Hello everyone,
for our new building with 2 full floors and a cellar, we have now received a calculation for the entire Kfw application, but it seems to me that the values are calculated quite high, or even incorrectly.
A few data about the house:
Is that the electricity consumption I will need or am I misunderstanding something? That seems very high to me!
Thank you very much in advance.
for our new building with 2 full floors and a cellar, we have now received a calculation for the entire Kfw application, but it seems to me that the values are calculated quite high, or even incorrectly.
A few data about the house:
[*]Specifications from the architect's plan living area ground floor 75sqm & upper floor 70sqm (air space hence the difference)
[*]Clear height ground floor 2.7m & upper floor 2.5m
[*]Cellar not heated, air-water heat pump in the cellar.
[*]Attic not developed
[*]Air-water heat pump with ventilation system with heat recovery
[*]The expert appraiser comes to 277sqm usable area, that seems very high to me! He then continues to calculate based on that for electricity consumption and comes to a final energy demand of 4860kW/a
Is that the electricity consumption I will need or am I misunderstanding something? That seems very high to me!
Thank you very much in advance.
