Identifications of models based on time series from field measurements for building simulation 2013 conference

To study the impact variations in input on output vari-ation (Sobol index) of building model, a stochastic model (time series) of variables is introduced. To build the time series we used data measured in a building for each hour for a duration of one month.
The external temperature does not appear directly in the model but affects all the input. So after model it as Auto-Regressive process we propose to model input, for example the heating flux, by an ARMAX process.
