Increasing efficiency

• Manufacturing equipment. Wafer fabrication is the most energy-intensive process at TI. Manufacturing tools directly consume more than 50 percent of total facility use. As energy-intensive point-of-use chillers and vacuum pumps are used at nearly every site, we phase in new, more efficient models where feasible. We also look for methods to reduce the standby energy used by manufacturing equipment.
• Central utilities plant equipment. With chillers, boilers, pumps and cooling towers, our central plant equipment operations are the second most energy-intensive process at TI. Our facilities' conservation teams routinely evaluate the efficiency of this equipment. They retrofit, replace or change components where cost-effective.
• Heating, ventilation and air conditioning. TI saves energy by replacing or upgrading air handling units, fans, coils and valves, as well as control equipment. In many cases, we reduce energy consumed by existing equipment simply by changing control programming. We also have found ways to reduce the volume of exhaust required, which reduces the amount of fresh air drawn in and its associated energy consumption.
• Building envelopes. Using a reflective roof to reduce heat gain is an effective reduction strategy. As existing roofs age, TI replaces them with reflective roofs. In our new projects, we also install well-insulated windows and walls. Additionally, we carefully place and shade windows to reduce unwanted heat gain but preserve ample day lighting.
• Lighting. Lighting controls and sensors - many of which are made possible through TI technology - are among the more cost-effective approaches to saving energy. We continually upgrade to more efficient fixtures to reduce consumption and have begun to install LED lighting in certain areas.
• Data centers, office and computer equipment. Although they collectively consume only about 5 percent of our global energy footprint, TI consolidates our data centers and upgrades servers, when feasible, to lower their energy use. The continued migration to laptop and LCD monitors has helped reduce energy use in our offices, along with updating energy-saving settings on computers. In addition, central printers and scanners have replaced most desktop printers.
