Activity C.7: Feasibility of using geothermal energy as heat and humidity control for an organic greenhouse tomato crop

Objectives:

The general objective of this research activity is to evaluate the economic feasibility and the performance of a (semi) closed greenhouse under nordic (northern) conditions in the east of Canada by the use of geothermal and heat exchangers.  This innovative concept will permit:

• Achieving an optimal control of the temperature and humidity in the greenhouse throughout the production season.
• Increasing the CO₂ concentration in the greenhouse during the period of strong solar radiation and as a consequence, the fruit output.
• Reduce the use of fossil fuels and increase the efficacy of energy utilisation (EUE) of the growing.
• Reduce the environmental imprint connected to greenhouse growing.
