Sustainable Materials and the Growing Importance of Embodied Carbon
84% of all building materials are ceramics (dominated by concrete), which compares with polymers (plastics) at only 1%. The use and manufacture of cement results in 5% of all anthropogenic carbon emissions.
Generally, 60% of energy is operating energy and 40% is embodies energy.
Stricter building regulations have reduced energy use, but generally increased building materials (e.g. insulation, PV cells etc.)
How can we reduce embodied energy?
Make buildings durable and beautiful so they last 200 years
