A house which using brick cladding on con-
crete slab and steel sheet on steel roof
frame will need fewer energy compare to
usage of energy along its life, since almost
energy will be consumed for lighting, refrig-
erating, and/ or heating systems.
The most effective way to reduce a house-
hold life cycle is by using energy conserved
materials and system, which is needed
along the operational process. Solar pas-
sive design principles along with energy
conserved tools and lighting system is the
key factor with the intention of reduces
energy consumption, which produced CO
2
as well as consequences of the increasing
of energy production.
SYSTEM APPROACH TO ARCHITECTURE A
WAY TO SUSTAINABLE ARCHITECTURE
As an instrument for environmental man-
agement and decision making on produc-
tion processes, LCA denotatively showed
the relationship with global recovery, how-
ever in regard with entire network how
architecture will be related.
“System Approach To Architecture” simpli-
fied to “considering architecture as a sys-
tem” offered by A. Benjamin Handler
(Handler, 1970), that consists of four sub
systems: 1. Design Process; 2. Construc-
tion Process; 3. Operational Process; 4.
Human Bionomic Process, practically has
similar paradigm with LCA in regard with
solving architectural problems.
The entire processes carried out by the
four sub systems showed that architec-
tural system keep considering the life cy-
cle of its product in this case the building–
life–cycle, though has not included the
last process that will manage the building
at the end of its life. The later process can
be analogized with waste management of
LCA.
However, Handler explicitly has not stated
environmental impacts yet particularly as
result of consumption of energy and cost
