This dissertation focuses on thermal comfort and walking as an experiential phenomenon in outdoor urban environments. The goal of the study is to provide a better understanding of the impact of psychological adaptation factors on thermal comfort. The main research questions included the impact of psychological factors on outdoor thermal comfort as well as the impact of long-term thermal perception on momentary thermal sensation. My research follows a concurrent triangulation strategy as a mixed-method approach, which consisted of a simultaneous collection and analysis of qualitative and quantitative data. Research consisted of five rounds of data collection in different locations beginning February 2018 and continuing through December 2019. During the qualitative phase, I gathered data in the form of an open-ended questionnaire but importantly, self-walking interviews where participants narrated their experience of the environment while recording one-minute long videos. The visual and audible information was first processed using thematic analysis and then further analyzed via Latent Dirichlet Allocation (LDA). During the quantitative phase, I gathered information from participants in the form of three-step survey questionnaires, that data was analyzed using T-Test regression analysis in STATA. The quantitative data helped explore and address the initial research questions, while the qualitative data helped in addressing and explaining the trends and the experiential aspects of thermal environment.

Results revealed that spatial familiarity (as a psychological adaptation factor) has a significant relationship for both overall comfort and thermal comfort within outdoor environments. Moreover, long term thermal memory influences momentary thermal sensation. The results of qualitative and quantitative data were combined, compared, and contrasted to generate new insights in the design of outdoor urban environments. The depth and breadth of the qualitative data set consisting of more than a thousand minute-long of narrated video segments along with hundreds of pages of transcribed text, demonstrated the subjective aspects of thermal comfort. This research highlights the importance of context-based and human-centric design in any evidence-based design approach for outdoor environments. The implications of the study can provide new insights not only for architects and urban designers, but also for city planners, stakeholders, public officials, and policymakers.
