Natural ventilation can reduce cooling needs and add to human comfort. Natural ventilation performs one basic function - supplying fresh air. Cool air rises, so intake air into the structure from as high as possible. The more massive the building material, the longer it retains heat. It is best to vent air out of a structure at the highest point possible.
Winter winds can remove a large amount of heat from the dwelling.
In Louisiana, the strongest winds are in the summer months. Buildings should be well sealed and insulated in order to prevent heat loss. Natural Louisiana Architecture. Cazayoux, Hebert and Winn. Natural Louisiana Architecture.
