In anticipation of the 2032 climate-positive Olympic Games in Brisbane, we address the Urban Heat Island (UHI) effect optimizing the granularity of a sensor network in the Northshore Hamilton Priority Development Area (PDA), i.e., the location of the Athletes' Village, for efficient environmental monitoring and the provision of a Green Information System (IS). We use spatio-temporal sensor data and leverage advanced interpolation techniques to optimize both temporal and spatial granularity settings. Results and findings from our granularity analysis reveal an optimal temporal granularity at one-hour intervals, providing the optimal trade-off balance between computational efficiency and sufficient detail for urban planning. Finer temporal resolutions do not significantly enhance prediction accuracy. Spatial analysis further helps decision makers to balance trade-offs between economic costs and prediction accuracy, eliminating unnecessary sensors in the network.
