Thermal comfort range and influence factor of urban pedestrian streets in severe cold regions

Summary

This empirical study investigates outdoor thermal comfort on two pedestrian streets in Harbin, China, using on-site microclimate measurements and pedestrian surveys across different seasons. The researchers establish a locally adapted Universal Thermal Climate Index (UTCI) assessment and identify an acceptable thermal range of −3.8°C to +23.0°C for more than 80% of respondents. The findings demonstrate that thermal adaptation, length of residence, activity type and demographic characteristics influence perceived comfort, with long-term residents showing greater tolerance of cold conditions. The study provides valuable evidence for assessing pedestrian thermal comfort and developing climate-responsive street environments that support walking throughout the year.
