Description: In the past decade, many techniques of systems analysis including mathematical modelling and computer simulation have been applied to the analysis and solution of environmental control problems. Many of these models require major revisions before they may be used to evaluate all design and management factors that influence the environment within total confinement. Only after models have been developed that incorporate the sophistication necessary for systems analysis can they be integrated into an overall agricultural model and applied in the process of farm rationalization. A more sophisticated model to deter mine thermal characteristics of a livestock unit was developed and described by Feddes et al. (1973). They indicated that experience and modification were required to fully evaluate the limitations of the model. The Feddes model was modified to permit prediction of temperatures and humidities as well as interior and exterior surface temperatures as a function of external environment, type of construction and management practices. The revised model then was validated by a comparison between specific measurements recorded in a typical commercial total confinement unit and predicted values generated by the model.
