Air movement in a naturally-ventilated room can be induced through the use of a solar chimney or Trombe wall. In this work Trombe walls were studied for summer cooling of buildings. Ventilation rates resulting from natural cooling were predicted using the CFD (computational fluid dynamics) technique. The renoramlization group ( RNG) k-e turbulence model was used for the prediction of buoyant air flow and flow rate in enclosures with Trombe wall geometries.

Gives an overview of current developments into passive ventilation technologies within office buildings and their impact on current ventilation practices. Covers prevention of heat gains, modulation of heat gains, and heat dissipation.
