Lightweight building assembly

A method of operating a lightweight building assembly, the method comprising:

• ventilating on either side of an insulation blanket of the lightweight building assembly, wherein the lightweight building assembly includes
• the insulation blanket, which defines an insulation blanket axis about which the insulation blanket is configured to rotate, the insulation blanket having a peripheral wall portion positioned at a radial distance from the insulation blanket axis, wherein the radial distance varies along a length of the insulation blanket axis,
• an insulation base coupled to and configured to support the insulation blanket, the insulation base having a first membrane,
• a frame coupled to and configured to support the insulation base, the frame having a second membrane, wherein the frame is configured to move with respect to the insulation base, and
• a plurality of tensioned elements wound about the insulation blanket, wherein each of the plurality of tensioned elements extends tangentially from the peripheral wall portion of the insulation blanket to the second membrane;
• ventilating between the first membrane and the insulation blanket;
• and
• ventilating between the second membrane and the insulation blanket.

A method of installing a lightweight building assembly within an overall building structure, the method comprising:

• providing an insulation blanket, the insulation blanket defining an insulation blanket axis about which the insulation blanket is configured to rotate, the insulation blanket having a peripheral wall portion positioned at a radial distance from the insulation blanket axis, wherein the radial distance is configured to vary along a length of the insulation blanket axis;
• coupling an insulation base having a first membrane to the insulation blanket;
• coupling a frame to the insulation base such that the frame is configured to move with respect to the insulation base;
• installing a plurality of tensioned elements about the insulation blanket such that each of the plurality of tensioned elements extends tangentially from the peripheral wall portion of the insulation blanket;
• and
• installing a second membrane to the frame such that the second membrane is at a distance above a floor of the overall building structure.
