A influência dos parâmetros urbanos de Aracaju/SE na geração de energia solar fotovoltaica das edificações: estudo de caso da zona de adensamento preferencial 4

Abstract

The vertical development of cities and the definition of urban planning parameters directly influence the amount of solar radiation reaching buildings, affecting aspects relating to environmental comfort and the utilisation of solar energy. In this context, the overall objective of this final-year project is to assess the influence of urban planning parameters in the city of Aracaju, Sergipe, on the efficiency of solar photovoltaic systems. The research was carried out through a literature review, an analysis of current urban planning legislation, three-dimensional modelling of different urban scenarios, and computer simulations of annual and seasonal global illuminance and the incidence of direct solar radiation. Among the scenarios analysed, the model with an occupancy rate of 50% and a utilisation coefficient of 1 (the Control scenario) performed best, whilst an increase in the utilisation coefficient significantly reduced illuminance levels. Doubling the utilisation coefficient reduced illuminance by around 10%, whilst quadrupling it resulted in a reduction of approximately 30%. In contrast, increasing the occupancy rate caused only minor variations, of around 2%. The results indicate that limiting the utilisation coefficient, combined with higher occupancy rates, promotes solar access in buildings. The results indicate that limiting the utilization coefficient, combined with higher occupancy rates, promotes solar access in buildings. It is concluded that the interaction between urban planning parameters influences the solar performance of buildings, as evidenced.
