Better building through design

Cambridge, U.K. — The construction industry, which uses half of the 1.5 billion tonnes of steel produced each year, could drastically reduce its carbon footprint by optimizing the design of new buildings to use less material, according to research from the University of Cambridge. Smart design could slash the sector’s carbon emissions by around 50 percent, without any impact on safety. If buildings are also maintained for their full design life and not replaced early, the sector's emissions could in total be cut by around 80 percent — the target set in the UK's 2008 Climate Change Act.
