The geographical location and associated climate has a significant influence on greenhouse climate and energy consumption, especially if the greenhouse is not properly designed or managed. The outdoor temperature affects the energy needed for heating or cooling the greenhouse. The outdoor humidity can make it very diffucult to control the humidity inside the greenhouse, which can be problematic for plants that are sensitive to high humidity. Wind can affect the temperature inside a greenhouse by increasing heat loss through convection. This can be especially problematic if the greenhouse is poorly insulated or not properly sealed. At last, the availibity and intensity of natural light has a huge impact on the additional heating and cooling, as well as the potential crop production. Also the location determines the path (angle) of the sun and with this the light transmission of the greenhouse.
In the figure below the monthly average climate of 5 locations with a very different climate is shown, in context of the need for heating cooling and arfificial illumination.
