Glossary: Cooling Load
**Cooling Load** is the rate at which heat must be removed from a room or building space to maintain a comfortable indoor temperature and humidity level, measured in BTUs per hour (BTU/hr) or kilowatts (kW).
Envelope and Solar Heat Transmission
Calculations must account for envelope heat transmission, solar radiation through windows, internal heat loads (occupants and appliances), and ventilation infiltration requirements.
