Identification and inversion of gas transport processes in buildings

An approach for estimating the strength of a gas source in an enclosure is described. The approach is based on a lumped-parameter model of the component gas transport dynamics and a priori information regarding the process parameters and input. Parametric uncertainty is handled by estimating the unknown process parameters along with the source strength. Simulations and experimental results of a scalar process are included to demonstrate the efficacy of the approach. Potential applications include lighting, ventilation, and temperature control in building.
