Air leakage and ventilation effectiveness for confinement livestock housing
With new building materials and construction technology, infiltration still contributed a large portion (about 47%) of the minimum ventilation in swine buildings. This ventilation can significantly reduce the ventilation effectiveness and may even cause failure to control the indoor environment. Infiltration through a building envelope is analogous to an electrical circuit. Similar to the insulation value (RSI), air leakage resistance (RL) could be a standard parameter to express the building material, construction, and performance during building commissioning.
