Thermal environments refer to the conditions surrounding a system that affect its temperature and thermal comfort, influenced by factors such as air temperature, humidity, and air movement. Understanding thermal environments is crucial for designing energy-efficient buildings and ensuring occupant comfort and productivity.

Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment, influenced by a range of environmental and personal factors. Achieving thermal comfort involves balancing heat gains and losses to maintain a stable core body temperature, accommodating individual preferences and external conditions.
