7. Constructive solutions, insulation
The basic requirements for structural parts of the building are the following:
x high level of thermal insulation of building envelopes (with a coefficient of heat transfer U: walls - no more than
0,09 W/(m2
K), the coating is not more than 0.07 W/(m2
K), the floor is not more than 0,09 W/(m2
K);
x maximum the exception of thermal bypasses in the nodes and the abutting joins of selected design solutions;
x installation of translucent cladding structures with low-e coated glass (with a coefficient of heat transfer
U ≤ 1 W/ m2
K)
x high air tightness of building envelopes
x reliable insulation system, ensuring the caulking of butt joints and seams enclosing structures and components
during the lifetime of the building (over 30 years)
