Faced with an increasingly difficult context for production in heated greenhouses, the Ctifl acquired a new experimental greenhouse in 2009 as part of the Greenhouse Energy Sensor project. The objective of the project is to reduce the energy consumption of greenhouses. Several areas of research are being explored: testing a double thermal screen, an inflatable double-wall greenhouse made of F-Clean® to replace a glass greenhouse, industrial dehumidifiers to manage humidity, air/water exchangers for heating, cooling and dehumidifying as well as thermal storage in aquifers.
