According to DesignBuilder CFD manual, exeternal analysis can be used to calculate more accurate pressure coefficients for EnergyPlus calculated natural
ventilation simulations. However, it is not clear to me how I can get the resulted Cp coefficients (in other words, I can not find the related results) and import them to the EnergyPlus simulation. |

There are no productivity functions included within DesignBuilder to facilitate this process at the moment. So you would need to run 6 or so external CFD simulations, one for each of the wind directions referred to in the Cp data. Then for each surface you would have to calculate the pressure coefficient. It's not a very fast process but users have done it in the past.
