By looking at the entire product life-cycle, we were able to choose materials for the Water Centre with the least impact on the environment and employee health. The following considerations were made in choosing materials:
All 700,000 kilograms of reinforcing steel used in construction came from recycled sources, using 1/4 the amount of energy needed to make new steel from iron ore.
We choose Fly-ash concrete because it requires fewer natural resources and releases less CO2 than concrete made with Portland cement. Approximately 30 per cent of the building's cement was replaced with fly-ash concrete, using 10 per cent less water than regular concrete.
The fabrics used in furniture and dividing panels are made of 100 per cent recycled materials. Work surfaces and the demountable wall system separating departments are manufactured locally.
