Literature Review of Uncertainty of Analysis Methods, (DOE-2 Program), Report to the Texas Commission on Environmental Quality
MetadataShow full item record
This literature review covers the DOE-2 simulation program, which is one of the legacy programs in the ESL’s Emissions Calculator (eCalc), a web-based emissions reductions calculator. The eCalc program is a tool for those who want to see how their energy savings have reduced NOx emissions, which are produced by on-site combustion of natural gas, or at fossil-fuel burning power plants that supply the electricity. This report includes a brief history of the development of the DOE-2 program, and includes an analysis of the reported accuracies of the DOE-2 program. For the validation of the DOE-2 program, peer-reviewed literature that presented case studies using one of three methodologies (empirical, comparative, or analytical) were reviewed and summarized.
DescriptionThis report reviews the reported uncertainty of the DOE-2 simulation program by reviewing the published accuracy of DOE-2 simulations versus: measured data (Empirical Validation), other simulation methods (Comparative Test), and analytical calculation (Analytical Verification). This report includes a review of the history of the DOE-2 simulation program. In summary, from the literature it was found that DOE-2 simulations versus measured data were shown to vary by 10% (reported in 33 of 47 studies) to 26% (reported in 14 of 47 studies). DOE-2 simulations versus simulations by other programs showed agreement in the 1% to 30% range, and from 1% to 15% when weighted by building size. DOE-2 predictions of whole-building energy use versus analytical calculations were shown to vary from 0% to 5%. One report that focused on component modeling showed that DOE-2 versus analytical calculations varied from 0.2% to 18.7%.
