“Tunneling through the cost barrier” in peer-reviewed studiesof ambitious European building retrofits
European retrofitted building savings reported 2006–13
(IPCC AR5 WG3 p 703), 3%/yreal discount rate over 30 y. Note that the better cases
show virtually no rise in cost up to >90% savings. Some
cost more, but they needn’t.
Sources: BP, except IEA for enewable heat. Electricity is shown at its heat value, 3.6 MJ/kWh, not at its primary input to an equivalent thermal power plant. Primary-to-final losses are not reflected.
IPCC AR5 WG3 pp 702–704 (2014) reports that high-ambition European new (left) and retrofit (right) buildings show no significant increase in the cost of saved energy up to ≥90% savings. Some examples do show higher costs, but they needn’t: whatever exists is possible.

German Technology for Electrified Carbon-Fiber Cars
BMW’s sporty, 1250-kg 4x-efficiency i3 was profitable from the first unit, because it: • pays for the carbon fiber by needing fewer batteries (which recharge faster) • saves ~2.5–3.5 kg total for each kg of direct weight saved • needs two-thirds less capital, ~70% less water, ~50% less energy, space, time • requires no conventional body shop or paint shop • provides clean, quiet, superior working conditions • delivers 1.9 L-equivalent/100 km (124 mpge) on US or 1.7 on German test cycle
