IDA ICE 5: New methods improve atrium studies

To study and understand the behavior of an atrium is difficult, especially if you want to look at periods of poor climate conditions, and not just the extremes. Traditional, well-mixed zone models are way too simple, and traditional CFD solutions are too expensive for dynamic studies in everyday project work. Also, real buildings are never in steady-state (a common assumption for CFD studies.)

Two new methods in IDA ICE 5 aim to improve these studies: a detailed new zone model and a smart integration between IDA ICE and OpenFOAM® CFD.

The new zone model, which is based on flow elements, allows for detailed indoor climate analysis with dynamic results visualized in a 3D-grid (PPD, PMV, operative temperature, air temperature, air velocity, draught, CO2).

The integration between IDA ICE and OpenFOAM® allows for easy and accurate setup of a CFD model, with boundary conditions coming directly from an IDA ICE simulation, thereby capturing the true dynamic nature of a building.
