If the exterior walls and the foundation plate are sur-
rounded with perimeter insulation, the earther the

foundation open the bottom.
To ensure contact with the earth, water-impermeable
concrete must not used.e.
If the building structure surrounded all sides by
perimeter insulation, i.
If the perimeter insulation only the surrounding
walls, earther contact often still intact.
Because the foundation earther longer has contact
with the earth here, additional grid ring earther
must created.4.4 Perimeter insulation
Perimeter insulation heat insulation, which sur-
rounds the area the structure contact with the
earth from outside. Connection
lugs must routed into the building such way
that they are resistant pressurised water above
the maximum groundwater level. The founda-
tion earther can implemented the concrete.4. functional equipotential bonding
