Hello everyone!
When an energy consultant performs an energy performance calculation for a new build, is preparing the KfW 70 certificate still considered additional work that justifies extra costs?
Does anyone have cost estimates for energy consultant fees for a single-family house with 146 m² (1572 ft²) of living space plus 73 m² (785 ft²) of basement, once for just the energy performance calculation and once for the energy performance calculation plus the KfW 70 certificate?
The house has the following features:
- 17.5 cm (7 inches) calcium silicate brick, 20 cm (8 inches) insulation
- Geothermal system (brine-water heat pump with deep drilling, with a calculated annual performance factor of at least 4.5)
- Central controlled residential ventilation with heat recovery
- South-facing orientation
It should definitely meet the KfW 70 standard.
Best regards
