ZEBs – No Fundamental Progress Over the Last 25 Years?
Abstract
After the many ZEB /Zero Energy Building) attempts in the early nineties, the field stagnated. The new mantra became, better insulation. Nowadays ZEBs are being revisited as many passive and low energy building have been built and are apparently working well, although the debate on healthy or not indoor climate has increased as more and more „tight boxes“, all based on the same simple recipe; heavy insulation, heat recovery, new renewable energy - are being built.
