Interpreting ENVI-met Simulated Microclimate Data with Measured Observations in HFT Stuttgart

Abstract

This study investigates the impact of green surface areas on urban microclimates using ENVI-met simulation software, focusing on Hochschule für Technik Stuttgart (HFT Stuttgart). The study validates ENVI-met's accuracy in predicting microclimatic conditions and recommends urban design strategies to mitigate the Urban Heat Island (UHI) effect. Findings show significant temperature reductions in areas converted from paved to green surfaces, with decreases of up to 1.15°C in Block 1, 0.70°C in Block 2, and 1.00°C in Block 3. Statistical analysis reveals strong correlations between measured and simulated data, with maximum R² values of 0.81 for temperature and 0.93 for humidity, confirming the model's reliability. The study emphasizes the importance of integrating green surfaces into urban planning to enhance thermal comfort and sustainability, validating ENVI-met as a robust tool for micro-climate analysis
