Gas emissions from livestock are subject to strong diurnal and short term fluctuations, which cause several emission peaks over the day. One main influencing factor is the variation of the ventilation rate, which commonly is mainly temperature controlled in mechanically ventilated livestock buildings. Concluding from known relations between the emissions and ventilation, a possibility is seen to reduce the mean gas emissions from a pig house by cutting emission peaks which occur because of animal activity, feeding and day-night rhythms. In the scope of a research project at a pig facility special emphasise is laid on the development and test of several innovative ventilation control systems which go hand in hand with a verifiable emission reduction and an animal acceptable indoor air quality.
