Texas Instruments RFab
The 1.1 million-square-foot, 300mm Texas Instruments wafer fab complex, which has achieved Gold LEED certification for two buildings, was the first wafer fab facility to receive a LEED designation. The 92.4-acre campus includes a 220,000-square-foot ISO Class 5 turbulent clean room, 252,000-square-foot administration building, 171,000-square-foot support wing, 95,000-square-foot central utility plant and a 6,000-square-foot Bulk Gas Plant. Page, a design-build partner with Austin Commercial LP and Industrial Design Corporation, designed the complex of two buildings, the administration building and wafer fabrication building, with the initial goal of LEED Gold and Silver certification, respectively. After exhaustive research, design and implementation procedures by the design team, USBGC awarded both buildings LEED Gold ratings.
Innovative concepts were constantly explored, tested and re-tested to reduce, reuse and recycle building materials, natural resources and energy throughout the design, construction and occupancy phases of the project.
Some of the most notable innovations incorporated in the complex include:
- On-site retention pond, decreasing storm run-off and collecting rain to be reused for irrigation
- Windmill-powered aerator for the pond
- Native prairie grassland and vegetation, requiring little-to-no water or maintenance
- Reflective roofing membrane and concrete pavement, reducing urban heat island effect
- Waterless urinals, saving approximately 40,000 gallons per year per unit
- Faucets with sensors recharged by a small water turbine
- Split temperature chiller mechanical plant
- Heat recovery from the process compressed dry air (CDA) system
- Chillers, premium efficiency motors, highest efficiency fan filter units, make-up air energy recovery, run-around mechanical coils, and minimized pipe/duct friction
- Over 90 percent of construction waste diverted from landfills.
Sustainable innovations in the administration building include natural daylighting in occupied office areas, intelligent lighting controls with photo and motion sensors in each light fixture, solar water domestic hot systems, use of recycled materials and low emission materials.
In addition to architecture and interiors for both buildings, Page also provided MEP engineering services for the administration building and central utility plant, as well as structural engineering for the administration building. Page was also the design lead responsible for the Materials and Equipment Ready for Equipment Installation scope.
