Environmental Comfort Factors
Air temperature (dry bulb – deg F)
Relative humidity (%)
Air speed (ft per min)
Radiant conditions
These factors are controllable through design – a passive system should control all four factors; an active (HVAC) system is expected tocontrol the first three (with “architecture” controlling the fourth)

Personal Factors Affecting Comfort
Physical
Clothing (specifically its insulation value in “clo”)
Activity level (specifically metabolic heat production in “met”)
Mental
State of mind (experiences, expectations, influences of other conditions, …)

Measuring thermal comfort
1) Amv (actual mean vote)
so, the thermal comfort is a way to
determine a person's level of
comfort
Thankyou!
