With a KFW70 house, the annual primary energy demand of the Energy Saving Ordinance 2009 is undershot by 30%!
In relation to the reference house; the reference house equals 100%!
Energy Saving Ordinance 2014 from 01.01.2016:
• Reduce annual primary energy demand by an average of 25%!
• Increase thermal transmittance coefficient by an average of 20%!
From the Energy Saving Ordinance 2016 onwards, for example, a current Kfw 70 efficiency house must reduce the annual primary energy demand by an average of 25% and increase the thermal transmittance coefficient by an average of 20%.
That makes sense! It certainly won’t get cheaper; I would anyway doubt it being cost-neutral.
