Cross Ventilation

For cross ventilation, air is drawn through the width of the building instead of the length of the building. Cross ventilation allows for the building ends to be used like overhead doors as opposed to fans and pads.

The building must be sealed for cross ventilation to be effective. All roof vents, chimneys, side vents, windows, doors, and openings other than the air inlet area opposite of the fan wall must be closed.

Buildings with open ceilings require baffles to ensure that the air movement maintains the velocity. Baffles should run parallel to the roof line, be equally spaced and hung as low as possible without effecting the daily routine of machinery. The lower the baffle height, the better the velocity at cow level.

Evaporative cooling systems for the air inlet end of tunnel ventilation system are frequently recommended. Air intake is determined by the number of fans.

During winter fewer fans are required to remove gas, keep air fresh, and humidity low. The winter rate should be approximately 50 to 100 cfm per cow.
