New Deliverable: Performance gap causation - D3.2
This report takes the Energy Performance Certificate (EPC) methodologies of nine different European countries, across 65 tested buildings, to investigate how the modelled energy consumption compares with real, measured energy consumption of those same buildings.
Each individual building is modelled with the local EPC methodology and compared with metered energy consumption, converting the EPC output to a parameter that allows for this comparison where required. The study demonstrates the challenges in comparing different methodologies, with different metrics and frameworks, particularly across relatively small samples of buildings.
