Definitions

• the present invention relates to apparatus forming a building component, comprising a substantially rigid support frame, a first substantially transparent or translucent flexible sheet attached to said support frame and a second substantially transparent or translucent flexible sheet attached to said frame to define an inflatable element.
• the elements may comprise two or more layers of a plastic foil-like material, such as ETFE (Ethylene Tetra Flouro Ethylene) inflated with relatively low pressure air.
• ETFE Ethylene Tetra Flouro Ethylene
• the ETFE sheet is restrained in its perimeter frame, the frame usually being manufactured from extruded aluminum, which is turn fixed to a support structure.
• the ETFE sheet As the element is inflated, the ETFE sheet is placed under tension and thereby forms a tight drum-like skin.
• ETFE based elements of this type are fixed to a support structure to form a cladding and are used to enclose spaces such as atria or to provide a transparent or translucent roof or facade, often as an alternative to glass.
• an apparatus for forming a building component comprising a substantially rigid frame; a first substantially transparent or translucent flexible sheet attached to said support frame and a second substantially transparent or translucent flexible sheet attached to said frame to define an inflatable element.
• at least one region of flexible photo-voltaic laminate material positioned over one of said flexible sheets such that when inflated and when constructed said photo-photo-voltaic laminate material generates electrical energy and provides a degree of shading under conditions of sunlight.

• FIG. 1 A portion of a building is shown in Figure 1 in which a main load bearing structure that includes cross members 101 , supports elements 102.
• Each element 102 has a rigid support frame arranged to support a first substantially transparent or translucent flexible sheet and a second substantially transparent or translucent flexible sheet so as to define an inflatable element.
• most of a building is constructed using inflatable elements.
• inflatable elements may be used in part of a building, such as for a roof, an atrium or for a facade.
• the example of Figure 1 is constructed from rectilinear elements.
• FIG. 2 An inflated element 102 is shown in Figure 2, consisting of three rectangular ETFE sheets held within a support frame 201. A space between the sheets is inflated via a compressed air inlet 202, thereby maintaining pressure within the sealed element.
• the element is also provided with regions 203 of flexible photo-voltaic laminate material secured to one of the flexible sheets. In this way, when the element has been inflated and the resulting inflated element incorporated within a construction (such as that shown in Figure 1 ).
• the photo-voltaic material generates electrical energy and also provides a degree of shading under conditions of sunlight.
• the regions 203 of photo-voltaic laminate material are shown connected in parallel by electrical connection wire 204.
• electrical conduction cables such as cable 204
• Figure 3 A cross-section of the element shown in Figure 2 is detailed in Figure 3.
• the provision of intermediate sheet 303 enhances the stability of the element and also affects characteristics of the element, such as its ability to transmit light and its thermal properties.
• a first inflatable region 304 is defined between the first sheet 301 and the intermediate sheet 303.
• a second inflatable region 305 is provided, between the intermediate sheet 303 and the second sheet 302.
• the regions receive air under these circumstances via a first inlet 306 (for region 304) and via a second air inlet 307, for the second inflatable region.
• Figure 4 A cross-section of support frame 201 is detailed in Figure 4.
• the frame is fabricated from aluminum extrusions, taking the form of an upper frame component 401 and a lower frame component 402. At their edges, sheets 301 , 302 and 303 are brought together to encapsulate a bead 403. The bead 403 is then held within an extruded edge portion 404, which is itself restrained within the lower frame component 402.
• FIG. 5 An embodiment is shown in Figure 5, in which the first sheet 301 has an upper external surface 501 and an internal surface 502.
• the photo-voltaic laminate 203 is secured directly to the upper surface 501.
• the photo-voltaic laminate 203 is secured directly to the upper surface 501 by means of an adhesive 503.
• FIG. 6 An alternative embodiment is shown in Figure 6 in which, again, the laminate 203 is positioned over the upper surface 501 of the first sheet 301.
• an additional sheet 601 is provided again being substantially transparent or translucent and in particular allowing the transmission of light at frequencies most applicable for the optimum operation of the photo-voltaic laminate 203.
• the additional sheet 601 is larger than the laminate so as to present overhanging edges 602 which are secured to the upper surface 501.
• the additional sheet 601 is secured (by the application of an adhesive for example) to the laminate 202.
• the sheet is not secured to the laminate and the laminate is held in position in a pocket-like manner, such that the laminate is allowed a degree of movement over the upper surface.
• the photo-voltaic elements take the form of separate panels that are supported on the upper surface 501 and spaced away from the edge of the elements. This positioning is preferred so as to reduce the degree of flexing to which the photo-voltaic laminate is subjected. Thus, in a preferred embodiment, the photo-voltaic laminate is not applied near to the corners of the element, where the curvature of the transparent sheets is considerable.
• a factory finished unit 701 includes a conventional photo-voltaic component 702, typically consisting of the photo-voltaic material being encapsulated within layers of EVA.
• a conventional photo-voltaic component 702 typically consisting of the photo-voltaic material being encapsulated within layers of EVA.
• further layers 703 of ETFE are provided to facilitate integration into a top layer 704 by a welding process.
• the photo-voltaic construction 701 may be incorporated within the cushion-like structure itself, either after the fabrication of the cushion or prior to the fabrication of the cushion.
• FIG. 8 An alternative embodiment is illustrated in Figure 8 in which a third top transparent or translucent flexible sheet 801 has been provided which extends over the first flexible sheet 301.
• the element is also provided with a second flexible sheet 302 and an intermediate flexible sheet
• a space is provided between the first flexible sheet 301 and the additional third sheet 801 configured to receive photo-voltaic laminate panels 203.
• the embodiment of Figure 8 provides an advantage in that the application, servicing or removal of voltaic laminates 203 is easily facilitated, by the removal or application of the top sheet 801. Thus, the laminates 203 may be secured in position without affecting the integrity of the upper surface of the first sheet 301.
• Figure 9
• FIG. 9 A cross-section of the support frame is shown in Figure 9, substantially similar to the cross-section of Figure 4 but with an additional frame attachment to facilitate assembly of the configuration shown in Figure 8.
• Frame attachment 901 is secured to the upper frame component 401.
• the frame attachment 901 provides a first bead-channel 902 and a second bead-channel
• Each of these bead-channels is configured to receive a beaded edge of a third flexible sheet, such as sheet 801 shown in Figure 8.
• Figure 10
• FIG. 10 An alternative embodiment is shown in Figure 10, in which the first flexible sheet 301 is an outer sheet having an outer upper surface 501 and an inner surface 502.
• a first photo-voltaic laminate 203 is secured to the outer surface 501 , possibly using the techniques described with respect to Figure 5 or with respect to Figure 6.
• a second photo-voltaic laminate 1001 is secured to the intermediate sheet 303.
• a degree of shading is provided by both the upper photo-voltaic laminate 203 and the intermediate photo-voltaic laminate 1001.
• the shading regions are interdigitated such that the blank (substantially transparent) regions of the upper layer 501 are covered by the shading regions of the intermediate layer 303.
• FIG. 12 An alternative embodiment is shown in Figure 12, that is substantially similar to the embodiment of Figure 10.
• upper photo-voltaic elements 1201 and intermediate photo-voltaic elements 1202 have been incorporated within the cushion material itself, possibly using the techniques described with respect to Figure 7.
