30
%
of
the
impacts
originate
from
the
pre-­‐fabrication
of
the
building
elements
(A3),
their

transport
(A4),
and
the
processes
at
the
construction
site
(A5).

system.

Especially
remarkable
is
the
high
share
of
environmental
impacts
that
are
caused
by
the
transport

of
the
building
elements.
On
average,
walls,
roofs
and
ceilings
are
transported
to
the
construction

site
over
350
km
by
5
to
8
trucks.
For
the
delivery
the
trucks
require
around
884
l
diesel
on

average.
