The embodied emissions invested in upgrading the home through a deep energy retrofit or a full reconstruction can be paid back in 5 years or less by the energy savings of a new high-efficiency home.

Concrete is the highest emitter and when possible, avoiding or reducing its use provides very high embodied emissions savings (in this case ~8 tonnes of CO2e)

40-80% reduction in embodied emissions can be easily achieved with simple material substitutions.

20 years of continued use for this home = the embodied emissions of 4 new net-zero homes.
