Table 1: Domains of livestock production that have a mutual relation with climate control and scientific works from literature—with publication year and type of source—that highlight that mutual relation. Figure 2 highlights a strong relation between climate control and air emissions. Ventilation has a dual role in controlling the pollutant concentration and in affecting their emission rates. The same ventilation--type and airflow rate--can modify emission patterns. For example, the NH\({}_{3}\) emission process is enhanced when turbulence--air velocity--and temperature increase above manure surfaces. By contrast, high ventilation flow rates may reduce the humidity of litter inside livestock houses, thus reducing potential emissions in subsequent phases. This mutual relation and the real effect of ventilation, hence, is however difficult to predict since it depends on factors such as the airflow rate, building geometry and manure management system. Furthermore, it may be affected by other environmental parameters, such as temperature and relative humidity. These are relevant topics which need further research to be understood with the aim of improving emission abatement techniques. Climate control also has a mutual relation with productivity and with health. The former relation--with productivity--is because inadequate indoor climate conditions can jeopardize farm production from the quantitative and the qualitative point of view. The latter relation--with health--is because climate control maintains adequate thermal and gaseous environments that contribute to assured hygienic conditions and, hence, to reduction in health risks for both animals and humans.
