Sizing Openings for Naturally Ventilated Barns
The recommendations in this leaflet concerning sidewall chimney sizes, as well as building orientation have been developed using Ontario Ministry of Agriculture, Food and Rural Affairs' new computer software for natural ventilation, NatVent 2.0, which provides quick estimates for design of openings. If the recommendations in this leaflet are used to size the sidewall and chimney openings, and to orient the building, then natural ventilation should work very well during the summer. In winter, the automatic control system reduces the effective opening as necessary, to control the ventilation.
