The present invention relates to a greenhouse comprising outside walls provided with translucent surfaces ( 2 ) such that light may be received into the greenhouse ( 3 ) from at least two geographical directions, a roof structure ( 7 ) and a roof ( 6 ) provided with an insulating material portion. The invention is characterized in that the outside walls, in connection with the translucent surfaces ( 2 ), are provided with a light reflecting yard structure which resides below the translucent surfaces ( 2 ), above a ground surface ( 50 ), and extending away from the outside wall. The greenhouse ( 3 ) may further comprise vertically positioned light reflecting surface elements ( 40 ) and light reflecting shade elements ( 44 ) movable in a direction parallel with the transparent surfaces ( 2 ).
1. A greenhouse for year-round usage comprising
outside walls,
a roof structure,
a fixed roof provided with an insulating material portion,
the outside walls being provided with translucent surfaces such that light may be received into the greenhouse from at least two geographic directions,
light reflecting surfaces being provided in connection with the translucent surfaces on the outside walls,
wherein the light reflecting surfaces are positioned below the translucent surfaces on a ground surface, such that the light reflecting surfaces extend away from the outside wall, said light reflecting surfaces being arranged to extend from the outside wall in a direction advancing downwardly in an inclined manner, thus forming a part of a yard solution surrounding the greenhouse, the downwardly inclined direction of one of said light reflecting surfaces is towards the south 0 to 10 degrees and the downwardly inclined direction of another of said light reflecting surfaces is towards the east 5 to 15 degrees or the west 5 to 15 degrees, and
the light reflecting surfaces are made from metal plates.
2. The greenhouse as claimed in claim 1 , wherein the light reflecting surfaces extend away from the outside wall by a length which is 1.5 to 2 times greater than a height of the translucent surfaces.
3. The greenhouse as claimed in claim 2 , comprising at least three light reflecting surfaces wherein the downwards inclined direction is towards the south 0 to 10 degrees and towards the east and the west 5 to 15 degrees.
4. The greenhouse as claimed in claim 3 , wherein the downwards inclined direction of the light reflecting surfaces is towards the south 0 to 5 degrees and towards the east and the west 8 to 12 degrees.
5. The greenhouse as claimed in claim 1 , comprising at least three light reflecting surfaces and wherein the downwards inclined direction is towards the south 0 to 10 degrees and towards the east and the west 5 to 15 degrees.
6. The greenhouse as claimed in claim 5 , wherein the downwards inclined direction of the light reflecting surfaces is towards the south 0 to 5 degrees and towards the east and the west 8 to 12 degrees.
7. The greenhouse as claimed in claim 1 , wherein the greenhouse comprises vertically positioned light reflecting surface elements.
8. The greenhouse as claimed in claim 7 , wherein the vertically positioned light reflecting surface elements are pivotally fastened to the outside wall such that the light reflecting surface elements may be turned to protrude in different directions from the outside wall.
9. The greenhouse as claimed in claim 8 , wherein the vertically positioned surface elements are turned by a motor.
10. The greenhouse as claimed in claim 1 , wherein the greenhouse comprises light reflecting shade elements movable in a direction parallel to the translucent surfaces.
11. The greenhouse as claimed in claim 1 , wherein the metal plates are stainless steel plates.
12. The greenhouse as claimed in claim 11 , wherein the light reflecting surfaces extend away from the outside wall by a length which is 1.5 to 2 times greater than a height of the translucent surfaces.
13. The greenhouse as claimed in claim 12 , wherein the downwards inclined direction of the light reflecting surfaces is towards the south 0 to 5 and towards the east and the west 8 to 12 degrees.
14. The greenhouse as claimed in claim 11 , wherein the downwards inclined direction of the light reflecting surfaces is towards the south 0 to 5 and towards the east and the west 8 to 12 degrees.
15. The greenhouse as claimed in claim 11 , wherein the greenhouse comprises vertically positioned light reflecting surface elements.
16. The greenhouse as claimed in claim 15 , wherein the vertically positioned light reflecting surface elements are pivotally fastened to the outside wall such that the light reflecting surface elements may be turned to protrude in different directions from the outside wall.
17. The greenhouse as claimed in claim 16 , wherein the vertically positioned surface elements are turned by a motor.
18. The greenhouse as claimed in claim 11 , wherein the greenhouse comprises light reflecting shade elements movable in a direction parallel to the translucent surfaces.
