Estimating embodied energies for building envelopes. The cladding of a framed building provides an envelope to protect it against the elements. It must do so while imposing as little additional dead load on the structural frame as possible, and it should enhance the architectural concept and appearance of the building. Alternative cladding materials include 1.5 mm aluminum sheet, 10 mm plywood, or 3 mm PVC. Use data from Chapter 15 to estimate the embodied energy per m²
of clad surface using each of these materials. Assume that the aluminum has a recycled content of 50% and that the other two materials have none.
