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, …)

so, the thermal comfort is a way to

determine a person's level of

comfort

Thankyou!
