Comparisons of urban morphology and microclimatic condition among the different estates were analysed. In general, it is found that, compared to B2, BPD has a lower mean SVF value, more extensive greenery, higher building height and building mass, a significantly larger proportion of greenery but lesser pavements and building area, and lower building density. There is a decreasing trend in the mean ambient air temperature observed along with the transformation of industrial developments over time. B2 has higher mean air temperature than BPD at all times of the day. B2 has lower diurnal temperature range than BPD which infers that BPD is generally more effective in reducing the heat island intensity.
