A climate battery greenhouse is an energy-efficient structure designed for year-round plant cultivation. It uses a system of underground air ducts and thermal mass storage to regulate temperature and humidity, reducing the need for external heating or cooling systems. This sustainable approach helps create a stable and ideal environment for plant growth while minimizing energy consumption and greenhouse gas emissions. Greenhouses, in most climates, typically generate way more heat than they can immediately use. As a result, the excess heat is often vented to the outside to avoid injuring plants. In a climate battery system, excess heat is transferred to the floor beneath the greenhouse where it is "stored" for later use. The storage and transfer of this heat is typically accomplished by burying corrugated perforated tubing beneath the greenhouse structure and running a fan to push air through the tubing. During the day, warm (and typically moist) air is pushed underground, where it (ideally) condenses and releases heat, coming out the other end of the tube cooled and possibly at a lower humidity. At night, when heating may be needed, fans push colder air underground to pick up heat and release it into the structure.
