Computer simulation requires theoretical and empirical mathematical relationships describing different aspects of heat and moisture transfer for livestock confinement buildings. Relationships with various degrees of sophistication exists that adequately describe these heat and moisture transfers. Using these relationships with climatic data, environmental requirements, construction characteristics, material properties and economic data, a computer technique can be developed to mathematically model energy requirements for operating confinement livestock environments. This technique should base ventilation rates on moisture removal, temperature control and animal comfort criteria to minimize unnecessary energy consumption. However, no such computer model currently exists that determines and employs optimal ventilation rates in the simulation of the transient heat transfers for livestock systems in specific climatic regions. Therefore a research project was initiated to mathematically simulate energy transfers for confinement livestock housing with the following objectives: 1) Develop a generalized computer program for optimizing environment modification systems in confinement livestock housing. 2) Determine heating, insulation and ventilation recommendations based on climatic conditions and livestock operation systems. 3) Evaluate model performance for selected livestock types, animal densities, degree of environmental control and animal numbers.
