Greenhouses are marvelous devices, allowing one to enjoy the flower spectacle of summer all year round. At night, greenhouses use supplemental heat to keep the fragile plants warm. Over the last 30 years, greenhouse technology has undergone many changes, with the structures being automated and monitored and low-cost plastic structures emerging as a serious challenge to traditional glass greenhouse designs. Low-cost greenhouses use plastic sheeting instead of expensive glass and also employ various energy-saving devices to keep the heat of the day retained as much as possible at night, using only a fraction of the supplemental heat. This article presents a dynamic greenhouse design challenge which is about developing an idea for a new type of greenhouse, one that opens (perhaps like a flower or some sort of opening structure) and closes at night--effectively increasing the volume of plants under protective cover at night, through an efficient packing process.
