A simulation program (ACRISIM) running on personal computers was developed to study the transient behavior of the thermal microenvironment inside swine buildings housing pigs weighing from 20 kg (44 lb) to 100 kg (220 lb). The program accounts for a large number of parameters including the orientation and the structure of the building, the ventilation rates used and their staging with respect to inside temperature, the existence or not of a pit, and the pig metabolic heat and manure production. It accepts hourly climatic data, incorporates a library with various properties of insulation and structural materials, and uses pull-down menus. Results are presented in tables, shown at the screen, or printed. The program can be used to predict the thermal microenvironment conditions in the building along with the heating/cooling load required to keep the temperature within pigs' thermoneutral zone. Furthermore, it can be used to study the effects that various parameters have on the inside thermal conditions.
