| Abstract:
Since 1973, intensive research has been carried out to reduce energy costs for greenhouse heating. A lot of efforts have been done in the Agricultural Research Center of Northern Greece in order to investigate the possibilities of using others sources of energy on the purpose of reducing the high cost of heating, of which the passive solar system.
