1. Allowing for recycled content. Derive the correction factor to allow for recycled content cited in Exercise E10.1.

2. Estimating embodied energies for building structures. The following table lists the approximate mass of structural materials per m²
of floor space required for a steel and concrete-framed building and a wood-framed building. Assuming that the steel has 100% recycled content and that the concrete and wood have none, what are the embodied energies per m²
for the two alternative frames? To evaluate these take data for embodied energies of 100% recycled carbon steel and for virgin concrete and softwood from the data sheets of Chapter 15. Compare the resulting energies per m2 with the values from the LCA quoted in Table 10.6 of the text.
