3.1.1 Green Factory
The vision of green factory
For the purpose of environmental coexistence and global
sustainable development, UMC joined “Green Factory
Promotion Association” in 2010 and is working with experts
from industry, government, and academia to build a green
building and green factory-clean production evaluation
system, aiming to establish "Green Factory Standards”
in Taiwan and expected to achieve the long-term goal of
"Green Park".

EEWH certification
UMC started evaluating the concept of Green Building in
2007. In 2008, Green Building certification programs were
formally adopted for Fab 12A P3&P4’s new construction.
From our past experience of energy conservation and
hiring external experts, we modified the original design
to meet LEED codes for U.S. green building council and
EEWD green building criteria in Taiwan. Fab 12A P3&P4
obtained both green building certification in 2011 and 2012.
Aside from green building design for new factories, we also
continue green transformation for existing factories.
For the original Fab 8A facility, which has been in operation
for more than 17 years, we still put forth efforts to innovate,
import new technologies, develop internal technologies
and self-administer environmental protection and energy
saving. Fab 8A was certified by the EEWH in 2012 as the
first 8” wafer fab to receive this in Taiwan.

"Green Building" Design
1.Ecological, green, water-retaining design
n Applied surrounding forest landscaping to decrease
impact on habitat migration
n Created ecological ponds for the purpose of both flood
detention and rain water reclamation
n Inter-lock brick type pavement was applied
n Used permeable sloping design for unexcavated areas
n Replaced conventional AC pavement design for all
internal access points to improve rain water retention
capability
2. Energy-saving air conditioning design
n Adopt VAV air conditioning systems in all offices
n Applied free-cooling control mode during the winter
season
n A comprehensive heat pump design has been introduced
across the board as a boiler auxiliary to retrieve cooling
loads back to the central chilled plant for water-return.
These have contributed greatly to annual natural gas
conservation.
3. Energy-saving lighting design
Fab 12A P3&P4 introduced energy-saving fluorescent
lamps with low-loss electronic ballast and metal halide
lamps to improve lighting controllability. These have made
huge contributions to annual energy conservation with the
same designed illumination.
4. Local renewable energy design
Fab 12A has installed the solar photovoltaic system. At
2012 the total electricity generation from the PV system
was 654,000kWH .
