This article performs a retrofitting simulation approach using light emitting diode instead of sodium high pressure luminaries; in addition, executes a cost-benefit analysis evaluating technical and economical aspects from the case of study. The illuminance simulation was executed by DIAlux. For performing the study, CA-13 roadway, La Ceiba, Honduras, was selected. The studied roadway is extremely relevant considering that connects with part of the Central American Atlantic region.
Findings from the study demonstrate that although the initial costs of retrofitting conventional lighting to LED are high, the energy and maintenance savings are considerable, and these are the main motivations for why many cities worldwide conduct LED street lighting projects. For the proposed case, the energy consumption saved accounts for 233 MWh (53.3%) annually. Monetarily, savings ascend to USD 38,987 annually compared to the usage of high-pressure sodium lamps (HPS). Financially, this is a viable project, the payback is in 5 years, the NPV is a positive value of USD 196,689, and there is a high IRR of 20.5%, being an attractive percentage for potential investors. Moreover, the benefit-cost ratio equals to 1.83, this value being greater than one, indicates that the project is economically viable. Finally, results from this research indicate that the reduction of GHG emissions by implementing the LED lighting technology would be 77.5 tCO2 annually.
In conclusion, LED roadway lights offer an effective and increasingly cost-effective solution to the development challenge of municipal energy consumption, roadway light network expenditures, greenhouse gases emissions reduction and urban quality.
