However, the LCZ method has significant limi-tations regarding the possibility to cover the many urban layouts that characterise real cities.  The aim of this study is to show that a different set of morphology parameters would be more ef-fective in capturing the summer and winter climate performance of real urban textures.METHOD: A comparative analysis of UHI intensity was performed with the Urban Weather Genera-tor model (Bueno et al. 2013) considering representative urban textures of Rome (Italy), Barcelona (Spain) and Santiago (Chile). RESULTS:  A significant variability of UHI intensity was found among  urban textures classi-fied as “compact mid-rise” (10< h <25) and “compact high-rise” (h > 25) in the LCZ. Regression analyses highlighted differentiated contributions of the three urban morphology parameters used by UWG on summer and winter UHI intensity and the importance of the density of facades during both seasons. Therefore, the results suggest that the three parameters used by UWG could be used in urban planning to compare and optimise the climate behaviour of urban structures.A. Salvati*(a) M.
