opted to emphasize
"green" building practices in its new South Astaire Building. This
three-story combination office building and movie/television set
serves as an expansion to Sony's main studio. A large central
skylight spills natural light into the building's open central
court.
The design team utilized a "task/ambient" lighting strategy to
reduce overall energy consumption. While ambient lighting accounts
for about 70 percent of the total lighting in the building,
individually controlled task lighting fixtures provide
complementary light directly on desks and displays. This strategy
usually provides sufficient illumination while using about
one-third less power than a standard recessed troffer system.
When lighting in the studio building meets target levels,
photosensors dim the lights in all offices and areas adjacent to
the central "light court." Along with daylighting controls, the
building features occupancy sensors in all the offices so lights
are turned off automatically in unoccupied spaces.
