A shingle assembly for installation on a roof structure is provided. The shingle assembly can include an insulative substrate, a surface sheet coupled to and extending across a substantial portion of the insulative substrate, and a hook-and-loop fastening system comprising a hook portion and a loop portion. The hook portion or the loop portion can be coupled to and extend along the insulative substrate adjacent the surface sheet. The other of the hook portion or the loop portion can be coupled to and extend along the surface sheet. The hook portion can be configured to mate with a loop portion of a first adjoining shingle assembly and the loop portion can be configured to mate with a hook portion of a second adjoining shingle assembly.

A ventilated structural panel comprising a first sheet, having a long axis defining a length and a perpendicular short axis defining a width, a plurality of spacing structural elements, fixedly attached to the first sheet such that the yield strength of the panel is greater than the individual yield strength of the first sheet, and the plurality of spacing structural elements being formed such that a plurality of unobstructed pathways are created for air to move from at least one edge of the panel to at least one of an opposite and an adjacent edge of the panel, wherein the first sheet is the only sheet in the panel.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

Systems and methods for collecting solar energy and ambient heat are provided. A roof panel includes a metal sheet disposed about an upper end of the roof panel. Heat insulation is disposed below the metal sheet. At least one hot air duct and at least one cold air duct are each formed parallel to a rafter direction and in the plane of the roof panel. Each hot air duct is exposed to a surface of the metal sheet, and each cold air duct is encompassed by the heat insulation. A medium collectively fills the air ducts. A lower air reversing chamber is formed at a lower end portion of the roof panel, and an upper air reversing chamber is formed at an upper end portion of the roof panel. A cooling device is disposed in the upper air reversing chamber.

The invention relates to a roof forming element for a roof, comprising a roof plate, a beam integral with the roof plate, such that the integral combination of the roof plate and the beam has an L-shaped cross-section, a cover, and coupling means for coupling the roof forming element to a further, neighbouring element. The roof forming element, at least in a mounted condition of a plurality of such elements, is configured such that the second longitudinal side of the element is arranged to be supported by the first longitudinal side of a further, neighbouring one of said elements, so that the beam of the further roof forming element also supports the roof plate of the roof forming element, and so that the respective roof plate elements of said roof forming element and further roof forming element are flush with respect to each other.

The present invention discloses an improved light transmitting plastic panel (100) used in buildings for providing a variable daylight either during a day or in various areas of the building. The light transmitting plastic panel (100) consists of two transparent plates (102A, 102B) and a plurality of transparent hollow cells of V-type (104A, 104B) and rhombus shaped cells (106) located in between these plates (102A, 102B). In particular, a structure of the hollow cells is a repetitive sequence of one rhombus cell (106) in between two V-type cells (104A, 104B). Further, some of the hollow cells are made opaque with a predetermined pattern. With this specific structure, the variable daylight is achieved based on a time of day. In another aspect of the invention, differential daylight is provided for different areas of the building by forming a non-continuous flow pattern of opaque hollow cells across the length of the light transmitting plastic panel (100).

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

A self supporting panel system used to fabricate ceilings, floors, walls, or roofs. The panel system is assembled from a plurality of panels, each having a core that is sandwiched between opposing plate members. In a preferred embodiment, the core of each panel includes a unifying material to enhance the load bearing capacity of the panel.

The insulating barrier of a panel including has a first stratum and a second stratum, each having a plurality of ridges that face each other, and run athwart of each other. Clearance between at least some adjacent pairs of the ridges provide a mechanical chase that reaches across at least most of the panel. A cladding overlaying at least one side of the insulating barrier is denser than the barrier. The mechanical chase is in the form of a groove through which a utility feed can be routed when the panel is to be mounted in a building.
