Flipping conventional exhaust fan practices on their head, Gordie Jones, a veterinarian and nutritionist, designed a way to blow fresh air in providing benefits year-round. His concept is, what he calls an “all-season, hybrid barn,” uses positive ventilation when it is needed to boost air flow in a naturally ventilated barn.

- To allow natural ventilation to occur most days of the year.
- To provide consistent air flow, and no dead spots or bunching of cows, through the entire building when heat stress occurs.
- To prevent manure from freezing to alleyways in winter.
