Simulation of a complex wind and buoyancy driven building

The majority of design studies on naturally ventilated that wind power is expected to provide a significant or mechanically ventilated buildings do not take component of the motive force for the ventilation account of the close relationship between ventilation system. and thermal performance. That is it is common to assume that certain ventilation rates can be achieved and then used as input to a dynamic thermal model to assess temperatures within the building. In reality the two are closely linked and this paper seeks to demonstrate the feasibility of combining the two processes within a single analytical tool used within a leading UK consulting engineering practice. Furthermore it is recognised that controls cannot be ignored and so the modelling includes a representation of a rule based control system.
