17 Lessons learnt in Switzerland 17 million of certified MINERGIE -Buildings have a value of 50 billion CHF and 7 million m 2 total surface of buildings in MINERGIE-Standard, not certified Reduced energy consumption by 130 mill. Liter oilequivalent/year Higher value of buildings from 3% (condominiums) to 6% (single family houses) Awaken the economical interest of the industry in energy efficient products Set-up the largest Swiss training organization in building sector Increased building industry by jobs (3%) 1) Swiss Building Industry: 300'000 yobs, added value 30 bill.
