Study of a methodology for measuring the energy efficiency of buildings

Context and objectives

The internship, led by Florent Cornet at MINES ParisTech and supervised by Patrick Schalbart, aims to achieve in situ measurement of the determinants of the energy efficiency of buildings, for example the Heat Loss Coefficient or HLC. It concerns rehabilitated or new buildings, as part of an approach that brings value to the various stakeholders while offering sufficient conditions of reliability with limited technical constraints at an acceptable cost.

An analysis of existing methods was carried out in order to identify the advantages and potential limitations of use, and to explain their level of complexity. Systematically, the biases and the robustness of each method have been described according to several constructive typologies.

House considered for the case study (INCAS platform in Chambéry).Results obtained by 5 measurement methods over 3 periods and comparison with the theoretical reference value of the thermal Heat Loss Coefficient of the house.
