What is Natural Ventilation?
All livestock and poultry buildings require continuous ventilation 365 days of the year to maintain a healthy and productive environment. Since there are so many choices for ventilating a particular building, it is important to consider all the options available.

The ventilation requirements of livestock buildings are the same for either naturally or fan ventilated buildings. Sufficient ventilation is needed in the summer to prevent excessive temperature rise in the room, and in the winter to prevent build up of moisture and gases.

Naturally ventilated buildings depend upon the natural forces of wind and temperature difference (chimney effect) to move air. Wind can blow air through openings in the wall on the windward side of the building, and suck air out of openings on the leeward side and the roof. Temperature differences between warm air inside and cool air outside can cause the air in the room to rise and exit at the ceiling or ridge, and enter via lower openings in the wall. Overall ventilation is due to the combination of the wind and chimney effects.

What are the Advantages to Natural Ventilation?
Some of the advantages to Natural Ventilation are:

85% Reduction in Cost of Electricity
Reduced Dust
Reduced Heating Cost
15 Year Warrantee
Reduced Operating Costs
Reduced Noise Level
Improved Odour and Humidity Control
Ventilation Functions in the Event of a Power Failure
Daylight Brightens Buildings
Summer Ventilation Rates are High

Since there are fewer moving parts to a natural ventilation system, maintenance and related costs are lower than with a fan system.
