  • Location: Sunnyvale, CA
  • Building type(s): Commercial office
  • New construction
  • 585,000 ft2 (54,300 m2)
  • Project scope: 5-story building
  • Suburban setting
  • Completed 1983

In 1983, Lockheed Missiles and Space Company, Inc. (now Lockheed Martin) moved 2,700 engineers and support staff from an older office building on the Lockheed campus into the new Building 157.

Environmental Aspects

As predicted by the architect, Building 157 saved $500,000 in energy bills within the first year of occupancy due to the successful use of passive solar daylighting strategies in its design. A large central atrium (or "litetrium"), tall exterior windows, light shelves, and sloped ceilings were combined to provide enough high-quality daylight to reduce the building's artificial lighting use by 75%.

Building 157's energy savings were overshadowed, however, by an unexpected increase in employee productivity and decrease in absenteeism. Lockheed officials attribute this reinvigoration of their workforce to the design of the building. The focus on daylighting not only reduced energy costs, but also helped to create a pleasant, productive working environment.
