Accelerate Simulation with Run-period Split Method

Description of the method

Speed gain

Limitations

1. The initial condition of each split period will not be identical to that at the same timestep during the annual simulation. Hourly values, especially temperatures, at those timesteps show larger errors. This may cause problems to comfort evaluations, especially in the standards such as adaptive comfort and CIBSE TM52/59.

2. Large discrepancy is seen in economics calculations when ratcheting, seasonal or block tariffs are used. This impact on LEED and Life-Cycle Cost analysis etc.
