Zhoulun,<br><br>I tottally agree with you, even though I still think that CFD calculations can be very useful in early and detailing stages of design (in terms of natural ventilation, air pressure and HVAC insuflation).<br>
<br>What I usually do to consider thermal aspects of ventilation in the energy model is to calculate heat losses due to natural ventilation and air changes per hour (I leave in Brazil so...is pretty hot here most time of the year) in DesignBuilder. However I think you are mentioning something more sophisticated than that.<br>
<br>In terms of time requirements for these simulations...well that's a problem, because in design you usually need quick answers to your problems. However, I still think that this time can be reduced if the models are effectively simplified in order to overcome specific design dilemmas.<br>
