Sustainability as applied to building design is something
TI takes seriously. In the realm of construction, sustainability
is more than just a philosophy that acknowledges the need
to balance the requirements of people, profit, product and
the planet. The act of creating a sustainable building represents
a very practical and systematic application of modern technology.
In the U.S. alone, according to the U.S. Green Building Council,
buildings consume 12 percent of the potable water, 30 percent
of raw materials, 39 percent of all primary energy generation,
71 percent of electric consumption and produce 39 percent
of carbon emissions. Sustainable buildings are conceived with
particular emphasis placed on environmental and economic considerations
to help minimize these impacts.
A central plank in TI's green building strategy is our embrace
of principles defined by the U.S.
Green Building Council, which is the central advocate
of the Leadership in Energy and Environmental Design (LEED)
system. LEED standards go beyond simple regulatory standards
and deliver state-of-the-art systems, which push TI facilities
closer to our corporate goal of zero wasted resources.
We chose LEED for its overall credibility, high level of
adoption and rigorous standards. TI is seeking LEED certification
for both new construction (LEED-NC) and for existing buildings
TI became the first semiconductor manufacturer to comply
with LEED standards when we registered our Richardson, Texas,
facility, known as RFAB,
in 2004. By 2007, TI had registered five buildings with LEED,
and plans to certify existing buildings at all major TI sites
by 2011. TI will incorporate LEED construction principles
in all new building construction moving forward.
Benefits of sustainable design
TI seeks to incorporate green building concepts that holistically
acknowledge five target areas: sustainable sites, water efficiency,
energy and the atmosphere, materials and resources, and indoor
Sustainable building design improves the energy and water
efficiency of TI facilities, significantly reduces energy
consumption from lighting, diminishes rain runoff, and reduces
the urban heat island effect. It also reduces our direct and
indirect waste emissions and lightens our footprint on the
For example, when installing building water systems, TI observes
three "Rs" that are fundamental to effective sustainability:
reduce, reuse and recycle. Water need is reduced by utilizing
native landscaping and waterless urinals. Energy use reduction
also reduces the amount of water used for cooling.
Water reuse and recycling is employed in a number of areas
to further reduce the need. Some of these areas include capturing
rainwater and air-conditioning condensate for irrigation,
reclaiming water from manufacturing tools, and wastewater
used in scrubbers and cooling towers.
Some of the benefits from the sustainable design of RFAB
- Recycling 90 percent of the construction waste
- Cutting office lighting energy 80 percent by using natural
daylight and responsive lighting
- Reducing overall site energy use by more than 20 percent
and water use by more than 35 percent compared to a traditional
- Eliminating most of the natural gas boilers by employing
energy recovery from air compressors and chillers, resulting
in significant site emissions reductions
- A projected utility cost savings of $1 million in the
first year, which will increase to $4 million a year when
the building is fully operational

TI completed the world's first state-of-the-art new construction
"green" semiconductor manufacturing facility for about 30
percent less per square foot than our previous facility, which
is 10 years old and situated nearby.
In 2007, TI assessed other new construction activities for
LEED-based design. We are currently building two new green
facilities in the Philippines, one of which is slated to become
the country's first LEED-certified building. It was challenging
to apply LEED standards overseas, as designers and suppliers
were unfamiliar with the system. However, the teams have made
up for some of their lack of familiarity with a willingness
to embrace the concept, and are progressing on both projects.
For existing buildings, TI facilities personnel formed a
Green Solutions Team to extend LEED standards. TI also registered
an office complex with LEED for Existing Buildings (LEED-EB).
See chart below for progress details on reduced energy use.
We also are growing LEED expertise internally. Two additional
TIers passed the exam in 2007 to become LEED-accredited professionals
— one for new construction and one for existing buildings.
In 2008, TI will continue assessing how we can make our existing
buildings more sustainable and advance green building activities
in additional buildings.
Current LEED registered/certified projects
RFAB Admin building – Richardson, Texas, LEED-NC 2.1, 2004
RFAB wafer fab – Richardson, Texas, LEED-NC 2.1, 2004
TIPI Phase V assembly/test – Baguio, Philippines, LEED-NC
TI Clark assembly/test – Clark, Philippines, LEED-NC 2.2,
TI Spring Creek site – Plano, Texas, LEED-EB O&M, 2007
Although we have only recently begun our official LEED efforts,
we have worked to reduce energy consumption in our facilities.
This chart shows progress made over the past four years at
our first LEED-EB registered site. Adding variable speed drives,
upgrading lighting systems and adding demand-controlled ventilation
have already greatly improved our energy efficiency.
