The passive haus requirements do seem a bit strange, very tight heating/cooling limits but sloppy overall consumption limit.
We are well within the 120kwh/yr/m2 (around 70) and not far off the 15kwh/yr/m2 heating but our house is nowhere near PH standards in window or wall U values.
I remember some time ago reading there is a correction factor in the passive haus standard for climate, but have never been able to find any other reference or details on this. Anyone?
Also not too sure about how the heating requirement is implemented with regard to heat pumps? Is it just power from the grid that counts or heat pump output?
