The environment in and around livestock houses is influenced to a large extent by its ventilation and ventilation control. Additional control parameters (animal activity and CO₂ indoor concentration) as well as adiabatic air cooling were integrated into newly-developed ventilation control concepts and randomly investigated during four fattening periods. Measurements included temperature, humidity, ventilation rate, CO₂, NH₃, airborne particles (different size fractions), and bioaerosols. A high correlation between the animal activity and the indoor particulate matter concentration of PM₁₀ (aerosols with an upper particle size limit of 10Î¼m) was especially found at the ad libitum feeding system. Using the CO₂ controlled ventilation strategy, a reduction of the ventilation rate of 20 % at low outside temperatures was measured, with only minor effects on the indoor air quality. The main influences on indoor air quality as well as on emission of NH₃ and aerosol particles were due to season and water fogging.
