Natural ventilation - its role and application in the bio-climatic system.

Discusses the mechanisms of natural ventilation. Gives equations for stack effect and ventilation due to wind. Discusses use of natural ventilation in livestock buildings. Shows how minimum and maximum ventilation rates for winter housed cattle can be calculated using physiological data and a model for calculating the critical temperatures. Gives sample calculation of the ventilation rate necessary for beef cattle housed in a 9m. wide building.
