HVAC cooling load calculation determines the amount of heat that must be removed from a building to maintain comfortable indoor conditions. By analyzing factors such as solar heat gain, occupants, lighting, equipment, and ventilation, engineers can accurately size HVAC systems for energy efficiency, reliability, and optimal indoor comfort.

Calculating cooling load is essential for designing efficient HVAC systems in commercial buildings. It determines the amount of heat that must be removed to maintain comfortable indoor conditions. By analyzing factors like building envelope, occupants, lighting, equipment, and ventilation, engineers can accurately size air-conditioning systems and improve energy efficiency.
