The Pub already uses the very common incandescent light bulbs as their main lighting source in the common area, but this report will delve into whether the Pub should switch to the more sustainable, yet less common CFL or LED lighting. The analysis and comparison of the three technologies in question, namely incandescent, CFL, and LED lighting, will take the form of a triple bottom line assessment.This triple bottom line assessment will measure the social, environmental, and economic impact of each of the three lighting methods. The primary research for the investigation was gathered through a personal tour of Koerner’s Pub and its energy utilities provided by our stakeholder Mr. Tim Yu. On the other hand, all secondary research was obtained through various websites, peer-reviewed papers, and books. The cumulative social appraisal conducted shows that in terms of social sustainability, LED lighting is the best out of the three options. The environmental assessment prefers the use of LEDs due to their lack of any environmentally hazardous elements and their decreased amount of waste produced in the long term. The last area of study in this triple bottom line assessment, the economical assessment, concludes that LEDs are the most cost -efficient form of lighting that can be utilized by Koerner’s Pub. In conclusion, the study shows that LEDs are indeed the most sustainable form of lighting and would be the most advantageous lighting option for Koerner’s Pub. iiTABLE OF CONTENTSABSTRACT iiLIST OF
