What is the process of heat gain?

The process of heat gain refers to the addition of heat from various sources to a space. This can occur through a variety of means such as sunlight entering through windows, heat generated by appliances and machinery, and even the body heat of occupants. Understanding heat gain is essential in energy management, as it impacts heating, ventilation, and air conditioning (HVAC) systems and overall energy efficiency in buildings.

The concept is crucial for designing spaces that maintain comfortable temperatures while minimizing energy costs. Properly accounting for heat gain helps in selecting the right size and type of cooling systems needed to maintain a desired indoor climate, especially in environments subjected to significant external heat influences.
