Many blueberry farmers use an open-sided hoop-type greenhouse to enhance agricultural output. A common problem in multi-span greenhouses is the loss of ventilation that scales with the increase in span number. This paper examines the effects of reducing the greenhouse height and adding covers to the formerly open sides in a two-span greenhouse to understand better flow characteristics that may contribute to energy loss. It concludes that lowered height can create a more even temperature distribution, while side covers make the flow direction more predictable but decrease flow speed and increase internal temperature. This paper recommends adding side covers with controllable height to the greenhouse to increase the temperature during cooler periods of the day.
