Greenhouse or Green house refers to a limited space that can control the suitable environmental conditions for plant growth from different regions during different seasons of one year.
According to this definition, including greenhouse performance, providing the necessary environmental conditions is a specific product requirement.
Greenhouses are divided into fixed and moving types depending on what type of building materials are used in them.
Fixed greenhouses are greenhouses in which the building materials used are of stable and durable materials. So they should be used for many years.
Greenhouses are used to provide optimal environments for plant growth and development.
The greenhouse design must deal with the local outdoor circumstances, like minimum, maximum and average temperature, humidity, solar radiation, clearness of the sky (clouds), precipitation (rain, hail and snow) and average wind speed and wind direction.
Some of the components of a greenhouse design are location, orientation, site selection, drainage, structure, foundation, flooring, glazing, and ventilation facilities together with the technical equipment needed to control the climate inside the greenhouse.
