Tall Buildings and Life Cycle Approaches: a debate that must be started

By means of life cycle assessment (LCA) and life cycle costing (LCC) analyses, the authors assess the environmental and economic impact occurring during the life cycle of different tall building structures n three macro-categories: all concrete, all-steel and concrete-steel composite. The study focused on three areas in Asia-Pacific: Bangkok and Singapore, markets with more recent experience of tall buildings and Sydney, where the market is mature. The research seeks to identify which could be the most advantageous comprehensive structural solution in terms of both sustainability and cost.
