Abstract: Short-term thermal history may have a substantial impact on how a person feels when traversing through urban spaces, especially in the context of global warming, as increasing temperatures and heat wave frequency will limit the quality and safety of their experience. While dynamic thermal comfort models such as Dynamic Thermal Sensation (DTS) are available, most analysis methodologies currently applied in urban design rely on steady state models and tend to overlook the thermal history of occupants. This paper implements a DTS-based thermal comfort analysis workflow to predict the evolving thermal sensations of occupants along a path. The workflow is then applied in the analysis of a design project in Southeast Asia, to assess its effectiveness in evaluating design scenarios in comparison with a steady state Universal Thermal Climate Index (UTCI) model.
