Title: Wind induced natural ventilation of low-rise buildings for livestock housing by the pressure difference method and concentration decay method.
Author: Choinière, Yves.
Abstract: Measurements of the external pressure coefficients around open and sealed 1:20 scale models of a low-rise, naturally ventilated building with a gable roof for livestock housing were made in the NRCC wind tunnel. In addition, the internal pressure coefficients were recorded within the open models. All structural configuration changes of the building had an effect on: the external pressure coefficient distributions, calculated and measured internal pressure coefficients, air inlet and outlet zones, magnitude of the local airflows through individual openings, and on the calculated ventilation rate coefficients. As well, there were considerable differences between results for the sealed and open models especially at the ridge level. Generally, the comparisons between the ventilation rate coefficients of the open and sealed model suggest that the larger the total sidewall, end wall and ridge opening areas were, the greater the discrepancies were between open and sealed models' predictions.
