BauSim 2020 EQUA Workshop

New methods improve atrium studies

Date: 24 Sep 2020
Time: 15.30

Duration: 75 min

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. Real buildings are never in steady-state. Two new methods in IDA ICE aim to improve these studies; a detailed 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 results visualized in a 3D-grid (air temperature,  air velocity, operative temperature, draught, CO2, PPD, PMV). The integration between IDA ICE and OpenFOAM® allows for far easier setup of a CFD model, with boundary conditions coming directly from an IDA ICE simulation, thereby capturing the true dynamic nature of a building. In this workshop we will present and demonstrate these new methods. The workshop is followed by a Q&A session.


Whole year daylight; window and shading performance

Date: 24 Sep 2020
Time: 15.30
Duration: 75 min

Everybody seems to love a glass building... except possibly those that must live or work in it. Whole-year daylight modelling is required by an increasing number of countries and certification schemes. However, the connection with adequate indoor climate and energy performance is often missed. The upcoming new version of IDA ICE tries to cover both sides of the issue, with new whole-year daylight methods as well as easy-to-use spectral models of glazing and shading, with product databases that are always up to date.


Towards practical large-scale district modelling

Date: 24 Sep 2020
Time: 15.30

Duration: 75 min

With the increasing complexity of district energy systems and their control, both energy suppliers, energy consultants, and perhaps even the “prosumers” themselves will need more comprehensive modelling and simulation methods. Today’s methods are often static or close to static and are operated in a silo approach, with limited dynamic interaction between subsystems. EQUA has the ambition to build the next generation simulation tools for this field. We will present our ideas and hope to get some interesting feedback.
