Parameter Uncertainty and Performance Gap in Energy Simulation of Transparent Building Envelopes
This study aims to present that the thermal properties of transparent building envelopes, e.g. U-factor and SHGC, need to be treated as dynamic variables. The aforementioned thermal properties have been treated in a deterministic fashion in many simulation studies. To quantify parameter uncertainty caused by U-factor and SHGC, the authors conducted uncertainty and sensitivity analysis for eight different window systems in 17 climate zones. The thermal properties are calculated using “pyWinCalc,” a python module using WINDOW calc engine developed by LBNL. When the dynamic properties are applied in a stochastic manner to a DOE reference medium-size office model, up to 13% of difference is found in monthly averaged heat flux flowing into the indoor space through windows, compared to a prediction out of the deterministic properties.
