Geographical Variations in Thermal Comfort Preferences Based on ASHRAE Database II

Thermal comfort is a fundamental aspect of daily life, influencing our well-being in various 
environments. Understanding thermal comfort preferences across geographical locations is crucial for 
designing buildings and urban spaces that promote occupant satisfaction. This research investigates the 
factors contributing to thermal comfort, including air temperature, humidity, and air velocity. It further 
explores how individuals' origins and cultural backgrounds shape their perception of thermal comfort. 
The study examines the influence of geographic location on human thermal comfort within specific 
environments. We hypothesize that people in different regions develop varying thermal preferences due to 
climatic differences and acclimatization. This research utilizes a seven-point thermal sensation scale to 
assess comfort and analyzes acceptable ranges of ambient air temperature, relative humidity, and air 
velocity for diverse climate zones. We expect to find variations in thermal sensation patterns across 
geographical locations, along with differences in the preferred temperature and humidity ranges for 
occupants from various climates. The study will leverage the ASHRAE Database II to provide a summary 
of acceptable thermal conditions for different climate zones. This research aims to provide valuable 
insights into the factors affecting thermal comfort, ultimately contributing to the design of comfortable 
and healthy indoor environments for people globally.
