? If no reason for lighting can be found, it is more practical to remove the current lighting than replacing it with a new technology. we also recommend the following: 1. luminance for all new lights should be equal or less than the maximum value recommended by Illuminating Engineering Society. 2. integration of bi-level control systems as it is unnecessary to keep the street lighting at maximum illumination during periods of low traffic. 3. all new lights installed anywhere on campus to be properly shielded. These shields should ensure that light is directed downwards - not upwards or to the side. 4. a campus lighting strategy to establish a method for assessing future lighting solutions. We recommend combining the individual assessments for each of the four components to determine whether the proposed lighting solution is acceptable. 5. comprehensive integration of CPTED strategies: to improve poor design features such as isolation, lack of sight lines, and hiding and entrapment spots, it will contribute to a safer and more appealing campus environment.
