Thermo-energetic simulation in openmodelica and energyplus: Test case from standard VDI 2078

In this work, the test case 1 of german standard VDI 2078 is used to compare softwares OpenModelica and EnergyPlus. The mentioned provides calculation methods thermal load temperature cases for validation zones’ models. This case’s behavior was evaluated in both softwares, keeping reference values provided by standard. Pearson’s correlation coefficient calculated between obtained EnergyPlus zone air temperature, operative type M are, respectively, 0,98 (very strong correlation), 0,87 (strong correlation) 0,99 correlation). Among reasons deviations results from programs are method resistances capacitances radiative coefficient, as well treatment zone’s internal mass.
