We present a technique for performing system identifica tion in climatic model for a livestock building partitioned into zones. The dynamic model for livestock building cli mate takes into account possible leakages in the building envelope, and is both nonlinear and hybrid. The proposed technique is based on a novel idea of having well defined internal flow directions during data acquisition, which turns out to give a simple construction of the signal vector. Fi nally the obtained model parameters remain valid for arbi trary internal flow directions. We present the outcome of using the technique on a real life data set, and conclude with guidelines for further enhancements of the proposed method.
