Retaining a heritage weatherboard frontage while upgrading to high-performance living, this Yarraville home pairs fabric efficiency with a low-carbon structure in Melbourne’s inner west. Holcim supplied ECOPact® for the slab and footings, cutting embodied carbon by at least 30% versus ordinary Portland cement concrete, while maintaining the strength, durability and finishability required for a Passive House-level upgrade.
The result is a resilient contemporary family home. The renovation features a future-focused foundation that supports comfort, energy efficiency and reduced upfront emissions. Passive house principles aim to improve the thermal envelope to reduce energy use while providing comfortable conditions year-round.
The ECOPact range can be used in a variety of structural components, such as foundations, columns, walls or driveways. It can also be handled, pumped and finished like conventional concrete.
