Energy efficient building structure and panel therefor

Claim 2

An energy efficient building structure comprising: a plurality of structural panels wherein each panel includes a sheathed foam core formed into an open celled unit having a major expanse and a pair of flanges projecting from the plane of said expanse along opposite edges thereof, means securing a flange of each panel to an adjacent flange of another panel whereby the major expanses of said panels form an insulated self-supporting section of said building structure, covering members secured to the flanges of at least some of said panels generally parallel to the major expanses thereof to create closed cell units having air ducts therethrough, said building structure having an air flow loop extending between said ducts and another region of said building structure and being adapted to direct a flow of air through said loop. at least one of said closed cell units including heat transfer means for changing the temperature of air flowing through said loop in order to transfer heat to or from said region, and wherein said sheathed foam core limits heat transfer between the panel and said air flow to allow said air flow to rapidly transfer heat between said heat transfer means and said region.

Claim 3

An energy efficient building structure comprising: a plurality of structural panels wherein each panel includes a foam core formed into an open celled unit having a major expanse and a pair of longitudinally extending flanges projecting from the plane of said expanse along opposite edges thereof, an outer metal sheath covering a portion of said core and defining an outer surface and a portion of two substantially parallel and planar lateral surfaces of said panel, and an inner metal sheath covering the remainder of said core and defining an inner surface and the remaining portion of said lateral surfaces, each of said sheaths having a longitudinally extending edge along each of said lateral surfaces, one of said edges lying substantially in the plane of its associated surface, and the other of said edges being displaced inwardly from and extending in a substantially parallel, overlapping, spaced apart relationship with said one edge that protects said foam core while minimizing heat transfer between said outer sheath and said inner sheath, means securing a flange of each panel to an adjacent flange of another panel whereby the major expanses of said panels form an insulated self-supporting section of said building structure, covering members secured to the flanges of at least some of said panels generally parallel to the major expanses thereof to create closed cell units having air ducts therethrough, said building structure having an air flow loop extending between said ducts and another region of said building structure and being adapted to direct a flow of air through said loop, at least one of said closed cell units including heat transfer means for changing the temperature of air flowing through said loop in order to transfer heat to or from said region, and wherein said sheathed foam core limits heat transfer between the panel and said air flow to allow said air flow to rapidly transfer heat between said heat transfer means and said region.

Claim 4

An energy efficient building structure comprising: a plurality of structural panels wherein each panel includes a foam core formed into an open celled unit having a major expanse and a pair of longitudinally extending flanges projecting from the plane of said expanse along opposite edges thereof, an outer metal sheath covering a portion of said core and defining an outer surface and a portion of two substantially parallel and planar lateral surfaces of said panel, and an inner metal sheath covering the remainder of said core and defining an inner surface and the remaining portion of said lateral surfaces, each of said sheaths having a longitudinally extending edge along each of said lateral surfaces, one of said edges lying substantially in the plane of its associated surface, and the other of said edges being displaced inwardly from and extending in a substantially parallel, overlapping, spaced apart relationship with said one edge that protects said foam core while minimizing heat transfer between said outer sheath and said inner sheath, means securing a flange of each panel to an adjacent flange of another panel whereby the major expanses of said panels form an insulated self-supporting section of said building structure, covering members secured to the flanges of at least some of said panels generally parallel to the major expanses thereof to create closed cell units having air ducts therethrough, said building structure having an air flow loop extending between said ducts and another region of said building structure and being adapted to direct a flow of air through said loop, at least one of said closed cell units including heat transfer means for changing the temperature of air flowing through said loop in order to transfer heat to or from said region, and wherein said sheathed foam core limits heat transfer between the panel and said air flow to allow said air flow to rapidly transfer heat between said heat transfer means and said region.
