Thermal comfort based performance appraisal of covered walkways in Singapore

This paper describes an ongoing research project to establish a thermal comfort based walkway performance analysis that embodies the effect of context and climate. This study combines the survey data (perceived comfort) from walkway users and thermal sensor data (actual thermal comfort) collected at various covered walkways across Singapore. One contribution is the combination of subjective and objective comfort measurements in a tropical context . We work with descriptive statistical measures to help better understand the ranges of thermal comfort offered by covered walkways. This research highlighted that the comfort offered by current walkways were identified to have no significance, and the walkways are unable to reduce the heat stress into the moderate range at all times of the day. A key contribution of this research project identified missing datasets and help improve our data collection methodology for the future expansion dataset that employ machine learning.
