Asparagus is an agricultural produce containing high nutrients commonly encountered on the dining table. In order to maintain the yield of asparagus, young farmers use a net house to increase the output of asparagus in winter and reduce the losses caused by heavy rain and high winds. Although the yield is increased in winter, the design of the net house in summer results in poor quality of asparagus due to high heat. For this reason, a team headed by professor Tzu-ping Lin of the department of architecture assisted the Banana’s Asparagus farm. This team’s goal is raising the crop’s quality in the net house during summer, and maintaining its output in winter through a novel environmental control technology with an affordable budget.
