I want to build a KfW40+ prefabricated house with a basement, two full floors, 12m by 8m. In the basement, I have technical equipment as well as a music room, with underfloor heating and connection to [Kontrollierte-Wohnraumlüftung]. The plot is flat.
Provider 1 said calculating the basement outside the thermal envelope is "better and cheaper," therefore there will be insulation between the basement ceiling and the ground floor, as well as insulation under the music room.
Provider 2 said to calculate the basement within the thermal envelope.
I tend to prefer Provider 2, as having the basement within the thermal envelope makes more sense to me. Also, I save on the extra insulation between the basement and the ground floor.
What do you think?
Thank you in advance.
