Improvement of the thermal behavior of a northern community greenhouse
Due to the difficult access to their territories, Northern Canada’s Inuit have faced major adaptation challenges in recent decades, notably in terms of food and energy. Traditional food from hunting, fishing and gathering activities is increasingly difficult to obtain, while European and Canadian fo...

Due to the difficult access to their territories, Northern Canada’s Inuit have faced major adaptation challenges in recent decades, notably in terms of food and energy. Traditional food from hunting, fishing and gathering activities is increasingly difficult to obtain, while European and Canadian foods brought by air or by sea are increasingly expensive. Culture in greenhouses appears as a solution allowing to improve access to fresh vegetables by reducing the ecological and financial costs linked to the transportation of these.The scientific literature on the physical study of northern greenhouses and energetic data (temperature, electricity consumpion, etc.) is scarce. The first part of this thesis has to do with the pinpointing of northern greenhouses existing in North America and shows that this subject is relatively recent. On the other hand, this literature review revealed that the majority of counted greenhouses are not adapted to a cold climate, hence short growing seasons.The second part of this work focuses on the experimental aspect. Data coming from an instrumentation campaign in a northern greenhouse were analysed to demonstrate the relevance of the establishment of a daily thermal energy storage (TES) system. The dimensioning and construction of this system using air as a coolant fluid and local rocks as storage material are also presented. The instrumentation of the rockbed which stores heat has allowed to study energetical data during charge and discharge phases of the stock.
