BUILDING–LIFE–CYCLE
Figure–2 below can give an explanation
about environmental impacts, which will
occur as consequences of building–life–
cycle as follow:
Cradle (i.e. Birth): Raw material accu-
sation will cause energy and cost us-
age besides environmental impact.
Products manufacture transportation:
idem ditto
Construction and fitting out: idem ditto
Operation and maintenance: will cause
operating energy and cost usage be-
sides environmental impact as well.
Grave: Renovation and demolition will
cause energy and cost usage besides
environmental impact.
To estimate the amount of energy that will
be used, there should be analysis on both
energy, which is integrated into building
and consumed along its life or for opera-
tional and maintenance purpose. Opera-
tion will depend on material usage and
fabrication methods, meanwhile mainte-
nance will depend on orientation, zone,
and kind of windows, building surface so-
phistication, and will depend on lighting
and air conditioning system, insulation,
thermal characteristics of wall and roof.
