Genetic optimization & natural ventilation

Amongst the team's ongoing research topics: optimizing the modeling of natural ventilation in dynamic thermal simulation.

In order to reduce the computational effort for the pressure coefficient computations by means of CFD simulations, we have to answer the following questions:

"Can we choose the wind directions a priori to limit the number of CFD calculations?"
"With a fixed number of CFD calculations, can we minimize the modeling error compared to a reference case?"

On the agenda : thegenetic optimization coupled to EnergyPlus.

Difference of pressure coefficients on a façade element between the classical approach and the coupled CFD+BES approach.
