Fabric
Buildings Have More Air Volume
In fabric covered buildings, the high ceiling and larger volume of
air allows the warm air to rise to the peak of the buildings,
keeping the ground surface cooler. Warmer air also
typically contains odors from animals and as it rises, in properly vented fabric buildings, it will be vented
out of the buildings.
If livestock are housed in fabric buildings, adjustable
openings on the sides of the structure such as curtain walls
and exhaust walls like chimneys or open ridges should be
considered. Steel buildings, with
their low roof slope, have a comparably smaller volume of
air in the building. As a result, as the air warms and
rises, it is trapped making it hot and stuffy inside the
steel building. A steel building would
need to be constructed twice as tall to enclose the same
volume of air. This would further add to the cost for
additional leg and sidewall materials.
"Because the roof is so
much higher than a conventional barn, we have a large volume
of air over the cattle. We were able to design the barn to
get all the natural ventilation we need. The air always
smells good in our barns."
