The standard says,
- Space heating <= 15 kWh/m²/yr,
- an airtightness limit of 0.6ACH@50Pa (air changes per hour at 50 Pascals),
- total primary energy demand <= 60 kWh/m²/yr.
For our house, at 244m², this works out at:
- Heating <= 3,660 kWh over the year.
- Total primary energy need <= 14,640 kWh over the year.
