Orienting Livestock Shelters to Optimize Natural Summer Ventilation
Using the meteorological data of 10 Ontario weather stations, natural ventilation rates were computed for a typical gable roofed swine shelter, oriented at 6 different angles from the north. A nonparametric statistical procedure was used to identify that orientation giving the least period of ventilation under the required rate, throughout the summer, for temperature ranges above 20° C, 25° C, and 30° C.
