Comparison of Three Methods in Addressing Measurement Uncertain Data for Urban Building Energy Modeling
Urban building energy modeling (UBEM) empowers the construction of low-carbon cities. However, its development is hindered by the uncertainty of data inputs. This paper used thermal parameters of construction assemblies to analyze the impacts of input uncertainty on the accuracy of UBEM with three different approaches, i.e., the archetype, probabilistic model and urban factor approaches. The results showed that the errors of the three methods could reach 500% at the building level, but converged to less than 100% at the district level. In addition, the errors of the archetype method were 4%–8% larger than those of the other two methods. This study emphasizes that improving the accuracy of UBEM requires comprehensive and accurate inputs, and dividing immense computational work into multiple batches has its theoretical basis.
