As we all know, the most developed agricultural greenhouse in the world belongs to the fully automatic glass greenhouses in the Netherlands. However, the Netherlands has an oceanic climate. It is not cold in winter and not hot in summer. The annual climate is between -5 and 30 degrees Celsius. The climate is relatively mild throughout the year, but the light environment is weak in winter. Therefore, in the greenhouse structure type, we choose the patterned all-glass greenhouse cover. The glass has the highest light transmittance, and the light transmittance of the coated glass can reach up to 97%. At the same time, the Dutch glass greenhouse does not have an external shading system and does not need to consider the use of fan water curtains, so the construction area can be unlimitedly expanded without restriction. However, in some tropical places, it will face the problem of cooling in summer, and it will face the problem of heat preservation in winter when used in the frigid zone.

Because we improved the patterned glass greenhouse by installing an external shading system, increasing the area of the ventilation window on the top, and installing a fan and water curtain system to solve the problem of cooling.

For glass greenhouses in cold areas, internal insulation systems, wall insulation systems, and internal heating system equipment need to be added.
