Hi everyone,

I would like to simulate the thermal behaviour of a huge room (in a Museum) of around 300m² and 15m height. However, in DesignBuilder you only have one temperature 'sensor' per zone, so it won't take into account the air stratification. For now, I modelled two zones of 7.5m height on top of each other, with a hole between them. I then have different temperatures and thermal interaction between the two of them, but results do not appear as I would have expected, and I wanted to have your opinion on how to model large, high rooms where air stratification will have a big impact.

Thank you everyone!

@PhilippeR could you include screenshots of your model or images/tables of the results that are not expected?

You may consider to model as a single zone and use the "Air Temperature Distribution" option '2-Dynamic gradient' at available at HVAC tab. For more information see DesignBuilder Program Help chapter Air Temperature Distribution
