Occupants' Perception Towards Thermal Sensation In Engineering Laboratory

Thermal comfort can be defined as a state of mind that expresses satisfaction toward the surrounding thermal environment. European Standard ISO 7730 stated that thermal comfort is a combination of four environmental parameters such as air temperature, relative humidity, air velocity and mean radiant...
