 Indoor Air Quality


BRANZIAQ is really an aspirational technical goal for the programme.

It started life in a previous program, where we proved the concept of coupling CFD software with energy simulation software. By combining the two, we can get a more realistic simulation of what is happening in the indoor environment of a building - adequate detail for the flow field within the room that reflects the change in boundary conditions.

We aim to continue this coupling process in WAVE and incorporate the models from the rest of the program so that we are able to:

  • look at the interaction with the actual structure - the effect of having wet walls
  • analyse the effect of putting in an IAQ device such as a PCO chamber
  • incorporate the effect of ventilation systems in terms of moisture removal.
