DESCRIPTION
Group 4 project on building a greenhouse at RCNUWC
Citation preview
Does RCNUWC wants to ¤ live up the Ecovillage dream?
¤ discourage factory farming? ¤ encourage subsistence farming?
If YES....Then Munty, Yasas and Modestas presents....
The Greenhouse
How does the green house work?
The sun radiation (infrared, ultraviolet and visible light) goes inside the green house
Reflection from the surfaceInfrared does not escapeIncreases the temperature
moisture• Plants can be grown
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
ACKNOWLEDGING THAT:
• VEGETATION OF CUCUMBER, TOMATO AND SALAD PLANTS TAKES 60 DAYS• HARVEST CAN BE TAKEN 5 TIMES PER YEAR
•40 KG OF VEGETABLES ARE USED TO PREPARE FOOD BY KANTINA• TOTAL MASS OF REQUIRED VEGETABLES PER YEAR WOULD BE 14 ,400 KG• EACH HARVEST IS EXPECTED TO PRODUCE 2 ,880 KG• MASS YIELD OF TOMATOES AND CUCUMBERS APPROXIMATELY ARE 10 KG*M - 2
• EFFECTIVE AREA OF THE GREENHOUSE IS 2888 /10 = 300 M 2
• ADDITIONAL AREA = 100 M 2 (FOR PATHS, EQUIPMENT, DRAINAGE)• TOTAL AREA = 400 M 2
What is the area of a greenhouse?
WE DID A RESEARCH AROUND THE SCHOOL PREMISES TO FIND A SUITABLE PLACE TO
ESTABLISH THE GREEN HOUSE.
The Location For A Green House
Things we considered
The size of the placeDoes it have the access to resources (water,
transport and electricity)Ownership of the land
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
Is there enough space?
Energy for the green
house
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 waterfallsDuring the summer the green house relies on
heat and light produced by sun radiation
The places to establish the power plant.
The little water falls around the campus.
There is quite big one in front of the Haugland
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.
What is the price of the Green House?
•Price per 1 m2 is 890 NOK•Price per 400 m2 is 350,000 NOK
This fantastic offer includes modern irrigation and light systems.
