Abstract

The thermal environments of five local climate zones (LCZs) in summer were investigated using all measured microclimatic data collected from 9:00 on 3 August until 15:30 on 4 August, 2017. The physiological equivalent temperature (PET) and universal thermal climate index (UTCI) of the human thermal environment were highest in LCZ E B (paved with scattered trees) and lowest in LCZ 2 B (compact mid-rise with scattered trees) and LCZ 4 (open high-rise) during the daytime, and highest in LCZ 4 and lowest in LCZ D (low plants) during the nighttime. LCZ D and LCZ E B in the park and LCZ 5 (open mid-rise) revealed similar thermal environments, and LCZ 2 B and LCZ 4 showed higher PET and UTCI values for the thermal environment. The maximum mean difference by location was 6.7 °C for PET and 3.7 °C for UTCI during the daytime, a one-level difference in PET and a two-thirds level in UTCI. During the nighttime, the maximum mean difference was 2.3 °C for PET and 1.9 °C for UTCI, a one-third-level difference. Compared to LCZ 2 B , the PET showed a maximum difference of 11 °C and UTCI of 6 °C, showing a difference of two levels for PET and one level for UTCI.
