1. A portable building, comprising: at least one wall having a frame, a first insulation layer within or attached to the frame, and a second insulation layer separate from the first insulation layer, the second insulation layer being substantially rigid and fixed with respect to the frame exterior to the first insulation layer, wherein the second insulation layer and frame substantially prevent air flow through the first insulation layer, andan exterior shell having one or more vertical corrugations contacting a separate inner layer so that the inner layer is between the second insulation layer and the shell,wherein each of the vertical corrugations forms with the inner layer a respective vertical channel having openings to the atmosphere at a top and a bottom of the shell, each such vertical channel forming an air travel conduit adapted to allow air to flow through the openings and through such channel adjacent the inner layer, anda flashing overlapping and spaced from the top of the shell, wherein air rising through a respective vertical channel exits the top opening of the respective vertical channel to outside environment through a gap between the flashing and the shell. 2. The portable building of claim 1, wherein the inner layer is a one-way gas permeable layer. 3. The portable building of claim 2, wherein the inner layer is fixed with respect to an exterior of an insulation layer. 4. The portable building of claim 1, further comprising a floor having a frame, a first insulation layer within or attached to the floor frame, and a second insulation layer separate from the first insulation layer, wherein the floor's second insulation layer and frame substantially prevent air flow through the floor's first insulation layer. 5. The portable building of claim 4, further comprising a layer fixed exterior to the floor's second insulation layer and having an outward-facing reflective surface. 6. The portable building of claim 4, further comprising one or more ducts for one or both of heating and cooling, each of the ducts within the floor's frame and having multiple insulation layers. 7. The portable building of claim 6, wherein the multiple insulation layers include a layer having a reflective surface, the reflective surface facing outward from the duct. 8. The portable building of claim 6, wherein the floor's frame includes a series of joists extending along the longest dimension of the building, with each adjacent pair of joists separated by a distance, and wherein the one or more ducts are within one or more of the areas between adjacent joists. 9. The portable building of claim 4, wherein the floor is connected to the wall. 10. The portable building of claim 1, wherein the wall is an external wall. 11. The portable building of claim 10, wherein the wall is a side wall adapted to stand substantially perpendicular to the ground. 12. The portable building of claim 1, wherein the building is at least part of a permanent structure. 13. The portable building of claim 1, wherein the building is at least part of a semi-permanent structure. 14. The portable building of claim 1, wherein the building is at least part of a mobile structure. 15. The portable building of claim 1, further comprising a roof attached to the at least one wall. 16. The portable building of claim 1, further comprising one or more additional walls fixed with respect to the at least one wall to form a rectangular enclosure. 17. The portable building of claim 1, further comprising a gutter piece fixed with respect to the flashing, and wherein the flashing extends downward beyond the furthest extent of the gutter piece. 18. The portable building of claim 1, further comprising a floor attached to the at least one wall.
