The impact of cultural and climatic background on thermal sensation votes

The increasing number of migration and the creation of multicultural cities have generated a new challenge for urban designers. The design of shared, welcoming and well utilised urban open places is important in order to promote inclusion, interaction, belonging, and diversity within cities. Thermal comfort is directly related to the users' attitude and behaviour in outdoor places. Fulfilling the comfort needs for users having a variety of cultural and climatic backgrounds needs therefore to be taken into consideration. Microclimatic parameters strongly affect thermal sensation, however, physical, physiological and psychological adaptation have also proven to have significant influence. The satisfaction with the thermal environment does not only depend on the place, but also on personal variables people bring to that place with them. The paper investigates the role of the culture and climatic background of users' in the complex relationships between microclimate, thermal adaptation factors and human behaviour in open public places. The paper aims to understand the influence of users' cultural and climatic background variations on their thermal needs and usage of the outdoor places. Climatic measurements, surveys and observations were carried out in Federation square in Melbourne along the year to examine thermal comfort and patterns of behaviours of users having different cultural origins. Quantitative analysis is used to examine the influence of culture and climatic background of the users' on thermal sensations and adaptation factors. The findings contribute to guiding the design of outdoor public places in multicultural cities.

Applying the adaptive model of comfort

This note is directed to one major aspect of the comfort of building occupants – namely, thermal comfort. Even though it may be difficult to isolate thermal sensations from the whole of comfort itself, humans have a strong physiological connection with their thermal environment. Our thermal perceptions and sensations often vary greatly, especially between our indoor and outdoor environments. We may be totally comfortable lounging under a shade cloth on a 35°C day with a stiff breeze enveloping our body, but would never tolerate similar conditions indoors. Such divergent perceptions of the same thermal stimulus across differing contexts raise countless questions about just what the determinants of thermal comfort actually are, and how they may be managed against the demands for an environmentally responsive architecture.
