Abstract: We have reported on the SHASE test procedure developed by the authors for evaluation of building energy simulation tools at the earlier BS2017 and BS2019 conferences (Ono et al., 2017 and Ono et al., 2019). In these reports, we showed that trial simulation results for the expanded set of test cases indicate some discrepancies in energy consumption between tools as well as among test participants. We have investigated the causes of these discrepancies and found that they are due to faults in tool programming, participant errors and misunderstandings in inputting parameters of equipment performance, control logic, and so on. Therefore, we decided to add several subsystem tests to overcome these problems and found that comparing the results of these tests qualitatively and quantitatively in step-by-step analysis assists in identifying the problems.
