A review of cultural background and thermal perceptions in urban environments

Thermal comfort is among the chief indicators of the sustainability of outdoor spaces. However, the complex nature of comfort represents the interaction of several determinants that leads to a perception of the thermal environment. Recently, researchers have paid particular attention to non-physical factors to understand the mechanisms involved in thermal perceptions in urban environments. The extant literature has contended that culture and cultural background are determinants to individuals’ thermal perceptions. Therefore, this study aimed to review how the link between outdoor thermal comfort (OTC) and cultural background is investigated. This is, to the best of our knowledge, the first review study on the subject. The study used a systematic literature review approach based on secondary data available in relevant and contemporary literature. The findings first showed the scarcity of research on cultural background and OTC; however, all studies identified corroborated the significant impact of cultural background on thermal perceptions. Notably, the cultural background was found to be the source of variation in thermal perceptions, tolerance to, and preference for certain thermal conditions, thermal comfort requirements and expectations, choice of clothing, and environmental attitudes. The findings provide a sound basis for future researchers to address the research gaps identified. The study also raises policy makers’ and designers’ awareness of urban environment users’ genuine needs and requirements.
