A building energy models calibration methodology based on inverse modelling approach

Abstract Nowadays, building energy models (BEMs) are widely used, particularly in the assessment of consumption buildings to address potential savings that can be generated. The realisation a dynamic model based on high-fidelity physics (white-box models) requires tuning process fit reality, due many uncertainties involved. Currently some research trends try reduce this performance gap by modulating different types experimental parameters such as: capacitances or infiltration. EnergyPlus simulation software, its latest versions, has implemented an object: HybridModel:Zone calculates infiltration and internal mass using inverse modelling approach employs only measured indoor temperature data invert heat balance equation for zone under study. main objective paper is execution time development quality generating new calibration methodology implements approach. This uses, as starting point, created authors study, which was empirically comparatively validated against developed participants Annex 58. It also worth highlighting empirical validation object, since it activated all scenarios where possible: periods seven days more free oscillation load. findings promising. generated with methodology, if compared those produced baseline model, improve their resemblance real ones 22.9%. While predecessor did 15.6%. For two dwellings foreseen 58 IEA ECB project have been modelled monitoring used.
