Recently, there are utilized many simulation-package for dynamic thermal load calculations. It is importance to make clear the computational validation of numerical accuracy. Accuracy of transition matrix for two-node state model was compared between analytical solution and taylor-series method by SAPLO. The result showed the matrix of SAPLO was almost equals the analytical solution. Next, the backward finite difference method and SAPLO was examined in annual load simulation of simplified model. It was found that the room temperature was as same as them. The largest difference of them was found at the heating loads during start-up period.
