Figure–2: Building–life–cycle

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
