Understanding the Factors
Thermal comfort is complex and subjective, but it's influenced by several key environmental and personal factors. This tool uses a simplified model based on the ASHRAE 55 standard to predict how comfortable you might feel.
Temperature
The most obvious factor. We measure it in Celsius.
Clothing (clo)
Clothing provides insulation. A typical business suit is about 1.0 clo. Shorts and a t-shirt are around 0.3-0.5 clo.
Air Movement
Air movement (like from a fan or draft) helps cool the body by increasing heat loss. Measured in meters per second (m/s).
Other factors not included in this simplified model are metabolic rate (are you active or resting?), humidity, and radiant temperature from surfaces like sunny windows or cold walls.
