Abstract: The aim of this work is to evaluate the reliability of different methods allowing the estimation of global envelope thermal parameters, the heat loss coefficient and the main time constant, using short term monitoring. Energy signature, steady state calculation, and identification methods have been tested on a new experimental passive house. A specific heating scenario was adopted. It consists to create a transient state between a heated period and an unheated one. The possibility of identifying the main time constant and the global heat loss coefficient of the building is evaluated using respectively the transient period and the measurements over the heating period.
