Análise da eficiência do sistema de iluminação pública do Brasil

Abstract

This research aims to analyze the efficiency of the Public Lighting system in Brazil through the creation of a general indicator of the performance of lamps, since they are the main element of public lighting and, therefore, can effectively contribute to the improving energy efficiency by reducing consumption and demand at the peak and reducing waste, attending the needs of the population, and not burdening the system. The individual analysis of performance parameters does not allow defining which type of lamp is more efficient, which also makes it difficult to understand how Brazil has evolved and what are the prospects for growth in the country's public lighting system. Thus, from the definition of the main technical parameters and by collecting data from different models of lamps, an average value was calculated for each parameter, which was then normalized on a scale from 0 to 5. From the assignment of different weights to each parameter, the general indicator of performance of lamps was created and based on surveys of public lighting points in Brazil, a general indicator of system performance was also created. The results showed that LED lamps are the most efficient on the market, followed by sodium vapor lamps, which are predominant in the Brazilian public lighting system. In addition, the survey revealed the changes promoted over the last decades were positive, but the pace of modernization is slow, and the impact is still insufficient for the system to reach more satisfactory levels of efficiency. Thus, the performance of the system will always be linked to its ability to absorb new technologies quickly.
