Comparative overview of ANZCH scenarios

Scenario	Construction approach	Embodied carbon measures	Operational carbon measures
1: Entry level ANZCH	Conventional methods	10% fly-ash substitution in concrete Hollow bricks for walls Omission of exterior paint	Compact fluorescent lighting Solar-thermal geyser for domestic hot water
2: Hybrid ANZCH	Mix of conventional and innovative techniques	Cellular floor insulation Cross-laminated timber walls Monolithic roof system 30% fly-ash concrete Double-glazed aluminium windows	Low-flow hot water fixtures 3 kW PV system (450 W panels) generating 1 500 kWh annually (50% household electricity offset)
3: High-ambition ANZCH	Full adoption of innovative techniques	Autoclaved aerated concrete blocks Reused EPS insulation Hemp cladding tiles Cellulose ceiling insulation	Energy-efficient appliances On-site PV system producing 3 600 kWh annually (net-zero operational emissions)
