Abstract
This report presents the outcome of two biometeorological campaigns aiming to calibrate the Physiological Equivalent Temperature heat stress index (PET) locally against individual thermal perception. PET is widely used in evaluations of heat mitigation strategies. The study also aspired to determine whenever differences in individual thermal sensitivity exist between a commercial and a residential area, and a fortiori a pocket urban park.
The campaigns took place during the 2018 and 2019 wet and dry inter-monsoon periods and focused on the Tanjong Pagar mixed-use downtown precinct. The results revealed a significant seasonality in the individual thermal sensitivity and high spatial variations that are recommended to be taken into account when assessing OTC site performance. Surprisingly the pocket urban park presents poor OTC performance compared to the other built-up commercial sites. It can be attributed to the lack of sun shelter at noon despite its green nature.

Notes
Dr. Kohler (NUS-SMU) conducted the outdoor thermal comfort campaigns. She designed the research protocol and survey questionnaire, cleared the research permit and ethic for the two OTC campaigns. She was personally in charge of the meteorological condition monitoring campaign of the Tanjong Pagar campaign and administrated the OTC survey with the help of the NUS urban climate lab team and 8 NUS research assistants. During the Duxton OTC campaign, she was helped by Dr. Acero (SMART) who supervised and managed the meteorological condition monitoring in the Duxton park. The collection of this dataset was facilitated by the help of the CS team. Dr. Kohler analysed the whole datasets and compiled them in this technical report. Ms. Ruefenacht facilitated the coordination of the Duxton OTC campaign as coordinator of the CS1.5 project. Dr. Philipp assisted Dr. Kohler in fieldwork in both OTC campaigns in administrating the OTC survey questionnaire to the recruited participants and further and nicely took the responsibility to upload the technical report in the ETH publication collection. Prof. Dr. Chow (NUS-SMU) supervised the whole work.More
