Building structure and building panel and method of controlling

Abstract

A construction device comprises a panel which may be used for a structural member in either an interior or exterior wall and which has a side with a transparent wall. The transparent wall forms an exposed exterior surface. A chamber is defined behind the exterior surface either directly adjacent it or spaced therefrom. A fluid is positioned in the space and is selected for the characteristic that is to be imparted to the space, for example it may be of a particular color, insulation characteristic, heat transfer characteristic, reflection characteristic, light absorption characteristic, strength characteristic, shielding characteristic either in respect to magnetic, electronic or heat conditions, etc. The arrangement is such that when the fluid is behind the transparent wall it permits the wall to be used for example as a solar panel or as a transparent window panel if desired. In addition the fluid may contain a color which may change the appearance of the wall as visible through the transparent face and in fact many desirable characteristics may be imparted to the surface and these characteristics may be readily changed. By constructing the panel so that it is connected to a pump for circulating the fluid through it the constructional device may be used either as a sun shield or sun heat absorber or it may be used as a decorative interior wall or as an exterior building surface which may have its color characteristic changed regularly.
