Ventilation by natural convection of a one-storey building.

A study of passive ventilation of a one storey detached building. A hot element of the building, heated by solar energy, induces the air flow. It could be part of a roof or a wall, or a chimney drawing air into the building. No electrical power or mechanical installations are needed, so it is appropriate for use in remote areas and buildings which are not grid-connected. The method can be used to remove toxic gases such as radon. A steady state laboratory model was used for experiments and simulations in steady and transient states. Results showed that it is possible to obtain effective ventilation by the method described here. Presents and discusses numerical simulations for steady and transient ventilation in full scale buildings.
