Investigation of the correlation of building energy use intensity estimated by six building performance simulation tools

The statistical analysis of the collected data revealed that heating EUI conversion formulas were more robust than those of cooling EUIs, and a project case generating moderate or high EUIs generated lower error rates than that with low EUIs. Since building energy performance always generates significant discrepancies, depending on the simulation tools adopted, the outcome of this study will help building performance stakeholders understand the estimated energy performance of one tool as compared to that of another. The result will also be helpful for designing a high performance building without a technical mishap.
