CFD ASSESSMENTS WIT IN STRONGLY TRANSIENT DOMAINS
Assessments based on CFD snapshots f stable conditions within strongly transient domains do not address many aspects of performance associated with occupant interventions,control actions or changing climate.Such domains (e.g.double skin fa(c)ades)are characterised by transient flow patterns due to changing weather patterns,actuation of dampers intermittent opening f fa(c)ade windows and operation of building environmental systems.Importing boundary conditions from whole building simulation is an improvement but it discounts the impact of the flow predictions on the building domain.A transient approach is suggested which is fully coupled to flow and thermal solvers for the building fabric, environmental control systems and air flow regime. The paper reviews a number f patterns f flow evolution in strongly transient domains in response to changes in ambient conditions,damper actuation, fa(c)ade openings and intermittent flow from mechanical ventilation systems.
