When calculating the correct ventilation capacity of your poultry house, naturally, several factors need to be taken into account to lay the basis for a well-functioning livestock ventilation system. In this paper, the most crucial ones are reviewed along with a calculation tool to further address this topic.

Start with the (inside) dimensions of the house itself. The later on determined air speed and air exchange rate are related to, or in other words, are fully dependent on the size of the house.

Secondly, one describes the occupation characteristics: What kind of poultry breed does it concern and what is the highest stocking density in kilograms per square meter during the cycle? For broilers, layers and breeders, different minimum and maximum ventilation rates apply for optimal bird welfare and thus production efficiency. As these ventilation rates are specified in cubic meters of (fresh) air per hour and kilogram bird weight, it is essential to know the total live weight in the house at the start and at the end of the cycle.

Lastly, the climate in which the house is situated heavily determines the maximum ventilation capacity, as an overall warmer climate requires higher air speeds in the house to obtain an adequate wind chill effect. In below image, you can find an example calculation of a broiler house in a mild Sea climate.
