Design of refurbishment: determining of parameters to be measured to adjust the predicted energy calculation

The purpose of the CEBO research project is to propose a tool to assess the Effective Consumption of Occupied Buildings by calculation, which will be adjusted by measurement parameters that are limited in number and monitoring time. In this paper the method to identify the parameters that have to be measured is presented on a single family housing, using the TH-CE ex model (French regulation model for existing buildings).  The method is based on uncertainty analysis with fractional factorial design. On the single family house test case, it appears that the weather data, then the set point temperature need to be measured.
