I am modelling a 60 000 m2 hospital using Design Builder. Unfortunately, the simulation of the whole building is extremely long, requiring up to a whole week. As a solution to this issue, it was thought to divide the building in several smaller parts (one for each floor) using adiabatic surfaces where another floor should have been. The results would then be summed at the end of the simulations. Is this an acceptable Exceptional Calculation Method? If not do you have any suggestion on how to speed the simulation up?
Thank you in advance.
