Frequently Asked Questions

Why does embodied CO2 matter?
Construction emits CO2 (cement, steel, glass production). Insulation foam: ~5 kg CO2 per kg material. Heat pump: ~5 tonnes embodied. Need to compare to operational savings to know real net climate benefit.
Typical payback ranges?
Cellulose insulation: 1-3 years. Heat pump replacing gas: 3-6 years. Triple-glazed windows: 5-10 years. Solar panels: 1-3 years. Anything over 10 years payback = climate-marginal investment.
What if I move?
CO2 payback follows the building, not the owner. Even if you move, the renovation continues to save CO2. Future occupants benefit. Doesn't change CO2 calculation, only your personal financial ROI.
