To predict indoor climate in pig houses, design and management conditions have to be taken into account. Heat loads are high, and vary with live weight and animal production. Ambient air is often supplied directly into the room without preheating. Variable temperature set points are widely used to provide a warmer environment for young than for older pigs. Temperature control is maintained by supplying variable airflow rates, and minimum ventilation is limited by CO2 or humidity control.
