ABSTRACT:
To improve heat economy in certain building structures, e.g. greenhouses and sports halls, a plastic film is applied which is held in place by evacuating the space between the structure and the plastic film. Periodic excess heat is accumulated in a heat storage chamber, which can also be combined with a composting chamber.
The building structure is preferably made in the shape of a geodesic dome. Greenhouses of this type can be placed with advantage on pontoons or barges.
