Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment and is assessed by subjective evaluation (ANSI/ASHRAE Standard 55). The human body can be viewed as a heat engine where food is the input energy. Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment and is assessed by subjective evaluation. The human body can be viewed as a heat engine where food is the input energy. The human body will generate excess heat into the environment, so the body can continue to operate Thermal comfort is important for health and well-being as well as productivity. ... As you may guess, thermal comfort has to do with more than the temperature. It can be achieved only when the air temperature, humidity and the movement of the air are in proper balance with each other.

1. Thermal comfort
Thermal comfort means conditions in which
the person is satisfied with the thermal
conditions
In practise: The person can not say whether
he would prefer warmer or cooler environment
The core temperature of the body should be
36-38 ºC, although the temperature of the
environment would have great variations
The body core temperature can be measured with a
thermometer
The skin temperature may vary more
= energy gained from metabolism
= work accomplished
= evaporation exchange
= radiant exchange
= convection exchange
= conductive exchange
= heat energy stored in the body
