Hello everyone,
we are currently planning our semi-detached house.
Our semi-detached house is planned with 8 x 12 meters (12 meters is the side facing the neighbor) - 2 full floors, converted attic, basement. We want to build with brick (basement with white tank). Now a thermal insulation certificate has been calculated - also with regard to whether KfW 55 is an issue. The calculation was done with a 36.5 brick with lambda 0.09. Unfortunately, the transmission heat loss is still much too high for KfW 55. Even with a brick that, in my opinion, is great like S7 with 0.075 lambda, I would have no chance to reach KfW 55 (thickness 36.5). I would only reluctantly take a thicker brick, as that would reduce the living area.
Apparently, the A/V ratio is relatively poor with our semi-detached house.
Does anyone know such problems? Is KfW 55 more difficult to comply with in semi-detached houses or which adjustment options would need to be considered?
Thanks in advance for comments!
