Energy cost of greenhouses is the major concern in greenhouse management during winter time. Greenhouse energy consumption per day can be reduced by lowering the greenhouse temperature since energy consumption is approximately the liner function of different between inside and outside air temperature of greenhouse. However, Lower greenhouse temperature requires longer growth period. Total energy consumption is the product of these two factors, and is not simply calculated. A greenhouse energy consumption was constructed and was estimated using the developed model in this project.
