Sustainability is at the heart of 333 George Street, an 18-storey building in Sydney's CBD featuring a mix of retail and office tenants. Central to achieving the goal of achieving a 5 Star Green Star energy rating is the selection of Boral's innovative ENVISIA® concrete for the building's suspended post-tensioned floor plates, columns and core walls.
ENVISIA® is a lower carbon concrete with excellent performance benefits and plastic placement and finishing properties similar to conventional concretes
ENVISIA® allows less cement to be used in the concrete manufacturing process without impacting on performance
ENVISIA® achieves a Portland cement reduction of up to 65 per cent using the Green Star MAT-4 method without the traditional trade-offs in concrete performance
It outperforms conventional concretes in shrinkages and creep, providing up to 50 per cent reduction in shrinkage compared to conventional concrete
