Ventilation Calculator

The new ventilation calculator aims to calculate the minimum size of inlet/outlet to allow heat and moisture produced from the livestock to leave the building by natural convection. Air circulation is crucial for health and welfare in livestock buildings, yet 60-80% of housing in the UK is not adequately ventilated. Good ventilation is about getting sufficient air inlets and outlets for the way the building is being used, whilst taking into account the surrounding topography, prevailing wind direction and any other nearby buildings.

The data within this calculator has been provided by AHDB Dairy.
