The landmark Moscone Convention Center in San Francisco, opened in 1981,  was recently given a makeover which integrated the colors and themes of northern California into the interior design. The lighting scheme highlights these design elements while being energy efficient, maintenance friendly and budget conscious. Since most spaces are underground, a primary goal was to create light, bright spaces where convention-goers would feel comfortable spending an entire day. This was the first West Coast convention center to earn LEED Gold for existing buildings.
