A vertically integrated multilevel closed ecosystem greenhouse for polyculture of a large variety of plants is provided. The structure of the greenhouse is designed with any combination of ellipsoidal, pyramidal, conical or rectangular geometry to allow maximum solar radiation and energy capture. A variety of geometries are used in an optimal manner to simplify construction of the multilevel building. The building is designed with double shell translucent walls to allow cooling and heating with natural and forced convection by drawing air between the two shells. The two transparent shells are separated by a relatively large gap to allow passive sun-driven cooling and heating of the overall structure. The inner greenhouse building, where plants are growing, is a closed space that allows accurate control of all environmental variables and in particular temperature, humidity and CO2 concentration and for the prevention of contaminants in the culture area. The inner shell is a multilevel greenhouse that can be scaled to contain from one to any number of levels depending on the overall building size selected for a certain site. This embodiment allows passive solar heating and cooling of the lower shell greenhouse and contribute to a highly energy efficient structure. The concept of the optimized geometry allowing natural and forced updraft to occur in the relatively large gap between the two shells of the building is part of this invention. |
