insulation, along with high-efficiency windows and other energy-saving
features, results in the buildings requiring only about one liter of
oil per square meter for annual heating — 5% of the average home
requirement in Germany, and well below the nation’s new efficiency
mandate of 7 liters per square meter.

The mandate is 65% reduction — no small thing. These folks are talking 95% reduction. Keep that in mind next time someone tells you “Can’t be done.”
