In building engineering and in the area of thermal environment, various modeling methods advanced to predict either the building energy consumption or airflow and temperature distribution within buildings. These methods are based on the different level of simplifications, the conservation equations used, the accuracy and the applications targeted. A new zonal model POMA+ has been developed to predict temperature and airflow distribution within any room of a building. The main objective of this work is to develop an evaluated and robust zonal model that can be used for building design and thermal analysis. This model has been evaluated by comparison to other models: existing zonal models and experimental data obtained from Minibat experimental chamber. The shuffled complex evolution method, as well as experimental results have been used together to calibrate the new zonal model and improve its prediction. The calibrated model shows a better prediction of airflow, temperature and pressure comparatively to the existing models for all case studies. Finally, multiple error measures have been used to evaluate the quality of the new calibrated model.
