Abstract(s)
To measure urban outdoor pedestrian thermophysiological comfort mobile roving missions were
conducted in all seasons of the year during the day and at night. Six routes were chosen, representing areas of the city with varying urban morphological layouts. The thermal comfort
conditions were analysed using the Local Climate Zone spatial scale. This enabled the identification of typologies of areas where pedestrians might feel (un)comfortable. To achieve the proposed objectives, quantitative and qualitative analysis were run, namely a Linear Mixed-Effect
Model. This model was useful to understand the thermal behaviour of the roved areas by comparison to a reference area. The city was found to be generally cooler, except at night when it can
have a 44% increased UTCI. Most collected values throughout the year had ‘no thermal stress’,
except in the summer when ‘moderate’ and ‘strong heat stress’ was predominant. Compact and
large low rise urban areas were found to be the most uncomfortable. Significant amplitudes were
found in some LCZs, reaching as high as 7 ◦C in some scenarios. Sparsely wooded areas exhibited
higher values in all seasons and at night, except in the summer. This showed that for a local heat
stress analysis a higher resolution scale is needed.
