Life Cycle Analysis (LCA), a kind of cradle–to–grave paradigm based instrument

for measuring the product sustainability by analyzing energy, cost, and environ-

mental impacts that would be spent and occur along the product–life–cycle, is

one of mechanisms used for Eco Labeling or Environmental Labeling, certifica-

tions of acknowledgement on sustainable product.

The labeling could possibly be carried out by way of kind of LCA instrument lim-

ited within economically established countries. What about sustainable architec-

ture, that would always be involving energy, cost, and environmental impacts as

well, as all we know architecture cannot separated from building in terms of

building as a product of architecture.

“System Approach to Architecture”, offered by A. Benjamin Handler, simplified

to considering architecture as a system practically based on paradigm that simi-

lar to LCA. System that consists of designing process, construction, facility op-

eration, and human bionomic process, will act as a building–life–cycle instru-

ment if at the end of the system completed with a building management system

or a system that concern about end of life of the building, such as recycling proc-

ess, renovation, or preservation. Toward

LIFE CYCLE ANALYSIS (LCA)

A WAY TOWARD

SUSTAINABLE PRODUCT

Life Cycle Analysis (LCA), a kind of instru-

ment based on cradle–to–grave paradigm

for measuring product sustainability by

analyzing the product–life–cycle, which

means along its life cycle a product should

be using either renewable or non–

renewable resources in a very sensible

way. LCA, also a popular term for who

concern about environmental issues, in

different phrase an instrument for im-

proving production process and its prod-

uct with the purpose of minimizing envi-

ronmental impacts particularly energy

and cost that would be spent along the

process, with the intention of logically

manage for effectiveness.
