Integration of Building Energy and Airflow Simulation



  • The indoor air temperature gradient and covective heat transfer from CFD can used in an ES model for more accurate energy calculation.
  • CFD can accurately simulate natural ventilation driven by wind effect and stack effect, that can also be used in ES model.
  • ES can provide more accurate flow and thermal boundary conditions for CFD simulation

CFD can also be exteneded to solve heat transfer in solid material, even with an appropriate radiation model, HVAC system model, and plant model, the extended CFD program can have the functions of both ES and CFD programs. But  it is very eompztationally expensive.
