Group 4 project on building a greenhouse at RCNUWC

1. Does RCNUWC wants to ¤ live up the Ecovillage dream? ¤ discourage factory farming? ¤ encourage subsistence farming? If YES.... Then Munty, Yasas and Modestas presents....

2. The Greenhouse

3. How does the green house work? The sun radiation (infrared, ultraviolet and visible light) goes inside the green house Reflection from the surface Infrared does not escape Increases the temperature moisture Plants can be grown

4. What could be grown in the greenhouse? Depends on the temperature, humidity and soil fertility Temperature: 25 – 30 °C C4 plants (high daylight temperatures and humidity) Cucumbers, tomatoes, carrots

6. harvest can be taken 5 times per year

7. 40 kg of vegetables are used to prepare food by Kantina

8. total mass of required vegetables per year would be 14,400 kg

9. each harvest is expected to produce 2,880 kg

10. mass yield of tomatoes and cucumbers approximately are 10 kg*m-2

11. effective area of the greenhouse is 2888/10 = 300 m2

12. additional area = 100 m2 (for paths, equipment, drainage)

14. Things we considered The size of the place Does it have the access to resources (water, transport and electricity) Ownership of the land

16. Is there enough space? Estimated size for the Green house is 400 m². The size of the selected place is 2500 m² we have enough space in that place to build the green house and to do other projects like compost station, irrigation, etc

17. Energy for the green house

18. Energy for the green house A Micro-hydro power station. Energy from falling water. Used to light the green house and provide suitable temperatures for plant growth. The micro-hydro power station produces from 5kW to 100kW which is enough. Summer climate dries waterfalls During the summer the green house relies on heat and light produced by sun radiation

19. The places to establish the power plant. The little water falls around the campus. There is quite big one in front of the Haugland

20. Efficiency of the power plant The green house uses an approximation of 30kw for 2500 hours Power plant produces a considerable amount of greenhouse's heat and electrical needs. This is about a third of the power produced by the small scale hydro-power station. The power station is very efficient in this case.

22. Price per 400 m2 is 350,000 NOKThis fantastic offer includes modern irrigation and light systems.

24. High energy consumption

25. Imported vegetables are cheap and edible

26. Additional projects (HE, compost)+ Fresh vegetables Pioneering amongst other campuses Eco awareness Self sufficiency Green house EAC
