Some of the key ways we maximize energy efficiency include:
- Manufacturing equipment.
- Wafer fabrication is the most energy-intensive process at TI. Manufacturing tools directly consume more than 50 percent of a facility's total energy. And because we use energy-intensive point-of-use chillers and vacuum pumps at nearly every site, we phase in new, more efficient models where feasible.
- We look for methods to reduce the standby energy used by manufacturing equipment.
- Central utilities plant equipment.
- Our central plant equipment operations – chillers, boilers, pumps and cooling towers – constitute 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.
- We save 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 reduce the volume of exhaust required, which reduces the amount of fresh air that needs to be 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, we replace them with reflective roofs.
- In our new projects, we install well-insulated windows and walls.
- We carefully place and shade windows to reduce unwanted heat gain but preserve ample daylight.
- Lighting controls and sensors, many of which are made possible through our 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, we consolidate our data centers and upgrade 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.
- Central printers and scanners have replaced most desktop printers.
