What is green house concept?
A greenhouse (also called a glasshouse) is a building where plants are grown. A greenhouse is a structure with a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming visible solar radiation from the sun is absorbed by plants, soil, and other things inside the building.
What are the common greenhouse designs?
Common design styles include lean-to, even-span, uneven-span, ridge-and-furrow, retractable-roof, and shadehouse. Many of the tasks that support the production of greenhouse crops take place in a structure attached to the greenhouse known as a headhouse.
What are the design criteria of greenhouse?
The greenhouse must be airtight, to prevent night cooling in those climates in which low night temperatures are expected, as well as to prevent undesirable leakage of CO. A proper ventilation system is needed, with airtight vents. The entrance of water from rainfall must be avoided.
What is the most frequently used greenhouse building design?
The gothic shape is the most popular today as it sheds snow easier than the hoop shape. The square foot cost of a free-standing greenhouse is usually less than a gutter-connected house.
What is modern greenhouse?
The modern greenhouse is usually a glass- or plastic-enclosed framed structure that is used for the production of fruits, vegetables, flowers, and any other plants that require special conditions of temperature.
What are the different types of greenhouses?
Generally speaking, there are three types of greenhouses: lean-to, detached, and ridge and furrow or gutter connected (Figure 1). Few lean-to greenhouses are used for commercial production because of limitations in size. This type of house is the most popular among hobbyists.

What is important of greenhouse?
‘Greenhouse gases’ are crucial to keeping our planet at a suitable temperature for life. Without the natural greenhouse effect, the heat emitted by the Earth would simply pass outwards from the Earth’s surface into space and the Earth would have an average temperature of about -20°C.
What do you need to know about greenhouse design?
The term “greenhouse design” includes too many aspects to be covered in one paper, therefore, this paper mainly addresses developments related to possible effects of manipulations of structure and cover materials on microclimate; it also emphasizes the main concepts and trends in greenhouse horticulture that emerged during the last decade.
What are the dimensions of a glasshouse greenhouse?
Two key designs are used: the narr ow Venlo glasshouse, which is the dominant is favored in the produc tion of cut flowers and potted plan ts. The standard span widths are 3.2, 4, 6.4, 8, 9.6, 12, 12.8 and 16 m.
What are the driving forces for greenhouse design?
The major driving forces toward improving greenhouse design have sprung from the desire to achieve a sustainable greenhouse that is energy neutral, consumes only the essential amount of water, and has minimal negative environmental impact – all while maximizing net financial return.
Which is the best shape for a greenhouse?
Greenhouse experts suggest that the shape and size may affect plant growth. The smaller your greenhouse is, the more limited space your crops have. Still, there’s no best shape. The most important thing is to love the design you choose. A greenhouse is a long- term commitment.
