Heat gain refers to the increase in thermal energy within a space, resulting from both external and internal sources such as solar radiation, electrical appliances, and human activity. Understanding and managing heat gain is crucial for designing energy-efficient buildings and maintaining thermal comfort indoors.

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.
