Reuse

A reuse level of between 20 and 40% would reduce the environmental footprint of the steel used in the building by 18 to 36%. This markedly improves the already strong position of steel when it comes to making life-cycle based decisions about material choices for new buildings. New practices developed for this project include: Development of a ...
